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):
    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']

2.2 user/utils.py 中重写认证函数

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

http://192.168.56.100:8888/user/register/

3.2 登录接口测试

注： 认证时只能识别username，所以必须要在请求中携带username字段 

http://192.168.56.100:8888/user/login/

3.3 获取用户列表接口测试 

访问接口
http://192.168.56.100:8888/user/user/5/

# 自定义权限类 
permission_classes = (MyPermission,) 
# 自定义认证类, 自定义会覆盖全局配置 
authentication_classes = (JSONWebTokenAuthentication,)
