Django Rest Framework：无法序列化或保存上传的图像

Question

无法在 API 视图中序列化或保存上传的图像。如果保存，则文件已损坏且无法打开。如果序列化，得到： {"avatar":["No file was submitted."]} 请求内容：

MultiValueDict: {u'name': [<TemporaryUploadedFile: Avatar.jpg (image/jpeg)>]}

设置：

FILE_UPLOAD_HANDLERS = [
'django.core.files.uploadhandler.TemporaryFileUploadHandler',
]
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(PROJECT_DIR, 'media')

网址：

urlpatterns = [
url(r'^test/$', TestReturn.as_view(), name='test-detail'),
url(r'^users/$', UserProfileAll.as_view(), name='userprofile-detail'),
url(r'^avatar/', UploadAvatar.as_view(), name='images')

] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

型号：

class AvatarStorage(models.Model):
avatar = models.ImageField(verbose_name="Uploaded image", upload_to='media', null=True)

连载：

class AvatarStorageSerializer(serializers.ModelSerializer):
avatar = serializers.ImageField(use_url=True)

class Meta:
    model = AvatarStorage

    fields = '__all__'

观看次数：

class UploadAvatar(APIView):
parser_classes = (MultiPartParser,)

def post(self, request, format=None):

    serializer = AvatarStorageSerializer(data=request.data)
    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)

对于发布，我使用的是 Postman，在那里设置：Body=>Form-Data 并从磁盘中选择一个文件。

如果这很重要，这是 API 移动版

Answer 1

更新设置文件 FILE_UPLOAD_HANDLERS 以点赞

FILE_UPLOAD_HANDLERS=[
    'django.contrib.staticfiles.finders.MemoryFileUploadHandler',
    'django.contrib.staticfiles.finders.TemporaryFileUploadHandler',
]

Answer 2

问题不在代码中，我在 Postman 中缺少必需的 headers：

Content-Disposition: attachment; filename=upload.jpg;
