Python 正在使用restapi将部分图像上载到parse.com

当我试图通过以下python脚本使用restapi将图像上载到parse.com时，只上载了部分图像

我得到了以下json响应

{“url”：“名称”：“tfss-08a78f3e-d95c-48be-b64f-2c564d310e38-pdr11.jpg”}

当我试图打开url作为回应时，只上传了部分2kb的图像

图像的实际大小为553kb

view.py

def index(request):
    connection = httplib.HTTPSConnection('api.parse.com', 443)
    connection.connect()
    querySetList = Post.objects.all()
    imageToUpload = open("D:\\Beautiful-Android-cell-phone-wallpapers-480x854-06.jpg","rb")
    #print imageToUpload.name

    connection.request('POST', '/1/files/pdr11.jpg', open(str(imageToUpload.name), 'r+').read(), {
       "X-Parse-Application-Id": "NMVvDdhhWfvs6tBcxTSta7RZWVn47TqpJsrXkboh",
       "X-Parse-REST-API-Key": "G5flmDwYy44tdVPoR3q5eBbjaIREVew5hKWqMr7S",
       "Content-Type": "image/jpeg"
     })
    result1 = json.loads(connection.getresponse().read())

    return HttpResponse(json.dumps(result1),content_type='application/json')
