wordpress - 反向代理的重定向太多

Question

设置:

• cloudflare DNS
• docker-compose
• nginx 反向代理
• wordpress
• nginx php 处理程序

问题

太多的重定向，就像在这些日志中:

nginx 反向代理自动创建它的配置，并将请求转发到 wp_web (IIRC)。

问题:

如何修复重定向循环？其他一切似乎都有效。我还有其他容器在运行，并且可以通过 domain2.com 访问，没有任何问题。

提前致谢；)

Answer 1

就像@Damocles 所说的那样，必须有

$_SERVER['HTTPS'] = 'on'; 在 wp-config.php 中。标准配置

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

好像还不够。
