StripPrefix 篩選器

StripPrefix 篩選器接受一個參數，parts。parts 參數指示在將請求向下游發送之前，要從路徑中剝離的部分數量。以下列表設定了 StripPrefix 篩選器

application.yml
spring:
  cloud:
    gateway:
      mvc:
        routes:
        - id: nameRoot
          uri: https://nameservice
          predicates:
          - Path=/name/**
          filters:
          - StripPrefix=2
GatewaySampleApplication.java
import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.stripPrefix;
import static org.springframework.cloud.gateway.server.mvc.handler.GatewayRouterFunctions.route;
import static org.springframework.cloud.gateway.server.mvc.handler.HandlerFunctions.http;

@Configuration
class RouteConfiguration {

    @Bean
    public RouterFunction<ServerResponse> gatewayRouterFunctionsStripPrefix() {
		return route("nameRoot")
				.GET("/name/**", http("https://example.org"))
					.before(stripPrefix(2))
					.build();
    }
}

當通過閘道器向 /name/blue/red 發出請求時，向 nameservice 發出的請求看起來像 nameservice/red。
