C＃Unity中的AWS Cognito用户身份验证

我一直在努力让AWS Cognito用户授权在Unity 2017中运行。

根据此请求，Unity SDK存在限制： https://forums.aws.amazon.com/thread.jspa?threadID=248872

我尝试了几种不同的方法，而我最接近的是这里的代码： https://gist.github.com/dbeattie71/44ea3a13145f185d303e620c299ab1c5

然而，当我调用LoginUser并设置了所有细节时，我得到了这个堆栈：

我认为您可能会发现AWSSDK.Extensions.CognitoAuthentication很有用，它会增强AWS SDK for .NET，这在AWS Cognito和身份验证领域非常有限。特别是该库处理SRP协议，这是开发人员在我在GitHub上看到的一些项目中编写自己的东西。

在亚马逊博客文章here

中对此库进行了很好的介绍
