.htaccess 网址 使用mod_rewrite重写文件扩展名和前端控制器

Question

我目前有一个文件正在从URL中删除.php，以使其整洁，更适合SEO。

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.php [NC,L]

我有一个名为Main.php的页面，我使用Main.php?Page=page1.php显示其他页面。我想向我的.htaccess文件添加一个规则，该规则仍允许我删除.php规则并使Main.php?Page=page1.php显示为

URL.com/page1

这可能吗？当我将以下行添加到我的文件中时，我的主页开始循环加载，当我删除该行时，它工作正常。

RewriteRule ^(.*)$ Main.php?Page=$1.php [QSA,L]

我是否写错了这一行并导致它循环？

Answer 1

RewriteRule ^(.*)$ Main.php?Page=$1.php [QSA,L]

在重写 URL 之前，您需要确保尚未Main.php。这就是导致循环的电流...Main.php?Page=Main.php.php&Page=Main....等

尝试类似操作：

# (1) If requesting a ".php" file (including "Main.php")
# or any known static resource then stop here...
RewriteRule .(php|css|js|jpe?g|png|gif)$ - [L]
# (3) Otherwise, if the request doesn't map to an existing file then rewrite to Main.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) Main.php?Page=$1.php [QSA,L]

如果不在原始请求上传递查询字符串，请删除QSA标志。

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.php [NC,L]

您之前附加.php扩展的指令应该检查附加.php是否会导致有效的请求，否则这将.php附加到所有非 php 请求并且永远不会达到Main.php。像这样：

# (2) Append ".php" if there is no extension
# but only if appending ".php" would result in a valid request
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^([^.]+)$ $1.php [L]

无需在字符类中转义点。这里不需要NC标志。

总结：因此，将

这些因素结合在一起，我们有：

# (1) If requesting a ".php" file (including "Main.php")
# or any known static resource then stop here...
RewriteRule .(php|css|js|jpe?g|png|gif)$ - [L]
# (2) Append ".php" if there is no extension
# but only if appending ".php" would result in a valid request
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^([^.]+)$ $1.php [L]
# (3) Otherwise, if the request doesn't map to an existing file then rewrite to Main.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) Main.php?Page=$1.php [QSA,L]

更新#2：仅将.php附加到Login，index和Signup，而不是任何存在的文件。其他所有内容(包括不存在的文件)都将重写为Main.php.

# (2) Append ".php" to select requests
# but only if appending ".php" would result in a valid request
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^(Login|index|Signup)$ $1.php [L]
# (3) Otherwise, rewrite everything else to Main.php
RewriteRule (.*) Main.php?Page=$1.php [QSA,L]
