使用googleapps脚本下载Google幻灯片演示文稿作为PowerPoint文档?

googleslides的GUI提供下载GSlides演示文稿作为Powerpoint(myFile.pptx)。我在googleapps脚本文档中找不到等价的东西-任何指针?

感谢评论和回答,我尝试了以下片段:

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);
  }
}

从application/vnd.google-apps.presentation转换为应用程序/vnd.openxmlformats-officedocument.presentationml.presentation

第二次编辑

根据评论中的另一个建议,我尝试从googleappscript发出一个http调用,直接将gslides转换为pptx,而不受大小限制。它在G驱动器上生成一个文件,但该文件已损坏/无法读取。气体脚本:

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);
}

笔记:

使用mime类型 'pptx' 返回相同的错误消息

这次修改怎么样?

response.getContent() 返回字节数组。所以请使用 response.getBlob()

修改脚本:

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));
}

如果您想在您的谷歌驱动器中转换未发布的谷歌幻灯片,请使用访问令牌。届时请修改 url 如下所示。
- var url = 'https://docs.google.com/presentation/d/' + fileId + '/export/pptx?access_token=' + ScriptApp.getOAuthToken();
DriveApp.createFile() 在根文件夹上创建一个文件作为默认值。

正如tehhowch所提到的,您可以从驱动器中获取Google幻灯片文件并将其作为 .pptx . (不确定mime类型。)

function convertFileToPptx() {
  var fileId = "Your File ID";
  var outputFileName = "name.pptx";

  var url = 'https://docs.google.com/presentation/d/' + fileId + '/export/pptx';
  //var rootFolder = DriveApp.getRootFolder();
  var rootFolder = DriveApp.getFolderById("Your Folder ID")
  var params = {method:"GET", headers:{"authorization":"Bearer "+ ScriptApp.getOAuthToken()}};
  var response = UrlFetchApp.fetch(url,params);
  var blobPptx = response.getBlob();
  var result = rootFolder.createFile(blobPptx.setName(outputFileName));
}
