# Nsq
Nsq 是一个开源、轻量级、高性能的分布式消息中间件, 使用 go 语言实现
## 使用
### 配置
```
return [
'default' => [
'host' => '127.0.0.1',
'port' => 4150,
'pool' => [
'min_connections' => 1,
'max_connections' => 10,
'connect_timeout' => 10.0,
'wait_timeout' => 3.0,
'heartbeat' => -1,
'max_idle_time' => 60.0,
],
],
];
```
### 创建消费者
```
$ php bin/hyperf.php gen:nsq-consumer DemoConsumer
```
使用 `\Hyperf\Nsq\Annotation\Consumer` 注解可以是设置 `topic / channel / name / nums`, 使用 `$pool` 属性可以切换不同连接
```php
<?php
declare(strict_types=1);
namespace App\Nsq\Consumer;
use Hyperf\Nsq\AbstractConsumer;
use Hyperf\Nsq\Annotation\Consumer;
use Hyperf\Nsq\Message;
use Hyperf\Nsq\Result;
/**
* @Consumer(
* topic="hyperf",
* channel="hyperf",
* name ="TestNsqConsumer",
* nums=1
* )
*/
class TestNsqConsumer extends AbstractConsumer
{
public function consume(Message $payload): string
{
var_dump($payload->getBody());
return Result::ACK;
}
}
```
### 投递消息
使用 `\Hyperf\Nsq\Nsq::publish()` 投递消息, 同样可以使用 `$pool` 属性来切换不同连接
```php
<?php
declare(strict_types=1);
namespace App\Command;
use Hyperf\Command\Command as HyperfCommand;
use Hyperf\Command\Annotation\Command;
use Hyperf\Nsq\Nsq;
/**
* @Command
*/
class NsqCommand extends HyperfCommand
{
protected $name = 'nsq:pub';
public function handle()
{
/** @var Nsq $nsq */
$nsq = make(Nsq::class); // 可以设置 `$pool` 属性
$nsq->publish('hyperf', 'test'. time());
$this->line('nsq pub success', 'info');
}
}
```
