使用带有office js helpers身份验证程序的msgraph sdk javascript时出现令牌错误

我有一个使用React+TypeScript的Outlook加载项，使用Node.js进行本地调试。我正在使用office js helpers库进行身份验证，并使用msgraph sdk javascript图形客户端库。作为一名POC，我只是想通过id检索当前电子邮件的详细信息来验证我是否可以成功调用Graph。我可以成功使用office js helpers Authenticator对应用程序进行授权，并成功检索令牌

但是，当我使用图形客户端调用

v1/me/messages/{ID}

时，我得到：

“401 InvalidAuthenticationToken:访问令牌验证失败”

我不确定这是我使用验证器的方式有问题，还是我的外接程序或应用程序清单有问题。我的外接程序正在将这些用于

AppDomains

：

<AppDomains>
  <AppDomain>https://localhost:3000</AppDomain>
  <AppDomain>https://login.microsoftonline.com</AppDomain>
</AppDomains>

嗨，Eric，您是否能够验证用于调用graph的代码是否在没有外接程序部分的情况下自行正确构建？换句话说，你能把一些条目id硬编码到你试图检索邮件的部分，把它连接到一个简单的页面上，看看是否有效吗？另外，请记住，您必须使用Office.JS中的convertToRestId函数将从JSAPI获得的条目ID转换为Rest ID。我能够实现这一点。我不记得细节了，因为我在这个项目的地图上到处都是，不断地遇到新的问题，所以很难保持它们的直线。
