编写注册接口

1.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 
    """ 
    # 自定义权限类
    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') 									passwrod=request.data.get('password') 
        if all([email, passwrod]):
            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(passwrod) 
        user.save() 
        return Response({'code': 0, 'msg': '注册成功'})
    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

# 以前使用username进行用户验证，现在修改成email进行验证
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 & 测试登录

3.1 注册接口测试

3.2 登录接口测试
