    一.环境

    1.docker 运行一个hyperf的镜像,一个console镜像

    • hyperf镜像
    docker run --name hyperf1 -v E:\Web\Docker\Hyperf\:/data/project -p 9501:9501 -p 9502:9502 -p 9503:9503 -it --privileged -u root --entrypoint /bin/sh hyperf/hyperf:8.0-alpine-v3.14-swoole  
    
    • 1
    • consul镜像
    docker pull consul
    docker run --name=consul -p 8500:8500 -d consul

    使用ipconfig查看本机的ip,然后用公网ip+端口的方式访问
    在这里插入图片描述

    2.下载框架

    composer create-project hyperf/hyperf-skeleton

    选择json-rpc组件

    3.安装所需要的各个依赖(很多安装包 ,最好全部都安装一次,因为少安装依赖包中间出了很多bug)

    composer require hyperf/service-governance-consul
    # 我忘记了,只写composer.json文件
    #provider(服务提供者的composer.json)
     "require": {

    二.服务提供者

    1. 通过@RpcService注解对一个类进行定义即可发布这个服务
    • provider/app/JsonRpc/CalculatorServiceInterface.php
    <?php
    declare(strict_types=1);
    namespace App\JsonRpc;
    interface CalculatorServiceInterface{
        public function add(int $a,int $b);
    }

    • 4
    • 5
    • 6
    • provider/app/JsonRpc/CalculatorService.php
    <?php
    
    namespace App\JsonRpc;
    
    use Hyperf\RpcServer\Annotation\RpcService;
    
    /**
     * @RpcService(name="CalculatorService", protocol="jsonrpc-http", server="jsonrpc-http", publishTo="consul")
     */
    class CalculatorService implements CalculatorServiceInterface
    {
        // 实现一个加法方法,这里简单的认为参数都是 int 类型
        public function add(int $a, int $b): int
        {
            // 这里是服务方法的具体实现
            return $a + $b;
        }
    }
    
    • 1

    • 7
    • 8

    • 12
    • 13
    • 14
    • 15
    • 16
    • 17
    • 18

    @RpcService 共有 4 个参数:
    name 属性为定义该服务的名称,这里定义一个全局唯一的名字即可,Hyperf 会根据该属性生成对应的 ID 注册到服务中心去;
    protocol 属性为定义该服务暴露的协议,目前仅支持 jsonrpc-http, jsonrpc, jsonrpc-tcp-length-check ,分别对应于 HTTP 协议和 TCP 协议下的两种协议,默认值为 jsonrpc-http,这里的值对应在 Hyperf\Rpc\ProtocolManager 里面注册的协议的 key,它们本质上都是 JSON RPC 协议,区别在于数据格式化、数据打包、数据传输器等不同。
    server 属性为绑定该服务类发布所要承载的 Server,默认值为 jsonrpc-http,该属性对应 config/autoload/server.php 文件内 servers 下所对应的 name,这里也就意味着我们需要定义一个对应的 Server;
    publishTo 属性为定义该服务所要发布的服务中心,目前仅支持 consul、nacos 或为空,为空时代表不发布该服务到服务中心去,但也就意味着您需要手动处理服务发现的问题,要使用此功能需安装 hyperf/service-governance 组件及对应的驱动依赖,具体可参考 服务注册 章节;

    • 使用 @RpcService 注解需 use Hyperf\RpcServer\Annotation\RpcService; 命名空间。
    1. 定义server
    • provider/config/autoload/server.php
    <?php
    
    declare(strict_types=1);
    /**
     * This file is part of Hyperf.
     *
     * @link     https://www.hyperf.io
     * @document https://hyperf.wiki
     * @contact  group@hyperf.io
     * @license  https://github.com/hyperf/hyperf/blob/master/LICENSE

    3.安装consul扩展包,修改配置文件

    composer require hyperf/consul 
    #服务治理组件,不然 publishTo 不会生效
    composer require hyperf/service-governance 
    #发布consul组件的配置到app,config目录会生成一个consul.php文件
    php bin/hyperf.php vendor:publish hyperf/consul

            'register' => true,
        ],
        'providers' => [],
        'drivers' => [
            'consul' => [

                'token' => '',
                'check' => [
                    'deregister_critical_service_after' => '90m',
                    'interval' => '1s',
                ],
            ],
    
        ],

    直接使用php bin/hyperf.php start启动,如图所示:

    三. 服务消费者

    1.在 config/autoload/services.php 配置文件内进行一些简单的配置,即可通过动态代理自动创建消费者类

    • consumer/config/autoload/services.php
    <?php
    use App\JsonRpc\CalculatorServiceInterface;
    return [
     //服务消费者相关配置
        'consumers' =>[
            //name和服务提供者name相同
            [
                'name' => 'CalculatorService',
            //服务接口名,可选,默认值等于name配置的值,如果name直接定义为接口类可忽略此行配置
            'service' => CalculatorServiceInterface::class,
            //对应容器镜像id,可选,默认值等于service配置的值,用于定义依赖注入的key
            'id' =>\App\JsonRpc\CalculatorServiceInterface::class,
            //服务提供者的服务协议
             'protocol' => 'jsonrpc-http',
            //负载均衡算法
             'load_balancer' => 'random',
            //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://10.68.47.88:8500'
            ],
    //
            // 如果没有指定上面的 registry 配置,即为直接对指定的节点进行消费,通过下面的 nodes 参数来配置服务提供者的节点信息
    //        'nodes' => [
    //            ['host' => '127.0.0.1', 'port' => 9502],
    //        ],
    
    
            'options' => [
                'connect_timeout' => 5.0,
                'recv_timeout' => 5.0,
                'settings'  => [
                    'open_eof_split' =>  true,
                    'package_eof' => "\r\n",
                ],
                'retry_count' => 2,
                'retyr_interval' => 100,
                'heartbeat'  => 30,
                'pool' => [
                    'min_connections' => 1,
                    'max_connections' => 32,
                    'connect_timeout' => 10.0,
                    'wait_timeout' => 3.0,
                    'heartbeat' => -1,
                    'max_idle_time' => 60.0,
                ]
            ]
            ],
        ],
    
    ];

    2.在应用启动时会自动创建客户端类的代理对象,并在容器中使用配置项 id 的值(如果未设置,会使用配置项 service 值代替)来添加绑定关系,这样就和手工编写的客户端类一样,通过注入 CalculatorServiceInterface 接口来直接使用客户端。

    • consumer/app/JsonRpc/CalculatorServiceInterface.php
    <?php
    declare(strict_types=1);
    namespace App\JsonRpc;
    interface CalculatorServiceInterface{
        public function add(int $a,int $b);
    }

    {
    
    
         /**

          * @var CalculatorServiceInterface
          */
        public $calculatorService;
    
        public function index()
        {
    
    //        return $this->calculatorService->add(1,2); //add()方法不存在
              $client = ApplicationContext::getContainer()->get(CalculatorServiceInterface::class);
               var_dump(get_class($client));
              $value = $client->add(10,20);
              return $value;
        }
    }
