C# 无法对客户端进行身份验证，错误：IDX20804:无法从以下位置检索文档：'；[PII隐藏]'；

我在使用Azure AD B2C（承载令牌）的.Net Core API时遇到了一个问题。该应用程序运行良好，但我还想编写单元测试，例如简单GET。我在运行测试时遇到以下错误：

System.Net.Http.HttpRequestException : Error while copying content to a stream.

听起来好像它正在尝试获取元数据JSON文档。如果要在不使用auth的情况下运行测试，可以将测试配置为在未配置auth的环境中运行。否则，您必须正确配置它，以便它能够获取元数据；（请记住在将代码发布到生产环境之前删除此选项）
