C# Asp.net MVC Web API调用重定向到Accountcontroller登录

我的代码是

RouteConfig:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Dashboard", action = "Index", id = UrlParameter.Optional }
        );
    }

    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

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

        config.Formatters.Clear();
        config.Formatters.Add(new JsonMediaTypeFormatter());
    }

public class ServicesController : ApiController
{
    public string Get()
    {
        return "Hello World";
    }

}

    public ActionResult Login(string returnUrl)
    {
        // User Login functionality
        ViewBag.ReturnUrl = returnUrl;

        return View();
    }

WebAPIConfig:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Dashboard", action = "Index", id = UrlParameter.Optional }
        );
    }

    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

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

        config.Formatters.Clear();
        config.Formatters.Add(new JsonMediaTypeFormatter());
    }

public class ServicesController : ApiController
{
    public string Get()
    {
        return "Hello World";
    }

}

    public ActionResult Login(string returnUrl)
    {
        // User Login functionality
        ViewBag.ReturnUrl = returnUrl;

        return View();
    }

WebAPI控制器：

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Dashboard", action = "Index", id = UrlParameter.Optional }
        );
    }

    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

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

        config.Formatters.Clear();
        config.Formatters.Add(new JsonMediaTypeFormatter());
    }

public class ServicesController : ApiController
{
    public string Get()
    {
        return "Hello World";
    }

}

    public ActionResult Login(string returnUrl)
    {
        // User Login functionality
        ViewBag.ReturnUrl = returnUrl;

        return View();
    }

帐户管理员：

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Dashboard", action = "Index", id = UrlParameter.Optional }
        );
    }

    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

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

        config.Formatters.Clear();
        config.Formatters.Add(new JsonMediaTypeFormatter());
    }

public class ServicesController : ApiController
{
    public string Get()
    {
        return "Hello World";
    }

}

    public ActionResult Login(string returnUrl)
    {
        // User Login functionality
        ViewBag.ReturnUrl = returnUrl;

        return View();
    }

Global.asax.cs

   protected void Application_Start()
    {                     
        GlobalConfiguration.Configure(WebApiConfig.Register);            
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }

我在这里面临的问题是： 1.当我在浏览器中调用Webapi时，它会重定向到

有什么想法吗

谢谢，

我想你的问题是你没有对webapiconfig采取行动：

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

您需要通过以下操作调用控制器：

并将[AllowAnonymous]添加为@qamar sais

FilterConfig.RegisterGlobalFilters（GlobalFilters.Filters）；-我怀疑其中包含身份验证过滤器。试着把它放在评论中。你是如何调用你的服务的？只需将URL“”放入浏览器？是的。通过简单地将url和它调用servicescontroller中的get函数，但返回登录页而不是json结果“hello world”，您在创建项目时是否选择了身份验证模式？尝试向控制器类添加[AllowAnonymous]属性，如果这样可以避免身份验证重定向，则在这种情况下，[authorize]web api控制器类上的属性将不起作用，而一旦这个问题得到解决，我需要实现web api的基本身份验证
