pymongo gridfs mongodb 身份验证失败

Question

我正在使用 gridfs 从我的 MongoDB 数据库

存储和获取文件

fs = gridfs.GridFS(MongoClient('mongodb://username:password@XX.XX.XX.XXX:27017/').mydb)

并获取我正在使用的文件

file = fs.get_last_version(file_name).read()

在这一行我得到身份验证失败异常。

当我的 mongo 数据库没有身份验证时一切正常。

数据库的其他使用工作正常。我有一个使用 flask_pymogno 连接到数据库的 python 服务和一个也使用 c# 连接到数据库的 c# 应用程序，并且所有连接都使用相同的凭据。

Answer 1

解决了。问题实际上是在我的密码中包含“+”字符。它是一个保留的 URI 字符。通过将“+”替换为“%2B”来修复此问题，现在可以使用了。
