我的 .htaccess 文件中有一个 apache 代理服务器设置，其中包含以下内容
#Header always set Access-Control-Allow-Origin "*"
Header onsuccess unset Access-Control-Allow-Origin
Header always set Access-Control-Allow-Origin *
Header always set Access-Control-Max-Age "1000"
Header always set Access-Control-Allow-Headers "X-Requested-With, Content-Type, Origin, Authorization, Accept, Client-Security-Token, Accept-Encoding, x-api-token"
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L,E=HTTP_ORIGIN:%{HTTP:ORIGIN}]]
RewriteRule "^proxy/https/(.*)$" "https://$1" [P]
RewriteRule "^proxy/http/(.*)$" "http://$1" [P]
