If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. responseCode; responseHeaderTransformations; responseMessage; type; . The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. How does it work? If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. The collection of filters applied to the route. If You Appreciate This, You Can Consider: We are thankful for your never ending support. Modifying the request body is a common requirement. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. Easy to extend and/or customize using standard Spring patterns XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/1/ or /red/blue or /blue/green. ServerHttpResponse interface. Naming Custom Filters And References In Configuration, 18. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. 25Modify Response Body GatewayFilter Factory; If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. This predicate matches cookies that have the given name and whose values match the regular expression. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. URI variables may be used in the value and are expanded at runtime. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. All. Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. 4.1. connect-timeout must be specified in milliseconds. URI variables may be used in the value and are expanded at runtime. Acompanhe-nos: can gabapentin help with bell's palsy Facebook To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. The following example configures /actuator/gateway/routes: This feature is enabled by default. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). The maxSize parameter is the maximum data size allowed by the request header (including key and value). If so, the same rules apply. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. Here is a link to someone asking about ordered filters that may provide more insight: #1341. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. Spring Cloud Gateway includes many built-in GatewayFilter Factories. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. Modifying the Way Remote Addresses Are Resolved, 5.12. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. Since the request can be read only once, we need to cache the request body. The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. /resource). For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. With MVC, it also supports forwarding to a local handler through the forward() method. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. It does not work in a traditional Servlet Container or when built as a WAR. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. must be in a class named SomethingGatewayFilterFactory. the ID of the service from the DiscoveryClient. If it is not matched, the filter does nothing. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. SetResponseHeader is aware of URI variables used to match a path or host. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. You can read more about them in the. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. exceptions: A list of thrown exceptions that should be retried. If the new named header already exists, its values are augmented with the new values. Options. Writing Custom Route Predicate Factories, 17.2. Removes an existing route from the gateway. This handler runs the request through a filter chain that is specific to the request. By clicking Sign up for GitHub, you agree to our terms of service and The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. Getting the refreshTokenMono is webclient call which is in a different service.. By the time it gives the response, main response is already about to commit and wont allow us to modify the response headers. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The RequestRateLimiter is not configurable with the "shortcut" notation. You can also manipulate response headers (and anything else you like in the response) by adding a mapper to the get() method (and other methods). The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. Configuring Predicates and Filters For, 15.4. The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. outcome: The outcome, as classified by HttpStatus.Series. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. In configuration, you can reference the bean by name using SpEL. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. application.yml. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. This type of Repository is not suited to populate Routes across multiple Gateway instances. To clear the routes cache, make a POST request to /actuator/gateway/refresh. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. There should be no reason why a filter cannot modify a response header. Then the proxy request is made. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. The AddRequestHeader GatewayFilter factory takes a name and value parameter. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). The following example configures an AddRequestHeadersIfNotPresent GatewayFilter: This listing adds 2 headers X-Request-Color-1:blue and X-Request-Color-2:green to the downstream requests headers for all matching requests. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. The status parameter should be a 300 series redirect HTTP code, such as 301. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. All of these predicates match on different attributes of the HTTP request. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Some situations necessitate reading the request body. In future milestone releases, there will be some KeyResolver implementations. It is the permissible size limit of the request defined in bytes. If youre using load-balanced routes, you need to explicitly define your. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. While a Gateway is running you can use kubectl scale to modify the number of replicas. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . .application.yml. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. Zuul profile. It runs after all other filters have completed and writes the proxy response back to the gateway client response. So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. This is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. response-timeout must be specified as a java.time.Duration. backoff: The configured exponential backoff for the retries. To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services The XForwarded Remote Addr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). NEVER_STRIP: The version is not stripped, even if the original request path contains no version. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. Once a request has been marked as routed, other routing filters will not route the request again, The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. it is proxying. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. . By default, if the KeyResolver does not find a key, requests are denied. This strips the service ID from the path before the request is sent downstream. I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. Spring Cloud Gateway. The pattern is an Ant-style pattern with . A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. This predicate matches requests that happen before the specified datetime. There are many caching cases on the network, but there are various Bug problems in the testing process. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. GitHub spring-cloud / spring-cloud-gateway Public Notifications Fork 2.9k Star 3.9k Code Issues 337 Pull requests 39 Actions Projects Security Insights New issue How to modify spring cloud gateway response headers #1092 Closed For the external controller/handler scenario, headers can be added with exception details. URI variables may be used in the value and will be expanded at runtime. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. Service 4.3. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. I suppose your issue may have been different than mine, but when I turned on trace logging I saw that my filter was executing after the response was sent and so I gave the filter a different order value that put it in the right order. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. Usually it's a common requirement that applications can . This paper will introduce its usage in detail. The path part of the request URL is overridden with the path in the forward URL. That is not a complete working sample, it is just some code. spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). Tripping The Circuit Breaker On Status Codes, 12.4.1. It offers a simple way to manipulate the request path by allowing templated segments of the path. Those values are then available for use by GatewayFilter factories. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. .filters(f -> f.addRequestHeader("header1", "header-value-1")) For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . It uses the Netty HttpClient to make the downstream proxy request. This can be used with reverse proxies such as load balancers or web application firewalls where It is the name of the header to be removed. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. Those values are then available for use by GatewayFilter factories. To configure Global http timeouts: 3,AddResponseHeader GatewayFilter Factory. Already on GitHub? httpMethod: The HTTP method used for the request. 1. The gateway maintains a client pool that it uses to route to backends. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). GitHub Gist: instantly share code, notes, and snippets. You must use $\ to mean $ because of the YAML specification. Want to remove the "warning cannot modify header information" error from your WordPress website? For example, setting replenishRate=1, requestedTokens=60, and burstCapacity=60 results in a limit of 1 request/min. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). This predicate extracts the URI template variables (such as sub, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. 2016-10-05: 4.3: CVE-2016-6426 CISCO You can extend an abstract class called AbstractGatewayFilterFactory. Sharing Routes between multiple Gateway instances, 17.1. After the proxy request is made, the post filter logic is run. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. Raw. A route is matched if the aggregate predicate is true. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. The Between route predicate factory takes two parameters, datetime1 and datetime2 To write a custom global filter, you must implement GlobalFilter interface as a bean. The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. Am I doing it wrong? The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. status codes that if returned will cause the circuit breaker to be tripped. The resulting response is similar to the following: The response contains the details of the global filters that are in place. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$filter$0(CORSFilter.java:84) ~[classes/:na] at reactor.core.publisher.MonoRunnable.call(MonoRunnable.java:73) ~[reactor-core-3.2.8.RELEASE.jar:3.2.8.RELEASE]. to the exchange attributes. The body is cached in a request attribute defined by. If it is not provided, the value of the Host request header is used. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. However, there is one in another application, registered under localhost:9994. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. .metadata(RESPONSE_TIMEOUT_ATTR, 200) Spring Cloud Gateway includes many built-in route predicate factories. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted This is the number of tokens the token bucket can hold. In some cases you might want to trip a circuit breaker based on the status code When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON.
