apache2 仅通过 HTTP 响应“无效的主机头”

当我通过 HTTP 在 apache2 服务器上执行 cURL 请求时，我收到的唯一响应是Invalid Host header。但是，当使用 HTTPS 时，一切似乎都按预期工作。我确实为每个站点启用了重写以重定向到 HTTPS。这发生在所有子域中。虽然我做了一些挖掘，但我所能找到的都是与 webpack 相关的问题。

我正在apache2 2.4.52奔跑ubuntu 22.04 LTS。

这是我的主页的配置文件。

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/example.com
    ServerName example.com
    ServerAlias a.example.com
    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

输出cURL --head --verbose http://example.com

答案1

经过一番试验，我发现这是一个端口转发错误，因为它在本地解析正确，但在域中解析不正确。
