使用htaccess将所有重定向到index.php [英] Redirect all to index.php using htaccess
问题描述
我正在编写一个简单的基于PHP的MVC-ish框架.我希望该框架能够安装在任何目录中.
I'm writing a simple PHP-based MVC-ish framework. I want this framework to be able to be installed in any directory.
我的PHP脚本获取了请求uri并将其分成多个部分.它使段1成为控制器，而段2成为动作.当我这样做时，一切都很好:
My PHP script grabs the request uri and breaks it off into segments. It makes segment 1 the controller and segment 2 the action. This goes all fine when I do this:
http://www.example.com/mvc/module/test/
它将转到特定的模块控制器和方法.现在，我有一个默认控制器，即home控制器，它位于文件夹home中.
It will go to the specific module controller and method. Now I have a default controller, the home controller, which is in folder home.
现在，当我直接访问此文件夹时 http://www.example.com/mvc/home/ 它将显示403禁止，因为此文件夹确实存在，相反，它还应返回到 http://www.example.com/mvc/index.php
Now when I access this folder directly http://www.example.com/mvc/home/ It will display a 403 forbidden, because this folder does exist, instead it should also go back to http://www.example.com/mvc/index.php
If I would have installed the framework in a different folder, lets say folder framework it has to redirect back to http://www.example.com/framework/index.php
我想将每个文件夹和php文件重定向回index.php，而其他都保持原样.
I would like to redirect every folder and php file back to the index.php, leaving everything else the way it is.
我遇到的第一个问题是它从未重定向到正确的文件夹，始终重定向到域根文件夹.
My first problem I encountered was it never redirects to the right folder, always to the domain root folder.
这是我尝试过的:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.php [L]
推荐答案
您的重写规则看起来几乎可以.
Your rewrite rule looks almost ok.
首先请确保您的.htaccess文件位于文档根目录(与index.php相同的位置)中，否则只会影响其所在的子文件夹(及其中的所有子文件夹-递归).
First make sure that your .htaccess file is in your document root (the same place as index.php) or it'll only affect the sub-folder it's in (and any sub-folders within that - recursively).
下一步，对您的规则进行一些更改，使其类似于:
Next make a slight change to your rule so it looks something like:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]
目前，您只在.上进行匹配，这是任何字符的一个实例，您至少需要.*才能匹配任何数量的任何字符的实例.
At the moment you're just matching on . which is one instance of any character, you need at least .* to match any number of instances of any character.
$_GET['path']变量将包含伪造的目录结构，例如/mvc/module/test，您可以在index.php中使用它来确定 Controller 和要执行的操作.
The $_GET['path'] variable will contain the fake directory structure, so /mvc/module/test for instance, which you can then use in index.php to determine the Controller and actions you want to perform.
如果要将整个shebang安装在子目录(例如/mvc/或/framework/)中，最简单的方法是略微更改重写规则以将其考虑在内.
If you want the whole shebang installed in a sub-directory, such as /mvc/ or /framework/ the least complicated way to do it is to change the rewrite rule slightly to take that into account.
RewriteRule ^(.*)$ /mvc/index.php?path=$1 [NC,L,QSA]
并确保index.php位于该文件夹中，而.htaccess文件位于文档根目录中.
And ensure that your index.php is in that folder whilst the .htaccess file is in the document root.
替代$_GET['path'] (已于18年2月和19年1月更新)
Alternative to $_GET['path'] (updated Feb '18 and Jan '19)
实际上没有必要(甚至现在也不常见)将 path 设置为$_GET变量，许多框架都将依赖$_SERVER['REQUEST_URI']来检索相同的信息-通常可以确定哪个 Controller 可以使用-但原理完全相同.
It's not actually necessary (nor even common now) to set the path as a $_GET variable, many frameworks will rely on $_SERVER['REQUEST_URI'] to retrieve the same information - normally to determine which Controller to use - but the principle is exactly the same.
这确实简化了RewriteRule，因为您无需创建 path 参数(这意味着OP的原始RewriteRule 现在将开始工作):
This does simplify the RewriteRule slightly as you don't need to create the path parameter (which means the OP's original RewriteRule will now work):
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L,QSA]
但是，关于在子目录中安装的规则仍然适用，例如
However, the rule about installing in a sub-directory still applies, e.g.
RewriteRule ^.*$ /mvc/index.php [L,QSA]
标志:
NC =不区分大小写(不区分大小写，因为该模式中没有字符，所以没有必要)
NC = No Case (not case sensitive, not really necessary since there are no characters in the pattern)
L = Last(在此Rewrite之后它将停止重写，因此请确保它是您重写列表中的最后一件事)
L = Last (it'll stop rewriting at after this Rewrite so make sure it's the last thing in your list of rewrites)
QSA =附加查询字符串，以防万一您想保留诸如?like=penguins之类的东西并传递给index.php.
QSA = Query String Append, just in case you've got something like ?like=penguins on the end which you want to keep and pass to index.php.
