定义队列

我们希望可以监听多个队列，所以便把队列名字额外定义出来。

<?php

declare(strict_types=1);

namespace app\constants;

class channel
{
    const queue = 'channel.queue';

    const test = 'channel.test';

    public static function getarray()

            self::queue,
            self::test,

}

　　

创建用于订阅的 redis 实例

 

更新配置

autoload/redis.php 中新增 subscriber 相关配置

<?php

declare(strict_types=1);
/**
 * this file is part of hyperf.
 *
 * @link     https://www.hyperf.io
 * @document https://doc.hyperf.io
 * @contact  [e-mail]
 * @license  https://github.com/hyperf-cloud/hyperf/blob/master/license
 */

return [
    'default' => [
        'host' => env('redis_host', 'localhost'),
        'auth' => env('redis_auth', null),
        'port' => (int) env('redis_port', 6379),
        'db' => (int) env('redis_db', 0),
        'pool' => [
            'min_connections' => 1,
            'max_connections' => 10,
            'connect_timeout' => 10.0,
            'wait_timeout' => 3.0,
            'heartbeat' => -1,
            'max_idle_time' => (float) env('redis_max_idle_time', 60),
        ],
    ],
    'subscriber' => [
        'host' => env('redis_host', 'localhost'),
        'auth' => env('redis_auth', null),
        'port' => (int) env('redis_port', 6379),
        'db' => (int) env('redis_db', 0),
        'options' => [
            \redis::opt_read_timeout => '-1',
        ],
        'pool' => [
            'min_connections' => 1,
            'max_connections' => 10,
            'connect_timeout' => 10.0,
            'wait_timeout' => 3.0,
            'heartbeat' => -1,
            'max_idle_time' => (float) env('redis_max_idle_time', 60),
        ],
    ],
];

　　

增加 subscriber 客户端

<?php
<?php

declare(strict_types=1);
/**
 * this file is part of hyperf.
 *
 * @link     https://www.hyperf.io
 * @document https://doc.hyperf.io
 * @contact  [e-mail]
 * @license  https://github.com/hyperf-cloud/hyperf/blob/master/license
 */

namespace app\process;

use app\constants\channel;
use app\kernel\subscriber;
use hyperf\process\abstractprocess;
use hyperf\process\annotation\process;

/**
 * @process(name="redisconsumerprocess")
 */
class redisconsumerprocess extends abstractprocess
{
    public function handle(): void
    {
        $redis = di()->get(subscriber::class);

        $redis->subscribe(channel::getarray(), function ($instance, $channelname, $message) {
            var_dump($instance);
            var_dump($channelname);
            var_dump($message);

            // todo: 执行对应的消费操作
        });
    }
}

　　

测试代码

修改 indexcontroller 如下

<?php

declare(strict_types=1);
/**
 * this file is part of hyperf.
 *
 * @link     https://www.hyperf.io
 * @document https://doc.hyperf.io
 * @contact  [e-mail]
 * @license  https://github.com/hyperf-cloud/hyperf/blob/master/license
 */

namespace app\controller;

use app\constants\channel;

class indexcontroller extends controller
{
    public function index()
    {
        $user = $this->request->input('user', 'hyperf');
        $method = $this->request->getmethod();

        $redis = di()->get(\redis::class);

        $redis->publish(channel::test, $user);

        return $this->response->success([
            'user' => $user,
            'method' => $method,
            'message' => 'hello hyperf.',
        ]);
    }
}

　　

启动 server，测试结果

$ curl http://127.0.0.1:9501/
{"code":0,"data":{"user":"hyperf","method":"get","message":"hello hyperf."}}

　　

终端显示如下

object(redis)#47173 (0) {
}
string(12) "channel.test"
string(6) "hyperf"

　　

未完待续
