如何调试 .htaccess RewriteRule 不起作用 [英] How to debug .htaccess RewriteRule not working

问题描述

我在 .htaccess 文件中有一个 RewriteRule 没有做任何事情.我该如何解决这个问题?

• 我如何验证 .htaccess 文件是否被 Apache 读取并遵守?我可以写一个回声它正在工作"的消息，如果我写了，那行会在哪里回显?
• 如果没有使用 .htaccess 文件，我如何让 Apache 使用它?
• 如果正在使用 .htaccess 但我的 RewriteRule 仍然没有效果，我还能做些什么来调试?

解决方案

在 .htaccess 中输入一些垃圾值例如foo bar, sakjnaskljdnashtaccess 无法识别的任何关键字并访问您的网址.如果它工作正常，你应该得到一个

500 内部服务器错误

内部服务器错误

服务器遇到内部错误或配置错误，无法完成您的请求....

我建议你在 RewriteEngine on 之后尽快把它.

<小时>

因为你在你的机器上.我想你可以访问 apache .conf 文件.

打开 .conf 文件，并查找类似于以下内容的行:

LoadModule rewrite_module modules/mod_rewrite.so

如果有注释(#)，取消注释并重启apache.

<小时>

日志重写

RewriteEngine OnRewriteLog "/path/to/rewrite.log"重写日志级别 9

将以上 3 行放在您的 virtualhost 中.重新启动httpd.

RewriteLogLevel 9 使用较高的 Level 值会显着降低 Apache 服务器的速度！使用级别大于 2 的重写日志文件仅用于调试！级别 9 将记录几乎所有 rewritelog 详细信息.

更新

Apache 2.4 发生了变化:

FROM 从 2.2 升级到 2.4

<块引用>

RewriteLog 和 RewriteLogLevel 指令已被删除.现在通过使用 LogLevel 指令为 mod_rewrite 模块配置适当的日志记录级别来提供此功能.另请参阅 mod_rewrite 日志记录部分.

有关 LogLevel 的更多信息，请参阅 LogLevel 指令

你可以做到

RewriteLog "/path/to/rewrite.log"

现在就这样

LogLevel 调试 rewrite_module:debug

I have a RewriteRule in a .htaccess file that isn't doing anything. How do I troubleshoot this?

• How can I verify if the .htaccess file is even being read and obeyed by Apache? Can I write an echo "it is working" message, if I do write it, where would that line be echoed out?
• If the .htaccess file isn't being used, how can I make Apache use it?
• If the .htaccess is being used but my RewriteRule still isn't having an effect, what more can I do to debug?

解决方案

Enter some junk value into your .htaccess e.g. foo bar, sakjnaskljdnas any keyword not recognized by htaccess and visit your URL. If it is working, you should get a

500 Internal Server Error

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request....

I suggest you to put it soon after RewriteEngine on.

Since you are on your machine. I presume you have access to apache .conf file.

open the .conf file, and look for a line similar to:

LoadModule rewrite_module modules/mod_rewrite.so

If it is commented(#), uncomment and restart apache.

To log rewrite

RewriteEngine On
RewriteLog "/path/to/rewrite.log"
RewriteLogLevel 9

Put the above 3 lines in your virtualhost. restart the httpd.

RewriteLogLevel 9 Using a high value for Level will slow down your Apache server dramatically! Use the rewriting logfile at a Level greater than 2 only for debugging! Level 9 will log almost every rewritelog detail.

UPDATE

Things have changed in Apache 2.4:

FROM Upgrading to 2.4 from 2.2

The RewriteLog and RewriteLogLevel directives have been removed. This functionality is now provided by configuring the appropriate level of logging for the mod_rewrite module using the LogLevel directive. See also the mod_rewrite logging section.

For more on LogLevel, refer LogLevel Directive

you can accomplish

RewriteLog "/path/to/rewrite.log"

in this manner now

LogLevel debug rewrite_module:debug
