PyMongo 身份验证失败答案

【问题描述】：

我用 mongolab 建立了一个数据库，其中 db 与集合具有相同的名称。我决定我不喜欢这个删除它并制定了一个更好的命名方案。我为新数据库添加了一个新用户/密码并尝试进行身份验证。它一直在失败。不知道为什么。我仔细检查了我的凭据，它们是正确的。我检查了 mongolab 提供的 URI，这也是正确的。此代码适用于第一个数据库。

这是我的登录代码

def __init__(self, user_id, password, database, collection):
        # mongodb://<dbuser>:<dbpassword>@ds017205.mlab.com:17205/words
        mongodb_uri = "mongodb://" + user_id + ":" + password + "@ds017205.mlab.com:17205/" + database
        client = pymongo.MongoClient(mongodb_uri)
        db = client[database]
        self.collection = db[collection] # is declared in class

这会产生以下错误

Error

我们将不胜感激。谢谢

【问题讨论】：

您使用的是什么版本的 pymongo 和 MongoDB？根据authentication examples doc page，您需要对密码中的任何字符进行转义吗？
我使用的是最新版本的 mongodb 和 pymongo。下载了最近的一个三四天去。为 pymongo 安装了 pip
刚刚尝试转义密码中的特殊内容并得到相同的结果。它也可以在没有转义的情况下工作。

【解决方案1】：

代码没有问题...设置的 db 用户在设置框中输入了两次相同的错误密码，因此它被接受了，然后当代码尝试使用实际正确答案时，它显然不起作用原因。感谢大家观看
