.Net 核心 API Microsoft.AspNet.Identity.Core

Question

我的问题。

所以我的问题是如何将使用 Microsoft.AspNetCore.Identity 的 .Net Core API 连接到使用 .Net 4.5 和 Microsoft.AspNet.Identity.Core 创建的身份（AspNetUser）表

细节。

我有一个 MVC Web 应用程序，它允许用户注册登录名，并根据那里的凭据查看某些信息。 这是用 .Net4.5 编写的。 我假设使用 Microsoft.AspNet.Identity.Core。 （我认为这是非 .NET 核心版本。这不是最好的命名约定）这个项目不能改变。

我正在尝试扩展一些功能，例如登录和注册以使用 API。 我正在尝试在 .Net Core 和 Microsoft.AspNetCore.Identity 中构建 API；

我创建了一个简单的测试登录控制器。

    [ApiController]
    public class AuthController : ControllerBase
    {

        private readonly UserManager<IdentityUser> _userManager;
        private readonly SignInManager<IdentityUser> _signInManager;
        private readonly IConfiguration _config;
        public AuthController(UserManager<IdentityUser> userManager,
                              SignInManager<IdentityUser> signInManager,
                                 IConfiguration config)
        {
            _userManager = userManager;
            _signInManager = signInManager;
            _config = config; ;
        }

 

      
        [HttpPost]
        [AllowAnonymous]
        public async Task<IActionResult> Login(LoginDto user)
        {
            if (ModelState.IsValid)
            {
                var testResult = await _signInManager.PasswordSignInAsync(user.Username, user.Password, false, false);
                return Ok(testResult);
            }
            return BadRequest();
        }
    }

最初我遇到了无效列错误，因为与 .NET4.5 系统创建的 AspNetUsers 表相比，现在创建的 AspNetUsers 表似乎带有附加字段。

我通过在 dbcontext 类的 ModelBuilder 中忽略它们来解决这个问题

    {

        public AuthConext(DbContextOptions<AuthConext> options) : base(options) { }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);


            modelBuilder.Entity<IdentityUser>().Ignore(c => c.PhoneNumberConfirmed)
                                             .Ignore(c => c.TwoFactorEnabled)
                                             .Ignore(c => c.SecurityStamp)
                                             .Ignore(c => c.LockoutEnabled)
                                             .Ignore(c => c.NormalizedEmail)
                                             .Ignore(c => c.NormalizedUserName)
                                             .Ignore(c => c.ConcurrencyStamp)
                                             .Ignore(c => c.LockoutEnd);
        }
    }

但是，我没有收到有关 LINQ 查询的错误。

    .Where(i => i.NormalizedUserName == __normalizedUserName_0)' could not be translated. Additional information: Translation of member 'NormalizedUserName' on entity type 'IdentityUser' failed. This commonly occurs when the specified member is unmapped. Either rewrite the query in a form that can be translated, or switch to client evaluation explicitly by inserting a call to 'AsEnumerable', 'AsAsyncEnumerable', 'ToList', or 'ToListAsync'.

虽然它确实提出了解决方案。 我不确定在哪里进行更改，因为我不是自己创建查询，只是简单地调用 _signInManager.PasswordSignInAsync。

所以我的问题是如何使用 Microsoft.AspNetCore.Identity 连接 .Net Core API 和使用 .net 4.5 和 Microsoft.AspNet.Identity.Core 创建的标识表

Answer 1

Microsoft.AspNetCore.Identity 和 Microsoft.AspNet.Identity.Core 似乎没有很多共同点

Microsoft.AspNet.Identity.Core 和 Microsoft.AspNetCore.Identity 有什么区别？

然而 Microsoft.AspNetCore.Identity 是一个 .net 标准库，因此它应该与 .net core / 5 应用程序兼容

所以你应该尝试在你的 web api 中使用它
