只需在nginx配置微信图片转发处理就好，加上如下代码：

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://wx.qlogo.cn/; }
