(Unicode C) Google Drive Insert PermissionThis example demonstrates how to insert a permission for a file (see https://developers.google.com/drive/v2/reference/permissions/insert) The impetus for creating this example was a need to be able to view files uploaded using a service account key in the Google Drive web interface. When using a service account access token, the files your application will see are those for the service account, and not the files for your main account. For example, the Google Account I use for testing has a username of "support@chilkatcloud.com". (Don't send email to support@chilkatcloud.com, it's just use for testing and not interactively read.) I use "support@chilkatcloud.com" when I log into Google interactively to view files in Google Drive at https://drive.google.com/drive/my-drive. The files I upload to Google Drive using a service account key won't be visible in the browser UI. To make them visible, you need to insert a permission for the file so that the main user account, which in this case is "support@chilkatcloud.com", is a reader. After the permission is inserted, the file will be visible under "Shared with me" -- as if another Google Drive account shared the file with you.
