基于多路复用的 RPC 组件

本组件基于 TCP 协议,多路复用的设计借鉴于 AMQP 组件。

安装

composer require hyperf/rpc-multiplex

Server 配置

修改 config/autoload/server.php 配置文件,以下配置删除了不相干的配置。

settings 设置中,分包规则不允许修改,只可以修改 package_max_length,此配置需要 ServerClient 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,
            ],
        ],
    ],
];

创建 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',
            // 这个消费者要从哪个服务中心获取节点信息,如不配置则不会从服务中心获取节点信息
            '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' => [
                    // 包体最大值,若小于 Server 返回的数据大小,则会抛出异常,故尽量控制包体大小
                    'package_max_length' => 1024 * 1024 * 2,
                ],
                // 重试次数,默认值为 2
                'retry_count' => 2,
                // 重试间隔,毫秒
                'retry_interval' => 100,
                // 多路复用客户端数量
                'client_count' => 4,
                // 心跳间隔 非 numeric 表示不开启心跳
                'heartbeat' => 30,
            ],
        ],
    ],
];

注册中心

如果需要使用注册中心,则需要手动添加以下监听器

<?php
return [
    Hyperf\RpcMultiplex\Listener\RegisterServiceListener::class,
];
