介绍

用户注册API的主要流程：1.前端用户提交用户名，密码 2. 序列化器校验用户名，密码是否合法。3.存入数据库。4.签发token

创建序列化器

from rest_framework import serializers
from rest_framework_simplejwt.serializers import TokenObtainPairSerializer
from userauth.models import User
from systemauth.models import UserRole

# 用户注册序列胡器
class RegisterSerializer(serializers.Serializer):
    """
    注册用户信息序列化校验
    """
    username = serializers.CharField()
    password = serializers.CharField()

    def validate(self, attrs):
        username = attrs.get('username')
        password = attrs.get('password')
        if User.objects.filter(username=username).exists():
            raise serializers.ValidationError('用户名已被占用')
        print(password)
        if not password or len(password) < 6:
            raise serializers.ValidationError("密码不符合要求，请使用6位以上密码")

        if attrs.get("is_vip"):
            attrs['is_vip'] = False
       	attrs['is_active'] = True
        # 将用户信息保存到数据库中
        user = User.objects.create(**attrs)
        # 为其设置角色为普通用户
        UserRole.objects.create(**{'user_id': user.id, 'role_id': 2})
        if user:
            # 签发token
            '签发token'
            refresh = TokenObtainPairSerializer.get_token(user)

            data = {
                'code': 100,
                'message': '登录成功',
                'username': user.username,
                'refresh': str(refresh),
                'access': str(refresh.access_token),
            }
            return data
        else:
            raise serializers.ValidationError('用户注册失败')

view视图

from userauth.serializers import RegisterSerializer
from rest_framework.generics import GenericAPIView
class UserRegisterView(GenericAPIView):
    # 注册接口，局部禁用用户验证和权限
    authentication_classes = ()
    permission_classes = ()
    serializer_class = RegisterSerializer
    def post(self, request, *args, **kwargs):
        res = self.get_serializer(data=request.data)
        res.is_valid(raise_exception=True)
        data = res.validated_data
        return Response({'msg': data})
