我有两个项目，想通过反向代理转发访问

    server {
       listen  80;
       server_name www.code.com;

location / {
     proxy_set_header Host $http_host;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Fonwarded-For $proxy_add_x_forwarded_for;
     proxy_pass http://172.16.65.69:8085;
#    访问：http://www.code.com/erp-glxt/ 可以正常转发
   }


     location /login {
                index  index.html index.htm;
                proxy_buffering off;
#                proxy_pass   http://zhfwweb;
                proxy_pass   http://172.16.93.188:9995/;
#    访问：http://www.code.com/login   资源404       }
     location /code/ {
        root /var/www/html/cm5;
                proxy_set_header Host  $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                add_header backendIP $upstream_addr;
                add_header 'Access-Control-Allow-Origin' '*';
                proxy_connect_timeout 600;
                proxy_send_timeout 600;
                proxy_read_timeout 600;
                proxy_pass http://172.16.65.69:8183/;

      }
