我需要在中间件中找到当前找到的控制器和操作,以便我可以进行一些身份验证。但我发现这是不可能的,因为管道就像Middleware1 - > Middleware2->做调度 - > controller @ action() - > Middleware2 - > Middleware1。
因此在调度之前,我无法获得路线信息。在$ controller-> action()之后执行此操作绝对不对。
我做了一些研究并找到了这个。
$allRoutes = $this->app->getRoutes();
$method = \Request::getMethod();
$pathInfo = \Request::getPathInfo();
$currentRoute = $allRoutes[$method.$pathInfo]['action']['uses'];
但是在访问app/role/1
之类的URI时这不起作用,因为$allRoutes
只有app/role/{id}
而不是app/role/1
的索引。
有没有解决方法呢?

经过一番研究,我得到了解决方案。他们走了:
首先,你必须制作自己的自定义调度员,我的是:
App\Dispatcher\GroupCountBased
存储为:
app/Dispatcher/GroupCountBased.php
以下是GroupCountBased
:
<?php namespace App\Dispatcher;
use FastRoute\Dispatcher\GroupCountBased as BaseGroupCountBased;
class GroupCountBased extends BaseGroupCountBased
{
public $current;
protected function dispatchVariableRoute($routeData, $uri) {
foreach ($routeData as $data) {
if (!preg_match($data['regex'], $uri, $matches)) continue;
list($handler, $varNames) = $data['routeMap'][count($matches)];
$vars = [];
$i = 0;
foreach ($varNames as $varName) {
$vars[$varName] = $matches[++$i];
}
// HERE WE SET OUR CURRENT ROUTE INFORMATION
$this->current = [
'handler' => $handler,
'args' => $vars,
];
return [self::FOUND, $handler, $vars];
}
return [self::NOT_FOUND];
}
}
然后,通过singleton()
方法注册您自己的自定义调度程序。在之后注册所有路线!就我而言,我在bootstrap/app.php
之后添加了自定义调度程序:
require __DIR__.'/../app/Http/routes.php';
这就是它的样子:
/*
|--------------------------------------------------------------------------
| Load The Application Routes
|--------------------------------------------------------------------------
|
| Next we will include the routes file so that they can all be added to
| the application. This will provide all of the URLs the application
| can respond to, as well as the controllers that may handle them.
|
*/
require __DIR__.'/../app/Http/routes.php';
// REGISTER YOUR CUSTOM DISPATCHER IN LARAVEL CONTAINER VIA SINGLETON METHOD
$app->singleton('dispatcher', function () use ($app) {
return FastRoute\simpleDispatcher(function ($r) use ($app) {
foreach ($app->getRoutes() as $route) {
$r->addRoute($route['method'], $route['uri'], $route['action']);
}
}, [
'dispatcher' => 'App\\Dispatcher\\GroupCountBased',
]);
});
// SET YOUR CUSTOM DISPATCHER IN APPLICATION CONTEXT
$app->setDispatcher($app['dispatcher']);
注意:我知道它并不优雅,因为在执行中间件后调用
dispatch
,您必须手动调度您的调度程序。
在您的中间件中,在handle
方法中,执行以下操作:
app('dispatcher')->dispatch($request->getMethod(), $request->getPathInfo());
示例:
public function handle($request, Closure $next)
{
app('dispatcher')->dispatch($request->getMethod(), $request->getPathInfo());
dd(app('dispatcher')->current);
return $next($request);
}
获取当前路线:
app('dispatcher')->current;

我找到了这个问题的正确答案。我错过了一个名为routeMiddleware()
Application
的方法。此方法注册调度后调用的特定于路由的中间件。所以只需使用$app->routeMiddleware()
注册中间件即可。并在中间件中通过$request->route()
获取匹配的路由信息。

$methodName = $request->getMethod();
$pathInfo = $request->getPathInfo();
$route = app()->router->getRoutes()[$methodName . $pathInfo]['action']['uses'];
$classNameAndAction = class_basename($route);
$className = explode('@', $classNameAndAction)[0];
