Question

我正在使用Identity 3.0创建Web应用程序，并且遇到SignInManager PasswordSignInAsync（）方法的问题。我就像在文档中一样使用它，但它不会返回任何内容（应用程序代码只是停在那里）这是我的控制器代码：

 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);
    }
}

在startup.cs文件中配置：

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" }
                );
        });
    }

感谢您的帮助

Answer 1

'PasswordSignInAsync（）'方法无法将'model.Email'作为第一个参数，它可以使用他的用户名来检查用户。这是方法：

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

如果您想查看电子邮件，可以使用 SignInAsync（）方法，但检查后是 CheckPasswordAsync（）是真的这是你可能做的：

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"); } }

但是现在你无法检查lockoutOnFailure，因为 SignInAsync（）不支持这个参数，要检查它你必须制作另一个显式方法

如果您正在使用为 ASP.NET Core 创建最新标识的 Blazor 实现

    var user = await UserManager.FindByEmailAsync(_loginRequest.Email);

    if (user != null && await UserManager.CheckPasswordAsync(user, _loginRequest.Password))
    {
        _showInvalidLoginMessage = false;

        var token = await UserManager.GenerateUserTokenAsync(user, TokenOptions.DefaultProvider, "SignIn");

        var data = $"{user.Id}|{token}";

        var parsedQuery = System.Web.HttpUtility.ParseQueryString(new Uri(NavigationManager.Uri).Query);

        var returnUrl = parsedQuery["returnUrl"];

        if (!string.IsNullOrWhiteSpace(returnUrl))
        {
            data += $"|{returnUrl}";
        }

        var protector = DataProtectionProvider.CreateProtector("SignIn");

        var pdata = protector.Protect(data);

        NavigationManager.NavigateTo("/account/signinactual?t=" + pdata, forceLoad: true);
    }
    else
    {
        _showInvalidLoginMessage = true;
    }

（您需要在项目上安装 Microsoft.AspNetCore.DataProtection
