安裝 Hyperf，使用Docker運行

# 環(huán)境win10，CMD命令行窗口,執(zhí)行如下命令
# 這個容器我們用來運行Hyperf(多映射幾個端口，方便后面使用)
docker run --name hyperf_rpc -v E:\phpstudy_pro\WWW\docker\workspace\skeleton:/data/project -p 9501:9501 -p 9502:9502 -p 9503:9503  -p 9504:9504  -p 9505:9505  -p 9506:9506  -p 9507:9507  -p 9508:9508  -p 9509:9509  -it --privileged -u root --entrypoint sh hyperf/hyperf:7.4-alpine-v3.11-swoole

# 設(shè)置國內(nèi)鏡像
/ # composer config -g repo.packagist composer https://mirrors.aliyun.com/composer

# 進入到我們映射的主機目錄
/ # cd /data/project/
# 安裝 Hyperf（所有選項全部選擇默認，直接回車到底）
/data/project # composer create-project hyperf/hyperf-skeleton hyperf-rpc-client

# 安裝JSON RPC 服務(wù)組件
/data/project # cd hyperf-rpc-client/
/data/project/hyperf-rpc-client # composer require hyperf/json-rpc
/data/project/hyperf-rpc-client # composer require hyperf/rpc-server
/data/project/hyperf-rpc-client # composer require hyperf/rpc-client
/data/project/hyperf-rpc-client # composer require hyperf/service-governance

# 運行hyperf試試（可以看到啟動成功，端口9501，并且訪問成功http://127.0.0.1:9501/）
/data/project/hyperf-rpc-client # php bin/hyperf.php start 

編寫一個服務(wù)提供者，映射9503端口

基于上面的hyperf-rpc-client，復(fù)制一個出來，并且命名為hyperf-rpc-service-user,作為“用戶模塊”的一個微服務(wù),下面的修改，在這個代碼的基礎(chǔ)上修改

修改配置如下 config/autoload/server.php

<?php

declare(strict_types=1);

創(chuàng)建服務(wù)提供者

在/app目錄下新建JsonRpc目錄，并在此目錄下創(chuàng)建UserService.php、UserServiceInterface.php文件，文件內(nèi)容如下：

UserService.php

<?php

namespace App\JsonRpc;

use Hyperf\RpcServer\Annotation\RpcService;
use Hyperf\Contract\ConfigInterface;

/**
 * 注意，如希望通過服務(wù)中心來管理服務(wù)，需在注解內(nèi)增加 publishTo 屬性
 * @RpcService(name="UserService", protocol="jsonrpc-http", server="jsonrpc-http")
 */
class UserService implements UserServiceInterface
{
    // 獲取用戶信息
    public function getUserInfo(int $id)
    {
        return ['id' => $id, 'name' => '黃翠剛'];
    }
}

UserServiceInterface.php

<?php

namespace App\JsonRpc;

use Hyperf\RpcServer\Annotation\RpcService;

interface UserServiceInterface
{
    public function getUserInfo(int $id);
}

啟動

/data/project # cd /data/project/hyperf-rpc-service-user
/data/project/hyperf-rpc-service-user # php bin/hyperf.php start

修改hyperf-rpc-client代碼

創(chuàng)建services.php、UserController.php、UserServiceInterface.php文件，文件內(nèi)容如下：

config/autoload/services.php

<?php
declare(strict_types=1);
/**
 * This file is part of Hyperf.
 *
 * @link     https://www.hyperf.io
 * @document https://hyperf.wiki

 * @license  https://github.com/hyperf/hyperf/blob/master/LICENSE
 */
return [
    'consumers' => [
        [
            // 用戶服務(wù)
            'name' => 'UserService',
            // 服務(wù)接口名，可選，默認值等于 name 配置的值，如果 name 直接定義為接口類則可忽略此行配置，如 name 為字符串則需要配置 service 對應(yīng)到接口類
            'service' => \App\JsonRpc\UserServiceInterface::class,
            // 服務(wù)提供者的服務(wù)協(xié)議，可選，默認值為 jsonrpc-http
            'protocol' => 'jsonrpc-http',
            'nodes' => [
                // Provide the host and port of the service provider.
                ['host' => '127.0.0.1', 'port' => 9503],
            ],
        ]
];

UserController.php

<?php

declare(strict_types=1);

namespace App\Controller;

use Hyperf\HttpServer\Contract\RequestInterface;
use App\JsonRpc\UserServiceInterface;

class UserController
{

    public $userService;
    public function __construct(UserServiceInterface $userService)
    {
        $this->userService = $userService;
    }

    // 獲取用戶信息
    public function getUserInfo(RequestInterface $request)
    {
        // 從請求中獲得 id 參數(shù)
        $id = $request->input('id', 1);
        $ret = $this->userService->getUserInfo((int)$id);
        return $ret;
    }
}

UserServiceInterface.php

<?php

namespace App\JsonRpc;

use Hyperf\RpcServer\Annotation\RpcService;

interface UserServiceInterface
{
    public function getUserInfo(int $id);
}

修改config/routes.php為如下：

<?php

declare(strict_types=1);
/**

 *
 * @link     https://www.hyperf.io
 * @document https://hyperf.wiki
 * @contact  group@hyperf.io

 */
use Hyperf\HttpServer\Router\Router;

Router::addRoute(['GET', 'POST', 'HEAD'], '/', 'App\Controller\IndexController@index');

Router::addRoute(['GET', 'POST', 'HEAD'], '/user/getUserInfo', 'App\Controller\UserController@getUserInfo');

Router::get('/favicon.ico', function () {
    return '';
});

訪問OK

http://127.0.0.1:9501/user/getUserInfo?id=5
輸出：{"id":5,"name":"黃翠剛"}
