手机号与验证码

• 简单验证码生成

def generate_code(self):
        """
        生成四位数字的验证码
        """
        seeds = "1234567890"
        random_str = []
        for i in range(4):
            random_str.append(choice(seeds))

        return "".join(random_str)

• setting.py中

# 手机号码正则表达式
REGEX_MOBILE = "^1[358]\d{9}$|^147\d{8}$|^176\d{8}$"

• users/serializers.py:
  验证手机号
