python - 是否可以将 OAUTH 2 与 Google Reporting API 一起使用？

Question

我目前正在使用带有 GData 和 Python 的 Reporting API 的 OAuth 1 进行身份验证。是否可以使用 OAuth 2，我找不到可行的参考？

Answer 1

我无法找到 OAuth 2 和 Reporting api 的任何参考，但是通过 GData 库的示例（http://code.google.com/p/gdata-python-client/source/browse/#hg %2Fsamples%2Fapps) 我能够把它拼凑起来：

#!/usr/bin/python
