SignInManager.SignInAsync(...) 不会在 Core Blazor ASP.NET 登录

Question

我正在学习 ASP.Net 核心 Blazor 和SignInManager.SignInAsync以及SignInManager.PasswordSignInAsync不登录。我试过几次，但一直都失败了。我可以看到数据在 SQLServer 数据库表中。我看不到密码，但用户帐户在那里。我花了几天时间，但无法弄清楚

这是我的代码

登录页面组件

@page "/loginPage"
@using Microsoft.AspNetCore.Identity;
@using Microsoft.AspNetCore.Authentication;
@using GroupMembersInfo.Data;
@inject UserManager<IdentityUser> UserManager
@inject SignInManager<IdentityUser> SignInManager
@inject NavigationManager NavigationManager
<h3>Log In</h3>
<div class="row">
<div class="col-md-12">
<EditForm Model="@LoginUserModel" OnValidSubmit="@LogIn">
<DataAnnotationsValidator />
<ValidationSummary />
<div class="form-group">
<label>User Id: </label>
<input @bind-value="LoginUserModel.Email" class="form-control" />
</div>
<div class="form-group">
<label>Password: </label>
<input @bind-value="LoginUserModel.Password" class="form-control" />
</div>
<div class="form-group">
<button type="submit">Login</button>
</div>
</EditForm>
</div>
</div>
@code {
public LoginUserModel LoginUserModel { get; set; } = new LoginUserModel();
public async Task LogIn()
{
var user = new IdentityUser
{
UserName = LoginUserModel.Email,
Email = LoginUserModel.Email
};
user.PasswordHash = SignInManager.UserManager.PasswordHasher.HashPassword(user, LoginUserModel.Password);
AuthenticationProperties properties = new AuthenticationProperties();
properties.IsPersistent = true;
await SignInManager.SignInAsync(user, properties).ContinueWith(p =>
{
var User = System.Security.Claims.ClaimsPrincipal.Current;
NavigationManager.NavigateTo("/");
});
//var result = await SignInManager.PasswordSignInAsync(user, LoginUserModel.Password, isPersistent: false, lockoutOnFailure: false);
//if (result.Succeeded)
//{
//    var User = System.Security.Claims.ClaimsPrincipal.Current;
//    NavigationManager.NavigateTo("/");
//}
}
}

为什么不简单地使用给定的电子邮件和密码登录用户？

public async Task LogIn()
{
var result = await SignInManager.PasswordSignInAsync(LoginUserModel.Email, LoginUserModel.Password, isPersistent: false, lockoutOnFailure: false);
if (result.Succeeded)
{
NavigationManager.NavigateTo("/");
}
}
