hyperf搭建微服务 - 1

Posted 2023-03-29

参考技术A UserService.php

UserServiceInterface.php

config/autoload/services.php

UserController.php

UserServiceInterface.php

修改config/routes.php为如下：

http://127.0.0.1:9501/user/getUserInfo?id=5
输出："id":5,"name":"黄翠刚"

Hyperf jsonrpc 服务的搭建

JSON-RPC，是一个无状态且轻量级的远程过程调用（RPC）传送协议，其传递内容透过 JSON 为主。

我们需要布置两台服务，一台Provider提供服务，另外一台Consumer消费服务

 

准备工作

1、所需类库

composer require hyperf/json-rpc

composer require hyperf/rpc-server

composer require hyperf/rpc-client

composer require hyperf/consul

composer require hyperf/service-governance

2、工具

Mac环境下

安装consul   brew install consul 

启动consul   brew services start consul

 

3、Provider的配置 

1、服务提供类

<?php
namespace AppRpc;
use HyperfRpcServerAnnotationRpcService;
/**
* @RpcService(name="CalculatorService",protocol="jsonrpc-http",server="jsonrpc-http")
*/
class CalculatorService implements CalculatorServiceInterface
{
    public function add(int $a, int $b): int
    {
        return $a + $b;
    }

    public function minus(int $a, int $b): int
    {
        return $a - $b;
    }
} 

2、接口类

<?php
namespace AppRpc;
interface CalculatorServiceInterface
{
    public function add(int $a, int $b): int;
    public function minus(int $a, int $b): int;
} 

 

 

3、配置文件 service.php

‘servers‘ => [
    ...
    [
        ‘name‘ => ‘jsonrpc-http‘,
        ‘type‘ => Server::SERVER_HTTP,
        ‘host‘ => ‘0.0.0.0‘,
        ‘port‘ => 9802,
        ‘sock_type‘ => SWOOLE_SOCK_TCP,
        ‘callbacks‘ => [
            SwooleEvent::ON_REQUEST => [HyperfJsonRpcHttpServer::class, ‘onRequest‘],
        ],
    ],
],

 

 

3、Consumer 的配置 

1、接口类

<?php
namespace AppRpc;
interface CalculatorServiceInterface
{
    public function add(int $a, int $b): int;
    public function minus(int $a, int $b): int;
} 

 

2、配置文件 services.php

return [

    ‘consumers‘ => [

        [

            ‘name‘    => ‘CalculatorService‘,

            ‘service‘ => AppRpcCalculatorServiceInterface::class,

            ‘nodes‘   => [

                [

                   ‘host‘ => ‘0.0.0.0‘,

                    ‘port‘ => 9802

                ],

            ],

        ],

    ],

]; 

3、调用

 

<?php
namespace AppController;
use AppRpcCalculatorServiceInterface;
use HyperfDiAnnotationInject;
use HyperfHttpServerAnnotationAutoController;
/**
 * @AutoController()
 */
class IndexController extends AbstractController
{
    /**
     * @Inject()
     * @var CalculatorServiceInterface
     */
    private $calculatorService;

    public function rpc()
    {
        return $this->calculatorService->minus(10,2);
    }
}

 

4、使用consul 

如果需要使用 consul来管理服务，则需要做如下操作

1).修改Provider具体的服务类,注解添加属性 publishTo

/**
* @RpcService(name="CalculatorService",protocol="jsonrpc-http",server="jsonrpc-http",publishTo="consul") 
*/ 

2).Provider服务发布

php bin/hyperf.php vendor:publish hyperf/consul

执行完毕后会形成一个配置文件 consul.php

3).Conusmer修改配置

return [
    ‘consumers‘ => [
        [
            ‘name‘    => ‘CalculatorService‘,
            ‘service‘ => AppRpcCalculatorServiceInterface::class,
　　　　　　　registry‘ => [

                ‘protocol‘ => ‘consul‘,

                ‘address‘ => ‘http://127.0.0.1:8500‘,//对应Provider 中  consul.php配置项
            ]

 　　　　], 
　　], 
]; 

 

4）重新启动Provider和Consumer
