JWT 简单编写注册接口

1.1 user/urls.py 中添加路由

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

1.2 user/views.py 中写注册视图函数

class RegisterView(APIView):
    """
    用户注册, 权限是: 匿名用户可访问
    """
    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':999,'msg':"canshubuquan"})

        rand_name=self.randomUsername()
        user=User(username=rand_name,email=email)
        user.set_password(password)
        user.save()

        return Response({'code':'0','msg':"sucessful"})
    def randomUsername(self):
        """ 生成随机用户名: 格式: SYL + 年月日时分 + 5位随机数 :return: """
        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']

2.2 user/utils.py 中重写认证函数

# -*- coding: utf-8 -*-
from user.models import *
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

3.注册用户
