基於多路複用的 RPC 組件
本組件基於 TCP
協議,多路複用的設計借鑑於 AMQP
組件。
安裝
composer require hyperf/rpc-multiplex
Server 配置
修改 config/autoload/server.php
配置文件,以下配置刪除了不相干的配置。
settings
設置中,分包規則不允許修改,只可以修改 package_max_length
,此配置需要 Server
和 Client
保持一致。
<?php
declare(strict_types=1);
use Hyperf\Server\Event;
use Hyperf\Server\Server;
return [
'servers' => [
[
'name' => 'rpc',
'type' => Server::SERVER_BASE,
'host' => '0.0.0.0',
'port' => 9502,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
Event::ON_RECEIVE => [Hyperf\RpcMultiplex\TcpServer::class, 'onReceive'],
],
'settings' => [
'open_length_check' => true,
'package_length_type' => 'N',
'package_length_offset' => 0,
'package_body_offset' => 4,
'package_max_length' => 1024 * 1024 * 2,
],
'options' => [
// 多路複用下,避免跨協程 Socket 跨協程多寫報錯
'send_channel_capacity' => 65535,
],
],
],
];
創建 RpcService
<?php
namespace App\RPC;
use App\JsonRpc\CalculatorServiceInterface;
use Hyperf\RpcMultiplex\Constant;
use Hyperf\RpcServer\Annotation\RpcService;
#[RpcService(name: "CalculatorService", server: "rpc", protocol: Constant::PROTOCOL_DEFAULT)]
class CalculatorService implements CalculatorServiceInterface
{
}
客户端配置
修改 config/autoload/services.php
配置文件
<?php
declare(strict_types=1);
return [
'consumers' => [
[
'name' => 'CalculatorService',
'service' => App\JsonRpc\CalculatorServiceInterface::class,
'id' => App\JsonRpc\CalculatorServiceInterface::class,
'protocol' => Hyperf\RpcMultiplex\Constant::PROTOCOL_DEFAULT,
'load_balancer' => 'random',
// 這個消費者要從哪個服務中心獲取節點信息,如不配置則不會從服務中心獲取節點信息
'registry' => [
'protocol' => 'consul',
'address' => 'http://127.0.0.1:8500',
],
'nodes' => [
['host' => '127.0.0.1', 'port' => 9502],
],
'options' => [
'connect_timeout' => 5.0,
'recv_timeout' => 5.0,
'settings' => [
// 包體最大值,若小於 Server 返回的數據大小,則會拋出異常,故儘量控制包體大小
'package_max_length' => 1024 * 1024 * 2,
],
// 重試次數,默認值為 2
'retry_count' => 2,
// 重試間隔,毫秒
'retry_interval' => 100,
// 多路複用客户端數量
'client_count' => 4,
// 心跳間隔 非 numeric 表示不開啓心跳
'heartbeat' => 30,
],
],
],
];
註冊中心
如果需要使用註冊中心,則需要手動添加以下監聽器
<?php
return [
Hyperf\RpcMultiplex\Listener\RegisterServiceListener::class,
];
使用
- 定義接口
比如我們需要設計一個發送短信的 RPC 服務
<?php
declare(strict_types=1);
namespace RPC\Push;
interface PushInterface
{
public function sendSmsCode(string $mobile, string $code): bool;
}
- 服務端實現接口
<?php
declare(strict_types=1);
namespace App\RPC;
use RPC\Push\PushInterface;
use Hyperf\RpcMultiplex\Constant;
use Hyperf\RpcServer\Annotation\RpcService;
#[RpcService(name: PushInterface::class, server: 'rpc', protocol: Constant::PROTOCOL_DEFAULT)]
class PushService implements PushInterface
{
public function sendSmsCode(string $mobile, string $code): bool
{
// 實際處理邏輯
return true;
}
}
- 客户端調用
<?php
use Hyperf\Context\ApplicationContext;
use RPC\Push\PushInterface;
ApplicationContext::getContainer()->get(PushInterface::class)->sendSmsCode('18600000001', '6666');
