Sign in with Apple in .Net MAUI

I am currently working on an dotnet maui app and I need to integrate Sign in With Apple. But when I click the sign in button, It shows "invalid_request invalid web redirect url"
Tried solutions
I tried the solutions available here, but it is not working.
Other than that I have also read the documentation, also got help from tutorials such as this, this and this
Code
Initializing request:
//Initiating apple sign in request
WebAuthenticatorResult result = null;
if (scheme.Equals(Constants.apple, StringComparison.Ordinal)
&& DeviceInfo.Platform == DevicePlatform.iOS
&& DeviceInfo.Version.Major >= 13)
{
// Make sure to enable Apple Sign In in both the
// entitlements and the provisioning profile.
var options = new AppleSignInAuthenticator.Options
{
IncludeEmailScope = true,
IncludeFullNameScope = true,
};
result = await AppleSignInAuthenticator.AuthenticateAsync(options);
}
else
{
var authUrl = new Uri(Constants.authenticationUrl + scheme);
var callbackUrl = new Uri(Constants.callbackUrl);
result = await WebAuthenticator.AuthenticateAsync(authUrl, callbackUrl);
}
AuthToken = string.Empty;
// Get Name and Email from callback url
//if (result.Properties.TryGetValue("name", out var name) && !string.IsNullOrEmpty(name))
// AuthToken += $"Name: {name}{Environment.NewLine}";
//if (result.Properties.TryGetValue("email", out var email) && !string.IsNullOrEmpty(email))
// AuthToken += $"Email: {email}{Environment.NewLine}";
AuthToken += result?.AccessToken ?? result?.IdToken;
AuthCredential credential = null;
Handling results:
// WebAuthenticator Endpoint - use for social login e.g. Google, Facebook, Apple etc.
const string callbackScheme = "socialloginauthenticator";
[HttpGet("{scheme}")]
public async Task Get([FromRoute] string scheme)
{
var auth = await Request.HttpContext.AuthenticateAsync(scheme);
if (!auth.Succeeded
|| auth?.Principal == null
|| !auth.Principal.Identities.Any(id => id.IsAuthenticated)
|| string.IsNullOrEmpty(auth.Properties.GetTokenValue("access_token")))
{
// Not authenticated, challenge
await Request.HttpContext.ChallengeAsync(scheme);
}
else
{
var claims = auth.Principal.Identities.FirstOrDefault()?.Claims;
var email = string.Empty;
email = claims?.FirstOrDefault(c => c.Type == System.Security.Claims.ClaimTypes.Email)?.Value;
// Get parameters to send back to the callback
var qs = new Dictionary<string, string>
{
{ "access_token", auth.Properties.GetTokenValue("access_token") },
{ "refresh_token", auth.Properties.GetTokenValue("refresh_token") ?? string.Empty },
{ "expires_in", (auth.Properties.ExpiresUtc?.ToUnixTimeSeconds() ?? -1).ToString() },
{ "email", email }
};
// Build the result url
var url = callbackScheme + "://#" + string.Join(
"&",
qs.Where(kvp => !string.IsNullOrEmpty(kvp.Value) && kvp.Value != "-1")
.Select(kvp => $"{WebUtility.UrlEncode(kvp.Key)}={WebUtility.UrlEncode(kvp.Value)}"));
// Redirect to final url
Request.HttpContext.Response.Redirect(url);
}
}

I have resolved the issue. The issue was with redirect uri in apple service I made.
The required uri was of format "www.example.com/signin-apple" while I was following "www.example.com/path/to/endpoints"

