For AAD-B2C it is fairly simple. From Azure Portal with a B2C directory associated, go to your B2C directory (I added the "Azure AD B2C" to my portal's left menu). In the B2C directory click on "User flows (policies) directory menu item. In the policies pane click on one of your policies you previously added to select it. It should open a pane for the policy. Click "Properties". In the next pane is a section, "Token compatibility settings" which has a property "Issuer". Your AAD-B2C tenant GUID is contained in the URL.

您可以运行一个简单的curl调用来获得azure订阅的租户id，而无需任何身份验证。

做一个卷曲调用:

https://management.azure.com/subscriptions/{订阅id} ? api版本= 2015-01-01

请求失败，但您将能够从响应报头中获得租户id。租户id出现在一行中，后面跟着“WWW-Authenticate: holder authorization_uri="https://login.windows.net/"

您可以使用curl -v来显示响应头。

访问https://login.windows.net/YOURDIRECTORYNAME.onmicrosoft.com/.well-known/openid-configuration，您将看到一堆包含租户ID的url。

如果您已经在您的机器中安装了Azure CLI 2.0，那么您应该能够使用以下命令获得您所属的订阅列表:

az login

如果你想看到一个表输出，你可以使用

az account get-access-token --query tenant --output tsv

或者你可以使用Rest API

租户-列表|微软文档

如果你已经安装了Azure CLI，你可以运行下面的命令，

az account list

或者在~/.azure/credentials中找到它

当您浏览给定的Active Directory实例时，租户id也会出现在管理控制台URL中，例如:

https://manage.windowsazure.com/<morestuffhere>/ActiveDirectoryExtension/Directory/BD848865-BE84-4134-91C6-B415927B3AB1
