WebApi身份验证未应用于MVC

Question

我有一个带有自定义身份验证服务器的ASP.NET MVC应用程序。当用户想要登录时，应用程序弹出窗口，完成后，返回令牌，然后应用程序通过WebApi、登录用户

var cl = from d in (this.User.Identity as ClaimsIdentity).Claims
         select new Claim(d.Type, d.Value);
var identity = new ClaimsIdentity(cl, "ApplicationCookie");
AuthenticationManager.SignIn(identity);
var name = cl.FirstOrDefault(x => x.Type.ToLower() == "login").Value;
Thread.CurrentPrincipal = new TaiAuthPrincipal(identity);
System.Web.Security.FormsAuthentication.SetAuthCookie(name, true);

在每一个请求上，WebApi都知道谁是用户，平均定义了User.Identity；但在MVC视图中，它总是空的，并且这些都不执行

<div class="headerPane">
    @{
        if (User.Identity.IsAuthenticated)
        {
            @Html.Partial("HeaderPartialView")
        }
        if (HttpContext.Current.User.Identity.IsAuthenticated)
        {
            @Html.Partial("HeaderPartialView")
        }
        if (System.Threading.Thread.CurrentPrincipal.Identity.IsAuthenticated)
        {
            @Html.Partial("HeaderPartialView")
        }
    }
</div>

如何从web api到mvc对用户进行身份验证？应用程序基于前端的angularjs，因此所有授权工作都在前端通过webapi请求完成。所以mvc什么都不知道。

为了充分起见，这是TaiAuthPrincipal，确实没有什么特别的

public class TaiAuthPrincipal : IPrincipal
    {
        private IIdentity identity;
        public IIdentity Identity
        {
            get { return identity; }
        }
        public bool IsInRole(string role)
        {
            var _role = (this.Identity as ClaimsIdentity).Claims.FirstOrDefault(x => x.Type.ToLower().Contains("GroupName".ToLower()));
            return _role == null ? false : true;
        }
        public TaiAuthPrincipal(IIdentity _identity)
        {
            this.identity = _identity;
        }
        public TaiAuthPrincipal(ClaimsIdentity _identity)
        {
            this.identity = _identity as IIdentity;
        }
    }

全球.asax

void MvcApplication_PostAuthenticateRequest(object sender, EventArgs e)
        {
            if (HttpContext.Current.Request.Url.AbsolutePath.StartsWith("/api/"))
            {
                System.Web.HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);
            }
        }

启动.cs

public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
            app.UseOAuthBearerAuthentication(new Microsoft.Owin.Security.OAuth.OAuthBearerAuthenticationOptions());
        }
    }

如果您在MVC应用程序的同一项目中制作WebApi，那么您验证Web请求的方式是完全错误的。发生的情况是，当您通过调用操作请求视图时，mvc项目需要一个经过身份验证的请求，所以您需要做的是将您的accesstoken保存在客户端的cookie中，并将其与每个请求一起发送到服务器，从该令牌中识别用户并设置IPrincipal。通过这个答案，它将帮助你

ASP.NET MVC-设置自定义IIdentity或IPrincipal

你的代码看起来像这个

protected void Application_PostAuthenticateRequest(Object sender, EventArgs e)
{
    HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
    if (authCookie != null)
    {
        FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
        JavaScriptSerializer serializer = new JavaScriptSerializer();
        CustomPrincipalSerializeModel serializeModel = serializer.Deserialize<CustomPrincipalSerializeModel>(authTicket.UserData);
        CustomPrincipal newUser = new CustomPrincipal(authTicket.Name);
        newUser.Id = serializeModel.Id;
        newUser.FirstName = serializeModel.FirstName;
        newUser.LastName = serializeModel.LastName;
        HttpContext.Current.User = newUser;
    }
}
