OWIN:webapi调用在Azure中返回401未授权错误

Question

我已经为前端创建了两个应用程序(使用AngularJs和Asp.Net MVC创建),而后端我使用了Web Api应用程序.

我正在尝试使用前端的表单身份验证来保护我的应用程序,并在后端实现基本表单身份验证.

当我在IIS本地测试时,它工作正常.但是当我在Azure中托管我的应用程序时,带有身份验证属性的API调用返回401未经授权的错误.

响应标题:

通过

使用表单身份验证的azure frontEND应用程序的请求中不会添加授权和Cookie参数.

我查看我的后端应用程序的身份验证/授权配置在azure它设置off.can任何身体知道什么是问题或我需要在azure portal中配置.提前谢谢.

这个问题是由于你可以通过添加你的请求来解决这个问题，

 $http({
  ....
  headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
  withCredentials: true,
  })
