It runs after all other filters have completed and writes the proxy response back to the gateway client response. Predicate: This is a Java 8 Function Predicate. The ServerHttpResponse instance is used to . The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. These are basic guides to writing some custom components of the gateway. 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. The default request size is set to five MB if not provided as a filter argument in the route definition. 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. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. exceptions: A list of thrown exceptions that should be retried. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). Response data is not cached if Cache-Control header does not allow it (no-store present in the request or no-store or private present in the response). This vulnerability is known as HTTP Response Splitting. None of the prior documentation applies to what follows. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. 1050. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. 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. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. Modifying the request body is a common requirement. 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. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. 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. Have a question about this project? The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. 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. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. 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). status codes that if returned will cause the circuit breaker to be tripped. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. 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. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. This predicate matches requests that happen after datetime1 and before datetime2. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. .metadata(CONNECT_TIMEOUT_ATTR, 200); For relative redirects, you should use uri: no://op as the uri of your route definition. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. This is the value of the Location header. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. To configure Global http timeouts: For the external controller/handler scenario, headers can be added with exception details. The lowercase full name of the secure header needs to be used to disable it.. The There are convenience methods that you can use to mark an exchange as routed AS_IN_REQUEST: The version is stripped only if the original request path contains no version. A route is matched if the aggregate predicate is true. Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. The Between route predicate factory takes two parameters, datetime1 and datetime2 The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. 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. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). 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. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, 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. Route: The basic building block of the gateway. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. If the information is not provided within the next 7 days this issue will be closed. Both offer the same possibilities. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. 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 Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). 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. 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. Passing headers with Spring Cloud Feign. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. It uses the Host header, scheme, port and path of the current request to create the various headers. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. Spring Cloud Gateway. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. This interface and its usage are subject to change in future milestone releases. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. Acompanhe-nos: can gabapentin help with bell's palsy Facebook By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. Refresh the page, check Medium 's site status, or find something interesting to read. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. responseCode; responseHeaderTransformations; responseMessage; type; . The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. The pattern is an Ant-style pattern with . 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. as the separator. status: The HTTP status of the request returned to the client. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). 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. it is proxying. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. . pass the authentication token downstream to the services (in this case AddResponseHeader is aware of URI variables used to match a path or host. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. 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). Spring cloud gateway response body modification. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. To clear the routes cache, make a POST request to /actuator/gateway/refresh. Generally, it will put the identity information into the request header and will not modify the content of the request and response. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). URI variables may be used in the value and will be expanded at runtime. We do this already Zuul profile. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. When setting the A per-route response-timeout with a negative value will disable the global response-timeout value. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. Those values are then available for use by GatewayFilter factories. The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. Spring Cloud Gateway includes many built-in route predicate factories. privacy statement. application.yml. This type of Repository is not suited to populate Routes across multiple Gateway instances. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. I got the root cause. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. API gateway provides a unified access for services in microservices architecture. A Token Relay is where an OAuth2 consumer acts as a Client and backoff: The configured exponential backoff for the retries. Created 6 years ago. Modifying the Way Remote Addresses Are Resolved, 5.12. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. .filters(f -> f.addRequestHeader("header1", "header-value-1")) If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. Writing Custom GatewayFilter Factories, 17.2.1. Here, you can modify requests and responses before or after sending the downstream request. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Code Revisions 1 Stars 14 Forks 3. It is the name of the query parameter to be removed. 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 path part of the request URL is overridden with the path in the forward URL. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. 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. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. The gateway maintains a client pool that it uses to route to backends. .metadata(RESPONSE_TIMEOUT_ATTR, 200) The DedupeResponseHeader filter also accepts an optional strategy parameter. For example, to reference a filter named Something in configuration files, the filter Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium status codes you want to trip the circuit breaker you can either use an integer with the status code The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Raw. or check if an exchange has already been routed. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. response-timeout must be specified as a java.time.Duration. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. 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. A number of timeouts are associated with this handshake. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. SetRequestHeader is aware of URI variables used to match a path or host. In Any otherway is there apart from blocking call? The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. 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 disable it, set the following property: This will default to true in a future release. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. the request should only be allowed if it comes from a trusted list of IP addresses used by those Those values are then available for use by GatewayFilter factories. Naming Custom Filters And References In Configuration, 18. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. It uses the Netty HttpClient to make the downstream proxy request. Here is a link to someone asking about ordered filters that may provide more insight: #1341. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. 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. if. If the response is already cached and a new request is performed with no-cache value in Cache-Control header, it returns a bodiless response with 304 (Not Modified). Configure for High Availability. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. 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. httpStatusCode: The HTTP Status of the request returned to the client. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. All pre filter logic is executed. 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. Policy to specify how to modify the response code, body and headers. 4.1. GitHub Gist: instantly share code, notes, and snippets. If youre using load-balanced routes, you need to explicitly define your. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. The weights are calculated per group. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. The datetime2 parameter must be after datetime1. public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ 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). The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? Each item defines the name and the arguments of a given predicate. essentially skipping the filter. The default is 'B' for bytes. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. It offers a simple way to manipulate the request path by allowing templated segments of the path. Add a response header named X-Request-Foo with a value of Bar to the original response. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. .uri("http://someuri") This paper will introduce its usage in detail.
