ASP.NET 核心 2 如何跳过身份关联表单

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，我已经设法实现了谷歌身份验证，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 config

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

但没有运气。我也试图修改ExternalLoginCallback和ExternalLoginConfirmation，但我总是把它搞砸得更厉害。

任何人都可以如此友善地分享我必须使用的实际代码来创建新用户而无需确认他的电子邮件吗？

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。
