Meteor 流星+；铁制路由器&x2B；JSZip不工作

我正在尝试使用Meteor创建和提供一个zip文件。以下是我所拥有的：

Router.map ->
  @route "data",
    where: 'server'
    path: "/data"
    action: ->
      this.response.writeHead 200,
        'Content-Type': 'application/zip'
        'Content-Disposition': "attachment; filename=data.zip"
      zip = new JSZip()
      zip.file "Hello.txt", "Hello World"
      this.response.end zip.generate({ 'type': 'string', 'compression': 'DEFLATE'})

我有jszip.min.js和jszip-deflate.js。创建了一个zip文件，我可以下载它，但我无法使用存档管理器打开该文件（已损坏）。如果我用文本编辑器打开data.zip，我会看到“PK”加上两个十六进制字符

如何创建zip文件并将其返回

使用默认的base64编码进行压缩，并在end/write方法中指定响应编码：

Router.map ->
  @route "data",
    where: 'server'
    path: "/data"
    action: ->
      this.response.writeHead 200,
        'Content-Type': 'application/zip'
        'Content-Disposition': "attachment; filename=data.zip"

      zip = new JSZip()
      zip.file "Hello.txt", "Hello World"
      file = zip.generate({ 'compression': 'DEFLATE' })

      this.response.end file, 'base64'

Router.map ->
  @route "data",
    where: 'server'
    path: "/data"
    action: ->
      this.response.writeHead 200,
        'Content-Type': 'application/zip'
        'Content-Disposition': "attachment; filename=data.zip"

      zip = new JSZip()
      zip.file "Hello.txt", "Hello World"
      file = zip.generate({ 'compression': 'DEFLATE' })

      this.response.end file, 'base64'
