# 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。
|
|
|
|
> 暂不支持注册中心
|
|
|
|
## 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 `Server` 和 `Client` 保持一致。
|
|
|
|
```php
|
|
<?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
|
|
<?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
|
|
<?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',
|
|
'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,
|
|
],
|
|
],
|
|
],
|
|
];
|
|
|
|
```
