这是我几个星期以来一直遇到的问题。具体来说，这似乎发生在我在帐户控制器中的登录操作上。似乎也取决于我用来浏览站点的机器，因为我只在家用机器而不是工作机器上遇到问题。我知道它不是特定于浏览器的，因为两者都使用相同版本的Chrome。它也不是孤立在单个环境中的，因为我可以在本地进行调试并浏览网站本身。
起初，我认为这与我使用异步方法有关，因为我对同步方法的使用并不熟悉。我尝试剥离所有内容并使其完全同步，同时仍获得相同的结果。然后，我尝试将redirecttoaction / route / locals替换为仅返回视图，并且它起作用了。为了进一步确认这是罪魁祸首，我让登录表单遇到了一个完全不同的动作，除了简单的redirecttoaction（“ Index”，“ Home”）以外，它都是空的OTHER，并且该应用程序无限期地挂起。不幸的是，仅点击一个视图并不能满足我的需要，因为在很多情况下，我需要它来击打动作本身。
就其不一致而言，我能够一致地复制它的唯一方法是在本地运行该应用程序并登录。然后关闭浏览器并停止运行该应用程序。然后我再次运行该应用程序>注销>登录，它挂起。
我在stackoverflow和其他站点上进行了大量研究，并尝试了许多不同的建议，例如更改startup.cs中的配置设置，重新安装dll以及其他许多不计其数的事情，没有运气解决这个问题。
这里是构造函数，并且从帐户控制器登录get和post操作
private myContext _context;
private readonly UserManager<ApplicationUser> _userManager;
private readonly SignInManager<ApplicationUser> _signInManager;
private readonly RoleManager<IdentityRole> _roleManager;
private readonly IEmailSender _emailSender;
private readonly ISmsSender _smsSender;
private readonly ILogger _logger;
public AccountController(
myContext context,
UserManager<ApplicationUser> userManager,
SignInManager<ApplicationUser> signInManager,
RoleManager<IdentityRole> roleManager,
IEmailSender emailSender,
ISmsSender smsSender,
ILoggerFactory loggerFactory)
{
_context = context;
_userManager = userManager;
_signInManager = signInManager;
_roleManager = roleManager;
_emailSender = emailSender;
_smsSender = smsSender;
_logger = loggerFactory.CreateLogger<AccountController>();
}
// GET: /Account/Login
[HttpGet]
[AllowAnonymous]
public IActionResult Login(string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
return View();
}
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null)
{
ViewData["ReturnUrl"] = returnUrl;
if (ModelState.IsValid)
{
ApplicationUser user = _userManager.Users.Where(a => a.Email == model.Email).FirstOrDefault();
if (user != null)
{
var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: true);
if (result.Succeeded)
{
_logger.LogInformation(1, "User logged in.");
var RoleCustomer = _userManager.IsInRoleAsync(user, "Customer");
var RoleAdmin = _userManager.IsInRoleAsync(user, "Admin");
if (RoleCustomer.Result)
{
return RedirectToLocal(returnUrl);
}
else if (RoleAdmin.Result)
{
return RedirectToRoute(new { controller = "Home", action = "Admin" });
//return RedirectToLocal("/Home/Index");
}
else
{
ModelState.AddModelError(string.Empty, "Invalid login attempt.");
return View(model);
}
}
if (user.EmailConfirmed == false)
{
return View("ResendConfirm", new ResendConfirmViewModel() { user = user, returnUrl = returnUrl });
}
if (result.IsLockedOut)
{
_logger.LogWarning(2, "User account locked out.");
return View("Lockout");
}
else
{
ModelState.AddModelError(string.Empty, "Invalid login attempt.");
return View(model);
}
}
else
{
ModelState.AddModelError(string.Empty, "Invalid login attempt.");
return View(model);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
这是登录视图中的登录表单
<form asp-controller="Account" asp-action="Login" asp-route-returnurl="@ViewData["ReturnUrl"]" method="post" class="form-horizontal" role="form">
<h4>Use a local account to log in.</h4>
<hr />
<div asp-validation-summary="All" class="text-danger"></div>
<div class="form-group">
<label asp-for="Email" class="col-md-2 control-label"></label>
<div class="col-md-10">
<input asp-for="Email" class="form-control" />
<span asp-validation-for="Email" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<label asp-for="Password" class="col-md-2 control-label"></label>
<div class="col-md-10">

<span asp-validation-for="Password" class="text-danger"></span>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<div class="checkbox">

@Html.DisplayNameFor(m => m.RememberMe)
</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<button type="submit" class="btn btn-default">Log in</button>
</div>
</div>
<p>
<a asp-action="Register" asp-route-returnurl="@ViewData["ReturnUrl"]">Register as a new user?</a>
</p>
<p>
<a asp-action="ForgotPassword">Forgot your password?</a>
</p>
</form>
