pymongo操作

Question

我从我的MongoDB中得到了很多记录，在这个过程中我得到了一个错误

File "C:\database\models\mongodb.py", line 228, in __iter__
    for result in self.results:
  File "C:\Python27\Lib\site-packages\pymongo\cursor.py", line 814, in next
    if len(self.__data) or self._refresh():
  File "C:\Python27\Lib\site-packages\pymongo\cursor.py", line 776, in _refresh
    limit, self.__id))
  File "C:\Python27\Lib\site-packages\pymongo\cursor.py", line 720, in __send_message
    self.__uuid_subtype)
  File "C:\Python27\Lib\site-packages\pymongo\helpers.py", line 99, in _unpack_response
    cursor_id)

pymongo.errors.OperationFailure: cursor id '866472135294727793' not valid at server
Exception KeyError: KeyError(38556896,) in <module 'threading' from 'C:\Python27\lib\threading.pyc'> ignored

这是什么意思？我该怎么解决它。我不知道这是否重要，但我知道 打开连接时使用from gevent import monkey; monkey.patch_all()

Answer 1

当光标长时间处于打开状态而没有对其进行操作时，它（光标）可能会超时->；这会导致错误

可以在find查询中设置timeout=False以关闭超时
