I have seen many posts for facebook authentication , either those are old or not working correctly as it should be.
However finally I have made something in my project that works but not fully. Here is code where I ask for
var facebookAuthenticationOptions = new FacebookAuthenticationOptions()
{
AppId = "...ID",
AppSecret = "...AppSecret",
AuthenticationType = "Facebook",
SignInAsAuthenticationType = "ExternalCookie",
//Provider = new FacebookAuthenticationProvider
//{
// OnAuthenticated = async ctx =>
// {
// if (ctx.User["birthday"] != null)
// {
// ctx.Identity.AddClaim(new Claim(ClaimTypes.DateOfBirth,ctx.User["birthday"].ToString()));
// }
// }
//}
};
facebookAuthenticationOptions.Scope.Add("user_birthday");
//facebookAuthenticationOptions.Scope.Add("first_name");
//facebookAuthenticationOptions.Scope.Add("last_name");
//page goes blank if ask for first_name,last_name , if comment out works
//but doesn give date of birth or likes or other things.
facebookAuthenticationOptions.Scope.Add("publish_stream");
facebookAuthenticationOptions.Scope.Add("user_likes");
facebookAuthenticationOptions.Scope.Add("friends_likes");
facebookAuthenticationOptions.Scope.Add("read_stream");
facebookAuthenticationOptions.Scope.Add("email");
app.UseFacebookAuthentication(facebookAuthenticationOptions);
Can anyone please help me why I am not getting friends_like,birthday, user_likes and so on.
In addition, how to get those string values(ie. "user_birthday","first_name") for information retrieval, like how would I know that "user_birthday" returns date of birthday(I got it from searching) , is there any list which have this string names(ie. "user_birthday","first_name") ?
If I use google authentication is it possible to get phone number or first name,last name?
Solved it, References there : https://developers.facebook.com/docs/facebook-login/permissions/v2.1#reference
var facebookAuthenticationOptions = new FacebookAuthenticationOptions() {
AppId = ".....",
AppSecret = ".....",
AuthenticationType = "Facebook",
SignInAsAuthenticationType = "ExternalCookie",
Provider = new FacebookAuthenticationProvider {
OnAuthenticated = async ctx => {
ctx.Identity.AddClaim(new Claim(ClaimTypes.DateOfBirth, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.Country, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.Gender, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.MobilePhone, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.OtherPhone, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.HomePhone, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.StateOrProvince, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.Email, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.Country, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.Actor, ctx.User["birthday"].ToString()));
ctx.Identity.AddClaim(new Claim(ClaimTypes.DateOfBirth, ctx.User["birthday"].ToString()));
}
}
};
facebookAuthenticationOptions.Scope.Add("user_birthday");
//facebookAuthenticationOptions.Scope.Add("first_name");
//facebookAuthenticationOptions.Scope.Add("last_name");
facebookAuthenticationOptions.Scope.Add("publish_stream");
facebookAuthenticationOptions.Scope.Add("user_likes");
facebookAuthenticationOptions.Scope.Add("friends_likes");
facebookAuthenticationOptions.Scope.Add("user_about_me");
facebookAuthenticationOptions.Scope.Add("user_friends");
facebookAuthenticationOptions.Scope.Add("user_actions.news");
facebookAuthenticationOptions.Scope.Add("user_actions.video");
facebookAuthenticationOptions.Scope.Add("user_education_history");
facebookAuthenticationOptions.Scope.Add("manage_pages");
facebookAuthenticationOptions.Scope.Add("user_interests");
facebookAuthenticationOptions.Scope.Add("user_location");
facebookAuthenticationOptions.Scope.Add("user_photos");
facebookAuthenticationOptions.Scope.Add("user_relationships");
facebookAuthenticationOptions.Scope.Add("user_relationship_details");
facebookAuthenticationOptions.Scope.Add("user_status");
facebookAuthenticationOptions.Scope.Add("user_tagged_places");
facebookAuthenticationOptions.Scope.Add("user_videos");
facebookAuthenticationOptions.Scope.Add("user_website");
facebookAuthenticationOptions.Scope.Add("read_friendlists");
facebookAuthenticationOptions.Scope.Add("read_stream");
facebookAuthenticationOptions.Scope.Add("email");
app.UseFacebookAuthentication(facebookAuthenticationOptions);
ctx got all the information.. Just have to go through it.
Still don't have information on how to get google first,last name and phone number + date of birth. Or how to access user contacts from gmail account.
You can just loop through context.User to get all claims
var facebookAuthOptions = new FacebookAuthenticationOptions();
facebookAuthOptions.AppId = "..."; //Enter your AppId
facebookAuthOptions.AppSecret = "..."; //Enter your AppSecret
facebookAuthOptions.Provider = new FacebookAuthenticationProvider()
{
OnAuthenticated = async context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("FacebookAccessToken", context.AccessToken));
foreach (var claim in context.User)
{
var claimType = string.Format("urn:facebook:{0}", claim.Key);
string claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Facebook"));
}
}
};
The same goes for Google
var googleAuthOptions = new GoogleOAuth2AuthenticationOptions();
googleAuthOptions.ClientId = "..."; //Enter your ClientId
googleAuthOptions.ClientSecret = "..."; //Enter your ClientSecret
googleAuthOptions.Provider = new GoogleOAuth2AuthenticationProvider()
{
OnAuthenticated = async context =>
{
context.Identity.AddClaim(new System.Security.Claims.Claim("GoogleAccessToken", context.AccessToken));
foreach (var claim in context.User)
{
var claimType = string.Format("urn:google:{0}", claim.Key);
string claimValue = claim.Value.ToString();
if (!context.Identity.HasClaim(claimType, claimValue))
context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Google"));
}
}
};
And I think User's privacy settings and your application permissions control which claims you can get.
