【问题标题】:htaccess 301 redirect not workinghtaccess 301重定向不起作用
【发布时间】:2011-03-08 05:12:49
【问题描述】:

我正在尝试将简单的 301 规则添加到 codeigniter 站点的 .htaccess 文件中。

redirect 301 /newsletter http://sub.domain.com/newsletters/may2010

当我访问 http://sub.domain.com/newsletter 时,重定向会转到

http://sub.domain.com/newsletters/may2010/?/newsletter

我不确定 ?/newsletter 的来源。完整的 .htaccess 文件:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /    

    redirect 301 /newsletter http://sub.domain.com/newsletters/may2010

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>



<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    # Submitted by: ElliotHaughin

    ErrorDocument 404 /index.php
</IfModule>

我该如何解决这个问题?

    【解决方案1】:

    嘿,这是 Apache 对你使用了一个鬼鬼祟祟的处理顺序技巧。事实证明,您将Rewrite 命令放在文件顶部这一事实并不意味着它实际上是首先执行的。相反,mod_rewrite 首先运行,然后是 mod_alias(负责处理您的 Rewrite)。

    根据mod_rewrite,这将导致以下转换:

    newsletter --> index.php?/newsletter
    

    mod_rewrite 愉快地将查询字符串设置为?/newsletter,但是因为您没有指定PT 标志,所以 将重写的URL index.php 传递到mod_alias .因此,mod_alias 仍然看到/newsleter 路径,将其重定向到http://sub.domain.com/newsletters/may2010,并将(现已更改的)查询字符串?/newsletter 附加到末尾以完成交易。有趣的东西,对吧?

    无论如何,这种情况的快速解决方法是忽略对 newsletter 的请求:

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !newsletter$
    RewriteRule ^(.*)$ index.php?/$1 [L]
