如何将链接转换为文件名？

Question

I have a Google spreadsheet file with almost 2000 rows of URL such as this one:

https://docs.google.com/uc?id=0B4ptELk-D3USblk1aWd1OWowRWs

Each URL contains an image, stored in Google Drive. My question is: How can I transform this link ( https://docs.google.com/uc?id=0B4ptELk-D3USblk1aWd1OWowRWs ) to a file name? For instance, I would like to know if it could be a /something/folder/Photofile1.jpg .

Is there anyway of doing this?

Answer 1

Try script:

function TESTgetFileName() {
  Logger.log(getFileName('0B4ptELk-D3USVi1NZ3ZGbkhqYXc'));
  //                      ^^^^^^^^^^ file ID ^^^^^^^^^
}


function getFileName(id) {
  var file = DriveApp.getFileById(id);
  var fileName = file.getName();    
  var strFolders = getFolders(file); 
  return strFolders + '/' + fileName;  
}

function getFolders(object) {

  var folders = object.getParents();
  if (!folders.hasNext()) { return 'My Drive'; } 
  var folder = folders.next();

  var folderNames = [];

  while (folder.getParents().hasNext()) {        
    var folderName = folder.getName();
    folderNames.unshift(folderName);
    folder = folder.getParents().next();
  }

  return folderNames.join('/');

}

Script function will return the result:

0B4ptELk-D3USVi1NZ3ZGbkhqYXc → My Drive/something/folder/Photofile1.jpg

Tests

I opened script editor, selected function TESTgetFileName and get the result

My Drive/Detalhes_Farmacia.Fotografia_Fachada_1.JPEG .

This function can be run from script, not directly from spreadsheets. When you try using it as custom formula from sheet, it throws error:

You do not have permission to call getFileById (line 8).

So better use it from script to get data and then write the result to the sheet.
