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。

获取tenantID的简单方法是:

Connect-MsolService -cred $LiveCred  #sign in to tenant

(Get-MSOLCompanyInformation).objectid.guid  #get tenantID

截至目前(06/07/2018)，一个简单的方法是在Azure门户中运行Azure云Shell中的az帐户显示(需要存储帐户)。

——命令——

az account show

——命令输出——

{
  "environmentName": "AzureCloud",
  "id": "{Subscription Id (GUID)}",
  "isDefault": true,
  "name": "{Subscription Name}",
  "state": "Enabled",
  "tenantId": "{Tenant Id (GUID)}",
  "user": {
    "cloudShellID": true,
    "name": "{User email}",
    "type": "user"
  }
}

有关Azure Cloud Shell的更多详细信息，请参阅Azure Cloud Shell | Microsoft Docs概述。

只是为一个老问题(但仍然相关的问题)添加一个新方法。 在新的门户中，在任何屏幕上单击帮助图标并选择“显示诊断”将显示一个JSON文档，其中包含所有租户信息，包括TenantId、租户名称以及更多有用的信息

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.
