13.短信验证码

1. 注册容联云账号

1.1 注册账号

https://www.yuntongxun.com/user/login

1.2 登录即可看到开发者账号信息

1.3 添加测试账号

2.使用容联云发送代码测试

\'\'\'1. 安装容联云sdk\'\'\'
pip install ronglian_sms_sdk
# 免费测试文档地址:https://doc.yuntongxun.com/p/5a531a353b8496dd00dcdfe2


\'\'\'2. 短信发送代码\'\'\'
# libs/rl_sms.py
from ronglian_sms_sdk import SmsSDK

accId = \'8a216da8747ac98201749c0de38723b7\'
accToken = \'86072b540b4648229b27400414150ef2\'
appId = \'8a216da8747ac98201749c0de45123be\'

def send_message(phone, datas):
    sdk = SmsSDK(accId, accToken, appId)
    tid = \'1\' # 测试模板id为: 1. 内容为: 【云通讯】您的验证码是{1}，请于{2}分钟内正确输入。
    # mobile = \'13303479527\'
    # datas = (\'666777\', \'5\') # 模板中的参数按照位置传递
    resp = sdk.sendMessage(tid, phone, datas)
    return resp

3. 在视图函数中使用

3.1 在verifications/urls.py中添加路由

urlpatterns = [
    path(\'sms_codes/\', views.SmsCodeView.as_view()),
]

3.2 写视图函数

# verifications/views.py
from rest_framework.permissions import AllowAny
from rest_framework.views import APIView
from rest_framework.response import Response
import re
import random
from utils.rl_sms import send_message


class SmsCodeView(APIView):
    # 所有人可以访问
	permission_classes = (AllowAny,)
    
    def post(self, request):
	# 1. 获取参数
        phone = request.data.get(\'phone\')
        image_code = request.data.get(\'image_code\')
        image_code_uuid = request.data.get(\'image_code_uuid\')
        
        # 2. 检查参数
        if not all([phone, image_code, image_code_uuid]):
	    return Response({"code": 999, "msg": "参数不全"})
	if not re.match(r\'^1[3456789]\d{9}$\', phone):
	    return Response({"code": 999, "msg": "手机号码不正确"})
        
        # 3. 检查是否发送
        redis_client = get_redis_connection(\'img_code\')
        phone_exists = redis_client.get(phone)
        if phone_exists:
            return Response({"code": 999, "msg": "频繁发送, 请稍后再试"})
        
        redis_image_code = redis_client.get(image_code_uuid) # bytes
        if redis_image_code:
            # bytes 转成 string
            redis_image_code = redis_image_code.decode()
        
        # 比较用户提供的图片内容是否和redis中保存的一致
        if image_code.upper() != redis_image_code:
            return Response({\'code\': 999, \'msg\': \'图片验证码不正确\'})
        
        # 4. 发送
        code = \'%06d\' % random.randint(0, 999999) # 随机6位验证码
        send_resp = send_message(phone, (code, "5"))
        
        # 5.1 保存code 到 redis中
	# redis_client.setex(phone, 60 * 5, code) # phone:code, 5分钟有效期
        
        # 5.2 从redis中删除这个图片验证码, 以防再次被使用
	# redis_client.delete(image_code_uuid)
        
        # 5.3 使用 pipeline 批量操作
        pl = redis_client.pipeline()
        pl.setex(phone, 60 * 5, code)
        pl.delete(image_code_uuid)
        pl.execute()
		
        # 6. 返回结果
	return Response({"code": 0, "msg": "短信发送成功"})
