wordpress 6.5.5 出現ERR_TOO_MANY_REDIRECTS error

場景

1. 有對外IP充當反向代理程式VM(CentOS 7.9)
   httpd reverse proxy 2.4.6
2. 無對外IP，內部vm (RockyLinux 9.4)
   Docker CE + Container WordPress 6.5.5

讓反向代理程式連到wordpress，網頁測試居然出現ERR_TOO_MANY_REDIRECTS 錯誤

爬文之後，要在wordpress的wp-config.php加上

if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https') {
  $_SERVER['HTTPS'] = 'on';
}

再不行，要加上

if (isset($_SERVER['HTTP_X_FORWARDED_HOST']) && isset($_SERVER['HTTP_X_FORWARDED_PORT'])) {
  $_SERVER['HTTP_HOST'] = $_SERVER["HTTP_X_FORWARDED_HOST"];
  $_SERVER['SERVER_PORT'] = $_SERVER["HTTP_X_FORWARDED_PORT"];
}
