JSON-RPC实战指南

服务提供者实现

首先定义服务接口契约：

<?php

namespace App\JsonRpc;

interface CalculatorServiceInterface
{
    public function add(int $a, int $b): int;
    
    public function subtract(int $a, int $b): int;
    
    public function multiply(int $a, int $b): int;
    
    public function divide(int $a, int $b): float;
}

实现服务提供者：

<?php

namespace App\JsonRpc;

use Hyperf\RpcServer\Annotation\RpcService;

#[RpcService(
    name: "CalculatorService", 
    protocol: "jsonrpc-http", 
    server: "jsonrpc-http",
    publishTo: "consul"
)]
class CalculatorService implements CalculatorServiceInterface
{
    public function add(int $a, int $b): int
    {
        return $a + $b;
    }
    
    public function subtract(int $a, int $b): int
    {
        return $a - $b;
    }
    
    public function multiply(int $a, int $b): int
    {
        return $a * $b;
    }
    
    public function divide(int $a, int $b): float
    {
        if ($b === 0) {
            throw new \InvalidArgumentException('Division by zero');
        }
        return $a / $b;
    }
}

服务端配置

配置JSON-RPC服务器：

<?php
// config/autoload/server.php

use Hyperf\Server\Server;
use Hyperf\Server\Event;

return [
    'servers' => [
        [
            'name' => 'jsonrpc-http',
            'type' => Server::SERVER_HTTP,
            'host' => '0.0.0.0',
            'port' => 9504,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_REQUEST => [\Hyperf\JsonRpc\HttpServer::class, 'onRequest'],
            ],
        ],
        [
            'name' => 'jsonrpc-tcp',
            'type' => Server::SERVER_BASE,
            'host' => '0.0.0.0',
            'port' => 9503,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                Event::ON_RECEIVE => [\Hyperf\JsonRpc\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,
            ],
        ],
    ],
];

服务消费者配置

自动代理方式配置：

<?php
// config/autoload/services.php

return [
    'enable' => [
        'discovery' => true,
        'register' => true,
    ],
    'consumers' => [
        [
            'name' => 'CalculatorService',
            'service' => \App\JsonRpc\CalculatorServiceInterface::class,
            'protocol' => 'jsonrpc-http',
            'load_balancer' => 'random',
            'registry' => [
                'protocol' => 'consul',
                'address' => 'http://127.0.0.1:8500',
            ],
            'options' => [
                'connect_timeout' => 5.0,
                'recv_timeout' => 5.0,
                'retry_count' => 2,
                'retry_interval' => 100,
            ],
        ],
    ],
    'drivers' => [
        'consul' => [
            'uri' => 'http://127.0.0.1:8500',
            'token' => '',
        ],
    ],
];

手动创建消费者类：

<?php

namespace App\JsonRpc;

use Hyperf\RpcClient\AbstractServiceClient;

class CalculatorServiceConsumer extends AbstractServiceClient implements CalculatorServiceInterface
{
    protected string $serviceName = 'CalculatorService';
    protected string $protocol = 'jsonrpc-http';

    public function add(int $a, int $b): int
    {
        return $this->__request(__FUNCTION__, compact('a', 'b'));
    }
    
    public function subtract(int $a, int $b): int
    {
        return $this->__request(__FUNCTION__, compact('a', 'b'));
    }
    
    public function multiply(int $a, int $b): int
    {
        return $this->__request(__FUNCTION__, compact('a', 'b'));
    }
    
    public function divide(int $a, int $b): float
    {
        return $this->__request(__FUNCTION__, compact('a', 'b'));
    }
}

gRPC深度集成

Proto文件定义

syntax = "proto3";

package calculator;

service Calculator {
    rpc Add (CalcRequest) returns (CalcResponse) {}
    rpc Subtract (CalcRequest) returns (CalcResponse) {}
    rpc Multiply (CalcRequest) returns (CalcResponse) {}
    rpc Divide (CalcRequest) returns (CalcResponse) {}
}

message CalcRequest {
    double a = 1;
    double b = 2;
}

message CalcResponse {
    double result = 1;
    string message = 2;
}

gRPC服务端实现

<?php

namespace App\Controller;

use Hyperf\HttpServer\Annotation\Controller;
use Hyperf\HttpServer\Annotation\PostMapping;
use Calculator\CalcRequest;
use Calculator\CalcResponse;

#[Controller(server: "grpc")]
class CalculatorController
{
    #[PostMapping(path: "/calculator.Calculator/Add")]
    public function add(CalcRequest $request): CalcResponse
    {
        $response = new CalcResponse();
        $response->setResult($request->getA() + $request->getB());
        $response->setMessage("Addition completed successfully");
        return $response;
    }
    
    #[PostMapping(path: "/calculator.Calculator/Subtract")]
    public function subtract(CalcRequest $request): CalcResponse
    {
        $response = new CalcResponse();
        $response->setResult($request->getA() - $request->getB());
        $response->setMessage("Subtraction completed successfully");
        return $response;
    }
}

gRPC客户端实现

<?php

namespace App\Grpc;

use Hyperf\GrpcClient\BaseClient;
use Calculator\CalcRequest;
use Calculator\CalcResponse;

class CalculatorClient extends BaseClient
{
    public function __construct(string $hostname, array $opts = [])
    {
        parent::__construct($hostname, $opts);
    }

    public function add(CalcRequest $request)
    {
        return $this->_simpleRequest(
            '/calculator.Calculator/Add',
            $request,
            [CalcResponse::class, 'decode']
        );
    }
    
    public function subtract(CalcRequest $request)
    {
        return $this->_simpleRequest(
            '/calculator.Calculator/Subtract',
            $request,
            [CalcResponse::class, 'decode']
        );
    }
}

