The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. as the separator. If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. application.yml. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted That is not a complete working sample, it is just some code. URI variables may be used in the value and are expanded at runtime. Policy to specify how to modify the response code, body and headers. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. If the new named header already exists, its values are augmented with the new values. There are convenience methods that you can use to mark an exchange as routed The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. 1. This section covers common problems that may arise when you use Spring Cloud Gateway. The weights are calculated per group. response-timeout must be specified in milliseconds. In future milestone releases, there will be some KeyResolver implementations. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. So, if the downstream server responded with X-Response-Red:1234, it will be replaced with X-Response-Red:Blue, which is what the gateway client would receive. Easy to extend and/or customize using standard Spring patterns 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. the request should only be allowed if it comes from a trusted list of IP addresses used by those reverse proxies. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. status codes you want to trip the circuit breaker you can either use an integer with the status code Usually it's a common requirement that applications can . The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. If it is not matched, the filter does nothing. The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. Tripping The Circuit Breaker On Status Codes, 12.4.1. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. let's see. Retrieving Information about a Particular Route, 15.6. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. See the documentation for @RequestMapping in Spring MVC for more details of those features. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. To clear the routes cache, make a POST request to /actuator/gateway/refresh. The maxSize parameter is the maximum data size allowed by the request header (including key and value). To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java, @ryanjbaxter it seems a route filter,can i modify a response header in a global post filter,thanks. The url parameter should be a valid URL. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. It runs after all other filters have completed and writes the proxy response back to the gateway client response. By default, if the KeyResolver does not find a key, requests are denied. 3,AddResponseHeader GatewayFilter Factory. Typically, there will be a name key and an args key. Route: The basic building block of the gateway. URI variables may be used in the value and will be expanded at runtime. The Since the request can be read only once, we need to cache the request body. AddResponseHeader is aware of URI variables used to match a path or host. By default, it creates a NettyChannel by using the default TrustManagerFactory. To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. GitHub Gist: instantly share code, notes, and snippets. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. privacy statement. Configure for High Availability. This filter (which configures the local response cache per route) is available only if the local response global cache is enabled. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. Already on GitHub? Code Revisions 1 Stars 14 Forks 3. A utility method (called get) is available to make access to these variables easier. return routeBuilder.routes() Creating and Deleting a Particular Route, 15.8. The resulting response is similar to the following: The response contains the details of the global filters that are in place. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. Created 6 years ago. Note that the $ should be replaced with $\ because of the YAML specification. If youre using load-balanced routes, you need to explicitly define your. There is an abstract class called AbstractRoutePredicateFactory which you can extend. URI variables may be used in the value and are expanded at runtime. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. All. A number of timeouts are associated with this handshake. 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; . This handler runs the request through a filter chain that is specific to the request. 25Modify Response Body GatewayFilter Factory; 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 Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. 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. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). The status parameter should be a 300 series redirect HTTP code, such as 301. The RemoveHopByHop Headers Filter removes headers from forwarded requests. 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. To configure per-route timeouts: Currently, only forward: schemed URIs are supported. The most noteworthy thing here is: ServerHttpRequest or HttpMessage interface provides a method to get the request headers HttpHeaders getHeaders(); returns a read-only instance, specifically of type ReadOnlyHttpHeaders, mentioned here more than once I wrote this blog post using Spring Cloud Gateway version Greenwich.SR1. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The DedupeResponseHeader filter also accepts an optional strategy parameter. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). .metadata(RESPONSE_TIMEOUT_ATTR, 200) These are special filters that are conditionally applied to all routes. .route("test1", r -> { This uses Java regular expressions for a flexible way to rewrite the request path. To disable it, set the following property: This will default to true in a future release. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). A per-route response-timeout with a negative value will disable the global response-timeout value. The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. Spring Cloud Gateway includes many built-in GatewayFilter Factories. To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. This uses the URI templates from Spring Framework. The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Once a request has been marked as routed, other routing filters will not route the request again, The Reactor Netty HttpClient and HttpServer can have wiretap enabled. Refresh the page, check Medium 's site status, or find something interesting to read. It does not work in a traditional Servlet Container or when built as a WAR. or check if an exchange has already been routed. 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. 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. This predicate matches requests that happen after datetime1 and before datetime2. The headers with the exception type, message and (if available) root cause exception type and message are added to that request by the FallbackHeaders filter. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. Options. SetRequestHeader is aware of URI variables used to match a path or host. The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. which are java ZonedDateTime objects. If it is not provided, the value of the Host request header is used. The following listing configures a RequestHeaderSize GatewayFilter: This will send a status 431 if size of any request header is greater than 1000 Bytes. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). 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. 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. Writing Custom GatewayFilter Factories, 17.2.1. 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. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. The pattern is an Ant-style pattern with . To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. It uses Java regular expressions for a flexible way to rewrite the response header value. Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. keyResolver is a bean that implements the KeyResolver interface. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). The request returns a 200 without a response body. 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. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. Want to remove the "warning cannot modify header information" error from your WordPress website? 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. Spring cloud gateway response body modification. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. 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). 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. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). Some situations necessitate reading the request body. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. NOTE: This is not recommended for production. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. This predicate matches requests that happen after the specified datetime. Properties. So a request to /hello is sent to /mypath/hello. ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. For relative redirects, you should use uri: no://op as the uri of your route definition. 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 It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. 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. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. The following example configures a header route predicate: This route matches if the request has a header named X-Request-Id whose value matches the \d+ regular expression (that is, it has a value of one or more digits). Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. Both offer the same possibilities. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. After the proxy request is made, the post filter logic is run. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? 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. Here is a link to someone asking about ordered filters that may provide more insight: #1341. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. You can combine multiple route predicate factories with logical and statements. consumer can be a pure Client (like an SSO application) or a Resource This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. You can configure the logging system to have a separate access log file. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. The following listing configures a SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. 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].
