ASP.NET core 2 如何跳过身份关联表？

Question

我有一个简单的 ASP.NET 应用程序，我正在尝试允许用户使用外部身份验证提供程序登录。到目前为止，我已经设法实现了 google 身份验证，但是，登录后需要用户确认电子邮件。我想跳过这一步。

我试过使用配置

 services.AddIdentity<ApplicationUser, IdentityRole>(config =>
                    {
                        config.SignIn.RequireConfirmedEmail = false;
                    })
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

但没有运气。我还尝试修改 ExternalLoginCallback 和 ExternalLoginConfirmation 但是我总是把它搞得更糟。

谁能如此友善并分享我必须使用的实际代码，以便在无需确认他的电子邮件的情况下创建新用户？

要跳过电子邮件关联过程，您可以将 ExternalLoginCallback 修改为:

[HttpGet]
[AllowAnonymous]
public async Task<IActionResult> ExternalLoginCallback(string returnUrl = null, string remoteError = null)
{
    if (remoteError != null)
    {
        ErrorMessage = $"Error from external provider: {remoteError}";
        return RedirectToAction(nameof(Login));
    }
    var info = await _signInManager.GetExternalLoginInfoAsync();
    if (info == null)
    {
        return RedirectToAction(nameof(Login));
    }

    // Sign in the user with this external login provider if the user already has a login.
    var result = await _signInManager.ExternalLoginSignInAsync(info.LoginProvider, info.ProviderKey, isPersistent: false, bypassTwoFactor: true);
    if (result.Succeeded)
    {
        _logger.LogInformation("User logged in with {Name} provider.", info.LoginProvider);
        return RedirectToLocal(returnUrl);
    }
    if (result.IsLockedOut)
    {
        return RedirectToAction(nameof(Lockout));
    }
    else
    {
        var userEmail = info.Principal.Claims.FirstOrDefault(x => x.Type == ClaimTypes.Email).Value.ToString();
        var user = new ApplicationUser { UserName = userEmail, Email = userEmail };
        var resultCreateUser = await _userManager.CreateAsync(user);
        if (resultCreateUser.Succeeded)
        {
            var resultAddLogin = await _userManager.AddLoginAsync(user, info);
            if (resultAddLogin.Succeeded)
            {
                await _signInManager.SignInAsync(user, isPersistent: false);
                _logger.LogInformation("User created an account using {Name} provider.", info.LoginProvider);
                return RedirectToLocal(returnUrl);
            }
        }

    }

    // If the user does not have an account, then ask the user to create an account.
    ViewData["ReturnUrl"] = returnUrl;
    ViewData["LoginProvider"] = info.LoginProvider;
    var email = info.Principal.FindFirstValue(ClaimTypes.Email);
    return View("ExternalLogin", new ExternalLoginViewModel { Email = email });
}

这将跳过关联表单并自动使用外部用户的电子邮件名称。