服务注册与发现

Consul集成配置

<?php
// config/autoload/services.php

return [
    'enable' => [
        'discovery' => true,
        'register' => true,
    ],
    'consumers' => value(function () {
        $consumers = [];
        $registry = [
            'protocol' => 'consul',
            'address' => 'http://127.0.0.1:8500',
        ];
        
        // 自动为所有RPC服务创建消费者配置
        $services = [
            'CalculatorService' => \App\JsonRpc\CalculatorServiceInterface::class,
            'UserService' => \App\JsonRpc\UserServiceInterface::class,
            'OrderService' => \App\JsonRpc\OrderServiceInterface::class,
        ];
        
        foreach ($services as $name => $interface) {
            $consumers[] = [
                'name' => $name,
                'service' => $interface,
                'protocol' => 'jsonrpc-http',

                ],
            ];
        }
        
        return $consumers;
    }),
    'drivers' => [
        'consul' => [
            'uri' => 'http://127.0.0.1:8500',
            'token' => '',

            'namespace_id' => 'public',
            'heartbeat' => 5,
        ],
    ],
];

连接池管理

使用JsonRpcPoolTransporter提升性能：

<?php
// config/autoload/dependencies.php

use Hyperf\JsonRpc\JsonRpcPoolTransporter;
use Hyperf\JsonRpc\JsonRpcTransporter;

return [
    JsonRpcTransporter::class => JsonRpcPoolTransporter::class,
    
    // 连接池配置
    'jsonrpc_pool' => [
        'min_connections' => 10,
        'max_connections' => 100,
        'connect_timeout' => 10.0,
        'wait_timeout' => 3.0,
        'heartbeat' => -1,
        'max_idle_time' => 60.0,
    ],
];

熔断器与重试机制

<?php

namespace App\JsonRpc;

use Hyperf\RpcClient\AbstractServiceClient;
use Hyperf\CircuitBreaker\Annotation\CircuitBreaker;

class ResilientCalculatorService extends AbstractServiceClient implements CalculatorServiceInterface
{
    protected string $serviceName = 'CalculatorService';
    protected string $protocol = 'jsonrpc-http';

    #[CircuitBreaker(
        timeout: 5.0,
        failCounter: 3,
        successCounter: 2,
        fallback: "fallbackAdd"
    )]
    public function add(int $a, int $b): int
    {
        return $this->__request(__FUNCTION__, compact('a', 'b'));
    }
    
    public function fallbackAdd(int $a, int $b): int
    {
        // 降级逻辑：返回默认值或缓存值
        \Hyperf\Logger\LoggerFactory::get('rpc')->warning(
            'CalculatorService add method fallback triggered',
            ['a' => $a, 'b' => $b]
        );
        return 0; // 或者抛出特定的业务异常
    }
}

分布式追踪集成

<?php
// config/autoload/opentracing.php

return [
    'default' => 'jaeger',
    'enable' => [
        'guzzle' => true,
        'redis' => true,
        'db' => true,
        'method' => false,
    ],
    'tracer' => [
        'jaeger' => [
            'driver' => Hyperf\Tracer\Adapter\JaegerTracerFactory::class,

                    'db' => true,
                    'method' => false,
                ],
            ],
        ],
    ],
    'tags' => [
        'http_client' => [
            'http.url' => 'http.url',

        ],
        'db' => [
            'query' => 'query',
            'statement' => 'statement',
            'bindings' => 'bindings',
        ],
        'rpc' => [
            'service' => 'rpc.service',
            'method' => 'rpc.method',
            'protocol' => 'rpc.protocol',
        ],
    ],
];

性能优化策略

            ->get(CalculatorServiceInterface::class);
        
        $concurrent = new Concurrent(10); // 限制并发数为10
        
        $results = [];
        foreach ($operations as $index => $operation) {
            $results[$index] = $concurrent->create(function () use ($calculator, $operation) {
                switch ($operation['type']) {
                    case 'add':
                        return $calculator->add($operation['a'], $operation['b']);
                    case 'subtract':
                        return $calculator->subtract($operation['a'], $operation['b']);
                    case 'multiply':
                        return $calculator->multiply($operation['a'], $operation['b']);
                    case 'divide':
                        return $calculator->divide($operation['a'], $operation['b']);
                    default:
                        throw new \InvalidArgumentException("Unknown operation type: {$operation['type']}");
                }
            });
        }
        
        return $concurrent->wait();
    }
}

缓存策略优化

<?php

use Hyperf\RpcClient\AbstractServiceClient;
use Hyperf\Cache\Annotation\Cacheable;

class CachedCalculatorService extends AbstractServiceClient implements CalculatorServiceInterface
{
    protected string $serviceName = 'CalculatorService';
    protected string $protocol = 'jsonrpc-http';

    #[Cacheable(prefix: "calc_add", ttl: 3600)]
    public function add(int $a, int $b): int
    {
        return $this->__request(__FUNCTION__, compact('a', 'b'));
    }
    
    #[Cacheable(prefix: "calc_multiply", ttl: 3600)]
    public function multiply(int $a, int $b): int
