Google Drive API file lists

What is the best way to get all files contained in a folder using Google Drive API (OAuth2)?

For example, with Dropbox, it's just a simple query to (1 request):

https://api.dropbox.com/1/metadata/dropbox/{folder}

For Skydrive, it is:

https://apis.live.net/v5.0/{folder}

and then querying the upload_location (2 requests).

According to the Google API Documentations, for Google Drive, it's possible to make request to

https://www.googleapis.com/drive/v2/files/{folder}/children

To get data so that data.items containing ID of children. However, with this method, if the folder has n files, then it requires to make n+1 requests (1 for getting lists of items, and n for each item).

I think that making n+1 requests for such basic task is too many. Is that the way Google Drive API designed, or is there a faster method of querying all files (with enough metadata) inside a folder?

You can use the list endpoint and limit results to files having a given parent.

See https://developers.google.com/drive/v2/reference/files/list:

https://www.googleapis.com/drive/v2/files?q='id'+in+parents

This returns much more metaData than the children endpoint

I'm no expert but it looks like the way you've described is the way the API is designed. Just from the https://developers.google.com/drive/v2/reference/children/list it looks like it you are intended to get a List of ChildrenReference's, then from each item in that you get its file ID, then use the files().get(fileID) function to get each file from there.
