使用401发送消息:Asp.net Web-api

Muh*_*hid 6 asp.net-mvc http-status-code-401 asp.net-mvc-4 asp.net-web-api

我在asp.net web API中.在登录方法中,我检查数据库的用户/密码,如果它们不匹配,我会返回401状态代码和invalid user or password methodlike

var content = new StringContent("Invalid user name or password");
var message = new HttpResponseMessage(HttpStatusCode.Unauthorized);
message.Content = content;
throw new HttpResponseException(message);

但API似乎忽略了我的消息,只是简单地返回一些HTML

这是为什么?我怎么能覆盖这个呢?

导致此响应的一个潜在原因是 IIS 网站被配置为允许表单身份验证。查看这篇关于配置 IIS 以禁用 Web API 的表单身份验证的较旧但仍然有效的帖子。
