#models.py

class test(models.Model):
    ...
    upload_path = 'upload/'
    image = models.ImageField(upload_to=upload_path,null=True,blank=True)
    ...

#serializers.py

class TestSerializer(serializers.ModelSerializer):
    image = serializers.ImageField(
        max_length=None,use_url=True,)
    class Meta:
        model = test
        fields = ('id','name','image',...)

#views.py

@api_view(['GET','POST'])
def test_list(request,site_id,block_id):

            ....

        if request.method == 'POST':
            serializer = TestSerializer(data=request.DATA)
            if serializer.is_valid():
                serializer.save()
                return Response(serializer.data,status=status.HTTP_201_CREATED)
            else:
                return Response(
                    serializer.errors,status=status.HTTP_400_BAD_REQUEST)
    else :
        return Response(status=status.HTTP_403_FORBIDDEN)

#js

function setimage() {
    var $input = $("#js_teaser_img");
    var fd = new FormData;

    fd.append('image',$input.prop('files')[0]);

    $.ajax({
        url: '/api/....',data: fd,processData: false,contentType: false,type: 'POST',success: function (data) {
            alert(data);
        }
    });
}

结果图片：[“没有提交文件.”] 0：“没有提交文件.”

结果

Django REST Framework upload image: “The submitted data was not a file”

?

var reader = new FileReader();  
        reader.onload = function(e) {
            var img_local = e.target.result;
            $('.js_img_src').attr('src',img_local);
            $.post('/api/..../7/',{'image':img_local},function( data ) {
                console.log(data);
            });
        }
        reader.readAsDataURL(file);
