【问题描述】：
我想使用 python 连接到一个 mongo 实例，该实例与托管在 meteor.com 上的流星应用程序相关联。我已经通过meteor mongo -U <appname> 命令获得了我的应用程序的 URL，并且我能够连接。但是，当我连接并尝试做一些简单的事情（枚举“幻灯片”集合中的文档）时，我收到一个错误：
In [1]: import pymongo
In [2]: con = pymongo.Connection("mongodb://client:f066d336-f5bd-1a85-1039-c679fbb645a1@skybreak.member0.mongolayer.com:27017/slides_meteor_com").meteor
In [3]: con.slides.find()
Out[3]: <pymongo.cursor.Cursor at 0x109873690>
In [4]: [ x for x in con.slides.find() ]

据我所知，这是 mongo 建议我无权读取该集合。我可以通过 meteor mongo <projectname 从 mongo 控制台读取它，但不能从 python 读取。如何在 python 中读取它？
