StripPrefix GatewayFilter Factory

StripPrefix GatewayFilter 工厂采用一个参数 parts。parts 参数指示在将请求发往下游之前要从路径中移除的部分数。以下清单配置 StripPrefix GatewayFilter：

The StripPrefix GatewayFilter factory takes one parameter, parts. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. The following listing configures a StripPrefix GatewayFilter:

application.yml
spring:
  cloud:
    gateway:
      routes:
      - id: nameRoot
        uri: https://nameservice
        predicates:
        - Path=/name/**
        filters:
        - StripPrefix=2

当通过网关向 /name/blue/red 发出请求时，向 nameService 发出的请求看上去就像 https://nameservice/red。

When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like https://nameservice/red.
