Use Python to interface with Tencent Cloud to implement the SMS verification code function

With the popularity and rapid development of mobile phones, SMS verification codes have become a common identity verification method and are widely used in various in web services and applications. This article will introduce how to use Python to interface with Tencent Cloud to implement the SMS verification code function.

First of all, we need to register an account on the Tencent Cloud official website and activate the SMS service. Then, we can use the SDK provided by Tencent Cloud for interface docking.

Step 1: Install SDK
First, we need to install Tencent Cloud SDK. You can use the pip command to install:

pip install qcloudsms_py

Step 2: Import the SDK library
In the Python script, import the required library files:

from qcloudsms_py import SmsSingleSender
from qcloudsms_py.httpclient import HTTPError

Step 3: Set up the Tencent Cloud SMS application appID and appKey
In the SMS application management of Tencent Cloud official website, you can find appID and appKey and set them as constants:

appid = 12345678  # 替换为真实的appid
appkey = "abcdefghi"  # 替换为真实的appkey

Step 4: Write a function to send SMS messages
We can define a function To send text messages, accept mobile phone number and verification code as parameters:

def send_sms(phone_number, verify_code):
    try:
        ssender = SmsSingleSender(appid, appkey)  # 创建SmsSingleSender对象
        template_id = 1234  # 替换为真实的短信模板ID
        sms_sign = "我的应用"  # 替换为真实的短信签名

        params = [verify_code]  # 短信模板中的参数，这里只有一个验证码

        result = ssender.send_with_param(86, phone_number, template_id, params, sign=sms_sign, extend="", ext="")
        # 86表示中国区号，替换为其他国家区号
        # phone_number为接收短信的手机号码
        # template_id为短信模板ID
        # params为模板中的参数列表
        # sign为短信签名
        # extend、ext为扩展字段，可填空

        if result['result'] == 0:
            print("短信发送成功")
        else:
            print("短信发送失败：" + result['errmsg'])
    except HTTPError as e:
        print("短信发送异常：" + str(e))
    except Exception as e:
        print("发送短信出现异常：" + str(e))

Step 5: Call the function to send text messages
Write a main function and call the send_sms function to test:

def main():
    phone_number = "13812345678"  # 替换为真实的手机号码
    verify_code = "123456"  # 替换为真实的验证码

    send_sms(phone_number, verify_code)

if __name__ == "__main__":
    main()

Now , we use the real mobile phone number and verification code to perform the call test, and then we can send text messages. Please note that the SMS template ID and SMS signature need to be set on the Tencent Cloud official website.

Summary:
This article introduces how to use Python to connect with the Tencent Cloud interface to implement the SMS verification code function. Install Tencent Cloud SDK, set appID and appKey, write a function to send text messages, and finally call the function to send text messages. In this way, we can easily integrate the SMS verification code function in our Python application to improve user security.
