调用SignInAsync后，User.Identity.IsAuthenticated返回false [英] User.Identity.IsAuthenticated returns false after SignInAsync invoked

问题描述

我有一个弹出表单，我使用jquery UI对话框加载我的登录视图.单击登录"按钮时，我使用ajax post调用帐户/登录"操作.这是我的代码:

I have a pop up form in that form I load my Login view using jquery UI dialog .When the Login button is clicked I invoke the Account/Login action using ajax post .Here is my code :

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = await UserManager.FindAsync(model.UserName, model.Password);
        if (user != null)
        {
           await SignInAsync(user, model.RememberMe);
           //IsAuthenticated is returns false 
           bool isAuthenticated= User.Identity.IsAuthenticated;
            return PartialView("_LoginPartial");
        }
        else
        {
            ModelState.AddModelError("", "Invalid username or password.");
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

在调用SignInAsync方法之后，User.Identity.IsAuthenticated返回false为何会发生这种情况?

after the SignInAsync method is invoked ,the User.Identity.IsAuthenticated is returns false why thats happening?

推荐答案

这是因为asp.net管道尚未对用户进行身份验证.

This because the asp.net pipeline has not authenticated the user.

User.Identity.IsAuthenticated 值基于HttpContext.Current.应该发生的是 SignInAsync 将添加一个cookie，框架将使用该cookie来认证将来的请求.

The User.Identity.IsAuthenticated value is based on HttpContext.Current. What should happen is SignInAsyncwill add a cookie that the framework will use to authenticate future requests.

因此，在击中该Controller动作之后. User.Identity.IsAuthenticated 在所有控制器操作中均为true. AuthorizeAttribute 基于此.

So after this Controller action has been hit. User.Identity.IsAuthenticated will be true in all controller actions. The AuthorizeAttribute is based on this.

要获取用户名，我将查看 UserManager.FindAsync 返回的用户属性

To get the username i would look at the user property that UserManager.FindAsync has returned i.e.

var userName = user.UserName
