我正在尝试让 Oauth 使用 Python 与 Google API 一起工作。我尝试了不同的 oauth 库，例如oauth、oauth2和djanog-oauth，但我无法让它工作（包括提供的示例）。
为了调试 Oauth，我使用 Google 的Oauth Playground，并且我研究了API和Oauth 文档
对于某些库，我正在努力获得正确的签名，而对于其他库，我正在努力将请求令牌转换为授权令牌。如果有人可以使用上述库之一向我展示 Google API 的工作示例，那将真正对我有什么帮助。
编辑：我最初的问题没有得到任何答案，所以我添加了我的代码。这段代码不起作用有两个可能的原因：
1）谷歌没有授权我的请求令牌，但不太确定如何检测到这个
2）访问令牌的签名无效，但我想知道哪些 oauth 参数谷歌期待，因为我能够在第一阶段生成正确的签名。
这是使用 oauth2.py 和 Django 编写的，因此是 HttpResponseRedirect。
