Question

尝试使用blobstore将图像上传到google app引擎项目时出现以下错误：

POST someindex/_search
{  
   "size":0,
   "aggs":{  
      "myagg":{  
         "terms":{  
            "script":{  
               "source":"doc['field1'].value + params.param + doc['field2'].value + params.param + doc['field3'].value",
               "lang":"painless",
               "params":{  
                  "param":", "
               }
            },
            "order":{  
               "_term":"asc"
            }
         }
      }
   }
}

我的代码如下：

ERROR    2018-10-29 11:18:21,519 user.py:476] ERROR is 'PicUploadHandler' 
object has no attribute '_BlobstoreUploadHandler__uploads'
ERROR    2018-10-29 11:18:21,519 user.py:477] EXC is 'PicUploadHandler' 
object has no attribute '_BlobstoreUploadHandler__uploads'
Traceback (most recent call last):
  File "C:\Users\...\PycharmProjects\...\user.py", line 460, in post
    upload_files = self.get_uploads()[0]  #: 'file' is file upload field in 
the form
  File "C:\Program Files(x86)\Google\google_appengine\google\appengine\ext\webapp\blobstore_handlers.py", line 380, in get_uploads
if self.__uploads is None:
AttributeError: 'PicUploadHandler' object has no attribute '_BlobstoreUploadHandler__uploads'

我已经从一个较旧的项目中复制并粘贴了此代码，该项目在其中没有错误地运行。

非常感谢您的帮助。

编辑：作为冰雹玛丽，我上传了代码，以便检查实时实例中的日志。看来问题出在开发服务器/数据存储上，因为该代码在应用在线时运行。有人知道为什么会这样吗？

尝试登录以查看所拥有的内容

import logging

user = self.user_obj()
if user:
    self.response.headers['Content-Type'] = 'image/svg+xml'
    if user.pic_key:
        blobstore.delete(user.pic_key)  #: retrieve the old home photo and delete it

    logging.error(self.get_uploads())
    logging.error(self.get_uploads()[0])
    upload_files = self.get_uploads()[0]  #: 'file' is file upload field in the form
    ...
