Question

我能够连接到我的远程数据库（当然是在身份验证之后）到数据库。但我无法执行任何命令甚至列表集合。

mongo_url = "blah.com:12345"
db_name = "db_name"
db_user_name = "user"
db_password = "password"
mongo_uri = "mongodb://" + db_user_name + ":" + db_password + "@" + mongo_url + "/" + db_name
connection = pymongo.MongoClient(mongo_uri)
db = connection[db_name]
print db.authenticate(db_user_name, db_password)  // Returns True

但是我无法使用如下命令： db.collection_names()或使用db.command()

的任何命令

我得到了这个错误堆栈（sayng Authentcation失败）：

OperationFailure: Authentication failed.

但是我可以从我的mongo shell中执行这些操作。

无法使用pymongo在远程mongo中执行命令
