如何修复 Laravel 5.7 中的 "Class signed does not exist" 错误？

Question

我刚刚将我的 Laravel 项目从 5.6 更新到 5.7。我升级的主要原因是我需要将电子邮件验证添加到我的项目中。在我完成所有升级步骤并根据 Laravel 文档实施电子邮件验证后，我收到错误消息。所以导致错误的步骤是这样的：

我使用 1 条路径进行测试，在我的 ..\routes\web.php 文件中我有这行代码：

Route::get('dashboard', ['uses' => 'DashboardController@getDashboard'])->middleware('verified');

当我尝试去那条路线时，它确实将我重定向到 ..\views\auth\verify.blade.php 的视图。在那里我点击 link 发送验证邮件。我收到电子邮件，然后单击电子邮件中的按钮以验证我的电子邮件。它启动浏览器并开始导航我到某个地方，这就是它收到错误的时候：

Class signed does not exist

经过大量研究，我发现错误出在说明中说要创建的新 VerificationController.php 文件中，导致问题的代码行是：

$this->middleware('signed')->only('verify');

如果我注释掉这一行并再次单击我电子邮件中的按钮，那么它可以正常工作并且我的用户 email_verified_at 列会更新为日期时间戳。

下面是完整的VerificationController.pas，以防它能说明问题：

<?php

namespace App\Http\Controllers\Auth;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\VerifiesEmails;

class VerificationController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Email Verification Controller
    |--------------------------------------------------------------------------
    |
    | This controller is responsible for handling email verification for any
    | user that recently registered with the application. Emails may also
    | be re-sent if the user didn't receive the original email message.
    |
    */
    use VerifiesEmails;
    /**
     * Where to redirect users after verification.
     *
     * @var string
     */
    protected $redirectTo = '/dashboard';
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
        $this->middleware('signed')->only('verify');
        $this->middleware('throttle:6,1')->only('verify', 'resend');
    }
}

Answer 1

看看Laravel Documentation on Signed URLs

我猜你在 $routeMiddleware 数组

中遗漏了这个条目

// In app\Http\Kernel.php
/**
 * The application's route middleware.
 *
 * These middleware may be assigned to groups or used individually.
 *
 * @var array
 */
protected $routeMiddleware = [
    ...
    'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
];

我在 API 电子邮件验证方面遇到了同样的问题，我不得不添加触发电子邮件发送的事件 app/Providers/EventServiceProvider。php

protected $listen = [
    Registered::class => [
        SendEmailVerificationNotification::class,
    ],
];

并覆盖 app/Http/Controllers/Auth/VerificationController.php 函数

/**
 * Show the email verification notice.
 *
 */
public function show()
{

}

/**
 * Mark the authenticated user's email address as verified.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function verify(Request $request)
{
    if ($request->route('id') == $request->user()->getKey() &&
        $request->user()->markEmailAsVerified()) {
        event(new Verified($request->user()));
    }

    return response()->json('Email verified!');
}

/**
 * Resend the email verification notification.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function resend(Request $request)
{
    if ($request->user()->hasVerifiedEmail()) {
        return response()->json('User already have verified email!', 422);
    }

    $request->user()->sendEmailVerificationNotification();

    return response()->json('The notification has been resubmitted');
}

/**
 * Create a new controller instance.
 *
 * @return void
 */
public function __construct()
{
    $this->middleware('auth');
    $this->middleware('signed')->only('verify');
    $this->middleware('throttle:6,1')->only('verify', 'resend');
}
