Consul 协程客户端

Hyperf 提供了一个 Consul 的协程客户端，由于 Consul 本身的 API 比较简单，也支持 HTTP 的请求方法，故该组件仅对 API 进行了一些封装上的简化，基于 hyperf/guzzle 提供的协程 HTTP 客户端支持。

ConsulResponse 类指的是 Hyperf\Consul\ConsulResponse 类

安装

composer require hyperf/consul

使用

• 获取对应 Consul 客户端，下面以 KV 客户端为例：

use Hyperf\Consul\KV;
use Hyperf\Guzzle\ClientFactory;
use Hyperf\Utils\ApplicationContext;

$container = ApplicationContext::getContainer();
$clientFactory = $container->get(ClientFactory::class);

$consulServer = 'http://127.0.0.1:8500';
$kv = new KV(function () use ($clientFactory, $consulServer) {
    return $clientFactory->create([
        'base_uri' => $consulServer,
    ]);
});

Consul ACL Token

通过 Header 添加 Token

您可在调用方法时往 Client 传递 Key 为 X-Consul-Token 的 Header 来设置，如下所示：

use Hyperf\Consul\KV;
use Hyperf\Guzzle\ClientFactory;
use Hyperf\Utils\ApplicationContext;

$container = ApplicationContext::getContainer();
$clientFactory = $container->get(ClientFactory::class);

$consulServer = 'http://127.0.0.1:8500';
$kv = new KV(function () use ($clientFactory, $consulServer) {
    return $clientFactory->create([
        'base_uri' => $consulServer,
        'headers' => [
            'X-Consul-Token' => 'your-token'
        ],
    ]);
});

通过 Query 添加 Token

您也可在调用方法时往 $options 参数传递 Key 为 token 的参数来设置，这样 Token 会跟随 Query 一起传递到 Server，如下所示：

$response = $kv->get($namespace, ['token' => 'your-token'])->json();
