Following is a code to get google contacts.
It was working fine but since few days I m getting exception of "Authentication request returned unexpected result: 404".
using Google.GData.Client;
using Google.Contacts;
using Google.GData.Extensions;
private void FetchContactList()
{
List<string> lstContacts = new List<string>();
RequestSettings rsLoginInfo = new RequestSettings("my application", "abc#gmail.com", "XXXXXX");
rsLoginInfo.AutoPaging = true;
ContactsRequest cRequest = new ContactsRequest(rsLoginInfo);
Feed<contact> feedContacts = cRequest.GetContacts();
foreach (Contact gmailAddresses in feedContacts.Entries)
{
// Looping to read email addresses
foreach (EMail emailId in gmailAddresses.Emails)
{
lstContacts.Add(emailId.Address);
}
}
GridView1.DataSource = lstContacts;
GridView1.DataBind();
}
Is google change something from their side?
Please suggest me way to solve the problem.
Update your current api with google api to version 3 and then make changes to the code according. Probably this may be the reason for the error.
https://developers.google.com/analytics/devguides/reporting/core/v3/gdataLibraries
i further suggest you use oauth2.0 for authentication as per the current requirements of your application and if you are using the older version of the api then you must use oauth2.0
Here is the link for oauth2.0 support: https://developers.google.com/google-apps/spreadsheets/authorize
though this is basically for spreadsheets but you can see how it is and working and change it to the requirements of your gmail api

This is the data that is being send by alexa to my skills backend. In the backend code I would like to test if the session is new or not and based on this information I would like to produce a different output. I try to access the session.new, but I don't know how and I could now find anything about it online so far.
const { attributesManager } = handlerInput;
const requestAttributes = attributesManager.getRequestAttributes();
requestAttributes.session.new
//this leads to the error "cannot read property new of undefined"
const { attributesManager } = handlerInput;
const requestAttributes = attributesManager.getSessionAttributes();
sessionAttributes.session.new
//this leads to the same error
I finally found out that this is not possible using the AttributesManager because this only allows access to request, session and permanent attributes. But session.new is not part of those. If you want to check if the Alexa session is new you have to use the so called RequestEnvelopeUtils.
Using those you can access if the session is new or not by using the following statement.
(Alexa.isNewSession(handlerInput.requestEnvelope))
I have security working fine in an application, except when a user tries to login with a '+' in their email.
The access token looks fine (when the email contains a + it looks like this):
Bearer 8BGpt_KkEp-_6U5tUdKqK1xLCQBaWzHcxDT9RRKkbzoF2fHCUNhRL3U-fpLdQIuSXm8RcTOH4ZY3a0UZH6-6IgXxx_ojgyL26179JovRm5xQSZD7ANxLvvdU3ubfcpzSr4tw-sza37UaJh7xDFB8eH0NA9Djt7Ik8Ebxdin7u-n76InCulRAV6xMWgXfF9bwoU8MsV3lrh_zhnxYGnx3O7QUNQ740NUJLHJYH12rBth16CA1AXSF86rA5rUB7vJ7yK09k_FJTifyuldTeFHJHsyscnEIQxGozbf3x1cmZowkiK4Q1r8W0M8uz25m8j_tuMrWawTqYJNZiTuI9afW38WWQ4BRLkQF7TwoMOgZQ-f1K_3W8Zy3x-OsKdQS4i9CapvKe1utCscZVroByvyD9SvpILGiZGTjGD_zCAm8KerMPT5GNOb07kPGV_167PHEXm0TGaJbCelb5gLgXbMXv3GxBQLnYIfPUXCBaKx4UFkY8kFMPs9MxFcGY81p67rfnjeswBZ3PW6fDFTf9U_I8g
However, when I try to send a secure request with this access token, I get the response:
status: 401
"{"Message":"Authorization has been denied for this request."}"
As said above, it works without any issue if I remove the plus. This seems to be a Wep API issue rather than an Angular issue.
I found that the methods encodeUrl and decodeUrl to not stop the space from being change to a plus. I have tried the following in the c# code to switch the space to a plus:
var registerEmail = model.email.Replace(' ', '+');
This is used in both the login and register actions.
Perhaps it is not possible to use a + in an email in OAuth in Web API 2?
