nginx给需要转发的链接添加参数（Nginx 根据URL带的参数转发的实现）

server {
  listen 83;
  server_name localhost;
  index index.html index.htm;

  root D: /workspace-xxxx/xxx_Web;

  error_page 500 502 503 504 / 50x.html;
  location = /50x.html {
      root  html;
    }
  location ^~ /xxx/ {
    proxy_pass http: //192.168.60.36:8090/xxxx/;
    proxy_redirect default;
    proxy_set_header Host $host;
    proxy_set_header X - Real - IP $remote_addr;
    proxy_set_header X - Forwarded - Host $host;
    proxy_set_header X - Forwarded - Server $host;
    proxy_set_header X - Forwarded - For $proxy_add_x_forwarded_for;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
  }

# 此处为截取请求地址中bimg4之后的路径，并赋给转发地址
  location ^ ~ / bimg4 / {
    if ($request_uri~ / bimg4 / (. * )) {
      set $bucketid $1;
    }
    proxy_pass http: //$bucketid;
  }
}
