HTTP 到 HTTPS 重定向在 WordPress 的 Apache+Varnish 中不起作用

Question

我面临的问题是 http 到 https 重定向不起作用。我目前的设置是清漆+apache。我正在使用 apache 来终止 SSL。按照本指南 (https://bash-prompt.net/guides/apache-varnish/) 执行此操作（还按照该指南中的“ERR_TOO_MANY_REDIRECTS 错误”部分，因为我收到了太多重定向错误）。 Varnish 在端口 80 上运行。Apache 在端口 8181 上运行并终止 SSL。尝试在 htaccess 中添加重定向规则，但它不起作用。在 wp-config 中添加了以下几行

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

if ( !isset( $_SERVER['HTTPS'] ) ) {
    $_SERVER['HTTPS'] = 'on';
}
define( 'WP_HOME', 'https://example.com' );
define( 'WP_SITEURL', 'https://example.com' );

我当前的 varnish vcl 配置：

vcl 4.0;

# Default backend definition. Set this to point to your content server.
backend default {
    .host = "127.0.0.1";
    .port = "8181";
}

sub vcl_recv {

if (req.url ~ "wp-admin|wp-login") {

return (pass);

}

sub vcl_backend_response {
    # Happens after we have read the response headers from the backend.
    #
    # Here you clean the response headers, removing silly Set-Cookie headers
    # and other mistakes your backend does.
}

sub vcl_deliver {
    # Happens when we have all the pieces we need, and are about to send the
    # response to the client.
    #
    # You can do accounting or modifying the final object here.
}

我的 htaccess 配置：

SetEnvIf X-Forwarded-Proto "https" HTTPS=on
Header append Vary: X-Forwarded-Proto

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP:X-Forwarded-Proto} !https [NC]
  RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

我几乎尝试了所有教程。甚至尝试通过 varnish vcl 配置本身将 HTTP 重定向到 HTTPS，但似乎没有任何效果。请帮忙！

将所有用户从 HTTP 重定向到 HTTPS

您可以使用以下任何解决方案。您只需要使用其中的一个或全部三个，由您自己决定。

1. PHP解决方案

if(!isset($_SERVER['HTTPS']) || strtolower($_SERVER['HTTPS']) != 'on') {
    header('Location: https://www.yourdomain.com');
    exit;
}

2。 Apache .htaccess 解决方案

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.yourdomain.com/$1 [R,L]

3. Nginx 解决方案

server {
    listen 80 default_server;
    server_name _;
    return 301 https://$host$request_uri;
}

Answer 2

对于另一个 php 解决方案，您也可以在 public/index.php 的开头使用它 这在你的情况下应该更有效

if($_SERVER['SERVER_PORT'] != 443) {
    header('Location: https://www.yourdomain.com');
    exit;
}

echo 'Your current server port is = '.$_SERVER['SERVER_PORT'].'<br />';
