outcome: The outcome, as classified by HttpStatus.Series. That is not a complete working sample, it is just some code. The maxSize parameter is the maximum data size allowed by the request header (including key and value). The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. It must be a valid Spring HttpStatus. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. 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. However, there is one in another application, registered under localhost:9994. Sign in If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. For example, given a Gateway that has 1 replica, the following will . If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. If You Appreciate This, You Can Consider: We are thankful for your never ending support. The first one is the To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. 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. Configuring Predicates and Filters For, 15.4. The pattern is an Ant-style pattern with . This predicate matches with a header that has the given name whose value matches the regular expression. If the input header does not exist, the filter has no impact. 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 lowercase full name of the secure header needs to be used to disable it.. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. The status parameter should be a 300 series redirect HTTP code, such as 301. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). *) and the replacement /${remaining}. 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. 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; . 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]. In order to modify APIcast behavior with custom policies, you must do the following: Add custom policies to APIcast Define a policy chain that configures APIcast policies Add the policy chain to APIcast 4.1. 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. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. 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. if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). 2016-10-05: 4.3: CVE-2016-6426 CISCO The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The KeyResolver is a simple one that gets the user request parameter This vulnerability is known as HTTP Response Splitting. Policy to specify how to modify the response code, body and headers. You can extend an abstract class called AbstractGatewayFilterFactory. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The following example configures /actuator/gateway/routes: This feature is enabled by default. The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. AddResponseHeader is aware of URI variables used to match a path or host. This is the value of the Location header. It uses the Netty HttpClient to make the downstream proxy request. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The default is http|https|ftp|ftps. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. Displays the list of GatewayFilter factories applied to a particular route. The DedupeResponseHeader filter also accepts an optional strategy parameter. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. regexp, so green and greet would match. pass the authentication token downstream to the services (in this case httpMethod: The HTTP method used for the request. See the documentation for @RequestMapping in Spring MVC for more details of those features. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. 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. 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. .metadata(CONNECT_TIMEOUT_ATTR, 200); methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. cloudflare tunnel home assistant 19 3407 . The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. 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. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. Well occasionally send you account related emails. The RemoveRequestHeader GatewayFilter factory takes a name parameter. This is the number of tokens taken from the bucket for each request and defaults to 1. 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. The arguments are typically listed in the order that are needed for the shortcut configuration. Tripping The Circuit Breaker On Status Codes, 12.4.1. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. By default, it creates a NettyChannel by using the default TrustManagerFactory. This predicate matches cookies that have the given name and whose values match the regular expression. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. It uses the Host header, scheme, port and path of the current request to create the various headers. 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 future milestone releases, there will be some KeyResolver implementations. This interface and its usage are subject to change in future milestone releases. Am I doing it wrong? URI variables may be used in the value and are expanded at runtime. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). 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. The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. The args key is a map of key value pairs to configure the predicate or filter. If youre using load-balanced routes, you need to explicitly define your. Modify request body. The RemoveRequestParameter GatewayFilter factory takes a name parameter. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. Naming Custom Filters And References In Configuration, 18. 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). GitHub Gist: instantly share code, notes, and snippets. By clicking Sign up for GitHub, you agree to our terms of service and .uri("http://someuri") 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 route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. To configure per-route timeouts: 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. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. This is of particular use when using something like Spring Session with a lazy data store, and you need to ensure the session state has been saved before making the forwarded call. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. So a request to /hello is sent to /mypath/hello. 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. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. @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? The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. 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 following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. The weights are calculated per group. Refresh the page, check Medium 's site status, or find something interesting to read. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services . 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. Easy to extend and/or customize using standard Spring patterns Properties. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. Typically, there will be a name key and an args key. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. Spring cloud gateway response body modification. 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. A burst of 20 is allowed, but, in the next second, only 10 requests are available. AddRequestParameter is aware of the URI variables used to match a path or host. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. 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. For a full working sample see this project. also note that the gist doesn't take the decoders into account from upstream like here. Service 4.3. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. The path part of the request URL is overridden with the path in the forward URL. While a Gateway is running you can use kubectl scale to modify the number of replicas. When setting the The ServerHttpResponse instance is used to . This predicate matches requests that happen before the specified datetime. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. 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.) Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. GatewaySampleApplication.java. This lets you match on anything from the HTTP request, such as headers or parameters. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted 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. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. 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). Fork 3. 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. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. 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 You can configure the logging system to have a separate access log file. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is Cleanliness 4.4. 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. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). The Between route predicate factory takes two parameters, datetime1 and datetime2 This predicate matches requests that happen after the specified datetime. 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. 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). URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. Writing Custom GatewayFilter Factories, 17.2.1. response-timeout must be specified in milliseconds. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. application.yml. 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). The RemoteAddr 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). Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium A Token Relay is where an OAuth2 consumer acts as a Client and To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. 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. Created 6 years ago. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. /resource). Modifying the request body is a common requirement. 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. 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. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. Setting this value to zero blocks all requests. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. if.
