我正在尝试使用Protect an API by using OAuth 2.0 with Azure Active Directory and API Management文档在API管理实例中实现Azure Active Directory。该文档建议,为了获取访问令牌,我需要使用Developer Portal。

我的问题是:外部应用程序将与API Management通信。有没有办法省略Developer Portal并以编程方式获取访问令牌?

这很痛苦,但是多亏了Jos Lieben,我可以使用此Powershell功能来做到这一点

它专门用于代表组织授予API访问权限,但是如您所见,您可以提取命令以获取和使用API​​令牌。
