Question

我正在为我的网络应用创建自定义路由器。我使用MVC。

例如，当我输入fab.app/portfolio时，一切都很好。但是当我输入fab.app/portfolio/时，不显示css，图像和js。

这是因为路径改变了。在第一种情况下，它正在查找图像的路径是fab.app/images/(the_image)，但在第二种情况下，它是fab.app/portfolio/images/(the_image)。

另外，在index.php中，我必须有一个带有和不带斜杠的url的条目。我不喜欢。我宁愿不用斜杠写它也应该使用斜杠。

您可以在下面找到路由器和index.php

的index.php

<?php
require_once __DIR__ . '/../vendor/autoload.php';
require_once __DIR__ . '/../app/setup.php';

use Fab\Controllers;
use Fab\Router;

$router = new Router\Router();

$router->get('/', 'MainController', 'index');
$router->get('/portfolio', 'ItemsController', 'showAllItems');
$router->get('/portfolio/', 'ItemsController', 'showAllItems');
$router->get('/portfolio/[\w\d]+', 'ItemsController', 'single_item');
$router->get('/about', 'MainController', 'about');
$router->get('/contact', 'MainController', 'contact');
$router->get('/admin/dashboard', 'AdminController', 'index');
$router->get('/admin/dashboard/addItem', 'AdminController', 'addItem');
$router->get('/admin/dashboard/deleteItem', 'AdminController', 'deleteItem');
$router->get('/admin/dashboard/editItem', 'AdminController', 'editItem');
$router->get('/admin/dashboard/contactSupport', 'AdminController', 'contactSupport');

$router->post('/admin/addItem', 'AdminController', 'postAddItem');
$router->post('/admin/deleteItem', 'AdminController', 'postDeleteItem');
$router->post('/admin/editItem', 'AdminController', 'postEditItem');

//$router->get('/test', 'ItemsController', 'showAllItems');

////See inside $router
//echo "<pre>";
//print_r($router);

$router->submit();

的.htaccess

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    AddType 'text/css; charset=UTF-8' css

</IfModule>

在html

中调用css（以及图像和js）的示例

<link href="/css/my-admin-custom.css" rel="stylesheet">

为了清楚起见，这是我如何解决问题（按@ Max13＆＃39;答案）。这进入了Router.php：

        /**
         * If last char in URL is '/' redirect without it 
         * and also check if url is root '/' because this would result 
         * in infinite loop
         */
        if ( ($path[strlen($path)-1] === '/') && !($path === '/') ) { //
            $newPath = substr($path, 0, -1);
            header("Location: $newPath", true, 302);
            exit;
        }

Answer 1

使用和不使用斜杠并不意味着相同的目录级别，因此我不认为接受＆＃34;接受＆＃34;两者都在路由器中。

所以，一个好的解决方案恕我直言：在你的检查过程中，如果path以＆＃34; /＆＃34;结尾，则发送302 Found标题，不带斜杠。< / p>
