使用 Google 脚本编辑器将 Google 文档转换为 PDF

Question

我一直在尝试将 Google 文档文件转换为 PDF 文件，而无需使用下载选项。下面是我在脚本编辑器中使用的脚本，但它似乎不起作用。我认为错误是在 IF 语句之后。

function convertPDF() {
  doc = DocumentApp.getActiveDocument();
  docblob = DocumentApp.getActiveDocument().getAs('application/pdf');
  var result = DocumentApp.getUi().alert(
      'Save As PDF?',
      'Save current document (Name:'+doc.getName()+') as PDF',
      DocumentApp.getUi().ButtonSet.YES_NO);
  if (result == DocumentApp.getUi().Button.YES) {
    docblob.setName(doc.getName())
    folder.createFile(docblob);
    DocumentApp.getUi().alert('Your PDF has been converted to a PDF file.');
  } else {
    DocumentApp.getUi().alert('Request has been cancelled.');
  }
}

Answer 1

失败是因为文件夹未定义。如果您将其替换为 DriveApp，则将在根文件夹中创建 PDF，并且您的功能将起作用。您还可以在消息框中显示完整的 URL。

function convertPDF() {
  doc = DocumentApp.getActiveDocument();
  var ui = DocumentApp.getUi();
  var result = ui.alert(
      'Save As PDF?',
      'Save current document (Name:'+doc.getName()+'.pdf) as PDF',
      ui.ButtonSet.YES_NO);
  if (result == ui.Button.YES) {
    docblob = DocumentApp.getActiveDocument().getAs('application/pdf');
    /* Add the PDF extension */
    docblob.setName(doc.getName() + ".pdf");
    var file = DriveApp.createFile(docblob);
    ui.alert('Your PDF file is available at ' + file.getUrl());
  } else {
    ui.alert('Request has been cancelled.');
  }
}

Answer 2

将 PDF 保存在原始目录中：

function convertPDF() {
  doc = DocumentApp.getActiveDocument();
  // ADDED
  var docId = doc.getId();
  var docFolder = DriveApp.getFileById(docId).getParents().next().getId();
  // ADDED
  var ui = DocumentApp.getUi();
  var result = ui.alert(
      'Save As PDF?',
      'Save current document (Name:'+doc.getName()+'.pdf) as PDF',
      ui.ButtonSet.YES_NO);
  if (result == ui.Button.YES) {
    docblob = DocumentApp.getActiveDocument().getAs('application/pdf');
    /* Add the PDF extension */
    docblob.setName(doc.getName() + ".pdf");
    var file = DriveApp.createFile(docblob);
    // ADDED
    var fileId = file.getId();
    moveFileId(fileId, docFolder);
    // ADDED
    ui.alert('Your PDF file is available at ' + file.getUrl());
  } else {
    ui.alert('Request has been cancelled.');
  }
}

并添加这个通用功能

function moveFileId(fileId, toFolderId) {
   var file = DriveApp.getFileById(fileId);
   var source_folder = DriveApp.getFileById(fileId).getParents().next();
   var folder = DriveApp.getFolderById(toFolderId)
   folder.addFile(file);
   source_folder.removeFile(file);
}
