"If"语句破坏了Rewrite*规则

wordpressapachemod-rewrite
7

我正在使用Apache/2.4.34的标准WordPress htaccess规则。如果我添加<If>语句，它会破坏重写功能。

# DEBUG is set to TRUE
<If "-T env('DEBUG')">
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</If>

除了根目录/之外，所有页面都返回：错误请求。您的浏览器发送了一个服务器无法理解的请求。

最后一个消息完全不可理解：add per-dir prefix: index.php -> *If/index.php 出了什么问题？

我有一个类似的案例，涉及到这些htaccess规则：

<If "%{REQUEST_URI} =~ m#^/resources/data/character/[0-9]{1,10}/(avatar|refsheet)\.png$#">
    # ... Other stuff here ...
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ resources/generic/default-refsheet.png
</If>

在这种情况下，当原始请求的文件不存在（并且匹配<If>中的正则表达式）时，请求将被重写为相对路径resources/generic/default-refsheet.png，导致愚蠢的*If/前缀被添加。
似乎Apache使用的目录前缀*If/是一个占位符，因为<If>的内容总是先应用，然后才能计算出实际的目录前缀。
在这种情况下，我找不到保持重写URL相对的方法，因此我使用了“绝对”（引号中的绝对是因为它实际上仍然相对于虚拟主机的DocumentRoot，但不是相对于htaccess所在的位置）。因此将规则更改为/resources/generic/default-refsheet.png（注意第一个位置的/）。
<If "%{REQUEST_URI} =~ m#^/resources/data/character/[0-9]{1,10}/(avatar|refsheet)\.png$#">
    # ...
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ /resources/generic/default-refsheet.png
</If>

在这种情况下，重写的URL不会以愚蠢的*If/目录前缀为前缀。
因此，对于您的问题，我建议在每个重写规则前面加上/（或/path/to/wordpress/from/document_root/）。
# DEBUG is set to TRUE
<If "-T env('DEBUG')">
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ /wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) /$1 [L]
RewriteRule ^(.*\.php)$ /$1 [L]
RewriteRule . /index.php [L]
</If>

但是，我仍然不确定它是否会起作用，也不确定为什么会起作用（因此我最初设置了悬赏）...

你可以将 If 语句改为

<If "env('DEBUG') == true">
