Question

我使用Laravel 5.

我试试，

 "use Illuminate\Contracts\Routing\Middleware;"

将“中间件”实现为，

class Language implements Middleware {
       // Some Functions 
  }

我得到错误，

Interface 'Illuminate\Contracts\Routing\Middleware' not found

实际上该界面是否缺失？

（或）错误定义？

（或）需要创建|下载？

谢谢Q！

Answer 1

Illuminate \ Contracts \ Routing \ Middleware合约已在5.2中弃用，请将其删除。并且不要在课堂定义中使用它。

喜欢这个

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Routing\Redirector;
use Illuminate\Http\Request;
use Illuminate\Foundation\Applicaion;

class Language{
    //..... YOUR CODE
}

Answer 2

我不知道你是否真的放了那些双引号，但这是一个有效的例子：

<?php

use Illuminate\Contracts\Routing\Middleware;

class Language implements Middleware {
   // Some Functions 
}

Answer 3

我的班级：

命名空间App \ Http \ Middleware;

use Closure;

use Illuminate\Routing\Redirector;
use Illuminate\Http\Request;
use Illuminate\Foundation\Application;
use Illuminate\Contracts\Routing\Middleware;

class Language implements Middleware {

public function __construct(Application $app, Redirector $redirector, Request $request) {
    $this->app = $app;
    $this->redirector = $redirector;
    $this->request = $request;
}

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Closure  $next
 * @return mixed
 */
public function handle(Closure $next, $request)
{
    // Make sure current locale exists.
    $locale = $request->segment(1);

    if ( ! array_key_exists($locale, $this->app->config->get('app.locales'))) {
        $segments = $request->segments();
        $segments[0] = $this->app->config->get('app.fallback_locale');

        return $this->redirector->to(implode('/', $segments));
    }

    $this->app->setLocale($locale);

    return $next($request);
}

 }
