Question

一件有趣的事发生在我身上。真有趣，我仍然无法控制。

短篇小说：受https://www.stevejgordon.co.uk/extending-the-asp-net-core-identity-signinmanager的启发，我创建了一个自定义SignInManager并覆盖了PasswordSignInAsync方法。这项要求的背景是拥有第二个登录页面（带有PIN）。但是，当我尝试从新页面（LoginPin.cshtml）登录时，没有找到PasswordSignInAsync。

这是有趣的事情：当我从Login.cshtml页面执行相同操作时，它会被击中！

长话短说

public class AuditableSignInManager<TUser> : SignInManager<TUser> where TUser : class
{
    private readonly UserManager<TUser> _userManager;
    private readonly ApplicationDbContext _db;
    private readonly IHttpContextAccessor _contextAccessor;

    public AuditableSignInManager(UserManager<TUser> userManager, IHttpContextAccessor contextAccessor, IUserClaimsPrincipalFactory<TUser> claimsFactory, 
        IOptions<IdentityOptions> optionsAccessor, ILogger<SignInManager<TUser>> logger, ApplicationDbContext dbContext, IAuthenticationSchemeProvider schemes)
        : base(userManager, contextAccessor, claimsFactory, optionsAccessor, logger, schemes)
    {
        _userManager = userManager ?? throw new ArgumentNullException(nameof(userManager));
        _contextAccessor = contextAccessor ?? throw new ArgumentNullException(nameof(contextAccessor));
        _db = dbContext ?? throw new ArgumentNullException(nameof(dbContext));
    }

    public override async Task<SignInResult> PasswordSignInAsync(TUser user, string password, bool isPersistent, bool lockoutOnFailure)
    {
        //skipped for readability reasons 
var result = await base.PasswordSignInAsync(user, password, isPersistent, lockoutOnFailure);
    }
}

Startup.cs和依赖注入：

services.AddScoped<SignInManager<ApplicationUser>, AuditableSignInManager<ApplicationUser>>();

Login.cshtml.cs

public class LoginModel : PageModel
{
    private readonly SignInManager<ApplicationUser> _signInManager;
    private readonly ILogger<LoginModel> _logger;

    public LoginModel(SignInManager<ApplicationUser> signInManager, ILogger<LoginModel> logger)
    {
        _signInManager = signInManager;
        _logger = logger;
    }

    // skipped

    public async Task<IActionResult> OnPostAsync(string returnUrl = null)
    {
        var result = await _signInManager.PasswordSignInAsync(Input.UserName, Input.Password, false, lockoutOnFailure: false);
    }
}

LoginPin.cshtml.cs

public class LoginModelPin : PageModel
{


private readonly SignInManager<ApplicationUser> _signInManager;
    private readonly ILogger<LoginModelPin> _logger;

public LoginModelPin(SignInManager<ApplicationUser> signInManager, ILogger<LoginModelPin> logger)
{
    _signInManager = signInManager;
    _logger = logger;
}

public async Task<IActionResult> OnPostAsync(string returnUrl = null)
{
    var result = await _signInManager.PasswordSignInAsync(usrPwd, usrPwd, false, lockoutOnFailure: false);
}
}

说实话：这已经不再有趣了。有人可以指出我正确的方向吗？

非常感谢。

N。

尝试使用AddSignInManager<TSignInManager>>

https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.identity.identitybuilderextensions.addsigninmanager?view=aspnetcore-2.2

在自定义SignInManager（ASP.NET Core 2）中覆盖PasswordSignInAsync