It seems to be a bug in asp.net roles. I am not sure of a clear solution. However, for the time being, encoding the username as follows before storing it on register and when logging in:
public static class UsernameEncodingService
{
public static string returnEncodedUsername(string email)
{
var emailAsLower = email.ToLowerInvariant();
var encodedEmail = Base64Encode(emailAsLower);
var encodedEmailWithoutEquals = encodedEmail.Replace("=", "213");
var encodedEmailWithoutPlus = encodedEmailWithoutEquals.Replace("+", "214");
return encodedEmailWithoutEquals;
}
private static string Base64Encode(string plainText)
{
var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(plainText);
return System.Convert.ToBase64String(plainTextBytes);
}
}
I have an unity app and use the google-play-games plugin with google *.aar versions 9.4.0. I lately changed my Backend (Google App Engine) from php to java. My problem is the following: in php the serverauthcode is used to get the users data (in JWT format) - it was working fine. So I changed to a Java servlet and I am failing since 2 days to get a valid idtoken. I am able to recieve the server auth code from my app and a valid token response is made by GoogleAuthorizationCodeTokenRequest (see code snippet). Unfortunately it does not contain any idtoken content but a valid auth_token. So I can not get the user id to identifiy the user. When I call tokenResponse.parseIdToken(); it is failing with a NullPointerException.
servlet code (authCode is the serverAuthCode I send from the play-games-plugin inside Unity to my GAE):
// (Receive authCode via HTTPS POST)
// Set path to the Web application client_secret_*.json file you downloaded from the
// Google Developers Console: https://console.developers.google.com/apis/credentials?project=_
// You can also find your Web application client ID and client secret from the
// console and specify them directly when you create the GoogleAuthorizationCodeTokenRequest
// object.
String CLIENT_SECRET_FILE = "/mypath/client_secret.json";
// Exchange auth code for access token
GoogleClientSecrets clientSecrets =
GoogleClientSecrets.load(
JacksonFactory.getDefaultInstance(), new FileReader(CLIENT_SECRET_FILE));
GoogleTokenResponse tokenResponse =
new GoogleAuthorizationCodeTokenRequest(
new NetHttpTransport(),
JacksonFactory.getDefaultInstance(),
clientSecrets.getDetails().getTokenUri(),
clientSecrets.getDetails().getClientId(),
clientSecrets.getDetails().getClientSecret(),
authCode,
REDIRECT_URI) // Specify the same redirect URI that you use with your web
// app. If you don't have a web version of your app, you can
// specify an empty string.
.execute();
String accessToken = tokenResponse.getAccessToken();
// Get profile info from ID token -> HERE IT THROWS AN EXCEPTION.
GoogleIdToken idToken = tokenResponse.parseIdToken();
GoogleIdToken.Payload payload = idToken.getPayload();
String userId = payload.getSubject(); // Use this value as a key to identify a user.
String email = payload.getEmail();
boolean emailVerified = Boolean.valueOf(payload.getEmailVerified());
String name = (String) payload.get("name");
String pictureUrl = (String) payload.get("picture");
String locale = (String) payload.get("locale");
String familyName = (String) payload.get("family_name");
String givenName = (String) payload.get("given_name");
the token response looks like (its invalid now):
{
"access_token" : "ya29.CjA8A7O96w-vX4OCSPm-GMEPGVIEuRTeOxKy_75z6fbYVSXsdi9Ot3NmxlE-j_t-BI",
"expires_in" : 3596,
"token_type" : "Bearer"
}
In my PHP GAE I always had a idToken inside this constuct which contained my encrypted data. But it is missing now?! So I asssume I do somthing differently in Java or I made a mistake creating the new OAuth 2.0 Client on the google console.
I checked the accessToken manually via:
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=ya29.CjA8A7O96w-vX4OCSPm-GMEPGVIEu-RTeOxKy_75z6fbYVSXsdi9Ot3NmxlE-j_t-BI
{
"issued_to": "48168146---------.apps.googleusercontent.com",
"audience": "48168146---------.apps.googleusercontent.com",
"scope": "https://www.googleapis.com/auth/games_lite",
"expires_in": 879,
"access_type": "offline"
}
Is there something I do not see? Help is very much appreciated...
I found a root cause discussion inside the unity plugin "play-games-services" on github:
https://github.com/playgameservices/play-games-plugin-for-unity/issues/1293
and
https://github.com/playgameservices/play-games-plugin-for-unity/issues/1309
It seems that google switching their authentication flow. In the given links they are talking about adding the email scope inside the plugin to get the idtoken again. I'll try that in the next days and share my experience.
