如何在Laravel的中间件中获取Route [英] How to get Route in Middleware in Laravel

问题描述

目前，我可以通过将其注入要使用的方法中来获得控制器中的路由.

Currently I can get a route in a controller by injecting it into the method I want to use it in.

<?php namespace App\Http\Controllers;

use Illuminate\Routing\Route;

class HomeController extends Controller
{
    public function getIndex(Route $route)
    {
        echo $route->getActionName();
    }
}

但是我试图在中间件中执行类似的操作，但无法继续进行.

However I'm trying to perform something similar in middleware but can't get it going.

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Routing\Route;
use Illuminate\Contracts\Routing\Middleware;

class SetView implements Middleware {

    protected $route;

    public function __construct(Route $route)
    {
        $this->route = $route;
    }

    public function handle($request, Closure $next)
    {
        echo $this->route->getActionName();

        return $next($request);
    }
}

遇到错误.

Unresolvable dependency resolving [Parameter #0 [ <required> $methods ]] in class Illuminate\Routing\Route

不太确定该怎么做.真的不在乎这是否是一条路线，但需要以某种方式获得该动作的名称.

Not really sure what to do with that. Don't really care if it's a route or not, but need to get that action name somehow.

推荐答案

删除构造函数/将其设置为默认值；

Remove your constructor/put it to default like;

public function __construct(){}

尝试通过handle方法访问路由；

Try accessing the route via the handle method like so;

 $request->route();

因此，您应该能够像这样访问动作名称；

So you should be able to access the action name like so;

 $request->route()->getActionName();

如果路线返回为空，请确保已在App/Http/Kernel.php中注册了中间件，就像这样；

If the route return is null be sure you have registered the middleware within the App/Http/Kernel.php, like so;

protected $middleware = [
    ...
    'Path\To\Middleware',
];

以上内容适用于全球中间件

对于特定于路由的过滤，将'Path\To\Middleware',放在App\Providers文件夹内RouteServiceProvider.php的中间件数组中.

For route specific filtering place the 'Path\To\Middleware', within the middleware array within RouteServiceProvider.php within the App\Providers folder.

您还可以通过app()->router->getCurrentRoute()访问路线对象.

You can also access the route object via app()->router->getCurrentRoute().

您可以尝试以下方法；

You could possibly try the following;

$route = Route::getRoutes()->match($request);
$route->getActionName();

这将从RouteCollection获取路线.确保将其封装在try catch中，因为这会抛出NotFoundHttpException.

This get the route from the RouteCollection. Be sure to encapsulate this within a try catch as this will throw a NotFoundHttpException.
