控制器

<?php

namespace App\Http\Controllers\User;

use App\Jobs\SendReminderEmail;
use App\User;
use Carbon\Carbon;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\DB;

class JobsController extends Controller
{
    //
    public function jobs()
    {
        $user = User::find(1);
        $this->dispatch((new SendReminderEmail($user))->delay(now()->addSeconds(30)));#延迟30秒
    }
}

队列文件

<?php

namespace App\Jobs;

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

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

    protected $user;

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

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        //
        Log::info('我是来自队列,发送了一个邮件', ['id' => $this->user->id, 'name' => $this->user->name]);
    }

    public function fail($exception = null)
    {

    }
}

我在控制器中设置了当请求过来的时候触发队列，我看delay好像应该是延迟，然后我设置的是30秒执行，为嘛当我请求玩了以后，立马去看日志马上就有数据被输出到laravel.log，而不是30秒后才被输出。用的数据库队列
