php - 拉维尔 |错误: Header may not may not contain more than a single header

Question

我已经在我的 laravel 5.4 项目中实现了Multi-Auth，但是每当我尝试从其他设备登录时，我都会收到此错误。

ErrorException in Response.php line 386:Header may not contain more than a single header, new line detected

现在我尝试查看该网站中的其他类似问题，但没有一个与我在登录 Controller 中所做的相匹配。

这是我的登录 Controller :

   class LoginController extends Controller
{


    use AuthenticatesUsers;   

    public function __construct()
    {
        $this->middleware('guest', ['except' => 'logout']);
    }

    public function username()
    {
        return 'mobile_no';
    }

    protected function redirectTo( )
    {
        $notification = array(
            'message' => 'Welcome Admin!', 
            'alert_type' => 'info',
            'title' => Auth::user()->name
        );
        return redirect('/home')->with('notification', $notification);
    }
}

我的 redirecTo() 函数出了什么问题？

这个问题已经得到解答here 。 基本上你的方法应该返回一个字符串而不是重定向响应。 这是一个例子:

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
     /*
     |--------------------------------------------------------------------------
     | Login Controller
     |--------------------------------------------------------------------------
     |
     | This controller handles authenticating users for the application and
     | redirecting them to your home screen. The controller uses a trait
     | to conveniently provide its functionality to your applications.
     |
     */

     use AuthenticatesUsers;

     /**
      * Where to redirect users after login.
      *
      * @var string
      */
     //protected $redirectTo = '/';

     /**
      * Create a new controller instance.
      *
      * @return void
      */
     public function __construct()
     {
          $this->middleware('guest')->except('logout');
     }

     public function redirectTo(){
          return '/admin';
     }


}

但是因为您实际上需要重定向到 View 并包含一些对您不起作用的数据。您需要的是完全覆盖重定向功能并创建您自己的 . 这是您需要做的。您可以从这里复制整个类，它应该开箱即用:)。这是代码。干杯。

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
     /*
     |--------------------------------------------------------------------------
     | Login Controller
     |--------------------------------------------------------------------------
     |
     | This controller handles authenticating users for the application and
     | redirecting them to your home screen. The controller uses a trait
     | to conveniently provide its functionality to your applications.
     |
     */

     use AuthenticatesUsers;

     /**
      * Where to redirect users after login.
      *
      * @var string
      */
     //protected $redirectTo = '/';

     /**
      * Create a new controller instance.
      *
      * @return void
      */
     public function __construct()
     {
          //this should not be included
          //$this->middleware('guest')->except('logout');
     }

     //public function redirectTo(){
     //     return '/admin';
     //}
     protected function authenticated()
 {
      $notification = array(
          'message' => 'Welcome Admin!',
          'alert_type' => 'info',
          'title' => Auth::user()->name
      );
      return redirect('/home')->with('notification', $notification);
 }

}
