Question

我正在创建简单的推荐系统。我已经完成了工作，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
    ]);
}

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);
    }
}

我还在内核中添加了中间件

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，所有用户都获得了afflitiate_id，但没有一个获得数据库中的reference_by

编辑：整个控制器

<?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

我看到你的中间件不是问题。您需要更改控制器中cookie的获取方式：

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
    ]);
}

Answer 2

解决方案实际上非常简单。 \ App \ Http \ Middleware \ CheckReferral :: class，本来应该是$ middlewareGroups Web而不是$ middleware。这样应用程序就能捕获引用链接并将它们存储在cookie中。

Laravel新的中间件不起作用
