1. Demand

When we are developing a website, in many cases the login page can use a mobile phone number to receive a text message verification code and then log in. Let's do this function today.

pseudocode:

Enter the login page, click SMS login, enter the mobile phone number, click Get verification code, the backend saves the verification code in redis. The user enters the verification code received on the mobile phone, clicks Login, and the mobile phone number and verification code will be sent to the backend for verification.

In order to send text messages and let users receive text messages, we use the RongCloud interface to register an account.

Some parameters required for use:

Download SDK

1. . . . . . .

2. . . . . .

3. . . . . . .

After downloading, unzip it. Put it in libs in apps of our drf project

2. SDK parameter configuration

1. Directory structure

2. Configure the sms.py file

3. Code Implementation

1. Backend code

views.py, this is the processing of obtaining verification code requests, that is, the backend generates a random code, sends it to the mobile phone user, then stores the random code in redis, and then returns a verification code sending success signal to the front end

from .models import User
from rest_framework import status
from lufei_drf.libs.yuntongxun.sms import CCP
from django_redis import get_redis_connection
class SMSCodeAPIView(APIView):
    def get(self, request):
        # 1. Get the phone number through the query string phone = request.query_params.get("phone")
        ty = request.query_params.get('type')
        # 2. Verify the mobile number with the verification code before sending the SMS if ty=='register':
            try:
                User.objects.get(phone=phone)
                return Response({"message": "The current phone number has been registered"}, status=status.HTTP_400_BAD_REQUEST)
            except:
                pass
        redis = get_redis_connection("sms_code")
        if redis.get("times_%s" % phone):
            return Response({"message": "The current phone number has sent a text message within one minute"}, status=status.HTTP_400_BAD_REQUEST)

        # 3. Use the mobile phone number to send a text message verification code# Generate a text message verification code sms_code = "%04d" % random.randint(0, 9999)
        ccp = CCP()
        result = ccp.send_template_sms(phone,[sms_code,"5 minutes"],1)

        if result == 0:
            #Send SMS successfully, save SMS verification code to redis database#Open pipeline operation pl = redis.pipeline()
            pl.multi() # Next, multiple commands will be executed in the pipeline # setex(variable name, validity period [seconds], value)
            SMS_EXPIRE_TIME = 5 * 60 # The validity period of the SMS verification code SMS_TIMES = 60 # The interval between SMS sending # Put the original immediately executed command into the pipeline pl.setex("sms_%s" % phone, SMS_EXPIRE_TIME, sms_code)
            pl.setex("times_%s" % phone, SMS_TIMES, 1)

            # Unify the execution of commands in the pipeline pl.execute()

        # 4. Response data to the client return Response({"message":result},status=status.HTTP_200_OK)

urls.py

from django.urls import path
# Login view implemented internally by jwt from rest_framework_jwt.views import obtain_jwt_token
from .views import SMSCodeAPIView,

urlpatterns=[
    path(r"login/", obtain_jwt_token ),
    path('sms/', SMSCodeAPIView.as_view()),
]

utils.py, this is to check the mobile phone number and verification code after the user submits the mobile phone verification code. After all the judgments are correct, an object is returned, including token, user information, etc.

from django.contrib.auth.backends import ModelBackend
from django_redis import get_redis_connection

        'id': user.id,
        'username': user.username,
    }

    except User.DoesNotExist:
        return None
    else:
        return user
#Verify whether the SMS message submitted by the user is consistent with the information we saved in redis def sms_code_verify(phone, sms_code):
    redis = get_redis_connection("sms_code")
    value=redis.get('sms_%s'%phone).decode()
    if value==sms_code:
        return True
    return False

class UsernameMobileAuthBackend(ModelBackend):
    """
    Customize username or phone number authentication"""
    def authenticate(self, request, username=None, password=None, **kwargs):
        user = get_user_by_account(username) #When the password length is 4, I judge it to be a mobile phone number and SMS verification code login if len(password)==4 and user is not None and sms_code_verify(username,password):
            return user
        elif user is not None and user.check_password(password):
            return user
        else:
