其实它比这更简单。文件已经是Blob（任何具有getBlob（）的文件都可以传递给任何需要Blob的函数）。所以代码如下所示：

Actually it's even easier than that. Files are already Blobs (anything that has getBlob() can be passed in to any function that expects Blobs). So the code looks like this:

var folder = DocsList.getFolder('path/to/folder');
folder.createFile(Utilities.zip(folder.getFiles(), 'newFiles.zip'));

另外，如果您在文件夹中有多个具有相同名称的文件，它将不起作用。 。谷歌云端硬盘文件夹支持，但Zip文件不支持。

Additionally, it won't work if you have multiple files with the same name in the Folder... Google Drive folders support that, but Zip files do not.

为了使这个工作可以使用多个同名的文件：

To make this work with multiple files that have the same name:

var folder = DocsList.getFolder('path/to/folder');
var names = {};
folder.createFile(Utilities.zip(folder.getFiles().map(function(f){
  var n = f.getName();
  while (names[n]) { n = '_' + n }
  names[n] = true;
  return f.getBlob().setName(n);
}), 'newFiles.zip'));