Microsoft Identity Platform - User Token Cache args.Account is always null

I have an MVC web application wanting to send emails from one email address using Office365. I am calling the API so that it shows up the microsoftonline login page for signing in. On successful sign in I am receiving the code back from API and generating Microsoft.Identity.Client.AuthenticationResult with the help of code and saving tokenresponse.UniqueId and tokenresponse.Account.HomeAccountId.Identifier in database.
I got to following page and signed in successfully and my database has the response saved.
After this I am trying to send emails using following code:
IConfidentialClientApplication mailer;
var mailerbuilder = ConfidentialClientApplicationBuilder
.Create(o365setpQry.ClientId))
.WithAuthority(AzureCloudInstance.AzurePublic, o365setpQry.Tenant)
.WithClientSecret(o365setpQry.ClientSecret);
mailerbuilder.WithRedirectUri(O365OAuthRedirectURL);
mailer = mailerbuilder.Build();
//user token cache.
mailer.UserTokenCache.SetAfterAccess((args) => {
Users user;
if **(args.Account == null)** user = null;
else user = _users.Table.Where(x => x.email_address == args.Account.Username).FirstOrDefault();
if (user == null)
{
var emsetp = _emsetp.Table.FirstOrDefault();
if (args.HasStateChanged || (emsetp.o365_GlobalTokenInfo == null))
{
emsetp.o365_GlobalTokenInfo = args.TokenCache.SerializeMsalV3();
}
}
else if (args.HasStateChanged || (user.o365_TokenInfo == null))
{
user.o365_TokenInfo = args.TokenCache.SerializeMsalV3();
_users.Update(user);
}
});
webEmailer.UserTokenCache.SetBeforeAccess((args) => {
Users user;
**if (args.Account == null)** user = null;
else user = _users.Table.Where(x => x.email_address == args.Account.Username).FirstOrDefault();
if (user == null)
{
args.TokenCache.DeserializeMsalV3(_emsetp.Table.FirstOrDefault().o365_GlobalTokenInfo);
}
else if (user.o365_TokenInfo != null)
{
args.TokenCache.DeserializeMsalV3(user.o365_TokenInfo);
}
});
var t = mailer.GetAccountAsync(emsetp.FirstOrDefault().o365_GlobalToken);
t.Wait();
Microsoft.Identity.Client.IAccount acct = t.Result;
The args.Account is returning null always.
var RequestClient = GraphClientFactory.Create(new DelegateAuthenticationProvider(new AuthenticateRequestAsyncDelegate((args) => {
var tokenRequest = mailer.AcquireTokenSilent(scopes, acct).ExecuteAsync();
tokenRequest.Wait();
args.Headers.Authorization = new AuthenticationHeaderValue("Bearer", tokenRequest.Result.AccessToken);
return System.Threading.Tasks.Task.FromResult(0);
})));
var graphClient = new GraphServiceClient(RequestClient);
var t = graphClient.Me.SendMail(message, true).Request();
var u = t.PostAsync();
I made sure my redirect urls are matching and I am not getting any errors from the API calls to see what is wrong and what makes args.Account value null and thus am not able to send emails. If I request the sign in page again it still shows the account I am signed in with.

Get all followings using LINQ to Twitter

I've just started a Windows Phone app, and I need to get all the user's followings.
I tried this :
SharedState.Authorizer = pinAuth;
ITwitterAuthorizer auth = SharedState.Authorizer;
TwitterContext twitterCtx = new TwitterContext(auth);
var friendList =
(from friend in twitterCtx.SocialGraph
where friend.Type == SocialGraphType.Friends && friend.ScreenName == "_TDK"
select friend)
.SingleOrDefault();
List<String> Followings;
foreach (var id in friendList.ScreenName)
{
Followings.Add(id.ToString());
}
But friendlist is always null and, obviously, the foreach does not like that and throws an exception.
Could someone help me ?
Thanks.

I think you need to iterate over the IDs collection, like this:
foreach (var id in friendList.IDs)
{
Followings.Add(id.ToString());
}
You need to make async calls with Silverlight-based apps, including Windows Phone. Here's an example of how you can refactor the query:
var twitterCtx = new TwitterContext(auth);
(from social in twitterCtx.SocialGraph
where social.Type == SocialGraphType.Followers &&
social.ScreenName == "JoeMayo"
select social)
.MaterializedAsyncCallback(asyncResponse =>
Dispatcher.BeginInvoke(() =>
{
if (asyncResponse.Status != TwitterErrorStatus.Success)
{
MessageBox.Show(
"Error during query: " +
asyncResponse.Exception.Message);
return;
}
SocialGraph social = asyncResponse.State.SingleOrDefault();
SocialListBox.ItemsSource = social.IDs;
}));
The MaterializedAsyncCallback manages the callback from Twitter. Notice how I use Dispatcher.BeginInvoke to marshal the call back onto the UI thread as the callback is on a worker thread. On the asyncResponse callback parameter, use Status to see if there is an error and use State to get the data if the query is successful.

