带问号和&符的mod_rewrite(对于PHP) [英] mod_rewrite with question marks and ampersands (with PHP)

问题描述

我有一个基于PHP的Web应用程序，正在尝试将Apache的mod_rewrite应用到该应用程序.

I have a PHP-based web app that I'm trying to apply Apache's mod_rewrite to.

原始URL的格式为:
http://example.com/index.php?page=home&x= 5

Original URLs are of the form:
http://example.com/index.php?page=home&x=5

我想将它们转换为:
http://example.com/home?x=5

And I'd like to transform these into:
http://example.com/home?x=5

请注意，在重写页面名称时，我也有效地移动"了问号.当我尝试执行此操作时，Apache会愉快地执行以下翻译:

Note that while rewriting the page name, I'm also effectively "moving" the question mark. When I try to do this, Apache happily performs this translation:

RewriteRule ^/([a-z]+)\?(.+)$ /index.php?page=$1&$2  [NC,L]

但是它弄乱了PHP中的$_GET变量.例如，对http://example.com/home?x=88的调用仅产生一个$_GET变量(page => home). x => 88去哪里了?但是，当我更改规则以使用&"号而不是问号时:

But it messes up the $_GET variables in PHP. For example, a call to http://example.com/home?x=88 yields only one $_GET variable (page => home). Where did x => 88 go? However, when I change my rule to use an ampersand rather than a question mark:

RewriteRule ^/([a-z]+)&(.+)$ /index.php?page=$1&$2  [NC,L]

像http://example.com/home&x=88这样的调用将按我期望的那样工作(即page和x $ _GET变量均已适当设置).

a call like http://example.com/home&x=88 will work just as I'd expect it to (i.e. both the page and x $_GET variables are set appropriately).

我知道区别很小，但是如果可能的话，我希望我的URL变量以问号开始".我敢肯定，这反映了我对mod_rewrite重定向如何与PHP交互的误解，但看来我应该能够做到(一种或另一种方式).

The difference is minimal I know, but I'd like my URL variables to "start" with a question mark, if it's possible. I'm sure this reflects my own misunderstanding of how mod_rewrite redirects interact with PHP, but it seems like I should be able to do this (one way or another).

提前谢谢！

推荐答案

尝试一下:.

RewriteCond %{REQUEST_URI} !^/index.php
RewriteRule ^/([a-z]+)(?:$|\?(?:.+)) /index.php?page=$1 [NC,L,B,QSA,NE]

B转义了反向引用(由于它与[a-z] +匹配，因此没有必要，但是如果以后要扩展它，可能会很有用).

B escapes the backreference (shouldn't be necessary since it is matching [a-z]+, but in case you want to extend it later, it might be useful).

添加了RewriteCond. QSA负责添加&符.

added RewriteCond. EDIT 2: QSA takes care of adding the ampersand.
