nginx配置跨域

在nginx的server下面加上

 server {
        listen 443 ssl;
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Credentials' 'true';   
        add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,X-Requested-With';
        add_header 'Access-Control-Allow-Metthods' 'GET,POST,OPTIONS';
        location /live {
            flv_live on; #打开HTTP播放FLV直播流功能
            #https-flv on;

            chunked_transfer_encoding on; #支持'Transfer-Encoding: chunked'方式回复

或者

            add_header 'Access-Control-Allow-Origin' '*'; #添加额外的HTTP头
            add_header 'Access-Control-Allow-Credentials' 'true'; #添加额外的HTTP头
        }
