破译连接到托管在 <project>.meteor.com 的 mongo 实例的错误 [英] Decipher an error connecting to a mongo instance hosted at <project>.meteor.com

问题描述

我想使用 python 连接到与在meteor.com 上托管的meteor 应用程序绑定的mongo 实例.我已经通过 meteor mongo -U 命令获得了我的应用程序的 URL，并且我能够连接.但是，当我建立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，出现错误:

I'd like to use python to connect to an instance of mongo tied to a meteor app hosted at meteor.com. I've gotten the URL for my app via the meteor mongo -U <appname> command, and I am able to connect. However, when I have gotten connected and try to do something simple (enumerate documents in the "slides" collection), I get an error:

In [1]: import pymongo

In [2]: con = pymongo.Connection("mongodb://client:[e-mail]: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，表明我无权读取该集合.我可以通过 meteor mongo <projectname 从 mongo 控制台读取它，但不能从 python 读取.我如何在 python 中读取它?

From what I can tell, this is mongo suggesting I don't have access to read from that collection. I can read from it from a mongo console via meteor mongo <projectname, but not from python. How can I read from it in python?

推荐答案

您的数据库似乎正在使用身份验证，而您尚未指定用户名/密码.在 python 中，这是通过 db.authenticate(username, password) 完成的.详情请见:http://api.mongodb.org/python/2.1.1/api/pymongo/database.html

It looks like your database is using authentication and you haven't specified a username/password. In python this is done with db.authenticate(username, password). Details here: http://api.mongodb.org/python/2.1.1/api/pymongo/database.html
