PHP 8 - 找不到请求的路由 URL
PHP 8 - Routing can't find requested URL
我的 PHP 8 路由有问题。我正在创建我的 MVC“框架”以了解有关 OOP 的更多信息。我做了路由、控制器和视图 - 它有效,我很高兴。但是我发现我会测试我的创作。这就是问题开始的地方,即如果路径为空(“”),它 return 是路由中要求的“主页”视图,但是如果我在 URL,例如,我有一条 return 消息“404 未找到 - 在此服务器上未找到请求的 URL。”即使给定的路由已添加到 table。怎么了?

网络浏览器中的路由
我正在使用 XAMPP 与 PHP 8.0 和 Windows 10。
首先,选择以下两个选项之一继续。
选项 1:
如果文档根目录设置为与项目根目录相同,例如path/to/htdocs
,在web服务器的配置文件中(可能是httpd.conf
),类似这样:
DocumentRoot "/path/to/htdocs"
<Directory "/path/to/htdocs">
AllowOverride All
Require all granted
</Directory>
然后在 项目根目录 中创建以下 .htaccess
,从目录 path/to/htdocs/Public
中删除所有 .htaccess
文件并重新启动 Web 服务器:
<IfModule dir_module>
DirectoryIndex /Public/index.php /Public/index.html
</IfModule>
Options FollowSymLinks
RewriteEngine On
RewriteBase /Public/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php [QSA,L]
选项 2:
如果文档根目录设置为web服务器配置文件中的目录path/to/htdocs/Public
(可能是httpd.conf
),类似这样:
DocumentRoot "/path/to/htdocs/Public"
<Directory "/path/to/htdocs/Public">
AllowOverride All
Require all granted
</Directory>
然后在目录 path/to/htdocs/Public
中创建以下 .htaccess
,从 项目根目录 中删除任何其他 .htaccess
文件(除非它,也许,包含一些相关设置,而不是 DirectoryIndex
) 并重新启动网络服务器::
Options FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php [QSA,L]
在您决定并继续执行上述选项之一后,编辑页面 index.php
,如下所示:
<?php
//...
/*
* NOTE: A route pattern can not be an empty string.
* If only the host is given as URL address, the slash
* character (e.g. "/") will be set as value of the
* URI path, e.g. of $_SERVER['REQUEST_URI']. Therefore,
* the route pattern should be set to "/" as well.
*/
$routes->new('/', [
'controller' => 'HomeController',
'method' => 'index',
]);
//...
/*
* In order to get the URI path, you must use the server
* parameter "REQUEST_URI" instead of "QUERY_STRING".
*/
$routes->redirectToController(
$_SERVER['REQUEST_URI']
);
备注:
- 关于将
$_SERVER['QUERY_STRING']
更改为 $_SERVER['REQUEST_URI']
,当然要归功于@MagnusEriksson。
- 不能有“MVC 框架”,而是“基于 MVC 的应用程序的 Web 框架” .这是因为框架只是库的集合(与 MVC 完全无关),而这些库又被一个或多个实现 MVC 模式的应用程序使用。
