aliyunIoT.py代码

很抱歉，我不知道您需要的是哪个 `aliyunIoT.py` 代码，因为可能有多个版本或多个用途的代码。不过，如果您需要使用阿里云物联网平台，可以参考以下步骤进行设备连接和数据通信：

1. 在阿里云物联网平台上创建产品和设备
2. 下载设备证书和密钥
3. 安装阿里云物联网Python SDK
4. 使用Python SDK连接物联网平台并发送数据

下面是一个示例代码，可以作为参考：

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.auth.credentials import StsTokenCredential
from aliyunsdkiot.request.v20180120.PubRequest import PubRequest

# 阿里云物联网平台参数
access_key_id = "your_access_key_id"
access_key_secret = "your_access_key_secret"
endpoint = "your_endpoint"
product_key = "your_product_key"
device_name = "your_device_name"
region_id = "cn-shanghai"
iot_topic = "/{}/{}/user/update".format(product_key, device_name)

# 设备证书和密钥
cert_file = "path/to/cert.pem"
key_file = "path/to/private.key"
ca_cert = "path/to/root.crt"

# 获取临时访问令牌
sts_access_key_id = "your_sts_access_key_id"
sts_access_key_secret = "your_sts_access_key_secret"
sts_security_token = "your_sts_security_token"

# 创建阿里云物联网SDK客户端
credential = StsTokenCredential(sts_access_key_id, sts_access_key_secret, sts_security_token)
client = AcsClient(access_key_id, access_key_secret, region_id, credential)

# 发送数据到物联网平台
def send_data_to_iot_platform(data):
    pub_request = PubRequest()
    pub_request.set_ProductKey(product_key)
    pub_request.set_TopicFullName(iot_topic)
    pub_request.set_MessageContent(data)
    pub_request.set_Qos(0)
    pub_request.set_AccessToken("")
    pub_request.set_Retain(0)
    pub_request.set_InstanceId("")
    pub_request.set_SignMethod("HmacSHA256")

    response = client.do_action_with_exception(pub_request)
    print(response)

# 连接设备并发送数据
if __name__ == "__main__":
    from paho.mqtt import client as mqtt

    mqtt_client = mqtt.Client(client_id=device_name, protocol=mqtt.MQTTv311)

    mqtt_client.tls_set(ca_certs=ca_cert, certfile=cert_file, keyfile=key_file)
    mqtt_client.tls_insecure_set(True)

    mqtt_client.username_pw_set("{}/{}/{}".format(access_key_id, device_name, access_key_secret))

    mqtt_client.connect(endpoint, port=1883)

    data = "hello world"
    send_data_to_iot_platform(data)

    mqtt_client.disconnect()

请注意，上述示例代码仅供参考，具体的实现方式可能因不同的设备类型、协议版本和应用场景而异。
