API instructions

Google Developers - OAuth 2.0 Playground:

• Click "Send the request".

Request URI instructions

All files in folder

Get specific fields of files in a folder:

https://www.googleapis.com/drive/v3/files?q="folderId"+in+parents&fields=files(md5Checksum,+originalFilename)
//

Replace "folderId" with the folder ID.

You can use &fields=files(*) to get all of the file's fields.

Single file

Get specific fields of a file:

https://www.googleapis.com/drive/v3/files/fileId?fields=md5Checksum,+originalFilename
//

Replace "fileId" with the file ID.

You can use &fields=* to get all of the file's fields.

Parsing the JSON response

• Open a JavaScript console.
• Save the object into a variable.
• Map the object.
• Copy the result.

Code

var response = {
  "files": [
    {
      "md5Checksum": "0cc175b9c0f1b6a831c399e269772661", 
      "originalFilename": "a.txt"
    }, 
    {
      "md5Checksum": "92eb5ffee6ae2fec3ad71c777531578f", 
      "originalFilename": "b.txt"
    }
  ]
};


var result = response.files.map(function (file) { return (file.md5Checksum + " *" + file.originalFilename); }).join("\r\n");

console.log(result);
copy(result);
