今天我試圖在我的項目上實現外部Facebook登錄。 但是,當我嘗試登錄調用ExternalLogin的方法,這個方法不返回給Facebook登錄頁面C# - Owin Oauth不重定向到外部登錄頁面
我試着這樣做: https://coding.abel.nu/2014/06/understanding-the-owin-external-authentication-pipeline/
當我看到我的背景下,AuthenticationResponseChallenge爲空。
按照代碼:
Startup.Auth.cs
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
var fao = new FacebookAuthenticationOptions
{
AppId = APP_ID_FACEBOOK, //on Web.config
AppSecret = APP_SECRET_FACEBOOK //on Web.config
};
fao.Scope.Add("email");
fao.Scope.Add("basic_info");
fao.Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = (context) =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("urn:facebook:access_token", context.AccessToken, XmlSchemaString, "Facebook"));
foreach (var x in context.User)
{
var claimType = string.Format("urn:facebook:{0}", x.Key);
string claimValue = x.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, XmlSchemaString, "Facebook"));
}
return Task.FromResult(0);
}
};
fao.SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie;
app.UseFacebookAuthentication(fao);
AccountController.cs
public ActionResult ExternalLogin(string provider, string returnUrl)
{
var result = new ChallengeResult(provider, Url.Action("ExternalLoginCallback", "Conta", new { ReturnUrl = returnUrl }));
return result;
}
private const string XsrfKey = "XsrfId";
internal class ChallengeResult : HttpUnauthorizedResult
{
public ChallengeResult(string provider, string redirectUri)
: this(provider, redirectUri, null)
{
}
public ChallengeResult(string provider, string redirectUri, string userId)
{
LoginProvider = provider;
RedirectUri = redirectUri;
UserId = userId;
}
public string LoginProvider { get; set; }
public string RedirectUri { get; set; }
public string UserId { get; set; }
public override void ExecuteResult(ControllerContext context)
{
var properties = new AuthenticationProperties { RedirectUri = RedirectUri };
if (UserId != null)
{
properties.Dictionary[XsrfKey] = UserId;
}
context.HttpContext.GetOwinContext().Authentication.Challenge(properties, LoginProvider);
}
}
我試圖用我的Facebook應用程序憑據創建一個空的項目和工作正常,但在這個項目中這不起作用
任何人都可以幫助我嗎?
你的意思是什麼不起作用?你能解釋一下嗎? –
