Google App Engine OAuth端点投入生产400

我使用Python 实现了对Google App Engine 的实验性OAuth支持,并让它在本地工作,但是当我部署到appspot时,端点投入了400.

例如,url http(s)://my-app.appspot.com/_ah/OAuthGetRequestToken返回400,但本地该url模式的行为与预期一致.

我尝试了http和https,并假设appspot处理ssl证书.

UPDATE

我一直在使用OAuth Playground来测试我的代码.尽管文档,似乎注册您的应用程序的需要.转到这里了解如何登记的说明.根据注册过程中的文档,在App Engine上运行时不需要证书.Playground正在显示有关错误的更多详细信息 - "签名无效".如果我理解正确,签名是从签名基本字符串生成的.在这种情况下,我使用基本字符串7DYB6MJ2s-IQcd7VJYJUmcct.

最终更新

有两件事导致400.首先,应用程序没有注册.Google的文档说这是可选的,但事实并非如此.其次,请求没有正确签署. 这是一个出色的调试工具来测试您的OAuth请求:Oauth Playground
