如何使用 C# 在 Bot framework v4 中知道哪个用户已通过身份验证？

Question

我有一个使用框架 v4 和 c# 制作的机器人。它已使用 azure ad 进行了身份验证。已在 azure 广告中添加用户列表。一旦用户登录，我们有什么办法知道哪个用户登录了。我们能知道机器人中用户的姓名或电子邮件ID吗？

我已按照此链接对带有广告的机器人进行身份验证。

您正在遵循正确的文档。如果您查看示例 24.bot-authentication-msgraph，则 Bot Framework v4 机器人身份验证使用 MS Graph 示例。此示例使用 Graph API 来检索有关用户的数据。设置 AADv2 应用程序并添加范围后，您可以在模拟器上本地测试机器人示例。登录后，如果您输入 'me'，它将返回用户名。

下面是示例如何在模拟器中工作的示例：

希望这会有所帮助。
