问题
Im trying to connect to a MongoLabs mongodb server I setup for a small project Im working on. I can connect fine when connecting from my local machine, but when I try to make a connection from my Mediatemple server I get a 'Invalid ns' error:
Unable to connect to MongoDB: Failed to connect to: dsXXXXXX.mongolab.com:27769: send_package: the query returned a failure: Invalid ns [XXXXXX_dev/XXXXXX_dev.$cmd] (code: 16256)
Any suggestions on how to fix this would be a major help.
回答1:
Perhaps your database name in your connection string or collection name (together they make a namespace) have special characters, and they make the namespace name illegal.
So you should make sure your connection string is ok.
For example, mine looks like
mongodb://mydblogin:mydbpassword@ds044444.mongolab.com:44444/mydatabase
Also make sure that collection name is legal.
