使用Google Apps脚本下载PowerPoint文档形式的Google幻灯片演示文稿? [英] Downloading a Google Slides presentation as PowerPoint doc using Google Apps Script?

问题描述

Google幻灯片的GUI提供了将GSlides演示文稿下载为Powerpoint(myFile.pptx)的功能.我在Google Apps脚本文档中找不到等效项-是否有任何指针?

The GUI of Google Slides offers to download a GSlides presentation as a Powerpoint (myFile.pptx). I could not find the equivalent in the Google Apps Script documentation - any pointer?

感谢评论和答案，我尝试了以下代码段:

Thanks to comments and answers, I tried this snippet:

function testFileOps() {
  // Converts the file named 'Synthese' (which happens to be a Google Slide doc) into a pptx
  var files = DriveApp.getFilesByName('Synthese');
  var rootFolder = DriveApp.getRootFolder();
  while (files.hasNext()) {
    var file = files.next();
    var blobPptx = file.getBlob().getAs('application/vnd.openxmlformats-officedocument.presentationml.presentation');
    var result = rootFolder.createFile(blobPptx);
  }
}

它返回一个错误:

从application/vnd.google-apps.presentation转换为 application/vnd.openxmlformats-officedocument.presentationml.presentation 不支持. (第7行，文件代码")

Converting from application/vnd.google-apps.presentation to application/vnd.openxmlformats-officedocument.presentationml.presentation is not supported. (line 7, file "Code")

根据评论中的另一个建议，我尝试通过Google App Script进行http调用，该调用将gslides直接转换为pptx，没有大小限制.它在G盘上生成一个文件，但该文件已损坏/不可读. GAS脚本:

As per another suggestion in comments, I tried to make an http call from Google App Script, that would directly convert the gslides into pptx, without size limit. It produces a file on G Drive, but this file is corrupted / unreadable. The GAS script:

function convertFileToPptx() {
  // Converts a public Google Slide file into a pptx
 var rootFolder = DriveApp.getRootFolder();
 var response = UrlFetchApp.fetch('https://docs.google.com/presentation/d/1Zc4-yFoUYONXSLleV_IaFRlNk6flRKUuAw8M36VZe-4/export/pptx');
 var blobPptx = response.getContent();
 var result = rootFolder.createFile('test2.pptx',blobPptx,MimeType.MICROSOFT_POWERPOINT);
}

注意:

• 我得到了pptx的mime类型在这里
• 使用mime类型'pptx'会返回相同的错误消息

• I got the mime type for pptx here
• using the mime type 'pptx' returns the same error message

推荐答案

此修改如何?

• response.getContent()返回字节数组.因此，请使用response.getBlob().

• response.getContent() returns byte array. So please use response.getBlob().

function convertFileToPptx() {
  var fileId = "1Zc4-yFoUYONXSLleV_IaFRlNk6flRKUuAw8M36VZe-4";
  var outputFileName = "test2.pptx";

  var url = 'https://docs.google.com/presentation/d/' + fileId + '/export/pptx';
  var rootFolder = DriveApp.getRootFolder();
  var response = UrlFetchApp.fetch(url);
  var blobPptx = response.getBlob();
  var result = rootFolder.createFile(blobPptx.setName(outputFileName));
}

注意:

• 如果要在Google云端硬盘中转换未发布的Google幻灯片，请使用访问令牌.那时，请按以下方式修改url.
  • var url = 'https://docs.google.com/presentation/d/' + fileId + '/export/pptx?access_token=' + ScriptApp.getOAuthToken();

  Note:

  • If you want to convert Google Slides, which are not published, in your Google Drive, please use access token. At that time please modify url as follows.
    • var url = 'https://docs.google.com/presentation/d/' + fileId + '/export/pptx?access_token=' + ScriptApp.getOAuthToken();
    • 类HTTPResponse
    • getOAuthToken()
    • Class HTTPResponse
    • getOAuthToken()
