namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Jobs\QueueTest;
use Illuminate\Support\Facades\Redis;
use Illuminate\Support\Facades\Queue;
use Illuminate\Support\Facades\DB;
use App\Jobs\InsertData;

class TestController extends Controller
{
    
    public function test()
    {
        dispatch(new InsertData($this->getQueueData()));
    }
    
    /**
     * return a array.
     * 
     * @return Array
     */
    private function getQueueData()
    {
        return 'user' . str_random(3);    
    }
}

已经创建了队列任务,为App/jobs/InsertData,上方是我的控制器。

接下来是我的队列文件:

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;
use Illuminate\Support\Facades\Redis;

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

    private $username;
    
    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($username)
    {
        $this->username = $username;
    }
    
    private function luckUserList($username)
    {
        $user = DB::table('user_list')->where('username', $username)->first();
        if (empty($user)) {
            $state = DB::table('user_list')->insert(array('username' => $username));
        }
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $data = DB::table('test')->find(1);
        $number = $data->num;
        if ($number > 0) {
            $this->luckUserList($this->username);
            --$number;
            DB::table('test')->where('id', 1)->update(array('num' => $number));
        } else {
            Redis::hset(
                array(
                    'user_list' => array($this->username)
                )
            );
        }
    }
}

接下来运行第一步,访问具体路由,也就是走到test方法中,laravel会将请求写入redis队列

使用AB工具

ab -n 1000 -c 500 http://laravel54.web/test

查看数量:

多次测试,结果应该是1000的,结果却不一致,难道我要用文件锁方式保证写入队列的一致性?这是第一步,就卡壳了,还没去执行队列,版本是laravel5.4,望兄弟帮忙看看,谢谢!

阿神

先确保真的能处理500并发请求,真的处理了1000个请求。

试试ab -n 1000 -c 1
