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
         }
