从Google云端硬盘获取FILE_ID？

I need, the most simple way to get some sort of object with a list of the FILE_ID's! I do not need a way to automatically grab the unique folder identifier, as I will do that manually. Please, keep it as simple as possible. Here's what I have so far:

    var fileID = ["uniquefileid","uniquefileid"];
    var folderID = "uniquefileid";
   document.getElementById("test2").innerHTML = "<iframe style='position:static; margin-top: -12px; margin-left: -1340px' src='https://drive.google.com/file/d/"+folderID+"_"+fileID[0]+"/preview' width='3480' height='1550' frameborder='0' scrolling='no'></iframe>";

Essentially, uniquefileid is replaced with a number (I don't want to share for obvious reasons), and the folderID will never change.

It seems I also can't $.get() from google either using ajax.Thank's for anyone who can guide me in the right direction.

Use files.list, and filter the response to return only fileIds. Here's the main important part from JS quickstart:

function listFiles() {
        gapi.client.drive.files.list({
          'pageSize': 10,
          'fields': "*"
        }).then(function(response) {
          appendPre('Files:');
          var files = response.result.files;
          console.log(response.result.files);

          if (files && files.length > 0) {
            for (var i = 0; i < files.length; i++) {
              var file = files[i];
              appendPre(file.id);
            }
          }
        });
      }

And sure enough it returns a list of IDs.

Output:

List of File Ids:
