URL重写未映前pression为参数 [英] Apache mod_rewrite not mapping expression to parameter

问题描述

我有一个网站，它使用 URL重写，并一直致力于为过去6个月，没有错误。

我有以下重写规则：

 重写规则^产品/（即[az \  - ] +）/ $ /products.php?category=$1 [NC，L]
 

下面是code。在我的网页 products.php

  $类别= $ _GET ['类'];

如果（使用isset（$类别））{
    //做一些处理这里
}
其他 {
    标题（位置：/500.html）;
    出口;
}
 

这打这个规则链接的一个例子是 /产品/照明灯杆/

有谁知道为什么实际的重写仍然存在，但不映射（即[az \ - ] +）到类= $ 1 ？

额外的信息

我注意到的.htaccess 主机上的文件已注释掉行选项+了FollowSymLinks 让我第一次试图重新启用此只为有现场返回一个Apache白色屏幕 500 错误。

更多来自.htaccess文件

 ＆LT; IfModule mod_rewrite.c＆GT;
#Options +的FollowSymLinks
RewriteEngine叙述上
的RewriteBase /

＃添加斜线为路径不带扩展名
的RewriteCond％{REQUEST_METHOD}！POST
的RewriteCond％{} REQUEST_FILENAME！-f
的RewriteCond％{REQUEST_URI}！（\ [A-ZA-Z0-9] {1,5} | /）$
重写规则^（。*）$ $ 1 / [L，R = 301]

＃其他规则，包括这里的问题规则

＆LT; / IfModule＆GT;
 

解决方案

这听起来病态像一个多视图的问题。多视图是内容协商东西在那里，如果它打开时，它会尝试在URL文件映射管道几个不同的额外的东西，试图找到映射到一个URL文件。在这里，你有一个像的URL /产品/等等，但是，你有一个名为 products.php ，所以多视图可以尝试映射产品到 /products.php/blah 。从而绕过重写规则完全，你看不到类参数。

当选项，试着加入：

 选项-Multiviews
 

I have a site which uses apache mod_rewrite and has been working for the last 6 months with no error.

I have the following rewrite rule:

RewriteRule ^products/([a-z\-]+)/$ /products.php?category=$1 [NC,L]

Here is the code in my page products.php

$category = $_GET['category'];

if (isset($category)) {
    // do some processing here
}
else {
    header("Location: /500.html");
    exit;
}

An example of a link which hits this rule is /products/lighting-poles/

Does anyone know why the actual rewrite is still occurring but not mapping the ([a-z\-]+) to category=$1?

Extra info

I noticed that the .htaccess file on the host has commented out the line Options +FollowSymLinks so I first tried to re-enable this only to have the site return an apache white screen 500 error.

More from the .htaccess file

<IfModule mod_rewrite.c>
#Options +FollowSymLinks
RewriteEngine On
RewriteBase /

# Add a trailing slash to paths without an extension
RewriteCond %{REQUEST_METHOD} !POST
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule ^(.*)$ $1/ [L,R=301]

# other rules including problem rule here

</IfModule>

解决方案

This sounds morbidly like a multiviews issue. Multiviews is a content-negotiation thing where if it's turned on, it'll try a few different extra things in the URL-file mapping pipeline to try to find a file that maps to a URL. Here you have a URL like /products/blah, yet, you have a file called products.php, so multiviews might try to map products to /products.php/blah. Thus bypassing the rewrite rule entirely, and you don't see the category parameter.

Where the options are, try adding:

Options -Multiviews
