Laravel新的中间件不起作用

Question

我创建简单的转诊制度。我完成了这项工作，但推荐系统似乎无法正常工作，很可能是因为中间件。我会更清楚地解释这个问题。

所以，这里是我的注册控制器

protected function create(array $data) 
{ 
    $referred_by = Cookie::get('referral'); 

    return User::create([ 
     'name' => $data['name'], 
     'email' => $data['email'], 
     'password' => bcrypt($data['password']), 
     'affiliate_id' => str_random(10), 
     'referred_by' => $referred_by 
    ]); 
} 

而中间件

<?php 
namespace App\Http\Middleware; 

use Illuminate\Http\Response; 

use Closure; 

class CheckReferral 
{ 
/** 
* Handle an incoming request. 
* 
* @param \Illuminate\Http\Request $request 
* @param \Closure $next 
* @return mixed 
*/ 
public function handle($request, Closure $next) 
{ 
    if($request->hasCookie('referral')) { 
     return $next($request); 
    } 
    else { 
     if($request->query('ref')) { 
      return redirect($request->fullUrl())- 
    >withCookie(cookie('referral', $request->query('ref'), 30)); 
     } 
    } 
    return $next($request); 
    } 
} 

我还添加了中间件内核

protected $middleware = [ 
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class, 
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class, 
    \App\Http\Middleware\TrimStrings::class, 
    \App\Http\Middleware\CheckReferral::class, 
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class, 
]; 

因此，所有用户得到afflitiate_id，但其中没有一个在数据库中reference_by

编辑：整体REG控制器

<?php 

namespace App\Http\Controllers\Auth; 

use App\Http\Requests; 
use Illuminate\Http\Request; 
use DB; 
use App\User; 
use App\Http\Controllers\Controller; 
use Illuminate\Support\Facades\Validator; 
use Illuminate\Foundation\Auth\RegistersUsers; 
use Cookie; 

class RegisterController extends Controller 
{ 
/* 
|-------------------------------------------------------------------------- 
| Register Controller 
|-------------------------------------------------------------------------- 
| 
| This controller handles the registration of new users as well as their 
| validation and creation. By default this controller uses a trait to 
| provide this functionality without requiring any additional code. 
| 
*/ 

use RegistersUsers; 

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

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

/** 
* Get a validator for an incoming registration request. 
* 
* @param array $data 
* @return \Illuminate\Contracts\Validation\Validator 
*/ 
protected function validator(array $data) 
{ 
    return Validator::make($data, [ 
     'name' => 'required|string|max:255', 
     'email' => 'required|string|email|max:255|unique:users', 
     'password' => 'required|string|min:6|confirmed', 
    ]); 
} 

/** 
* Create a new user instance after a valid registration. 
* 
* @param array $data 
* @return \App\User 
*/ 
protected function create(array $data, Request $request) 
{ 
    $referred_by = $request->cookie('referral'); 

    return User::create([ 
     'name' => $data['name'], 
     'email' => $data['email'], 
     'password' => bcrypt($data['password']), 
     'affiliate_id' => str_random(10), 
     'referred_by' => $referred_by 
    ]); 
} 
} 

Answer 1

该解决方案实际上非常简单。 \ App \ Http \ Middleware \ CheckReferral :: class，应该已经到了$ middlewareGroups Web而不是$中间件。 因此，应用程序将能够捕获推介链接并将它们存储在cookie中。

Answer 2

我看你的中间件是没有问题的。您需要更改在控制器中获取Cookie的方式：

protected function create(array $data, Request $request) // Adding request as an argument. 
{ 
    $referred_by = $request->cookie('referral'); // Notice the change here 

    return User::create([ 
     'name' => $data['name'], 
     'email' => $data['email'], 
     'password' => bcrypt($data['password']), 
     'affiliate_id' => str_random(10), 
     'referred_by' => $referred_by 
    ]); 
}
