spring cloud gateway和nigix 路由轉發時攜帶域名頭信息

1.nigin添加一段配置

  server {
        listen 80; 
        # this is the key !!!!!  proxy_set_header Host $host; location /client/pids { proxy_pass http://10.103.13.103:3200/client/pids; } location /interface/client/pids { proxy_pass http://10.103.13.103:3200/interface/client/pids; } ......

2.gateway網關配置

有一個過濾器PreserveHostHeaderGatewayFilter，用來在gateway轉發請求的時候把原始請求的host頭部帶上，轉發給目標服務。

- id: auth-service
  uri: lb://auth-service
  predicates:
    - Path=/api/auth/**,/api/oauth/dd/**
  filters:
    - StripPrefix=1
    - PreserveHostHeader #發送網關原始主機頭:
