我正在尝试使用 httpauth 保护我的 wordpress 博客，但 RSS 提要除外。这在 apache 2.2 中对我有用，但我无法让它在 apache 2.4 中工作。

我的博客目录中有一个 .htaccess 文件，如下所示：

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>
# END WordPress

AuthUserFile .htpasswd
AuthGroupFile /dev/null
AuthName blog
AuthType Basic
SetEnvIf Request_URI ^.*/feed/$ allow_access
<RequireAny>
    Require env allow_access
    Require expr %{REQUEST_URI} =~ m#^.*/feed/$#
    Require ip 127.0.0.1
    Require valid-user
</RequireAny>

这确实要求我输入密码，这是应该的，但即使在以 /feed/ 结尾的 URI 上，它仍然会要求输入密码，这是不应该的。

我的理解是 RequireAny 块中的前两行中的任何一行都应该满足 RequireAny，因此不要求输入密码。

在 apache 2.2 这对我有用，与

allow from env=allow_access

我究竟做错了什么？有没有其他或更好的方法来做到这一点？

更新：我为 mod_rewrite 和 mod_authz 添加了额外的日志记录。这给了我以下信息：

所以授权检查两次；重写之前和之后。问题是，rewrite 后 request_uri 显然不一样了。欢迎提出建议。

我终于在这个Stack Exchange 问题中找到了答案

使用 url 重写时，环境变量保存为 REDIRECT_variable_name。

所以添加行

    Require env REDIRECT_allow_access

在<RequireAny>街区内为我解决了这个问题。
