Nacos示例
以Nacos方式注册到ShenYu网关
1.首先确保你的nacos环境是正确，然后设置这些nacos必要的参数 .
//设置nacos环境配置
ncp := &nacos_client.NacosClientParam{
IpAddr: "console.nacos.io",
Port: 80,
NamespaceId: "e525eafa-f7d7-4029-83d9-008937f9d468",
}
2. 准备你要注册服务的元数据信息
//元数据是必要的参数，这将注册到shenyu网关使用
metaData := &model.URIRegister{
Protocol: "testMetaDataRegister", //需要用户提供
AppName: "testURLRegister", //需要用户提供
ContextPath: "contextPath", //需要用户提供
RPCType: constants.RPCTYPE_HTTP, //需要用户提供
Host: "127.0.0.1", //需要用户提供
Port: "8080", //需要用户提供
}
metaDataStringJson, _ := json.Marshal(metaData)
3.准备你要注册服务的实例消息(包括元数据)
//初始化Nacos注册实例信息
nacosRegisterInstance := vo.RegisterInstanceParam{
Ip: "10.0.0.10", //需要用户提供
Port: 8848, //需要用户提供
ServiceName: "demo.go", //需要用户提供
Weight: 10, //需要用户提供
Enable: true, //需要用户提供
Healthy: true, //需要用户提供
Ephemeral: true, //需要用户提供
Metadata: map[string]string{"contextPath": "contextPath", "uriMetadata": string(metaDataStringJson)},
}
4. 获取ShenYu nacos的客户端
sdkClient := shenyu_sdk_client.GetFactoryClient(constants.NACOS_CLIENT)
result, createResult, err := sdkClient.NewClient(ncp)
if !createResult && err != nil {
logger.Fatal("Create nacos client error : %v", err)
}
nc := &nacos_client.ShenYuNacosClient{
NacosClient: result.(*naming_client.NamingClient),
}
5.使用客户端调用RegisterNacosInstance方法
registerResult, err := nc.RegisterServiceInstance(nacosRegisterInstance)
if !registerResult && err != nil {
logger.Fatal("Register nacos Instance error : %v", err)
}
//do your logic
6.使用客户端调用DeregisterServiceInstance方法
//DeregisterServiceInstance start
deregisterInstanceParam := vo.DeregisterInstanceParam{
Ip: "10.0.0.10",
Port: 8848,
ServiceName: "demo.go",
Ephemeral: true,
//Cluster: "cluster-a", // default value is DEFAULT
GroupName: "group-a", // default value is DEFAULT_GROUP
}
serviceInstance, err := nc.DeregisterServiceInstance(deregisterInstanceParam)
if !serviceInstance && err != nil {
logger.Info("DeregisterServiceInstance result : %v", serviceInstance)
}
//do your logic
7.使用客户端调用GetServiceInstanceInfo方法
instanceInfo, err := nc.GetServiceInstanceInfo(queryData)
if instanceInfo == nil {
logger.Fatal("Register nacos Instance error : %v", err)
}
//do your logic
