文件:“上传有效图像"；在Django Rest Framework中使用Postman [英] File : "Upload a valid image" using Postman in Django Rest Framework

问题描述

我正在使用Django Rest Framework上传个人资料图片，并使用Google Cloud Storage存储我的图片.我用Postman测试了我的API，结果如下:

对于多部分表单，您应该使用 MultiPartParser :Postman result And here is my Postman headers : Postman headers

This is my code :

class ProfilePictureSerializer(serializers.Serializer):
file = serializers.ImageField()

class UploadProfilePictureAPI(APIView):
permission_classes = (IsAuthenticated,)
parser_classes = [FileUploadParser]

@staticmethod
def post(request):
    input_serializer = serializers.ProfilePictureSerializer(
        data=request.data
    )
    input_serializer.is_valid(raise_exception=True)

    profile = ProfileService.upload_profile_picture(
        request.user,
        **input_serializer.validated_data
    )

    output_serializer = serializers.ProfileSerializer(profile)
    return Response(
        output_serializer.data,
        status=status.HTTP_202_ACCEPTED
    )

@staticmethod
def upload_profile_picture(user, file):
    user.profile.profile_picture = file
    user.profile.save()
    return user.profile

path(
    'upload/picture',
    views.UploadProfilePictureAPI.as_view(),
    name='api_upload_profile_picture'
),

I does not understand why I have this response. Could you help me ?

解决方案

I think the issue here might be that FileUploadParser expects you to just send raw binary data (you can see the binary option in Postman).

In your current example, can you just try to send the binary data like so?

For multipart form you should use the MultiPartParser: https://www.django-rest-framework.org/api-guide/parsers/#multipartparser
