身份3 SignInManager.PasswordSignInAsync()不返回任何结果 [英] Identity 3 SignInManager.PasswordSignInAsync() doesn't return any result

问题描述

我正在使用Identity 3.0创建Web应用程序，并且SignInManager PasswordSignInAsync()方法有问题.我就像在文档中一样使用它，但是它不返回任何内容(应用程序代码仅在此处停止)这是我的控制器代码:

I am creating web application with Identity 3.0 and have problems with SignInManager PasswordSignInAsync() method. I'm using it just like in documentation, but it doesn't return anything ( application code just stop there ) Here`s my controller code:

 public class AppController : Controller
{
    private IAccountService _service;
    private readonly SignInManager<User> _signInManager;
    private UserManager<User> _userManager;

    public AppController(IAccountService service, SignInManager<User> signInManager, UserManager<User> userManager)
    {
        _service = service;
        _signInManager = signInManager;
        _userManager = userManager;
    }

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Login(LoginViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = await _userManager.FindByEmailAsync(model.Email);
            var password = await _userManager.CheckPasswordAsync(user, model.Password);

            var result = await _signInManager.PasswordSignInAsync(
                model.Email,
                model.Password,
                model.RememberMe,
                lockoutOnFailure: false);

            if (result.Succeeded)
            {
                return RedirectToAction(nameof(EmployeeController.Contact), "Employee");
            }
            if (result.IsLockedOut)
            {
                return View("Lockout");
            }
            if(result.IsNotAllowed)
            {
                return View("Not Allowed");
            }
            else
            {
                ModelState.AddModelError(string.Empty, "Invalid login attempt.");
                return View(model);
            }
        }
        return View(model);
    }
}

startup.cs文件中的配置:

And configuration in startup.cs file:

public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
        services.AddCaching();
        services.AddSession(options => {
            options.IdleTimeout = TimeSpan.FromMinutes(30);
            options.CookieName = ".MyApplication";
        });

        services.AddEntityFramework()
        .AddSqlServer()
        .AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(Configuration["Data:DbContextConnection"]));


        services.AddIdentity<User, UserRole>(config => 
            {
                config.User.RequireUniqueEmail = true;
                config.Password.RequiredLength = 8;
                config.Cookies.ApplicationCookie.LoginPath = "/App/Login";
                config.SignIn.RequireConfirmedEmail = false;
                config.SignIn.RequireConfirmedPhoneNumber = false;
            })
        .AddEntityFrameworkStores<ApplicationDbContext,string>()
        .AddDefaultTokenProviders();

        services.AddTransient<IAccountService, AccountService>();
    }

public void Configure(IApplicationBuilder app)
    {
        app.UseStaticFiles();

        app.UseSession();

        app.UseIdentity();
        app.UseMvc(config =>
        {
            config.MapRoute(
                name: "Default",
                template: "{controller}/{action}/{id?}",
                defaults: new { controller = "App", action = "Index" }
                );
        });
    }

推荐答案

'PasswordSignInAsync()'方法不能采用'model.Email'作为第一个参数，它可以使用用户名来检查用户.以下是方法:

The 'PasswordSignInAsync()' method cant take 'model.Email' as the first argument, it can check up for the user using his username.Here is the method:

 public virtual Task<SignInStatus> PasswordSignInAsync(
    string userName,
    string password,
    bool isPersistent,
    bool shouldLockout) 

如果要检查电子邮件，可以使用 SignInAsync()方法，但这是在检查 CheckPasswordAsync()之后是真的这是您可能会做的:

if you want to go through checking the email you can use the SignInAsync() method but that is after checking if the CheckPasswordAsync() is true here is what you could possibly make:

var user = await _userManager.FindByEmailAsync(model.Email);
var password = await _userManager.CheckPasswordAsync(user, model.Password);

if(password)
{
   var result = await _signInManager.SignInAsync(
                    model.Email,
                    model.Password,
                    model.RememberMe);
     if (result.Succeeded)
     {
          return RedirectToAction(nameof(EmployeeController.Contact), "Employee");
     }
}

但是由于 SignInAsync()不支持该参数，现在您将无法检查lockoutOnFailure，要检查它，您必须制作另一个显式方法

But now you wont be able to check the lockoutOnFailure since the SignInAsync() dont support this argument,to check it you have to make another explicit method
