设备如何使用go sdk轻松连接华为云IoT平台
本文分享自华为云社区《设备如何使用go sdk轻松连接华为云IoT平台》,作者:华为云IoT专家团 。
本文介绍使用huaweicloud-iot-device-sdk-go 连接华为云IoT平台,实现简单的华为云文档介绍的四个功能:设备连接鉴权、设备命令、设备消息和设备属性。huaweicloud-iot-device-sdk-go提供设备接入华为云IoT物联网平台的Go版本的SDK,提供设备和平台之间通讯能力,以及设备服务、网关服务、OTA等高级服务。IoT设备开发者使用SDK可以大大简化开发复杂度,快速的接入平台。
Gihub项目地址:huaweicloud-iot-device-sdk-go
安装和构建
安装和构建的过程取决于使用go的 modules(推荐) 还是还是GOPATH
Modules
如果你使用 modules 只需要导入包"github.com/ctlove0523/huaweicloud-iot-device-sdk-go"即可使用。当你使用go build命令构建项目时,依赖的包会自动被下载。注意使用go build命令构建时会自动下载最新版本,最新版本还没有达到release的标准可能存在一些尚未修复的bug。如果想使用稳定的发布版本可以从release 获取最新稳定的版本号,并在go.mod文件中指定版本号。
module example
go 1.15
require github.com/ctlove0523/huaweicloud-iot-device-sdk-go v0.0.1-alpha
GOPATH
如果你使用GOPATH,下面的一条命令即可实现安装
go get github.com/ctlove0523/huaweicloud-iot-device-sdk-go
使用API
创建设备并初始化
1、首先,在华为云IoT平台创建一个设备,设备的信息如下:
设备ID:5fdb75cccbfe2f02ce81d4bf_go-mqtt
设备密钥:123456789
2、使用SDK创建一个Device对象,并初始化Device。
// 创建一个设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
完整样例
import (
"fmt"
"github.com/ctlove0523/huaweicloud-iot-device-sdk-go"
"time"
)
func main()
// 创建一个设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
if device.IsConnected()
fmt.Println("device connect huawei iot platform success")
else
fmt.Println("device connect huawei iot platform failed")
iot-mqtts.cn-north-4.myhuaweicloud.com为华为IoT平台(基础班)在华为云北京四的访问端点,如果你购买了标准版或企业版,请将iot-mqtts.cn-north-4.myhuaweicloud.com更换为对应的MQTT协议接入端点。
设备处理平台下发的命令
1、首先,在华为云IoT平台创建一个设备,设备的信息如下:
设备ID:5fdb75cccbfe2f02ce81d4bf_go-mqtt
设备密钥:123456789
2、使用SDK创建一个Device对象,并初始化Device。
// 创建一个设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
if device.IsConnected()
fmt.Println("device connect huawei iot platform success")
else
fmt.Println("device connect huawei iot platform failed")
3、注册命令处理handler,支持注册多个handler并且按照注册的顺序回调
// 添加用于处理平台下发命令的callback
device.AddCommandHandler(func(command iot.Command) bool
fmt.Println("First command handler begin to process command.")
return true
)
device.AddCommandHandler(func(command iot.Command) bool
fmt.Println("Second command handler begin to process command.")
return true
)
4、通过应用侧API向设备下发一个命令,可以看到程序输出如下:
device connect huawei iot platform success
First command handler begin to process command.
Second command handler begin to process command.
完整样例
import (
"fmt"
"github.com/ctlove0523/huaweicloud-iot-device-sdk-go"
"time"
)
// 处理平台下发的同步命令
func main()
// 创建一个设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
if device.IsConnected()
fmt.Println("device connect huawei iot platform success")
else
fmt.Println("device connect huawei iot platform failed")
// 添加用于处理平台下发命令的callback
device.AddCommandHandler(func(command iot.Command) bool
fmt.Println("First command handler begin to process command.")
return true
)
device.AddCommandHandler(func(command iot.Command) bool
fmt.Println("Second command handler begin to process command.")
return true
)
time.Sleep(1 * time.Minute)
设备支持的命令定义在产品中
设备消息
1、首先,在华为云IoT平台创建一个设备,设备的信息如下:
设备ID:5fdb75cccbfe2f02ce81d4bf_go-mqtt
设备密钥:123456789
2、使用SDK创建一个Device对象,并初始化Device。
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
设备消息上报
message := iot.Message
ObjectDeviceId: uuid.NewV4().String(),
Name: "Fist send message to platform",
Id: uuid.NewV4().String(),
Content: "Hello Huawei IoT Platform",
device.SendMessage(message)
平台消息下发
接收平台下发的消息,只需注册消息处理handler,支持注册多个handler并按照注册顺序回调。
// 注册平台下发消息的callback,当收到平台下发的消息时,调用此callback.
// 支持注册多个callback,并且按照注册顺序调用
device.AddMessageHandler(func(message iot.Message) bool
fmt.Println("first handler called" + iot.Interface2JsonString(message))
return true
)
device.AddMessageHandler(func(message iot.Message) bool
fmt.Println("second handler called" + iot.Interface2JsonString(message))
return true
)
完整样例
import (
"fmt"
iot "github.com/ctlove0523/huaweicloud-iot-device-sdk-go"
uuid "github.com/satori/go.uuid"
"time"
)
func main()
// 创建一个设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
// 注册平台下发消息的callback,当收到平台下发的消息时,调用此callback.
