“ OSError：[Errno 24]打开的文件太多：”和来自aiocoap context.

Question

您好，我正在研究树莓派PI，它应该从连接到该PI的传感器连续发送数据，所以这是我的脚本：import loggingimport asynciofrom grovepi import*import timeimport jsonfrom aiocoap import *logging.basicConfig(level=logging.INFO)def createMsg( file,value ) :    f= open(file + "Config.json")    data = json.load(f)    f.close()    data["timestamp"] = str(round(time.time(), 3))    data["value"] = value    return json.dumps( data )async def main():    #analog    soundSensorPort=0    lightSensorPort=1    #digital    motionSensorPort=2    tempSensorPort=2    ultrasonicSensorPort=5    pinMode(tempSensorPort, "INPUT")    while True:        context = await Context.create_client_context()        await asyncio.sleep(2)        [ tempSensorValue, humiditySensorValue ]  = dht(tempSensorPort, 0)        tempMsg = createMsg( "temperatureSensor", tempSensorValue)        humidityMsg = createMsg( "humiditySensor", humiditySensorValue)        payloadTemp = tempMsg.encode('utf-8')        payloadHumidity = humidityMsg.encode('utf-8')        requestTemp = Message(code=PUT, payload=payloadTemp)        requestHumidity = Message(code=PUT, payload=payloadHumidity)        requestTemp.opt.uri_host = '129.6.60.38'        requestHumidity.opt.uri_host = '129.6.60.38'        requestTemp.opt.uri_path = ("other", "sensors","temperature")        requestHumidity.opt.uri_path = ("other", "sensors","humidity")        responseTemp = await context.request(requestTemp).response        responseHumidity = await context.request(requestHumidity).response        print('Result: %s\n%r'%(responseTemp.code, responseTemp.payload))        print('Result: %s\n%r'%(responseHumidity.code, responseHumidity.payload))if __name__ == "__main__":    asyncio.get_event_loop().run_until_complete(main())这真的很奇怪，因为我只是在读取文件并将其加载到“ f”之后关闭了文件，所以如果有人有想法，这将非常有帮助
