getIdForEmail() not a function in Google Drive API Permissions

Question

I need to change the permission of every uploaded file. But when I try to add this code,

printPermissionIdForEmail(email) {
var request = gapi.client.drive.permissions.getIdForEmail({
  'email': email,
});
request.execute(function(resp) {
  return ('ID: ' + resp.id);
});

}

I got an error of getIdForEmail is not a function.

gapi.client.init, gapi.auth2.getAuthInstance(), 

are working. But why gapi.client.drive.permissions.getIdForEmail is not working? There is something I need to do? in Google Developers Page? in my Code?

Answer 1

getIdForEmail is a method only available in Google Drive v2.

With V3 you are going to have to go after it in another manner.

Do a files.list with the q parameter. In the q parameter supply the user whos permissions you wish to change. You can see here how to use search This would find all the files where someuser is the owner.

'someuser@gmail.com' in owners

Then you will get a list of file resources you can then check the permissions on each file using permissions.list and use that to change the ones you need.

I am not a JavaScript developer but I found this in the documentation it shows how to use search to list files.

  /**
   * Print files.
   */
  function listFiles() {
    gapi.client.drive.files.list({
      'q': "'someuser@gmail.com' in owners",
      'fields': "*"
    }).then(function(response) {
      appendPre('Files:');
      var files = response.result.files;
      if (files && files.length > 0) {
        for (var i = 0; i < files.length; i++) {
          var file = files[i];
          appendPre(file.name + ' (' + file.id + ')');
        }
      } else {
        appendPre('No files found.');
      }
    });
  }

Update:

I just spotted this. About.get Gets information about the user, the user's Drive, and system capabilities

{
 "user": {
  "kind": "drive#user",
  "displayName": "Linda Lawton",
  "photoLink": "xxxx",
  "me": true,
  "permissionId": "060305882255734372",
  "emailAddress": "xxxx@gmail.com"
 }
}

Could that be the same permissionId you were looking for?
