vue 调用nginx服务跨越的问题

    server {
        listen       80;
        server_name  api.xxxx.com;
        add_header Access-Control-Allow-Origin '*' ;
        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;
 
        location / {
            proxy_pass http://127.0.0.1:9001;
            proxy_connect_timeout 1600;
            proxy_read_timeout 6000;
 
        }
 
        location = /50x.html {
            root   html;
        }
    }

记得重新重启nginx， 有些nginx 会缓存配置，有点坑得很，我搞了很多都不行，最后关机，一天之后 nginx 自己把缓存给清
