今天折腾halo的时候，发现artalk出现跨域访问报错，内容如下。
Access to fetch at 'https://artk.musnow.top/api/stat' from origin 'https://halo.musnow.top' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values ', https://halo.musnow.top', but only one is allowed.
Have the server send the header with a valid value, or, if an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
尝试在nginx里面加了一个跨域访问头，依旧没有解决这个问题
add_header Access-Control-Allow-Origin 'https://halo.musnow.top' always;
后来咨询其他老哥才知道，这是artalk内部可信域名配置的问题，不需要修改nginx配置文件。(记得把上方的nginx配置删掉)
我只添加了站点的可信域名，artalk系统设置里面还有一个可信域名配置
设置了之后需要重启artalk容器，才能让修改生效
docker restart artalk-go
现在就OK了
