学生成绩册.由于“拒绝访问:DriveApp"而无法完成脚本

问题描述

我的脚本从工作表学生"中获取 35 个学生姓名.然后找到带有他们名字的正确文件夹(即'Smith Peter')，删除旧的pdf文档，其中旧成绩保留他们的名字(即'Smith Peter.pdf')并将新制作的pdf保存到文件夹('Smith Peter')带有新成绩的文档('Smith Peter.pdf').并从名单中带走另一个学生.

My script takes 35 student names from the Sheet 'Studenti'. Then finds the proper folder with their name (i.e. 'Smith Peter'), removes old pdf document with old grades holding their name (i.e 'Smith Peter.pdf') and saves to the folder ('Smith Peter') a newly made pdf document with new grades ('Smith Peter.pdf'). And goes to take another student from the list.

问题:在 1,2 或 3 次迭代后，脚本停止说:访问被拒绝:DriveApp.(第 22 行，文件代码":files.next().setTrashed(true);).一周前脚本运行没有问题，我尝试在这里更改名称、文件夹、目的地、源表和检查建议.但没有成功.我不知道第22行有什么问题.请帮忙！

The problem: after 1,2 or 3 iterations the script stops saying: Access denied: DriveApp. (line 22, file "Code": files.next().setTrashed(true);). A week ago the script was working without problems, I tried to change names, folders, destinations, source sheets and checked advice here. But no success. I don't know what is wrong with the line 22. Please help!

执行脚本(显示脚本停止的位置)

Execution transcript (shows where the script has stopped)

function generatePdf() {

var report = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet(); // Gradebook ready to save as pdf
var zasobnik = SpreadsheetApp.openById('1eygLDH0iJoXfcVOMIin0hnKpMF59HszmXZosPKvwYWc');  
var zasobsheet = zasobnik.getSheetByName("Studenti"); // list of 35 students with names, Folder IDs
var data = zasobsheet.getDataRange().getValues(); 
  
for (var i = 1; i < data.length; i++){
    report.getRange('B2').setValue(data[i][0]); // setting student's name in a gradebook (first column)
    report.getRange('B3').setValue(' '); // just to jump from B2 to B3
  
var pdf = DriveApp.getFileById('1WHwm7xK28Orj22RxaKWEsCl3UWvWxYUhRg4ZGf87-GQ'); // ID of Gradebook (IF of ActiveSpreadsheet)
var theBlob = pdf.getBlob().getAs('application/pdf').setName(data[i][0] + ".pdf");
var folder = DriveApp.getFolderById(data[i][2]); // third column
  
var files = DriveApp.getFilesByName(data[i][0] + ".pdf"); // pdf with old grades
      while (files.hasNext()) {    
       files.next().setTrashed(true);    
   }
var newFile = folder.createFile(theBlob); // creating pdf with new grades in the student's folder
 
 }
}

推荐答案

我也遇到了同样的问题，即我不拥有的垃圾文件.我发现了

I have the same problem with trashing files, that I don't own. I found that

1. 如果您在 getEditors() 或 getViewers() 列表中，我有解决方案:只需撤销您自己的权限即可.file.revokePermissions(Session.getActiveUser());文件将消失.
2. 如果文件设置了 isShareableByEditors()，则示例 1 不起作用 - 如果它为false"，则您无法执行任何操作.
3. 如果您已将文件添加到您的驱动器，该文件可供拥有链接的所有人公开访问，则您无法撤消权限，因为您没有权限.应用脚本返回访问被拒绝.所以，我认为我可以 setTrashed(true).我错了.Google 还返回拒绝访问:DriveAp.

在案例 2 和 3 到应用程序脚本的情况下，我没有找到从驱动器中删除不需要的文件的方法.但是仍然可以通过单击它们并选择删除"选项来实现.

I didn't find a way to remove unwanted files from my drive in case 2 and 3 thru apps script. But it's still possible by clicking on them and choosing option "Remove".
