在 Web API 项目 .net core 6 MVC 中更改默认页面

Question

我有 ASP.net 核心 **WebAPI ** 项目，之后我在这个项目中创建了 Scaffolded item witch Identity。如何将默认页面更改为 Identity/page/login.cshtml 而不是 ~/swagger/index.html 谢谢

将默认页面从 ~/swagger/index.html 更改为 Identity/page/login.cshtml 谢谢

我的代码在这里 应用用户.cs

public class AppUser: IdentityUser <int>
    {
        public string FullName { get; set; }
        public DateTime DateCreated { get; set; }
        public DateTime DateModified { get; set; }

    }

程序.cs

builder.Services.ConfigureApplicationCookie(options =>
{
    options.LoginPath = $"/Identity/Account/Login";
    options.LogoutPath = $"/Identity/Account/Logout";
    options.AccessDeniedPath = $"/Identity/Account/AccessDenied";
});

AppDbContext.cs

public class AppDbContext : IdentityDbContext<AppUser, IdentityRole<int>, int>
    {
        public AppDbContext(DbContextOptions<AppDbContext> options) 
         : base(options)
        {
        }
         ...........................................
     }

_LoginPartial.cshtml

@using Claim.Data.Entities
@using Microsoft.AspNetCore.Identity

@inject SignInManager<AppUser> SignInManager
@inject UserManager<AppUser> UserManager

当我测试点击登录进入登录页面

错误： InvalidOperationException：尝试激活“XXXXXXX.Areas.Identity.Pages.Account.LoginModel”时，无法解析“Microsoft.AspNetCore.Identity.SignInManager`1[Microsoft.AspNetCore.Identity.IdentityUser]”类型的服务。

您好已经解决了问题。我必须更改 Login.cshtmal.sc 文件。 但是我遇到了身份验证问题，无法登录

 SignInManager.IsSignedIn(User) <- return claims = 0

_loginPatial.cshtml

    @using Microsoft.AspNetCore.Identity
    
    @inject SignInManager<IdentityUser> SignInManager
    @inject UserManager<IdentityUser> UserManager
    
    <ul class="navbar-nav">
    @if (SignInManager.IsSignedIn(User)) 
    {
        <li class="nav-item">
            <a id="manage" class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Hello @UserManager.GetUserName(User)!</a>
        </li>
        <li class="nav-item">
            <form id="logoutForm" class="form-inline" asp-area="Identity" asp-page="/Account/Logout" asp-route-returnUrl="@Url.Action("Index", "Home", new { area = "" })">
                <button id="logout" type="submit" class="nav-link btn btn-link text-dark">Logout</button>
            </form>
        </li>
    }
    else
    {
        <li class="nav-item">
            <a class="nav-link text-dark" id="register" asp-area="Identity" asp-page="/Account/Register">Register</a>
        </li>
        <li class="nav-item">
            <a class="nav-link text-dark" id="login" asp-area="Identity" asp-page="/Account/Login">Login</a>
        </li>
    }
    </ul>

Login.cshtml.cs

if (result.Succeeded) <------ true

    public async Task<IActionResult> OnPostAsync(string? returnUrl = null)
            {
                returnUrl ??= Url.Content("~/");
    
                ExternalLogins = (await _signInManager.GetExternalAuthenticationSchemesAsync()).ToList();
    
                if (ModelState.IsValid)
                {
                    // This doesn't count login failures towards account lockout
                    // To enable password failures to trigger account lockout, set lockoutOnFailure: true
                    var result = await _signInManager.PasswordSignInAsync(Input.Email, Input.Password, Input.RememberMe, lockoutOnFailure: false);
                    if (result.Succeeded)
                    {
                        _logger.LogInformation("User logged in.");
                        return LocalRedirect(returnUrl);
