如何为apache2.4设置工作且安全的CORS配置？[重复]

Question

目前，我在apache2.4虚拟主机中有这个配置：

Header always append Access-Control-Allow-Origin "https://www.testdomain.local"
Header always append Access-Control-Allow-Origin "https://testdomain.local"
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
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"

RewriteEngine on

RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]

然而，我一直收到这个错误：

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.testdomain.local/ads?_=1572477483136. (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match ‘https://www.testdomain.local, https://testdomain.local’).

我知道我可以通过将访问控制允许原点设置为通配符来解决此问题，但这并不安全。

我能够通过使用此配置来解决它：

SetEnvIf Origin "http(s)?://(.+\.)?testdomain\.local$" CORS=$0
Header always set Access-Control-Allow-Origin "%{CORS}e" env=CORS
Header always merge Vary "Origin"
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS"
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"

RewriteEngine on

RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule ^(.*)$ $1 [R=200,L]
