这是我至今在我的开发环境：

This is what I have so far in my development environment:

php_value error_log log/php.log
php_value display_errors 1
php_value magic_quotes_gpc Off

RewriteEngine On

# remove slash
RewriteCond %{REQUEST_FILENAME} !-d

# file.php to /file
RewriteCond %{THE_REQUEST} ^(.+).php([#?][^ ]*)? HTTP/
RewriteCond %{REQUEST_URI} !^/ajax.php
RewriteRule ^(.+).php$ http://localhost/$1 [R=301,L]

# /file to file.php
RewriteRule ^([^/.]+)$ $1.php [L]

我已经尝试了很多这条规则的变体，但我总是得到一个500错误：

I've tried a lot of variants of this rule but I always get a 500 error:

RewriteRule ^(.*)$ /book.php?url=$1 [L]

这是在我的Apache的error.log中：

And this is in my Apache's error.log:

[Fri Jul 27 19:56:51 2012] [error] [client 127.0.0.1] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

我在想什么，为什么重定向循环？

What am I missing, why the redirect loop?

推荐答案

您重写规则书面似乎试图做一个什么样的问题，标题是说相反。你说你想要 htaccess的重写/book.php?id=1234到/书/ 1234 ，但你的重写规则

Your RewriteRule as written appears to be trying to do opposite of what your question headline is saying. You say that you want htaccess rewrite /book.php?id=1234 to /book/1234, but your RewriteRule:

RewriteRule ^(.*)$ /book.php?url=$1 [L]

时添加查询字符串参数。

Is adding a query string parameter.

在下面的重写规则将改写重写/book.php?id=1234到/书/ 1234

The RewriteRule below will rewrite rewrite /book.php?id=1234 to /book/1234

RewriteCond %{QUERY_STRING} ^id=([0-9]*)$
RewriteRule ^book.php$ /book/%1? [L]

另外，如果你真的想要走另一条路，即重写 /电子书/ 1234 到 /book.php?id=1234 下面应该做的：

RewriteRule ^book/(.*)$ /book.php?id=$1 [L]