// 支持注册多个callback,并且按照注册顺序调用
device.AddMessageHandler(func(message iot.Message) bool
fmt.Println("first handler called" + iot.Interface2JsonString(message))
return true
)
device.AddMessageHandler(func(message iot.Message) bool
fmt.Println("second handler called" + iot.Interface2JsonString(message))
return true
)
//向平台发送消息
message := iot.Message
ObjectDeviceId: uuid.NewV4().String(),
Name: "Fist send message to platform",
Id: uuid.NewV4().String(),
Content: "Hello Huawei IoT Platform",
device.SendMessage(message)
time.Sleep(2 * time.Minute)
设备属性
1、首先,在华为云IoT平台创建一个设备,并在该设备下创建3个子设备,设备及子设备的信息如下:
设备ID:5fdb75cccbfe2f02ce81d4bf_go-mqtt
设备密钥:123456789
子设备ID:5fdb75cccbfe2f02ce81d4bf_sub-device-1
子设备ID:5fdb75cccbfe2f02ce81d4bf_sub-device-2
子设备ID:5fdb75cccbfe2f02ce81d4bf_sub-device-3
2、使用SDK创建一个Device对象,并初始化Device。
// 创建设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")
device.Init()
fmt.Printf("device connected: %v\\n", device.IsConnected())
设备属性上报
使用ReportProperties(properties ServiceProperty) bool
上报设备属性
// 设备上报属性
props := iot.ServicePropertyEntry
ServiceId: "value",
EventTime: iot.DataCollectionTime(),
Properties: DemoProperties
Value: "chen tong",
MsgType: "23",
,
var content []iot.ServicePropertyEntry
content = append(content, props)
services := iot.ServiceProperty
Services: content,
device.ReportProperties(services)
网关批量设备属性上报
使用BatchReportSubDevicesProperties(service DevicesService)
实现网关批量设备属性上报
// 批量上报子设备属性
subDevice1 := iot.DeviceService
DeviceId: "5fdb75cccbfe2f02ce81d4bf_sub-device-1",
Services: content,
subDevice2 := iot.DeviceService
DeviceId: "5fdb75cccbfe2f02ce81d4bf_sub-device-2",
Services: content,
subDevice3 := iot.DeviceService
DeviceId: "5fdb75cccbfe2f02ce81d4bf_sub-device-3",
Services: content,
var devices []iot.DeviceService
devices = append(devices, subDevice1, subDevice2, subDevice3)
device.BatchReportSubDevicesProperties(iot.DevicesService
Devices: devices,
)
平台设置设备属性
使用AddPropertiesSetHandler(handler DevicePropertiesSetHandler)
注册平台设置设备属性handler,当接收到平台的命令时SDK回调。
// 注册平台设置属性callback,当应用通过API设置设备属性时,会调用此callback,支持注册多个callback
device.AddPropertiesSetHandler(func(propertiesSetRequest iot.DevicePropertyDownRequest) bool
fmt.Println("I get property set command")
fmt.Printf("request is %s", iot.Interface2JsonString(propertiesSetRequest))
return true
)
平台查询设备属性
使用SetPropertyQueryHandler(handler DevicePropertyQueryHandler)
注册平台查询设备属性handler,当接收到平台的查询请求时SDK回调。
// 注册平台查询设备属性callback,当平台查询设备属性时此callback被调用,仅支持设置一个callback
device.SetPropertyQueryHandler(func(query iot.DevicePropertyQueryRequest) iot.ServicePropertyEntry
return iot.ServicePropertyEntry
ServiceId: "value",
Properties: DemoProperties
Value: "QUERY RESPONSE",
MsgType: "query property",
,
EventTime: "2020-12-19 02:23:24",
)
设备侧获取平台的设备影子数据
使用QueryDeviceShadow(query DevicePropertyQueryRequest, handler DevicePropertyQueryResponseHandler)
可以查询平台的设备影子数据,当接收到平台的响应后SDK自动回调DevicePropertyQueryResponseHandler
。
// 设备查询设备影子数据
device.QueryDeviceShadow(iot.DevicePropertyQueryRequest
ServiceId: "value",
, func(response iot.DevicePropertyQueryResponse)
fmt.Printf("query device shadow success.\\n,device shadow data is %s\\n", iot.Interface2JsonString(response))
)
完整样例
import (
"fmt"
iot "github.com/ctlove0523/huaweicloud-iot-device-sdk-go"
"time"
)
func main()
// 创建设备并初始化
device := iot.CreateIotDevice("5fdb75cccbfe2f02ce81d4bf_go-mqtt", "123456789", "tcp://iot-mqtts.cn-north-4.myhuaweicloud.com:1883")

// 注册平台查询设备属性callback,当平台查询设备属性时此callback被调用,仅支持设置一个callback
device.SetPropertyQueryHandler(func(query iot.DevicePropertyQueryRequest) iot.ServicePropertyEntry
return iot.ServicePropertyEntry
ServiceId: "value",
Properties: DemoProperties
Value: "QUERY RESPONSE",
MsgType: "query property",
,
EventTime: "2020-12-19 02:23:24",
)
// 设备上报属性
