Asp.net mvc MVC 5 OWIN-外部登录时IsAuthenticated为false（QQ连接）

我希望有人能帮我解决这个问题——我快疯了

我正在尝试使用tinysnake的QQ连接提供商通过QQ连接（OAuth 2.0）进行外部登录：

一切似乎都进行得很顺利-我可以通过我的QQ帐户登录，并通过适当的声明等回复到我的ExternalLoginCallBack方法。 我使用这些值通过IAAuthenticationManager登录用户-一切顺利。然而，当我将用户重定向到另一个页面并检查他是否登录时，我从IsAuthenticated值中得到一个假值。。。我也看不到我之前提出的任何主张

这可能是一个简单的解决方案，但我现在看不到：）

一些代码：

AuthConfig:

public static void ConfigureAuthentication(IAppBuilder app)
{
    app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

    // Normal cookie sign in
    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login"),
        AuthenticationMode = AuthenticationMode.Active
    });

    // QQ CONNECT
    app.UseQQConnectAuthentication(
        appId: "XXXXXX",
        appSecret: "XXXXXXXXXXXXXXXXX");
}

//
// POST: /Account/ExternalLogin
[System.Web.Mvc.HttpPost]
[System.Web.Mvc.AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult ExternalLogin(string provider, string returnUrl)
{
    // Request a redirect to the external login provider
    return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl }));
}

//
// GET: /Account/ExternalLoginCallback
[System.Web.Mvc.AllowAnonymous]
[HostAuthentication(DefaultAuthenticationTypes.ExternalCookie)]
public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
    var ctx = Request.GetOwinContext();
    var result = ctx.Authentication.AuthenticateAsync(DefaultAuthenticationTypes.ExternalCookie).Result;
    var claims = result.Identity.Claims.ToList();
    var name = claims.First(i => i.Type == "urn:qqconnect:name");

    claims.Add(new Claim(ClaimTypes.AuthenticationMethod, "QQ"));
    claims.Add(new Claim(ClaimTypes.Name, name.Value));

    var ci = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ExternalCookie);
    ctx.Authentication.SignIn(ci);

    // DO OTHER STUFF HERE

    return Redirect("~/");
}

public ActionResult Index()
{
    var model = new HomeViewModel();

    var ctx = Request.GetOwinContext();
    if (ctx.Authentication.User.Identity.IsAuthenticated)  // <-- THIS RETURNS FALSE
    {
        var claimsIdentity = User.Identity as ClaimsIdentity;
        model.Name = claimsIdentity.FindFirst(ClaimTypes.Name).Value;
        model.IsAuthenticated = true;
    }

    return View(model);
}

会计控制器：

public static void ConfigureAuthentication(IAppBuilder app)
{
    app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

    // Normal cookie sign in
    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login"),
        AuthenticationMode = AuthenticationMode.Active
    });

    // QQ CONNECT
    app.UseQQConnectAuthentication(
        appId: "XXXXXX",
        appSecret: "XXXXXXXXXXXXXXXXX");
}

//

public ActionResult ExternalLogin(string provider, string returnUrl)
{
    // Request a redirect to the external login provider
    return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl }));
}

//
// GET: /Account/ExternalLoginCallback
[System.Web.Mvc.AllowAnonymous]
[HostAuthentication(DefaultAuthenticationTypes.ExternalCookie)]
public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
    var ctx = Request.GetOwinContext();
    var result = ctx.Authentication.AuthenticateAsync(DefaultAuthenticationTypes.ExternalCookie).Result;
    var claims = result.Identity.Claims.ToList();
    var name = claims.First(i => i.Type == "urn:qqconnect:name");

    claims.Add(new Claim(ClaimTypes.AuthenticationMethod, "QQ"));
    claims.Add(new Claim(ClaimTypes.Name, name.Value));

    var ci = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ExternalCookie);
    ctx.Authentication.SignIn(ci);

    // DO OTHER STUFF HERE

    return Redirect("~/");
}

public ActionResult Index()
{
    var model = new HomeViewModel();

    var ctx = Request.GetOwinContext();
    if (ctx.Authentication.User.Identity.IsAuthenticated)  // <-- THIS RETURNS FALSE
    {
        var claimsIdentity = User.Identity as ClaimsIdentity;
        model.Name = claimsIdentity.FindFirst(ClaimTypes.Name).Value;
        model.IsAuthenticated = true;
    }

    return View(model);
}

//

到目前为止一切似乎都进展顺利

家庭控制器：

public static void ConfigureAuthentication(IAppBuilder app)
{
    app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

    // Normal cookie sign in
    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
        LoginPath = new PathString("/Account/Login"),
        AuthenticationMode = AuthenticationMode.Active
    });

    // QQ CONNECT
    app.UseQQConnectAuthentication(
        appId: "XXXXXX",
        appSecret: "XXXXXXXXXXXXXXXXX");
}

//
// POST: /Account/ExternalLogin
[System.Web.Mvc.HttpPost]
[System.Web.Mvc.AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult ExternalLogin(string provider, string returnUrl)
{
    // Request a redirect to the external login provider
    return new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl }));
}

//
// GET: /Account/ExternalLoginCallback
[System.Web.Mvc.AllowAnonymous]
[HostAuthentication(DefaultAuthenticationTypes.ExternalCookie)]
public async Task<ActionResult> ExternalLoginCallback(string returnUrl)
{
    var ctx = Request.GetOwinContext();
    var result = ctx.Authentication.AuthenticateAsync(DefaultAuthenticationTypes.ExternalCookie).Result;
    var claims = result.Identity.Claims.ToList();
    var name = claims.First(i => i.Type == "urn:qqconnect:name");

    claims.Add(new Claim(ClaimTypes.AuthenticationMethod, "QQ"));
    claims.Add(new Claim(ClaimTypes.Name, name.Value));

    var ci = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ExternalCookie);
    ctx.Authentication.SignIn(ci);

    // DO OTHER STUFF HERE

    return Redirect("~/");
}

public ActionResult Index()
{
    var model = new HomeViewModel();

    var ctx = Request.GetOwinContext();
    if (ctx.Authentication.User.Identity.IsAuthenticated)  // <-- THIS RETURNS FALSE
    {
        var claimsIdentity = User.Identity as ClaimsIdentity;
        model.Name = claimsIdentity.FindFirst(ClaimTypes.Name).Value;
        model.IsAuthenticated = true;
    }

    return View(model);
}

public ActionResult Index（）
{
var模型=新的HomeViewModel（）；
var ctx=Request.GetOwinContext（）；
如果（ctx.Authentication.User.Identity.IsAuthenticated）/根据我的理解，您所经历的是意料之中的。过于简单化了：

应用程序获取外部信息并使用它创建外部cookie
外部cookie发送到您的应用程序时，假设它只是一个临时cookie，将用于查找有关用户的任何其他本地信息，然后转换为本地[应用程序]cookie

如果有人可以澄清的话，也有类似的问题。
