如何修复apache2日志中的“找不到文件”错误

Question

我正在用PHP构建一个MVC框架。我正在使用像这样的分段URL：

http://mydomain.com/controller/method/param1/param2

我在Apache .htaccess中使用以下重写规则：

Options +FollowSymLinks
RewriteEngine on
RewriteRule ^([a-zA-Z\-_]*)/?([a-zA-Z]*)?/?([a-zA-Z0-9]*)?/?([a-zA-Z0-9]*)?/?$ index.php?controller=$1&method=$2&param1=$3&param2=$4 [NC,L]

URL工作正常，并且正在调用正确的控制器和方法。但是，我在apache2 error.log中遇到了很多错误。无论何时我访问具有两个或更多段的URL，我都会收到“找不到文件”错误。浏览器中没有404。

只是为了澄清，以下URL不会导致Apache日志中的错误。

http://dev.bonesphp.com/about

但是，以下URL将导致错误：

http://dev.bonesphp.com/about/test/pre>

文件不存在：/var/www/vhosts/dev.bonesphp.com/about

我的php.ini错误设置设置为E_ALL / STRICT

有谁知道如何解决这一问题？

提前致谢！

我在Apache中启用了重写日志。这是重写日志在我尝试访问上述URL时所说的内容：

Answer 1

我终于解决了这个！ “文件不存在”错误是由浏览器对favicon.ico的请求引起的！

当URL只有一个段，例如http://dev.bonesphp.com / about时，浏览器会从网站的根目录中请求favicon，这正是我的favicon所在的位置。但是，如果URL有两个段，例如http://dev.bonesphp.com / about / test，则浏览器从子目录请求它。在上述URL的情况下，它在http://dev.bonesphp.com/about中查找favicon。这导致404，因为没有名为'about'的目录（'/ about'映射到名为About.php的控制器文件）。

在Google上搜索后，我发现了一个Apache重写规则，适用于从任何目录请求的favicons：

http://perishablepress.com/redirect-all-requests-for-a-nonexistent-file-to-the-actual-file/

什么是PIA！我很高兴这已经结束了！
