我在详细说下：
第一步：http://localhost:9000/authorization/oauth/authorize?client_id=back&response_type=token 9000这个是网关服务，

 routes:
        - id: authorization
          uri: lb://authorization-server
          predicates:
          - Path=/authorization/**
          filters:
            - StripPrefix=1

第二步：跳转到授权服务/login,正常登录成功之后应该调回 http://localhost:8300/oauth/authorize，点击授权然后跳转到项目returnurl，但是跳转不回去了。
