【问题描述】：
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，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。它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；
我已经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 表似乎带有额外的字段。
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);
}
}
但是我没有收到关于 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'. See https://go.microsoft.com/fwlink/?linkid=2101038 for more information.

虽然它确实提出了解决方案。我不确定在哪里进行更改，因为我自己并没有创建查询，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 创建的身份表