I had the same problem, I solved this way (I know it's not the best way)
public void getProfile(MyProgressBar myprogressbar)
{
var auth = new SingleUserAuthorizer
{
Credentials = new InMemoryCredentials
{
ConsumerKey = GlobalVariables.ConsumerKey,
ConsumerSecret = GlobalVariables.ConsumerSecret,
AccessToken = GlobalVariables.AccessToken,
OAuthToken = GlobalVariables.AccessTokenSecret
}
};
using (var twitterCtx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"))
{
//Log
twitterCtx.Log = Console.Out;
var queryResponse = (from tweet in twitterCtx.Status
where tweet.Type == StatusType.User && tweet.ScreenName == GlobalVariables.ScreenName
select tweet);
queryResponse.AsyncCallback(tweets =>
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
var publicTweets = (from tweet in tweets
select tweet).FirstOrDefault();
s.TwitterName = publicTweets.User.Name.ToString();
s.TwitterScreenName = "#" + GlobalVariables.ScreenName;
s.TwitterDescription = publicTweets.User.Description.ToString();
s.TwitterStatus = publicTweets.User.StatusesCount.ToString() + " Tweets / " + publicTweets.User.FriendsCount.ToString() + " Following / " + publicTweets.User.FollowersCount.ToString() + " Followers";
s.TwitterImage = publicTweets.User.ProfileImageUrl.ToString();
myprogressbar.ShowProgressBar = false;
})).SingleOrDefault();
}
}

Get user info after authentication using LINQ to Twitter

I want to retrieve user info after authentication with Twitter. For this purpose I'm using LINQ to Twitter library. It's possible to do with this code:
var usersResponse =
(from user in context.User
where user.Type == UserType.Lookup &&
user.ScreenName == "MRade90"
select user).ToList();
var users =
(from user in usersResponse
select new User
{
Name = user.Identifier.ScreenName,
StatusText = user.Status.Text,
PictureUrl = new Uri(user.ProfileImageUrl)
}).FirstOrDefault();
But this is hardcoded with ScreenName set to MRade90. Is it possible to do the same thing for currently authenticated user?

I found it. The current user credentials can be accessed from Credentials property of WinRtAuthorizer class. For example you can use ScreenName like here:
string screenName = auth.Credentials.ScreenName;

I am using
var users =
(from user in twitterCtx1.User
where user.Type == UserType.Lookup &&
//user.UserID == list1
list1.Contains(user.UserID)
select user)
.ToList();
However, I am not able to extract the user IDs and work . Any inputs where I might be going wrong.
Thanks

This is how I do this,
var auth = new SingleUserAuthorizer
{
CredentialStore = new SingleUserInMemoryCredentialStore
{
ConsumerKey = consumerKey,
ConsumerSecret = consumerSecret,
AccessToken = twitterToken.Token,
AccessTokenSecret = twitterToken.TokenSecret
}
};
var twitterCtx = new TwitterContext(auth);
var acc = (from user in twitterCtx.Account where user.Type == AccountType.VerifyCredentials select user).FirstOrDefault();

How can I tell if a webproperty is deleted using Google AnalyticsService?

I am using the Google Analytics Api to get web property information from my Analytics account.
When I log into analaytics though, I only have one website, but through the api I get several (old and deleted sites)
My code is like this:
var provider = new WebServerClient(GoogleAuthenticationServer.Description)
{
ClientIdentifier = _appId,
ClientSecret = _appSecret
};
var auth = new OAuth2Authenticator<WebServerClient>(provider, x => new AuthorizationState { AccessToken = token });
var analyticsService = new AnalyticsService(auth);
var accounts = analyticsService.Management.Accounts.List().Fetch();
foreach (var account in accounts.Items)
{
var webProperties = analyticsService.Management.Webproperties.List(account.Id).Fetch();
// todo: determine if web property is still in use?
}
From code how can I tell which ones are still active?

So after a bit more digging.
It seems there is no flag or anything like that indicating it has been removed, but if you keep digging into the result set you will notice that at the profile level, a profile that doesn't have child items seems to be a deleted one.
Which makes sense I guess there wouldn't be a profile associated with those that have been removed.
var provider = new WebServerClient(GoogleAuthenticationServer.Description)
{
ClientIdentifier = _appId,
ClientSecret = _appSecret
};
var auth = new OAuth2Authenticator<WebServerClient>(provider, x => new AuthorizationState { AccessToken = token });
var analyticsService = new AnalyticsService(auth);
var accounts = analyticsService.Management.Accounts.List().Fetch();
var result = new List<Profile>();
foreach (var account in accounts.Items)
{
var webProperties = analyticsService.Management.Webproperties.List(account.Id).Fetch();
foreach (var webProperty in webProperties.Items)
{
var profiles = analyticsService.Management.Profiles.List(account.Id, webProperty.Id).Fetch();
if (profiles.Items != null && profiles.Items.Any())
{
// these are the ones we want
result.AddRange(profiles.Items);
}
}
}
}
