编写注册接口

1 user/urls.py中添加路由

urlpatterns = [

　　　　path('register/', views.RegisterView.as_view()),# 注册视图, /user/register/

]

2 user/views.py 中写注册视图函数

import datetime
import random
from django.http import HttpResponse
from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import viewsets
from rest_framework.authentication import BasicAuthentication, SessionAuthentication
from rest_framework.filters import OrderingFilter
from rest_framework.decorators import action
from rest_framework.permissions import AllowAny, IsAdminUser, IsAuthenticatedOrReadOnly, IsAuthenticated
from rest_framework.response import Response
from rest_framework.throttling import UserRateThrottle
from rest_framework.pagination import PageNumberPagination
from rest_framework.views import APIView
from rest_framework.permissions import BasePermission, SAFE_METHODS
from user.models import User
from user.serializers import UserSerializer, UserInfoSerializ




class RegisterView(APIView):
    permission_classes = (AllowAny,)
    def post(self,request):
        """
        接收邮箱和密码, 前端校验两遍一致性, 注册成功后返回成功, 然后用户自行登录获取token
        1. 随机用户名
        2. 生成用户
        3. 设置用户密码
        4. 保存用户
        :param request:
        :return:  {'code':0,'msg':'注册成功'}
        """
        email=request.data.get('email')
        password=request.data.get('password')
        if all([email,password]):
            pass
        else:
            return Response({'code':9999,'msg':'参数不全'})
        rand_name=self.randomUsername()
        user=User(username=rand_name,email=email)
        user.set_password(password)
        user.save()
        return Response({'code':0,'msg':'注册成功'})
    def randomUsername(self):
        d=datetime.datetime.now()
        base='SYL'
        time_str = '%04d%02d%02d%02d%02d' % (d.year, d.month, d.day, d.hour, d.minute)
        rand_num = str(random.randint(10000, 99999))
        return base + time_str + rand_num

 

 

2 重写Django认证

2.1 syl/settings.py 中指定自定义后端认证函数位置

#自定义验证后端

AUTHENTICATION_BACKENDS = ['user.utils.EmailAuthBackend']

2.2user/utils.py 中重新认证函数

#以前使用username进行用户验证，现在改成email进行验证

from .models import User


class EmailAuthBackend:
    def authenticate(self,request,username=None,password=None):
        try:
            user=User.objects.get(username=username)

        except Exception as e:
            user=None
        if not user:
            try:
                user=User.objects.get(email=username)
            except Exception as e:
                user=None
        if user and user.check_password(password):
            return user
        else:
            return None

    def get_user(self,user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None
