1.Fist make sure your Etcd env is correct,the set this necessary param.
//Create ShenYuEtcdClient start
ecp := &etcd_client.EtcdClientParam{
EtcdServers: []string{"http://127.0.0.1:2379"}, // require user provider
UserName : "" // optional param etcd userName
Password : "" // optional param etcd pwd
TTL: 50, // optional param key live
}
sdkClient := shenyu_sdk_client.GetFactoryClient(constants.ETCD_CLIENT)
client, createResult, err := sdkClient.NewClient(ecp)
if !createResult && err != nil {
logger.Fatal("Create ShenYuEtcdClient error : %v", err)
}
etcd := client.(*etcd_client.ShenYuEtcdClient)
defer etcd.Close()
//Create ShenYuEtcdClient end
2. Prepare your service metaData to register
//metaData is necessary param, this will be register to shenyu gateway to use
metaData1 := &model.MetaDataRegister{
AppName: "testMetaDataRegister1", //require user provide
Path: "your/path1", //require user provide
Enabled: true, //require user provide
Host: "127.0.0.1", //require user provide
Port: "8080", //require user provide
}
metaData2 := &model.MetaDataRegister{
AppName: "testMetaDataRegister2", //require user provide
Path: "your/path2", //require user provide
Enabled: true, //require user provide
Host: "127.0.0.1", //require user provide
Port: "8181", //require user provide
}
3.use client to invoke RegisterServiceInstance
//register multiple metaData
registerResult1, err := etcd.RegisterServiceInstance(metaData1)
if !registerResult1 && err != nil {
logger.Fatal("Register etcd Instance error : %v", err)
}
registerResult2, err := etcd.RegisterServiceInstance(metaData2)
if !registerResult2 && err != nil {
logger.Fatal("Register etcd Instance error : %v", err)
}
//do your logic
4.use client to invoke DeregisterServiceInstance
//your can chose to invoke,not require
deRegisterResult1, err := etcd.DeregisterServiceInstance(metaData1)
if err != nil {
panic(err)
}
deRegisterResult2, err := etcd.DeregisterServiceInstance(metaData2)
if err != nil {
panic(err)
}
5.use client to GetServiceInstanceInfo
//GetServiceInstanceInfo start
instanceDetail, err := etcd.GetServiceInstanceInfo(metaData1)
nodes1, ok := instanceDetail.([]*model.MetaDataRegister)
if !ok {
logger.Fatal("get etcd client metaData error %v:", err)
}
//range nodes
for index, node := range nodes1 {
nodeJson, err := json.Marshal(node)
if err == nil {
logger.Info("GetNodesInfo ,success Index", index, string(nodeJson))
}
}
instanceDetail2, err := etcd.GetServiceInstanceInfo(metaData2)
nodes2, ok := instanceDetail2.([]*model.MetaDataRegister)
if !ok {
logger.Fatal("get etcd client metaData error %v:", err)
}
//GetServiceInstanceInfo end
