c# - 此请求的授权已被拒绝。总是

Question

我已经创建了一个 MVC webApi 项目，现在我想使用身份验证和授权。我想我已经实现了这种安全措施，但由于某种原因，有些事情变糟了，当我编写我的凭据并尝试调用一些 webApi 方法时，显示消息“此请求的授权已被拒绝”。

这是我实现的代码。

WebApi配置:

public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();

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

        config.Filters.Add(new AuthorizeAttribute());
    }

路由配置:

public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Routing", action = "LogIn", id = UrlParameter.Optional }
        );
    }

Controller :

public class RoutingController : Controller
{
    //
    // GET: /Routing/
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Projects()
    {
        return View();
    }

    public ActionResult Users()
    {
        return View();
    }

    public ActionResult LogIn()
    {
        return View();
    }

    [HttpPost]
    public JsonResult LogInPost(string userName, string password)
    {
        User user = new User();
        RoleByUser rByU = new RoleByUser();
        password = UserController.EncriptPassword(password);
        string url = string.Empty;
        var checkUser = user.Get(userName);
        var userExists = (from userInList in checkUser where userInList.UserName == userName && userInList.Password == password select userInList).FirstOrDefault();
        if(userExists!= null)
        {
            var roles = (from roleByUser in userExists.listOfRole select roleByUser.RoleName.Trim()).ToArray();
            IPrincipal principal = new GenericPrincipal(
            new GenericIdentity(userExists.UserName), roles);
            SetPrincipal(principal);
            url = "Routing/Users";
        }
        return Json(url);
    }

    private void SetPrincipal(IPrincipal principal)
    {
        Thread.CurrentPrincipal = principal;
        if (System.Web.HttpContext.Current != null)
        {
            System.Web.HttpContext.Current.User = principal;
        }
    }

}

            <div id="remember" class="checkbox">

            Forgot the password?
        </a>
    </div><!-- /card-container -->
</div><!-- /container -->

JS:

$(document).ready(function () { $('#btnLogIn').click(logIn); });

function logIn() {
    $.ajax({
        type: "POST",
        url: "http://localhost:21294/Routing/LogInPost",
        dataType: "json",
        data: { userName: $('#txtUserName').val(), password: $('#txtPassword').val() },
        success: function (data) {
            if(data!= "" && data!= undefined && data!= null)
                window.location.href = data;
        },
        error: function (err, e, error) {
            toastr.error('Error')
        }
    });

您应该将 [AllowAnonymous] 属性添加到 Controller 的 LogInPost

当您将 AuthorizeAttribute 添加到您的过滤器时，它会导致您的 Controller 假定默认情况下他们需要对所有操作进行授权，包括用于登录的操作。
