c# - 我的基本身份验证 Web api 未在任何浏览器中弹出身份验证

Question

我想显示用户名密码以验证用户。在哪里更改它以获取身份验证弹出。下面是 webapi.config 文件

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services
    var cors = new EnableCorsAttribute("*", "*", "*");
    config.EnableCors(cors);

    // Web API routes
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
}

api控制器

[BasicAuthentication]
[Route("Reactor")]
[HttpGet]
public HttpResponseMessage Get()
{
    string username = Thread.CurrentPrincipal.Identity.Name;
}
