场景:订单下单成功之后 半小时之后如果没有付款 那么就把订单状态改为取消状态

可以使用laravel 的延时队列

修改 config/queue.php

'default' => env('QUEUE_CONNECTION', 'redis'),

使用redis的 有序集合

php artisan make:job DelayOrder 创建一个延时队列 就会在 app/Jobs目录下生成一个 DelayOrder.php 文件

<?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 Illuminate\Support\Facades\DB;
    class DelayOrder implements ShouldQueue
    {
        use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
        protected $id='';
        protected $redis='';
        protected  $key = 'order_list';
            /**
         * Create a new job instance.
         *
         * @return void
         */
        public function __construct($id)
        {
            $this->id = $id;
    
            $this->delay(300);
        }
    
        /**
         * Execute the job.
         *
         * @return void
         */
        public function handle()
        {
            //
            $results = DB::select('select * from orders where id = :id', [$this->id]);
    
            if($results[0]->status == 1){
                $affected = DB::update('update orders set status = 0 where id = ?', [$this->id]);
                if($affected){
                    var_dump('success');
                }
            }else{
               return;
            }
        }
    }

handle 方法 就是 设置时间后 如果到时间了 就会执行这个方法 改方法中可以写逻辑

那么如果调用这个延时队列呢

可以创建一个OrderController

<?php
    
    namespace App\Http\Controllers;
    
    use Illuminate\Http\Request;
    use Tymon\JWTAuth\Facades\JWTAuth;
    use Illuminate\Support\Facades\DB;
    use App\Jobs\DelayOrder;
    class OrderController extends Controller
    {
    
    
        protected  $redis = '';
        protected  $key = 'order_list';
    
        /**
         * Show the application dashboard.
         *
         * @return \Illuminate\Contracts\Support\Renderable
         */
        public function index()
        {
            $order_no = time();
            $goods_id = rand();
            $order = DB::insert('insert into orders ( order_no,goods_id) values (?, ?)', [$order_no, $goods_id]);
            $id = DB::getPdo()->lastInsertId();
    
            if($id){
                // 半小时之后 不付款 取消订单状态加入延时队列
                $this->dispatch(new DelayOrder($id));
            }else{
            }
        }
        
    }

在方法中  $this->dispatch  来分发这个job
