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);
/**
* this file is part of hyperf.
*
* @link     https://www.hyperf.io
* @document https://doc.hyperf.io
* @contact  group@hyperf.io
* @license  https://github.com/hyperf-cloud/hyperf/blob/master/license
*/
namespace app\constants;
class channel
{
const queue = 'channel.queue';
const test = 'channel.test';
public static function getarray()
{
return [
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  group@hyperf.io
* @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  group@hyperf.io
* @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  group@hyperf.io
* @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
