如何使用Python发送设备twin的动态报告属性
我想定期更新物联网设备所需的属性。我正在发送的所需属性如下:如何使用Python发送设备twin的动态报告属性,python,azure-iot-hub,Python,Azure Iot Hub,我想定期更新物联网设备所需的属性。我正在发送的所需属性如下: desired = { "para1" : {"time": [11,22,33]}, "para2" : {"site":"demo.com"} } 根据文档,以下是在设备内运行的脚本 import time import threading from azure.iot.device import IoTHubMo
desired = {
"para1" : {"time": [11,22,33]},
"para2" : {"site":"demo.com"}
}
根据文档,以下是在设备内运行的脚本
import time
import threading
from azure.iot.device import IoTHubModuleClient
CONNECTION_STRING = "IOTHUB Device Connection String"
def twin_update_listener(client):
while True:
patch = client.receive_twin_desired_properties_patch() # blocking call
print("Twin patch received:")
print(patch)
def iothub_client_init():
client = IoTHubModuleClient.create_from_connection_string(CONNECTION_STRING)
return client
def iothub_client_sample_run():
try:
client = iothub_client_init()
twin_update_listener_thread = threading.Thread(target=twin_update_listener, args=(client,))
twin_update_listener_thread.daemon = True
twin_update_listener_thread.start()
# Send reported
print ( "Sending data as reported property..." )
reported_patch = {"connectivity": "cellular"}
client.patch_twin_reported_properties(reported_patch)
print ( "Reported properties updated" )
while True:
time.sleep(1000000)
except KeyboardInterrupt:
print ( "IoT Hub Device Twin device sample stopped" )
if __name__ == '__main__':
print ( "Starting the Python IoT Hub Device Twin device sample..." )
print ( "IoTHubModuleClient waiting for commands, press Ctrl-C to exit" )
iothub_client_sample_run()
在这里,它将报告的_属性更新为静态值(报告的_补丁={“连接性”:“蜂窝”})
,但我希望上传与所需值相同的报告值:
{
"para1" : {"time": [11,22,33]},
"para2" : {"site":"demo.com"}
}
请告诉我如何实现此目标。尝试此操作,将
所需的值上载到报告的一次所需的值更改:
import time
import threading
from azure.iot.device import IoTHubModuleClient
CONNECTION_STRING = ""
def twin_update_listener(client):
while True:
patch = client.receive_twin_desired_properties_patch() # blocking call
print("Twin patch received")
patch.pop('$version',None)
print ( "Sending Twin as reported property..." )
print(patch)
client.patch_twin_reported_properties(patch)
print ( "Reported properties updated" )
def iothub_client_init():
client = IoTHubModuleClient.create_from_connection_string(CONNECTION_STRING)
return client
def iothub_client_sample_run():
try:
client = iothub_client_init()
twin_update_listener_thread = threading.Thread(target=twin_update_listener, args=(client,))
twin_update_listener_thread.daemon = True
twin_update_listener_thread.start()
while True:
time.sleep(1000)
except KeyboardInterrupt:
print ( "IoT Hub Device Twin device sample stopped" )
if __name__ == '__main__':
print ( "Starting the Python IoT Hub Device Twin device sample..." )
print ( "IoTHubModuleClient waiting for commands, press Ctrl-C to exit" )
iothub_client_sample_run()
那么,您想上载与之前上载的所需值具有相同值的报告的\u属性吗?是的,我希望报告的值具有与所需值完全相同的数据非常感谢Stanley,它现在工作正常。@vishruti,很高兴为您提供帮助:)
