oauth2client/appengine.py使用webapp2/python27/wsgi返回"InvalidResponseError:标头值必须是str,得到'unicode'"

Question

事先,我的问题类似于App Engine上的金字塔问题"InvalidResponseError:标题值必须是str,得到'unicode',以及几个google-api-python-client错误,但在我的情况下没有任何帮助.而且,我没有回答问题#254(它本身看起来类似于#111,所以我在这里尝试.

在本地GAE上,下面的简单示例(此示例的简化&python27-ified版本)返回InvalidResponseError: header values must be str, got 'unicode',但我的代码没有执行任何unicode标头设置.更准确地说,我期待结果Hello,而我有:

Internal Server Error
    The server has either erred or is incapable of performing the requested operation.
    Traceback (most recent call last):
      File "/home/ronj/.gae/lib/webapp2-2.5.2/webapp2.py", line 1546, in __call__
        return response(environ, start_response)
      File "/home/ronj/.gae/lib/webob_0_9/webob/__init__.py", line 2000, in __call__
        start_response(self.status, self.headerlist)
      File "/home/ronj/.gae/google/appengine/runtime/wsgi.py", line 156, in _StartResponse
        (_GetTypeName(value), value, name))
    InvalidResponseError: header values must be str, got 'unicode' (u'https://accounts.google.com/o/oauth2/auth?state=http%3A%2F%2Flocalhost%3A8080%2F&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Foauth2callback&response_type=code&client_id=xxxxxxxxxxxx.apps.googleusercontent.com&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube&access_type=offline') for 'Location'

任何的想法？我在Ubuntu 12.10 x64上使用Python 2.7.3上的GAE 1.7.5.

编辑:Jonas在问题#254中提供了一个答案:"在生成URL的OAuth2WebServerFlow上的方法中添加一些str()应该相对容易.在oauth2client/client.py"第830行返回之前用str()换行".
→看起来很棒,但我该如何实现呢？我同意我可以修改我安装GAE的本地计算机上的文件,但是一旦部署,将会使用Google的GAE,对吧？我怎样才能覆盖它？(抱歉新手问题)

谢谢你的帮助!

我正在使用 GAE 的捆绑版本的 python API，这显然不应该这样做。google-api-python-client-1.1在项目下载页面上安装托管后，一切都按预期进行。
