Etcd Example

The Etcd type Register

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
