using getidentity in azure mobile app: easy api - api

Question

I am using following code to get user details in azure mobile services. I am trying to migrate to azure mobile app, and get user details in easy api. how to do that ?
getIdentity({
success: function (identities) {
var req = require('request');
if (identities.facebook) {
var fbAccessToken = identities.facebook.accessToken;
var url = 'https://graph.facebook.com/me?access_token=' + fbAccessToken;
req(url, function (err, resp, body) {
if (err || resp.statusCode !== 200) {
console.error('Error sending data to FB Graph API: ', err);
// req.respond(statusCodes.INTERNAL_SERVER_ERROR, body);
} else {
try {
var userData = JSON.parse(body);
console.log(JSON.parse(userData));
res.json(userData);
//item.UserName = userData.name;
// request.execute();
} catch (ex) {
console.error('Error parsing response from FB Graph API: ', ex);
// request.respond(statusCodes.INTERNAL_SERVER_ERROR, ex);
}
}
});

Following this example, I edited the script and it works for me with google authentication.
currentUser.getIdentity()
.then((data) =>
{
var http = require('request');
var url = 'https://www.googleapis.com/oauth2/v3/userinfo' +
'?access_token=' + data.google.access_token;
var reqParams = {
uri: url, headers: { Accept: 'application/json' } };
http.get(reqParams, function (err, resp, body) {
var userData = JSON.parse(body);
res.status(200).send( {message: userData});
});
}, console.error);

This link advises using the context to request for additional user details in an EasyTable Node.js script instead of an EasyAPI. Only resource I could find that doesn't rely on the classic Azure portal.

Edit: the above code didn't work for me, so maybe this will help anyone else out

It seems like there is a build in function already. below code is invoking .auth/me action on your client and returns you claims object. claims object is a dictionary of information, you selected on azure portal.
public async Task<AppServiceIdentity> GetIdentityAsync()
{
if (Client.CurrentUser == null || Client.CurrentUser?.MobileServiceAuthenticationToken == null)
{
throw new InvalidOperationException("Not Authenticated");
}
if (identities == null)
{
identities = await Client.InvokeApiAsync<List<AppServiceIdentity>>("/.auth/me");
}
if (identities.Count > 0)
return identities[0];
return null;
}
public class AppServiceIdentity
{
[JsonProperty(PropertyName = "id_token")]
public string IdToken { get; set; }
[JsonProperty(PropertyName = "provider_name")]
public string ProviderName { get; set; }
[JsonProperty(PropertyName = "user_id")]
public string UserId { get; set; }
[JsonProperty(PropertyName = "user_claims")]
public List<UserClaim> UserClaims { get; set; }
}
public class UserClaim
{
[JsonProperty(PropertyName = "typ")]
public string Type { get; set; }
[JsonProperty(PropertyName = "val")]
public string Value { get; set; }
}
So you will get the info from claims object like this for name
var name = identity.UserClaims.FirstOrDefault(c => c.Type.Equals("name")).Value;
