使用外部声明表单OpenId服务器

我正在尝试将Keycloak用作ASP.Net核心应用程序的OpenId服务器。

几乎可以。用户获得了授权(通过[Authorize]属性),但其声明为空。

我的配置:

  services.AddAuthentication(options => { options.DefaultScheme = "cookie"; })
    .AddCookie("cookie")
    .AddOpenIdConnect("oidc", options =>
    {
      options.Authority = "http://localhost:8080/auth/realms/master/";
      options.RequireHttpsMetadata = false;
      options.ClientId = "test-client";
      options.ClientSecret = "ee117d6d-25c9-4317-83a0-54c2f252aa89";
      options.GetClaimsFromUserInfoEndpoint = true;
      options.SaveTokens = true;
      options.RemoteSignOutPath = "/SignOut";
      options.SignedOutRedirectUri = "Redirect-here";
      options.ResponseType = "code";
    });

可以正常运行(获得授权)的控制器动作:

[Authorize]
public IActionResult About()
{
  ViewData["Message"] = "Your application description page.";

  return View();
}

未经授权的控制器操作(因为它需要角色):

[Authorize(Roles = "Administrators")]
public IActionResult About()
{
  ViewData["Message"] = "Your application description page.";

  return View();
}

AccountController.ExternalLoginCallback:

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(); // it has claims
  if (info == null)
  {
    return RedirectToAction(nameof(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
  {
    ViewData["ReturnUrl"] = returnUrl;
    ViewData["LoginProvider"] = info.LoginProvider;
    var email = info.Principal.FindFirstValue(ClaimTypes.Email);
    return View("ExternalLogin", new ExternalLoginViewModel { Email = email });
  }
}
上面摘录中的

info目标具有声明,尤其是角色声明:

enter image description here

但是当我登录并尝试查看角色和蛤lam时,它们是空的:

var user = await _signInManager.UserManager.GetUserAsync(HttpContext.User); // user is found
var roles = await _signInManager.UserManager.GetRolesAsync(user); // empty
var claims = await _signInManager.UserManager.GetClaimsAsync(user); //empty

所以看来Keycloak一切都很好,但是我的应用在使用声明时遇到了问题。

我想念什么?

您需要配置身份验证提供程序,以便它知道要用于角色的声明类型。

您可以对其进行如下配置:

services.AddOpenIdConnect("oidc", options =>
{
    ...

    options.TokenValidationParameters = new TokenValidationParameters
    {
        RoleClaimType = "user_roles"; // or "user_realm_roles"?
    };
});
