asp.net-mvc - Asp.net Identity : User. Identity.GetUserId() 始终为 null，User.Identity.IsAuthenticated 始终为 false

Question

请参阅下面的代码:

var result = await SignInManager.PasswordSignInAsync(model.UserName, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
    case SignInStatus.Success:
        string UserId = User.Identity.GetUserId(); 
        return RedirectToAction("ClientDetails","Home");
    case SignInStatus.LockedOut:
        return View("Lockout");
    case SignInStatus.RequiresVerification:
        return RedirectToAction("SendCode", "Account", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
    case SignInStatus.Failure:
    default:
        ModelState.AddModelError("", "Invalid login attempt.");
        return View(model);
}

UserId 始终为 null，User.Identity.IsAuthenticated 始终为 false。但我可以查看需要身份验证的 View ClientDetails。

我假设您的示例是 AccountController.Login() 方法中的代码。我遇到了与您相同的问题，但发现用户对象在下一个请求之前不会被填充。尝试这种方法:

case SignInStatus.Success:
    return RedirectToAction("DoWork", "Account");


public async Task<ActionResult> DoWork()
{
    //this works
    string UserId = User.Identity.GetUserId();
    //return to View or Redirect again
}
