nginx跨域配置

主要是以下几行内容

        add_header Access-Control-Allow-Origin *;
        add_header Access-Control-Allow-Methods 'GET,POST,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';

        if ( $request_method = 'OPTIONS') {
             return 204;
        }

加在server里面

 如

    server {
        listen 80 ;

        server_name  localhost;
        access_log  logs/access.log  main;

        add_header Access-Control-Allow-Origin *;
        add_header Access-Control-Allow-Methods 'GET,POST,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';

        if ( $request_method = 'OPTIONS') {
             return 204;
        }

        location / {
            proxy_set_header Host $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
            proxy_pass http://1873;
            proxy_buffer_size  128k;
            proxy_buffers   32 32k;
            proxy_busy_buffers_size 128k;
            proxy_connect_timeout       60;
            proxy_send_timeout          60;
            proxy_read_timeout          60;
            send_timeout                60;

        }
    }
