阿里物联网平台（一）Windows系统+VS2017 模拟设备端接入

https://blog.csdn.net/panwen1111/article/details/88365636

一、阿里物联网平台

平台地址：https://account.aliyun.com

根据文档设置平台端，跟着文档一步步来

文档地址：https://help.aliyun.com/document_detail/42648.html?spm=a2c4g.11174283.6.642.78b01668rFZaSZ

二、Windows模拟设备端

1.安装vs2017开发工具，配置好Python环境

使用pip来安装linkkit最新版本

pip install aliyun-iot-linkkit
2.Python实现客户端与平台连接、发送消息、接收消息

参考文档：https://help.aliyun.com/document_detail/98292.html?spm=a2c4g.11186623.6.617.4ca226831rShZt

#断开连接回调

lk.on_connect = on_connect
lk.on_disconnect = on_disconnect

lk.config_device_info("Eth|03ACDEFF0032|Eth|03ACDEFF0031")

lk.connect_async()

#订阅云端消息
def on_subscribe_topic(mid, granted_qos, userdata):
print("on_subscribe_topic mid:%d, granted_qos:%s" %

#接收与处理来自云端的消息
def on_topic_message(topic, payload, qos, userdata):

time.sleep(5)

lk.on_publish_topic = on_publish_topic
lk.on_topic_message = on_topic_message
lk.on_subscribe_topic = on_subscribe_topic

#订阅云端消息,系统消息
#rc, mid = lk.subscribe_topic("/sys/a1hSxOQhke5/smp001/thing/service/property/set")

#订阅云端消息,自定义消息
rc, mid = lk.subscribe_topic(lk.to_full_topic("user/get"))

i=1

#阿里云系统参数上报数据，t1对应云平台属性名称
payload_json = {
'id': int(time.time()),
'params': {
't1': 88
},
'method': "thing.event.property.post"
}

#阿里云自定义参数上报数据
payload_json2 = {'params': {'t1': 123}}

while(True):

print(str(i))

#发送消息到云端，系统订阅上报
#rc, mid = lk.publish_topic("/sys/a1hSxOQhke5/smp001/thing/event/property/post", str(payload_json))

#发送消息到云端，自定义订阅上报
#rc, mid = lk.publish_topic(lk.to_full_topic("user/update"), str(payload_json2))

i = i + 1

time.sleep(15)
运行，连接成功，订阅成功！
