How to use Python to develop the SMS verification code function of the CMS system

With the development of the mobile Internet, the importance of the SMS verification code function in various applications has become increasingly prominent. For CMS systems, SMS verification codes are a common user verification method. This article will introduce in detail how to use Python to develop the SMS verification code function of the CMS system and provide corresponding code examples.

1. Determine the SMS service provider

Before developing the SMS verification code function, you first need to choose a reliable SMS service provider. Commonly used SMS service providers in China include Alibaba Cloud, Tencent Cloud, etc., which provide rich API interfaces. This article takes Alibaba Cloud as an example, and the specific code examples will also be based on Alibaba Cloud's API interface.

2. Install dependent libraries

In the Python development environment, we need to install the corresponding dependent libraries to implement the SMS verification code function. These libraries can be easily installed using the pip command. The specific dependent libraries are as follows:

pip install aliyun-python-sdk-core
pip install aliyun-python-sdk-dysmsapi

3. Get SMS template

In the Alibaba Cloud console, we need to create an SMS template first. The SMS template is a template for the content sent by SMS, in which variables can be inserted as needed, such as verification codes, etc. When creating an SMS template, you need to pay attention to the audit status of the template. It can be used normally only after it passes the audit.

4. Write code to send SMS

The following is a simple Python code example for sending SMS verification code:

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.request import CommonRequest

def send_sms(phone_number, sms_code):
    access_key = 'YOUR_ACCESS_KEY'  # 阿里云账号的Access Key
    access_secret = 'YOUR_ACCESS_SECRET'  # 阿里云账号的Access Secret

    # 创建AcsClient实例
    client = AcsClient(access_key, access_secret, 'cn-hangzhou')

    # 创建发送短信的请求对象
    request = CommonRequest()
    request.set_method('POST')
    request.set_protocol_type('https')
    request.set_domain('dysmsapi.aliyuncs.com')
    request.set_version('2017-05-25')
    request.set_action_name('SendSms')

    # 设置发送短信的参数
    request.add_query_param('PhoneNumbers', phone_number)
    request.add_query_param('SignName', 'YOUR_SIGN_NAME')  # 短信签名
    request.add_query_param('TemplateCode', 'YOUR_TEMPLATE_CODE')  # 短信模板CODE
    request.add_query_param('TemplateParam', f'{{"code":"{sms_code}"}}')

    # 发送短信
    response = client.do_action_with_exception(request)
    print(response.decode('utf-8'))

In the above code, We need to replace access_key and access_secret with the Access Key and Access Secret of our Alibaba Cloud account. In addition, SignName needs to be replaced with your own SMS signature, and TemplateCode needs to be replaced with your own SMS template CODE.

5. Improve verification code generation and verification logic

In addition to sending SMS verification codes, we also need to write verification code generation and verification logic. The verification code can be generated using random numbers and is generally 4 to 6 digits in length. Before sending the SMS verification code, the verification code needs to be stored on the server side for verification.

The following is a simple code example for generating and verifying SMS verification codes:

import random
import string

def generate_sms_code(length=6):
    # 生成指定长度的验证码
    code_pool = string.digits  # 验证码字符池，此处使用数字
    code = ''.join(random.choices(code_pool, k=length))
    return code

# 验证短信验证码是否正确
def verify_sms_code(stored_code, input_code):
    return stored_code == input_code

In the above code, the generate_sms_code function is used to generate SMS messages of specified length Verification code, verify_sms_code function is used to verify whether the verification code entered by the user is consistent with the verification code stored on the server side.

Through the above steps, we have completed how to use Python to develop the SMS verification code function of the CMS system. By calling the SMS service provider's API interface, we can easily implement the sending and verification functions of SMS verification codes. This improves the security and user experience of our CMS system.
