如果的.htaccess URL不好做一些事情 [英] .htaccess if url is bad do something

问题描述

我正在做我个人的CMS。我想在这凉爽（型）的URL来使用。这是我的.htaccess文件code：

I'm making my personal CMS. I want to use in it cool (friendly) URLs. This is my .htaccess file code :

RewriteEngine on
RewriteBase /
DirectoryIndex index.php

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^([a-zA-Z-_0-9_/]+)/?$ index.php?args=$1 [L]

我看到，堆栈溢出也使用友好的URL。今天，我想对堆栈溢出做出错误。要（例如）这个网址 http://stackoverflow.com/questions/5469955/htaccess-url-rewrite-if-file-not-exists 我加了的.php 。但我没有看到404错误。我们在一个神奇的方法论坛删除了我的PostScript和重定向我回到正确的网站网址。我的问题是：如何才能让他同样在我的CMS ？我试图改变这种（重写规则^（[A-ZA-Z-_0-9 _ /] +）/ $的index.php？的args = $ 1 [L] ）行（重写规则^（[A-ZA-Z-_0-9 _ /] +）/（[A-ZA-Z-_0-9）$的index.php？的args = $ 1 [L] ），但是这是没有帮助的，然后我看到 500内部服务器错误。

I see that on Stack Overflow are also used friendly URLs. Today I tried to make error on Stack Overflow. To (for example) this URL http://stackoverflow.com/questions/5469955/htaccess-url-rewrite-if-file-not-exists I added .php. But I didn't seen 404 Error. Our forum in a magic method deleted my postscript and redirected me back to correct site URL. And my question is : How can I make he same in my CMS ? I tried to change this (RewriteRule ^([a-zA-Z-_0-9_/]+)/?$ index.php?args=$1 [L]) line to (RewriteRule ^([a-zA-Z-_0-9_/]+)/([a-zA-Z-_0-9)$ index.php?args=$1 [L]), but this isn't helpful and then I see 500 Internal Server Error.

推荐答案

如果你需要有像这样，那么你得有一些服务器端支持（例如PHP，ASP等），以及相同的行为。请考虑以下code片断：

If you need to have same behavior like SO then you got to have some server side support (e.g. PHP, ASP etc) as well. Consider following code snippet:

的.htaccess：

.htaccess:

RewriteRule ^([^/]+)/([^/]+)/?$ /index.php?id=$1&title=$2 [L,NC,QSA]

的index.php：

index.php:

<?php
   $id    = $_GET['id'];
   $title = $_GET['title'];

   $dbTitle = // get title from Database query using $id
   ...
   if ($title != $dbTitle) {
      // redirect with 301 to correct /<id>/<title> page
      header ('HTTP/1.1 301 Moved Permanently');
      header('Location: /' . $id . '/' . $dbTitle);
      exit;
   }
   // rest of your script
?>
