Laravel 5 类App\Http\Controllers\API\UserController不存在

我有一个问题，就是邮递员没有收到代币，还有下面的问题

反射异常 …\vendor\laravel\framework\src\illumb\Container\Container.php790 用户控制器不存在

如何解决此问题？

如果控制器路径为

/App/Http/Controllers/API

，则需要调整其命名空间：

namespace-App\Http\Controllers\API；

如果控制器路径为

/App/Http/Controllers

，则需要调整路由：

Route:：post（'login'，'UserController@login');

只需在名称空间中编写文件夹扩展即可

比如你的情况

namespace-App\Http\Controllers\API

在途中，你只需写

Route:：post（'register'，'api\UserController@register');
这可能是因为您没有在指向该控制器的用户路由上调用正确的中间件。您必须创建一个用户中间件

您可以通过导航到App\Http\Middleware并添加名为UserMiddleware.php的用户中间件和一些代码来实现这一点

首先，您需要导入以下文件

namespace App\Http\Middleware;

use Closure;

use Illuminate\Support\Facades\Auth;


然后创建一个名为<代码>类用户中间件

像这样给它添加一个句柄函数<代码>公共功能句柄（$request，Closure$next）

在该函数中包含以下代码

if (Auth::user()->usertype == 'user')
{
    return $next($request);
}

接下来，转到App\Http\Kernel.php，在受保护的$routeMiddleware部分的底部添加以下代码

        'user' => \App\Http\Middleware\UserMiddleware::class,

然后转到路由（API），并将此预定义的用户中间件包含到URL中

Route::group(['middleware' => 'user'], function () {

   Route::post('login', 'API\UserController@login'); 
   Route::post('register', 'API\UserController@register');
   Route::post('details', 'API\UserController@details'); 

});

}))

要使其工作，您需要在用户表中有一个默认设置为

user

的

usertype

字段。您的usertype列应该如下所示

    $table->string('usertype')->nullable()->default('user');

---

1。复制控制器的现有功能并将其删除

2。重新创建控制器，但这次在控制器目录中指定要放置它的位置。e、 g

php artisan make:YourSubfolder的控制器名称\YourControllersName

---

3。粘贴您的函数。

请注意，在您提供的代码中，路由指向“App\Http\Controllers\API\UserController”，但您的控制器定义在“App\Http\Controllers”命名空间中：-）
