DRF实现发送短信验证码接口

一、settings.py

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

二、users下新建serializers.py,代码如下：

# users/serializers.py

import re
from datetime import datetime, timedelta
from MxShop.settings import REGEX_MOBILE
from users.models import VerifyCode
from rest_framework import serializers
from django.contrib.auth import get_user_model
User = get_user_model()


class SmsSerializer(serializers.Serializer):
    mobile = serializers.CharField(max_length=11)
    
    #函数名必须：validate + 验证字段名
    def validate_mobile(self, mobile):
        """
        手机号码验证
        """
        # 是否已经注册
        if User.objects.filter(mobile=mobile).count():
            raise serializers.ValidationError("用户已经存在")

        # 是否合法
        if not re.match(REGEX_MOBILE, mobile):
            raise serializers.ValidationError("手机号码非法")

        # 验证码发送频率
        #60s内只能发送一次
        one_mintes_ago = datetime.now() - timedelta(hours=0, minutes=1, seconds=0)
        if VerifyCode.objects.filter(add_time__gt=one_mintes_ago, mobile=mobile).count():
            raise serializers.ValidationError("距离上一次发送未超过60s")

        return mobile

三、APIKEY加到settings里面

#云片网APIKEY
APIKEY = "xxxxx327d4be01608xxxxxxxxxx"

四、views后台逻辑

我们要重写CreateModelMixin的create方法，下面是源码：

class CreateModelMixin(object):
    """
    Create a model instance.
    """
    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

    def perform_create(self, serializer):
        serializer.save()

    def get_success_headers(self, data):
        try:
            return {'Location': str(data[api_settings.URL_FIELD_NAME])}
        except (TypeError, KeyError):
            return {}

需要加上自己的逻辑

users/views.py 

from rest_framework.mixins import CreateModelMixin
from rest_framework import viewsets
from .serializers import SmsSerializer
from rest_framework.response import Response
from rest_framework import status
from utils.yunpian import YunPian
from MxShop.settings import APIKEY
from random import choice
from .models import VerifyCode


class SmsCodeViewset(CreateModelMixin,viewsets.GenericViewSet):
    '''
    手机验证码
    '''
    serializer_class = SmsSerializer

    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)

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        #验证合法
        serializer.is_valid(raise_exception=True)

        mobile = serializer.validated_data["mobile"]

        yun_pian = YunPian(APIKEY)
        #生成验证码
        code = self.generate_code()

        sms_status = yun_pian.send_sms(code=code, mobile=mobile)

        if sms_status["code"] != 0:
            return Response({
                "mobile": sms_status["msg"]
            }, status=status.HTTP_400_BAD_REQUEST)
        else:
            code_record = VerifyCode(code=code, mobile=mobile)
            code_record.save()
            return Response({
                "mobile": mobile
            }, status=status.HTTP_201_CREATED)

五、配置url

from users.views import SmsCodeViewset

# 配置codes的url
router.register(r'code', SmsCodeViewset, base_name="code")
