我正在尝试使用命令链式发送 3 封邮件withChain，所以基本上我发送第一封邮件，1 分钟后使用该delay()功能发送另一封邮件，1 分钟后再次发送第三封邮件。在文档中，他们谈论延迟和链接，但不是同时谈论它们中的两个。可能吗 ？

我收到一个错误：

函数 App\Jobs\SendEmail::__construct() 的参数太少，在第 139 行的 /home/vagrant/code/vendor/laravel/framework/src/Illuminate/Foundation/Bus/PendingChain.php 中传递了 0，而预期为 1

但我不知道为什么，因为我正在传递论点......

作业控制器.php

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Carbon\Carbon;
use App\Jobs\SendEmail;
use App\Http\Controllers\Controller;

class JobController extends Controller
{

/**
 *
 *
 * @param Request $request
 * @return \Illuminate\Http\RedirectResponse
 * @throws \Symfony\Component\HttpKernel\Exception\HttpException
 */
public function enqueue(Request $request)
{
     $details = ['email' => 'contact@uh-lawyers.fr'];
     SendEmail::withChain([
        new SendEmail($details),
        new SendEmail($details)
    ])->dispatch();
}

}

发送电子邮件.php：

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use App\Mail\NewUserNotification;
use Illuminate\Support\Facades\Mail;

class SendEmail implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $details;

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($details)
    {
        $this->details = $details;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $email = new NewUserNotification();
        Mail::to($this->details['email'])->send($email);
    }
}

新用户通知.php：

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class NewUserNotification extends Mailable
{
    use Queueable, SerializesModels;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->from('contact@uh-lawyers.fr', 'UH-Group')
            ->subject('Mailtrap Confirmation')
            ->markdown('mails.exmpl')
            ->with([
                'name' => 'New Mailtrap User',
                'link' => '/inboxes/'
            ]);
    }
}

谢谢。
