requests 库可以完美地从 google 文档(来自 How do you save a Google Sheets file as CSV from Python 3 (or 2)?)检索 csv 或 txt 文件

但是当我尝试对 google doc 中的 pdf 文件执行相同操作时，我只能设法获取 HTML 文件，有什么方法可以让我从 google doc 下载 pdf 文件吗？例如https://docs.google.com/file/d/0BxcsLDhZbUBBMWY1MzRkZGQtMjQxNC00NzQ3LWFmNzEtNzNmMzYzYmU2MDRj/edit

我试过使用 requester，我得到了这个:

>>> import requests # https://pypi.python.org/pypi/requests
>>> gdoc = 'https://docs.google.com/file/d/0BxcsLDhZbUBBMWY1MzRkZGQtMjQxNC00NzQ3LWFmNzEtNzNmMzYzYmU2MDRj/edit'
>>> print requests.get(gdoc).text

输出:

我试过使用 urllib 并且我得到了:

>>> import urllib, codecs
>>> urllib.urlretrieve('https://docs.google.com/file/d/0BxcsLDhZbUBBMWY1MzRkZGQtMjQxNC00NzQ3LWFmNzEtNzNmMzYzYmU2MDRj/edit')
('/tmp/tmpQ5tDwR', <httplib.HTTPMessage instance at 0x16fbbd8>)
>>> codecs.open('/tmp/tmpQ5tDwR','r').read()

我得到了这个输出:http://pastebin.com/D2FM1VMU

最佳答案

这里的正确答案是使用 Google Drive API访问您的文档，而不是像普通的面向用户的网络浏览器那样尝试编写与 Google 文档对话的脚本。

按照您的操作方式，Google 认为您想要查看该页面。而且，由于您看起来不像是可以 native 查看 PDF 的浏览器，因此它对您很好，并创建了一个 HTML 查看器页面来让您阅读 PDF。该查看器页面确实具有“下载”功能，您可以尝试解析 HTML 和 JavaScript 并触发下载，但这需要大量工作。

此外，我敢打赌 Google 云端硬盘的服务条款明确禁止编写脚本和抓取网络界面。

API 确实需要您创建一个 API key ，您可能还需要 OAuth 来处理以正确用户身份登录。但是一旦你这样做了，它就会像你想做的那样容易使用——而且它确实有效。你做了一个Files: get请求从其 ID(您现有尝试中的一长串垃圾)获取有关该文件的信息，其中包括 downloadUrl字段，您只需获取该 URL。像这样的东西，在纯 stdlib 中:

url = 'https://www.googleapis.com/drive/v2/files/' + fileid
r = urllib2.urlopen(url)
filesinfo = json.load(r)
downloadurl = filesinfo['downloadUrl']
r2 = urllib2.urlopen(downloadurl)
data = r2.read()

requests 会让您在开始添加 API key 和可能的 OAuth 时变得更轻松——例如，您可以只传递 {'key': API_KEY} 而不是调用 urllib.urlencode在字典上将其添加为查询字符串。

Google API Client Library for Python将使事情变得更加简单——您可以在文档页面上看到示例代码。