Here is a good explaination about what happens:
http://android-developers.blogspot.de/2016/01/play-games-permissions-are-changing-in.html
If you do what paulsalameh said here (Link to Github) it will work again:
paulsalameh: Sure. After you import the unitypackage, download NativeClient.cs and
PlayGamesClientConfig.cs from my commits (#1295 & #1296), and replace
them in the correct locations.
Afte that "unity play-services-plugin" code update you will be able to add AddOauthScope("email") to PlayGamesClientConfiguration, which allows your server to get the idtoken with the serverAuthCode again...
Code snippet from Unity:
PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder()
.AddOauthScope("email")
.AddOauthScope("profile")
.Build();
Now I am back in business:
{
"access_token" : "ya29.Ci8..7kBR-eBdPw1-P7Pe8QUC7e_Zv7qxCHA",
"expires_in" : 3600,
"id_token" : "eyJhbGciOi......I1NiE0v6kqw",
"refresh_token" : "1/HlSZOo......dQV1y4E",
"token_type" : "Bearer"
}
I am using iOS 6 Social framework for accessing user's Facebook data. I am trying to get likes of the current user within my app using ACAccount and SLRequest. I have a valid Facebook account reference of type ACAccount named facebook, and I'm trying to get user's likes this way:
SLRequest *req = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:url parameters:nil];
req.account = facebook;
[req performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
//my handler code.
}
where url is #"https://graph.facebook.com/me/likes?fields=name"; In my handler, I'm getting this response:
{
error = {
code = 2500;
message = "An active access token must be used to query information about the current user.";
type = OAuthException;
};
}
Shouldn't access tokens be handled by the framework? I've found a similar post Querying Facebook user data through new iOS6 social framework but it doesn't make sense to hard-code an access token parameter into the URL, as logically the access token/login checking should be handled automatically by the framework. In all examples that I've seen around no one plays with an access token manually:
http://damir.me/posts/facebook-authentication-in-ios-6
iOS 6 Facebook posting procedure ends up with "remote_app_id does not match stored id" error
etc.
I am using the iOS6-only approach with the built in Social framework, and I'm not using the Facebook SDK. Am I missing something?
Thanks,
Can.
You need to keep a strong reference to the ACAccountStore that the account comes from. If the store gets deallocated, it looks like it causes this problem.
Try running on an actual device instead of a simulator. This worked for me.
Ensure that your bundle id is input into your Facebook app's configuration. You might have a different bundle id for your dev/debug build.
I am developing an application for Windows Phone 7. I am trying to use services which are provided by the web site I am trying to get information from. I am using an asynchronous request. So if I try to get information from a web site without any authentication I use this code:
EventSrv.EventSrvSoapClient client = new EventSrv.EventSrvSoapClient();
client.GetAppointmentsAsync();
client.GetAppointmentsCompleted += new EventHandler<EventSrv.GetAppointmentsCompletedEventArgs>(events_completed);
and it works fine. But as soon as I want to use a service from a web site which requires authentication I get a
CommunicationException: _innerException:"Server returned an error: Not Found"
at
public L2P.DocumentsService.GetDocumentsResponse EndGetDocuments(System.IAsyncResult result)
{
object[] _args = new object[0];
//Between this line
L2P.DocumentsService.GetDocumentsResponse _result = ((L2P.DocumentsService.GetDocumentsResponse)(base.EndInvoke("GetDocuments", _args, result)));
//and this line
return _result;
}
I am passing the credentials the following way:
DocumentsService.BaseServiceSoapClient docClient = new DocumentsService.BaseServiceSoapClient();
docClient.ClientCredentials.UserName.UserName = Variables.username;
docClient.ClientCredentials.UserName.Password = Variables.password;
docClient.GetDocumentsCompleted += new EventHandler<DocumentsService.GetDocumentsCompletedEventArgs>(getDocumentsCompleted);
docClient.GetDocumentsAsync();
It actually doesn't matter if I pass the credentials or not, I get the same exception. I don't really know what the problem is, maybe it has nothing to do with the authentication. I've read all the articles here on CommunicationException but they couldn't solve my problem.
Any help will be appreciated!
I've finally figured it out! The server uses Basic Authentication and the header is set to "POST" by default. So I needed to modify the Header, set it to "Basic" and add the credentials as well. Furthermore the
CommunicationException: "Server returned an error: Not Found"
always appear if there is any unhandled exception. So you need to debug and check the _innerException for more information.
