hyperf框架nacos服务注册、配置心和json_rpc调用

• nacos服务注册

  • 安装统一接入层
    composer require hyperf/service-governance

  • 安装nacos
    composer require hyperf/service-governance-nacos

  • 配置文件(组件由 config/autoload/services.php 配置文件来驱动)

    		return [
    				    'enable' => [
    				        // 开启服务发现
    				        'discovery' => true,
    				        // 开启服务注册
    				        'register' => true,
    				    ],
    				    // 服务消费者相关配置
    				    'consumers' => [],
    				    // 服务提供者相关配置
    				    'providers' => [],
    				    // 服务驱动相关配置
    				    'drivers' => [
    				        'consul' => [
    				            'uri' => 'http://127.0.0.1:8500',
    				            'token' => '',
    				            'check' => [
    				                'deregister_critical_service_after' => '90m',
    				                'interval' => '1s',
    				            ],
    				        ],
    				        'nacos' => [
    				            // nacos server url like https://nacos.hyperf.io, Priority is higher than host:port
    				            // 'url' => '',
    				            // The nacos host info
    				            'host' => '127.0.0.1',
    				            'port' => 8848,
    				            // The nacos account info
    				            'username' => null,
    				            'password' => null,
    				            'guzzle' => [
    				                'config' => null,
    				            ],
    				            'group_name' => 'api',
    				            'namespace_id' => 'namespace_id',
    				            'heartbeat' => 5,
    				            'ephemeral' => false, // 是否注册临时实例
    				        ],
    				    ],
    				];
    

    

• nacos配置中心

  • 配置中心统一接入层
    composer require hyperf/config-center
  • Nacos 安装
    composer require hyperf/config-nacos
  • 配置中心 (config目录下config_center.php)

    	'drivers' => [
    			'nacos' => [
                'driver' => Hyperf\ConfigNacos\NacosDriver::class,
                // 配置合并方式，支持覆盖和合并
                'merge_mode' => Hyperf\ConfigNacos\Constants::CONFIG_MERGE_OVERWRITE,
                'interval' => 3,
                // 如果对应的映射 key 没有设置，则使用默认的 key
                'default_key' => 'nacos_config',
                'listener_config' => [
                    // dataId, group, tenant, type, content
                    // 映射后的配置 KEY => Nacos 中实际的配置
                    'nacos_config' => [
                        'tenant' => 'tenant', // corresponding with service.namespaceId
                        'data_id' => 'hyperf-service-config',
                        'group' => 'DEFAULT_GROUP',
                    ],
                    'nacos_config.data' => [
                        'data_id' => 'hyperf-service-config-yml',
                        'group' => 'DEFAULT_GROUP',
                        'type' => 'yml',
                    ],
                ],
    		]
    

    
  • nacos配置和hyperf调用
    • 
      
      
      

• json_rpc调用

  • 安装
    composer require hyperf/json-rpc
    composer require hyperf/rpc-server(JSON RPC 服务端)
    composer require hyperf/rpc-client(JSON RPC 客户端)

  • 服务提供者

    		<?php
    		
    		namespace App\JsonRpc;
    		
    		use Hyperf\RpcServer\Annotation\RpcService;
    		
    		/**
    		 * 注意，如希望通过服务中心来管理服务，需在注解内增加 publishTo 属性
    		 */
    		#[RpcService(name: "CalculatorService", protocol: "jsonrpc-http", server: "jsonrpc-http")]
    		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;
    		    }
    		}
    		
    		<?php
    		
    		use Hyperf\Server\Server;
    		use Hyperf\Server\Event;
    		
    		return [
    		    // 这里省略了该文件的其它配置
    		    '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'],
    		            ],
    		        ],
    		    ],
    		];
    

    

  • 发布到服务中心

    		<?php
    		return [
    		    'enable' => [
    		        'discovery' => true,
    		        'register' => true,
    		    ],
    		    'consumers' => [],
    		    'providers' => [],
    		    'drivers' => [
    		        'consul' => [
    		            'uri' => 'http://127.0.0.1:8500',
    		            'token' => '',
    		        ],
    		        'nacos' => [
    		            // nacos server url like https://nacos.hyperf.io, Priority is higher than host:port
    		            // 'url' => '',
    		            // The nacos host info
    		            'host' => '127.0.0.1',
    		            'port' => 8848,
    		            // The nacos account info
    		            'username' => null,
    		            'password' => null,
    		            'guzzle' => [
    		                'config' => null,
    		            ],
    		            'group_name' => 'api',
    		            'namespace_id' => 'namespace_id',
    		            'heartbeat' => 5,
    		        ],
    		    ],
    		];
    

    

  • 定义消费者

    		<?php
    		
    		namespace App\JsonRpc;
    		
    		use Hyperf\RpcClient\AbstractServiceClient;
    		
    		class CalculatorServiceConsumer extends AbstractServiceClient implements CalculatorServiceInterface
    		{
    		    /**
    		     * 定义对应服务提供者的服务名称
    		     */
    		    protected string $serviceName = 'CalculatorService';
    		    
    		    /**
    		     * 定义对应服务提供者的服务协议
    		     */
    		    protected string $protocol = 'jsonrpc-http';
    		
    		    public function add(int $a, int $b): int
    		    {
    		        return $this->__request(__FUNCTION__, compact('a', 'b'));
    		    }
    		}
    		services.php
    		<?php
    		return [
    		    // 此处省略了其它同层级的配置
    		    'consumers' => [
    		        [
    		            // 对应消费者类的 $serviceName
    		            'name' => 'CalculatorService',
    		            // 这个消费者要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' => 'nacos',
    		                'address' => 'http://192.168.61.111:8848',
    		            ],
    		            // 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' => '172.19.60.77', 'port' => 9504],
    		//            ],
    		        ]
    		    ],
    		    'drivers' => [
    		        'nacos' => [
    		            // nacos server url like https://nacos.hyperf.io, Priority is higher than host:port
    		            // 'url' => '',
    		            // The nacos host info
    		            'host' => '192.168.61.111',
    		            'port' => 8848,
    		            // The nacos account info
    		            'username' => 'nacos',
    		            'password' => 'nacos',
    		            'guzzle' => [
    		                'config' => null,
    		            ],
    		            'group_name' => 'DEFAULT_GROUP',
    		            'namespace_id' => '8ab0c40e-3e16-4809-836d-a2947589276f',
    		            'heartbeat' => 5,
    		            'ephemeral' => false, // 是否注册临时实例
    		        ],
    		    ],
    		];
    

    

    这样我们便可以通过 CalculatorService 类来实现对服务的消费了，为了让这里的关系逻辑更加的合理，还应该在 config/autoload/dependencies.php 内定义 CalculatorServiceInterface 和 CalculatorServiceConsumer 的关系，示例如下：

    return [
        App\JsonRpc\CalculatorServiceInterface::class => App\JsonRpc\CalculatorServiceConsumer::class,
    ];
