[英]Why sign-in a new user when using ASP.NET Core Identity and token-based auth?
[英]InvalidOperationException when registering a new user with ASP .NET Core Identity and EntityFrameworkCore
我正在遵循使用身份的文檔,並嘗試注冊一個新用戶(執行register操作),但是失敗並出現以下錯誤:
InvalidOperationException:無法為'ApplicationUser'創建DbSet,因為此類型不包含在上下文模型中。
啟動:
services.AddIdentity<ApplicationUser, IdentityRole>(options =>
{
//password options
options.Password.RequireDigit = false;
// ...
})
我正在使用標准的ApplicationUser:
public class ApplicationUser : IdentityUser
{
}
在AccountController中注冊操作:
public async Task<IActionResult> Register(RegisterViewModel viewModel)
{
if (ModelState.IsValid)
{
var user = new ApplicationUser { UserName = viewModel.UserName, Email = viewModel.Email };
var result = await _userManager.CreateAsync(user, viewModel.Password); //<-- Exception happens here
if (result.Succeeded)
{
await _signInManager.SignInAsync(user, isPersistent: false);
_logger.LogInformation(3, "User created a new account with password.");
return RedirectToAction(nameof(HomeController.Index), "Home");
}
string errorData = "";
foreach (var error in result.Errors)
{
errorData += error.Description + '\n';
}
StoreErrorMessage("Failed to create the user!", errorData);
}
return View(viewModel);
}
我已經嘗試了以下方法:
DbSet<ApplicationUser>
到AplicationContext
dotnet ef
創建並應用了新的遷移 我發現了問題。 我的ApplicationContext
是從DbContext
繼承的。 我將其更改為IdentityDbContext<ApplicationUser>
,它可以工作。
創建繼承IdentityIbContext的新上下文類。
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
// Customize the ASP.NET Identity model and override the defaults if needed.
// For example, you can rename the ASP.NET Identity table names and more.
// Add your customizations after calling base.OnModelCreating(builder);
}
}
並在startup.cs文件中添加以下代碼
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(connection));
這將幫助您采用數據庫優先方法。
