.htaccess 重写条件
此规则在 .htaccess 文件中工作得很好：
ErrorDocument 403 /AccessDenied.html
ErrorDocument 404 /NotFound.html
RewriteEngine on
RewriteBase /
RewriteRule ^(index(\.(html|htm))?)$ / [R]
作为条件编写的相同规则不起作用：
ErrorDocument 403 /AccessDenied.html
ErrorDocument 404 /NotFound.html
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_URI} ^(index(\.(html|htm))?)$
RewriteRule ^(index(\.(html|htm))?)$ / [R]
我想我的问题是为什么该规则在第一个场景中有效，但在第二个场景中不起作用？我该如何解决它？
This rule works just fine in a .htaccess file:
ErrorDocument 403 /AccessDenied.html
ErrorDocument 404 /NotFound.html
RewriteEngine on
RewriteBase /
RewriteRule ^(index(\.(html|htm))?)$ / [R]
The same rule written as a conditional doesn't work:
ErrorDocument 403 /AccessDenied.html
ErrorDocument 404 /NotFound.html
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_URI} ^(index(\.(html|htm))?)$
RewriteRule ^(index(\.(html|htm))?)$ / [R]
I suppose my question is that why is the rule working in the first scenario, but not in the second? And how can I fix it?

我相信您的问题是
RewriteBase处理（始终删除前导斜杠）不会影响%{REQUEST_URI}等变量，并且不适用于无论如何，RewriteCond 都会进行处理。因此，模式
^(index(\.(html|htm))?)$在RewriteRule中可以正常工作，但在RewriteCond中则不行> 根据请求 URI 进行匹配。您需要包含前导斜杠（至少如果您使用开头^锚点）：I believe your problem is that the
RewriteBaseprocessing (which always strips the leading slash) doesn't affect variables like%{REQUEST_URI}and doesn't apply forRewriteCondprocessing anyway.So, the pattern
^(index(\.(html|htm))?)$will work fine in aRewriteRule, but not aRewriteCondmatching against the request URI. You need to include that leading slash (at least if you're using the beginning^anchor):
