防止重命名 Google 表单文件上传

Question

我有一个 Google 表单，它使用以下网站上提到的文件上传功能， https://sites.google.com/site/scriptsexamples/home/announcements/google-forms-file-upload-feature

我想知道两件事：

有没有办法防止重命名上传的文件。（即：original_file_name - 上传者姓名）
关于以下引述：

If a respondent decides to upload a file directly from his Drive, a copy will be made and the form owner will become owner of the copy.

是否可以识别原始文件并将其删除，以免它破坏上传者根驱动器文件夹。

function getCurrentResponses() {
  var form = FormApp.openById('formID');
  var formResponses = form.getResponses();
  var numResponses = formResponses.length;  
  var lastResponse = formResponses[numResponses - 1];
  var lastResponseItem = lastResponse.getItemResponses();
  var emailAddress = lastResponseItem[0].getResponse();
  Logger.log('emailAddress: ' + emailAddress);
  var zone = lastResponseItem[1].getResponse();
  Logger.log('zone: ' + zone);
  var projectName = lastResponseItem[2].getResponse();
  Logger.log('projectName: ' + projectName);
  var igeURL = lastResponseItem[3].getResponse();
  Logger.log('igeURL: ' + igeURL);

//Creating folder for submitted project
  var DriveFolder = DriveApp.getFolderById("destinationFolder");
  var folderName = projectName;
  //create the folder
  var folderpath = DriveFolder.createFolder(folderName).addEditor(emailAddress).getId(); 
//get the path to the folder
  var pathtoemail = "https://drive.google.com/drive/folders/"+folderpath;
  var file = DriveApp.getFileById(igeURL);
  file.getParents().next().removeFile(file);
  DriveApp.getFolderById(folderpath).addFile(file);
  var fileName = file.getName();

  //Create the message and subject of the email 
var message = 'Thank you for submitting. Here is the link to your drive folder. Please use this folder to upload and receive related documentation. ' +pathtoemail ;  //a custom message, feel free to change anything inside the quotes 

var subject = "Form Related Documentation." ;  
//send the email
     MailApp.sendEmail(emailAddress, subject, message, {
  // cc: 'email@email.com'         // optional cc

 });

Answer 1

我只是想 post 我能够创建一个重命名文件的解决方法。

var form = FormApp.openById('formID');
var formResponses = form.getResponses();
var numResponses = formResponses.length;  
var lastResponse = formResponses[numResponses - 1];
var lastResponseItem = lastResponse.getItemResponses();      
var submittedID = lastResponseItem[3].getResponse();
var file = DriveApp.getFileById(submittedID);
var oldFileName = file.getName();
var indexOldFileName = oldFileName.indexOf("-");
var newFileName = oldFileName.slice(0,indexOldFileName - 1);
var indexOldFileExt = oldFileName.lastIndexOf(".");
var newFileExt = oldFileName.slice(indexOldFileExt);
var modName = newFileName + newFileExt;
file.setName(modName);

关于我的第二个问题，我还是没能解决。如果我找到解决方案，我会post。

Answer 2

我稍微更改了您的代码，将文件名更改为其 ID。

function changenametoid() {
var form = FormApp.openById('formID');
var formResponses = form.getResponses();
var numResponses = formResponses.length;  
var lastResponse = formResponses[numResponses - 1];
var lastResponseItem = lastResponse.getItemResponses();      
var submittedID = lastResponseItem[0].getResponse();
var file = DriveApp.getFileById(submittedID);
var oldFileName = file.getName();
var indexOldFileName = oldFileName.indexOf("-");
var newFileName = submittedID;
var indexOldFileExt = oldFileName.lastIndexOf(".");
var newFileExt = oldFileName.slice(indexOldFileExt);
var modName = newFileName + newFileExt;
file.setName(modName);
}
