My desktop application, written in java, tries to download public files from Google Drive. As i found out, it can be implemented by using file's webContentLink (it's for ability to download public files without user authorization).
Download File Google Drive Api
Download File: https://suseqmoenu.blogspot.com/?file=2vKv6O
All you have to do is simple get the host URL for a publicly shared drive folder. To do this, you can upload a plain HTML file and preview it in Google Drive to find your host URL.
You essentially need to first download the normal download link, which however redirects you to the "Download anyway" page. You need to store cookies from this first request, find out the link pointed to by the "Download anyway" button, and then use this link to download the file, but reusing the cookies you got from the first request.
It will redirect you to an index type page with a giant subdomain, but you should be able to see the files in your folder. Then you can right click to save the link to the file you want (I noticed that this direct link also has this big subdomain for googledrive.com). Worked great for me with wget.
If you just want to programmatically (as oppossed to giving the user a link to open in a browser) download a file through the Google Drive API, I would suggest using the downloadUrl of the file instead of the webContentLink, as documented here: -downloads
To download a blob file stored on Drive, use the files.get method with the ID of the file to downloadand the alt=media URL parameter. The alt=media URL parameter tells theserver that a download of content is being requested as an alternative responseformat.
