我创建了一个带有测试控制器的简单api，并将其作为Azure Api应用程序发布。我启用了公共（匿名）访问，swagger ui在浏览器中运行良好，并且swagger正确验证，我已经添加了Logic Apps所需的默认响应设置。
但是，当我尝试将Api应用程序添加到我的Logic App时，我遇到了一个错误：“获取swagger api定义时出错”。
如果我尝试在门户网站中浏览API定义，我会遇到另一个错误“无法获取API定义。可能需要在API应用程序上进行其他配置或身份验证。”
如果我尝试从门户网站链接下载swagger数据，则会失败并显示Http 400: Bad Request。
我在这里缺少什么，如何在门户网站上使用这个简单的Api应用程序？
