在laravel中设置默认中间件

我是拉威尔框架的新手。我想设置一个中间件，它将在所有HTTP请求中调用。如何设置中间件？

使用全局中间件。发件人：

---

如果希望在应用程序的每个HTTP请求期间运行中间件，请在

app/HTTP/Kernel.php

类的

$middleware

属性中列出中间件类

---

如果希望中间件在应用程序的每个HTTP请求期间运行，请在app/HTTP/Kernel.php类的$middleware属性中列出中间件类，该类称为全局中间件

让我们举个例子

创建中间件

我们可以使用artisan轻松创建新的中间件

php artisan make:middleware AdMiddleware

在我们创建了一个新的中间件组件之后，我们需要考虑修改代码以满足我们的需要

正在更新我们的中间件文件：

运行make:middleware命令后，您应该可以在app/http/middleware中看到新的中间件文件。打开它，我们将创建一个中间件，它将获取请求的IP地址，然后确定该请求来自哪个国家

    <?php

namespace App\Http\Middleware;

use Closure;

class AdMiddleware {

    /** * Handle an incoming request. 
     * * * @param \Illuminate\Http\Request $request 
     * * @param \Closure $next * @return mixed */
    public function handle($request, Closure $next) { // Test to see if the requesters have an ip address. 
        if ($request->ip() == null) {
            throw new \Exception("IP ADDRESS NOT SET");
        } $country = file_get_contents('http://api.hostip.info/get_html.php?ip=' . $request->ip());
        echo $country;
        if (strpos($country, "UNITED STATES")) {
            throw new \Exception("NOT FOR YOUR EYES, NSA");
        } else {
            return redirect("index");
        } return $next($request);
    }

}

第二种选择是让中间件仅在注册的路由上运行，您可以这样注册它：

 <?php

    /** * The application's route middleware.
     *  * * @var array */
    protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'ad' => \App\Http\Middleware\AdMiddleware::class,
    ];

 <?php

    /** * The application's route middleware.
     *  * * @var array */
    protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'ad' => \App\Http\Middleware\AdMiddleware::class,
    ];

Route::get('/ip', ['middleware' => 'ad', function() { return "IP"; }]);
