 location / {

            proxy_pass          http://web_servers; 
        proxy_redirect             off;
            proxy_set_header           Host             $host;
            proxy_set_header           X-Real-IP        $remote_addr;
            proxy_set_header           X-Forwarded-For  $proxy_add_x_forwarded_for;
        # 允许请求地址跨域 * 做为通配符
            add_header Access-Control-Allow-Origin * always;
            # 允许跨域的请求方法
            add_header Access-Control-Allow-Methods 'GET, POST, PUT, DELETE, OPTIONS';
            add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
        }
