nginx反向代理解决wechat图片问题

在nginx 中nginx.conf开启反向代理

   location ^~ /wechat_image/ {
             add_header 'Access-Control-Allow-Origin' "$http_origin" always;
             add_header 'Access-Control-Allow-Credentials' 'true' always;
             add_header 'Access-Control-Allow-Methods' 'GET, OPTIONS' always;
             add_header 'Access-Control-Allow-Headers' 'Accept,Authorization,Cache-Control,Content-Type,DNT,If-Mod    ified-  Since,Keep-Alive,Origin,User-Agent,X-Requested-With' always;
             proxy_pass http://thirdwx.qlogo.cn/;

             }

vhost下具体文件中的配置

然后重启nginx 即可；

location ^~ /wechat_image/ {
add_header 'Access-Control-Allow-Origin' "$http_origin" always;
add_header 'Access-Control-Allow-Credentials' 'true' always;
add_header 'Access-Control-Allow-Methods' 'GET, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Accept,Authorization,Cache-Control,Content-Type,DNT,If-Mod ified- Since,Keep-Alive,Origin,User-Agent,X-Requested-With' always;
proxy_pass http://thirdwx.qlogo.cn/;

}

会将该域名 http://thirdwx.qlogo.cn/ 替换成 自己的域名下的wechat_image/;从而解决跨域问题！
