Question

我有一个使用django-rest-framework的图片字段如何处理通过API上传图片的内容？

有没有例子？

models.py

image = models.ImageField(
        upload_to="profiles",
        height_field="height",
        width_field="width",
        null=True,
        blank=True,
        editable=True,
        help_text="Profile Picture",
        verbose_name="Profile Picture"
    )
    height = models.PositiveIntegerField(null=True, blank=True, editable=False)
    width = models.PositiveIntegerField(null=True, blank=True, editable=False)

最后，我可以使用Django上传图片。这是我的工作代码

views.py

class FileUploadView(APIView):
# parser_classes = (MultiPartParser, FormParser, )
parser_classes = (FileUploadParser, )

# media_type = 'multipart/form-data'
# format = 'jpg'

def post(self, request, format='jpg'):
    up_file = request.FILES['file']
    destination = open('/Users/Username/' + up_file.name, 'wb+')
    for chunk in up_file.chunks():
        destination.write(chunk)
        destination.close()

    # ...
    # do some stuff with uploaded file
    # ...
    return Response(up_file.name, status.HTTP_201_CREATED)

urls.py

urlpatterns = patterns('', 
url(r'^imageUpload', views.FileUploadView.as_view())

curl上传请求

curl -X POST -S -H -u "admin:password" -F "file=@img.jpg;type=image/jpg" 127.0.0.1:8000/resourceurl/imageUpload

Answer 2

图像字段不存储图像，而是存储图像的链接。你在设置中设置了MEDIA_URL吗？例如MEDIA_URL ='/ media /'如果你在localhost上运行，你应该在localhost / media / profiles / image_name.png找到图像

django-rest-framework和上传图片
