## RPC基础概念与Swoft实现原理
### 1.1 RPC技术核心原理
远程过程调用(Remote Procedure Call)是一种计算机通信协议,允许程序像调用本地方法一样调用另一台计算机上的子程序,主要包含以下核心组件:
- **服务注册中心**:管理服务提供者的地址信息
- **序列化协议**:JSON/XML/Protobuf/Thrift等
- **通信协议**:TCP/HTTP/gRPC等
- **负载均衡**:随机/轮询/一致性哈希等算法
### 1.2 Swoft的RPC实现架构
Swoft 2.x采用协程化的RPC实现,主要组件关系如下:
+——————-+ +——————-+ +——————-+ | Service Client | —-> | Service Center | <—- | Service Provider | +——————-+ +——————-+ +——————-+ ^ | | v +——————-+ +——————-+ | Swoft\RPC\ | | @Service注解 | | Client\Proxy | +——————-+ +——————-+
关键特性:
- 基于Swoole协程实现高并发
- 内置JSON-RPC协议支持
- 服务自动发现与熔断机制
- 注解驱动开发模式

## Swoft 2.0.6 RPC服务端配置
### 2.1 基础环境准备
```bash
# 创建项目
composer create-project swoft/swoft swoft-rpc-demo 2.0.6
# 必要扩展检查
php --ri swoole
php --ri redis
config/beans/base.php
关键配置:
return [
'service' => [
'class' => \Swoft\Rpc\Server\ServiceServer::class,
'port' => 18307,
'listener' => [
'rpc' => \Swoft\Rpc\Server\Listener\ServiceListener::class
],
],
'serviceServer' => [
'class' => \Swoft\Rpc\Server\ServiceServer::class,
'port' => 18307,
],
'rpcServer' => [
'class' => \Swoft\Rpc\Server\ServiceServer::class,
'port' => 18308,
],
];
app/Rpc/Interfaces/UserServiceInterface.php
:
<?php
namespace App\Rpc\Interfaces;
interface UserServiceInterface
{
/**
* @param int $id
* @return array
* @RpcService()
*/
public function getUserInfo(int $id): array;
/**
* @param string $name
* @param int $age
* @return bool
* @RpcService()
*/
public function createUser(string $name, int $age): bool;
}
app/Rpc/Services/UserService.php
:
<?php
namespace App\Rpc\Services;
use App\Rpc\Interfaces\UserServiceInterface;
use Swoft\Rpc\Server\Annotation\Mapping\Service;
/**
* @Service()
*/
class UserService implements UserServiceInterface
{
private $users = [
1 => ['id' => 1, 'name' => 'Alice', 'age' => 28],
2 => ['id' => 2, 'name' => 'Bob', 'age' => 32]
];
public function getUserInfo(int $id): array
{
return $this->users[$id] ?? [];
}
public function createUser(string $name, int $age): bool
{
$newId = max(array_keys($this->users)) + 1;
$this->users[$newId] = compact('name', 'age');
return true;
}
}
config/beans/base.php
添加:
return [
'rpcClient' => [
'class' => \Swoft\Rpc\Client\Client::class,
'packer' => \Swoft\Rpc\Client\Packer\JsonPacker::class,
],
'user.pool' => [

*/

return compact('user');
}
}
/** @var \Swoft\Rpc\Client\Client $client */
$client = \Swoft::getBean('rpcClient');
$result = $client->call('UserService', 'getUserInfo', [1]);
<?php
$fp = stream_socket_client('tcp://127.0.0.1:18307', $errno, $errstr, 3);
if (!$fp) {
throw new \RuntimeException("Connection failed: $errno - $errstr");
}
$data = [
'jsonrpc' => '2.0',
'method' => 'UserService.getUserInfo',
'params' => [1],
'id' => uniqid()
];
fwrite($fp, json_encode($data)."\r\n");

}
'user.pool' => [
