如何访问(询问)用户登录令牌

Question

我已经将Django Rest框架用于Rest，使用django-oauth工具包进行基于令牌的身份验证。我已经为用户注册设计了api。注册用户时，生成一个令牌并将其保存到数据库中。我要用户从那个令牌登录。我指的是基于令牌的身份验证，因为我想开发一个移动应用程序。在发送登录请求时，我可以使用curl获得access_token，但是如何实现视图，以便应用程序向127.0.0.1:8000/o/令牌发送post请求，请求令牌，以便请求包含用户名、密码、client_id和client_secret。然后，服务器接收凭据，如果它们有效，则返回access_token。其余的时间，它应该使用这个令牌来查询服务器。

views.py

class UserLoginAPI(APIView):
    permission_classes = [AllowAny]
    serializer_class = UserLoginSerializer

    def post(self, request, *args, **kwargs):
        access_token = AccessToken.objects.get(token=request.POST.get('access_token'), expires__gt=timezone.now()) # error is shown here. I get None
        data = request.data
        serializer = UserLoginSerializer(data=data)
        if serializer.is_valid(raise_exception=True):
            new_data = serializer.data
            return Response(new_data, status=status.HTTP_200_OK)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

serializers.py

class UserCreateSerializer(ModelSerializer):
    class Meta:
        model = User
        extra_kwargs = {"password": {"write_only": True}}

    def create(self, validated_data):
        username = validated_data['username']
        first_name = validated_data['first_name']
        last_name = validated_data['last_name']
        email = validated_data['email']
        password = validated_data['password']
        confirm_password = validated_data['password']
        user_obj = User(
                username = username,
                first_name = first_name,
                last_name = last_name,
                email = email
            )
        user_obj.set_password(password)
        user_obj.save()
        if user_obj:
            expire_seconds = oauth2_settings.user_settings['ACCESS_TOKEN_EXPIRE_SECONDS']
            scopes = oauth2_settings.user_settings['SCOPES']

            application = Application.objects.get(name="Foodie")
            expires = datetime.now() + timedelta(seconds=expire_seconds)
            access_token = AccessToken.objects.create(user=user_obj, 
                                                    application=application,
                                                    token = generate_token(),
                                                    expires=expires, 
                                                    scope=scopes)
        return validated_data


class UserLoginSerializer(ModelSerializer):
    # token = CharField(allow_blank=True, read_only=True)
    username = CharField()
    class Meta:
        model = User
        fields = [
            'username',
            'password',
            # 'token',

        ]
        extra_kwargs = {"password":
                            {"write_only": True}
                            }

因此，如果您希望api获得令牌，则取决于用户名和密码，如下所示：

def get_token(request):
    username = request.POST.get("username")
    password = request.POST.get("password")
    .... # other parameters
    try:
        user = User.objects.get(username=username, password=password)
    except ObjectDoesNotExist:
        return HttpResponse("Can't find this user")
    else:
        try:
            access_token = AccessToken.objects.get(user=user)
        except ObjectDoesNotExist:
            return HttpResponse("Haven't set any token")
        else:
            return HttpResponse(access_token)

如果要使用DRF处理此问题，请执行以下操作：

@api_view(['POST'])
def get_token(request):
    # get token by query just like above
    serializer = TokenSerializer(data=access_token.token) #you can pass more parameters to data if you want, but you also have to edit your TokenSerializer
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

你的TokenSerializer：

class TokenSerializer(ModelSerializer):
    class Meta:
        model = AccessToken
        field = (token,)

那得看情况

• Web上，您可以在cookie中发布您的用户名和密码来登录api，您的浏览器存储会话。
• 移动，您发布您的用户名和密码登录api，服务器响应令牌，然后您将它存储在您的手机，也许是密钥链，当您正在开发IOS app.And发送它作为http报头时，您想访问服务器，how-can-i-get-all-the-request-headers-in-django。
