Multiple parameters with the same name don't work about bdboauth1manager

This is not something that I will be "fixing," because it's a non-issue as far as I'm concerned. If you feel so inclined to take it upon yourself and implement this ability, be my guest, and I will entertain any pull requests you submit. However, considering the fact that this is built on top of the AFNetworking library, you may want to take a while to understand the internals of how it builds requests and serializes parameters. You'll quickly find that it uses dictionaries throughout when dealing with request parameters. If this is something you absolutely require support for, I suggest exploring alternatives to AFNetworking.
