Recommended OAuth authentication Methods

I now need to write an open source program that has some of the functionality to get all the files in a folder of Dropbox users.
Because it is an open source program, at first I think it's best to use Basic Auth or XAuth, but Dropbox doesn't seem to support it (I didn't find the relevant information)
When I was ready to use OAuth 2.0, it suddenly occurred to me that OAuth 2.0 was needed Callback Url . Because open source program everyone will put their own website, this Callback Url certainly can't be different, so I again troubled. Do I have to use an intermediary agent?

So I would like to ask, there is no good for my needs of the authentication method or the network disk services.
