How to get email address from twitter - angularjs

Question

The twitter login is used by my app using ionic framework, and i want to get email address from twitter, i have requested twitter and app is now able to get email address.
But somehow the code below is not able to get email address.
For this i have created new function named getTwitterProfileManual but still it is not working.
I have also read document provided by twitter at Doc and as suggested i am also passing include_email params as request query. But still response do not have email address in it.
serviceModule.factory('TwitterService', function ($cordovaOauth, $cordovaOauthUtility, $http, $resource, $q, AUTH_ID)
{
var twitterKey = "STORAGE.TWITTER.KEY";
var clientId = AUTH_ID.TWITTER_APP_ID;
var clientSecret = AUTH_ID.TWITTER_APP_SEC;
function storeUserToken(data)
{
window.localStorage.setItem(twitterKey, JSON.stringify(data));
}
function getStoredToken()
{
return window.localStorage.getItem(twitterKey);
}
function createTwitterSignature(method, url, params)
{
if (!params) {
params = {};
}
var token = angular.fromJson(getStoredToken());
var oauthObject = {
oauth_consumer_key: clientId,
oauth_nonce: $cordovaOauthUtility.createNonce(10),
oauth_signature_method: "HMAC-SHA1",
oauth_token: token.oauth_token,
oauth_timestamp: Math.round((new Date()).getTime() / 1000.0),
oauth_version: "1.0"
};
console.log(JSON.stringify(oauthObject));
var signatureObj = $cordovaOauthUtility.createSignature(method, url, oauthObject, params, clientSecret, token.oauth_token_secret);
$http.defaults.headers.common.Authorization = signatureObj.authorization_header;
console.log(JSON.stringify(signatureObj.authorization_header));
}
return {
initialize: function ()
{
var deferred = $q.defer();
var token = getStoredToken();
if (token !== null)
{
deferred.resolve(true);
}
else
{
$cordovaOauth.twitter(clientId, clientSecret).then(function (result)
{
storeUserToken(result);
deferred.resolve(true);
}, function (error)
{
deferred.reject(false);
});
}
return deferred.promise;
},
isAuthenticated: function ()
{
return getStoredToken() !== null;
},
getHomeTimeline: function ()
{
var home_tl_url = 'https://api.twitter.com/1.1/statuses/home_timeline.json';
createTwitterSignature('GET', home_tl_url);
return $resource(home_tl_url).query();
},
getTwitterProfile: function ()
{
var tl_url = 'https://api.twitter.com/1.1/account/verify_credentials.json';
createTwitterSignature('GET', tl_url);
return $resource(tl_url, {'include_email': true}).query();
},
getTwitterProfileManual: function () {
var deferred = $q.defer();
var token = angular.fromJson(getStoredToken());
createTwitterSignature('GET', 'https://api.twitter.com/1.1/account/verify_credentials.json');
// $http.get("https://api.twitter.com/1.1/account/verify_credentials.json")
$http({
method: 'GET',
url: "https://api.twitter.com/1.1/account/verify_credentials.json",
params : { 'include_email': true }
}).success(function (result)
{
console.log(result);
alert('USER TIMELINE: ' + JSON.stringify(result));
deferred.resolve(result);
}).error(function (error)
{
alert("Error: " + JSON.stringify(error));
deferred.reject(false);
});
return deferred.promise;
},
storeUserToken: storeUserToken,
getStoredToken: getStoredToken,
createTwitterSignature: createTwitterSignature
};
});
Does anyone came across such problem and solved it, if so please provide some hint.

After days of working i finally made it working.
Below is the code for anyone who will face such issue.
Code :
serviceModule.factory('$twitterHelpers', ['$q', '$http', function ($q, $http) {
function createSignature(method, endPoint, headerParameters, bodyParameters, secretKey, tokenSecret) {
if (typeof jsSHA !== "undefined") {
var headerAndBodyParameters = angular.copy(headerParameters);
var bodyParameterKeys = Object.keys(bodyParameters);
for (var i = 0; i < bodyParameterKeys.length; i++) {
headerAndBodyParameters[bodyParameterKeys[i]] = escapeSpecialCharacters(bodyParameters[bodyParameterKeys[i]]);
}
var signatureBaseString = method + "&" + encodeURIComponent(endPoint) + "&";
var headerAndBodyParameterKeys = (Object.keys(headerAndBodyParameters)).sort();
for (i = 0; i < headerAndBodyParameterKeys.length; i++) {
if (i == headerAndBodyParameterKeys.length - 1) {
signatureBaseString += encodeURIComponent(headerAndBodyParameterKeys[i] + "=" + headerAndBodyParameters[headerAndBodyParameterKeys[i]]);
} else {
signatureBaseString += encodeURIComponent(headerAndBodyParameterKeys[i] + "=" + headerAndBodyParameters[headerAndBodyParameterKeys[i]] + "&");
}
}
var oauthSignatureObject = new jsSHA(signatureBaseString, "TEXT");
var encodedTokenSecret = '';
if (tokenSecret) {
encodedTokenSecret = encodeURIComponent(tokenSecret);
}
headerParameters.oauth_signature = encodeURIComponent(oauthSignatureObject.getHMAC(encodeURIComponent(secretKey) + "&" + encodedTokenSecret, "TEXT", "SHA-1", "B64"));
var headerParameterKeys = Object.keys(headerParameters);
var authorizationHeader = 'OAuth ';
for (i = 0; i < headerParameterKeys.length; i++) {
if (i == headerParameterKeys.length - 1) {
authorizationHeader += headerParameterKeys[i] + '="' + headerParameters[headerParameterKeys[i]] + '"';
} else {
authorizationHeader += headerParameterKeys[i] + '="' + headerParameters[headerParameterKeys[i]] + '",';
}
}
return {signature_base_string: signatureBaseString, authorization_header: authorizationHeader, signature: headerParameters.oauth_signature};
} else {
return "Missing jsSHA JavaScript library";
}
}
function createNonce(length) {
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < length; i++) {
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text;
}
function escapeSpecialCharacters(string) {
var tmp = encodeURIComponent(string);
tmp = tmp.replace(/\!/g, "%21");
tmp = tmp.replace(/\'/g, "%27");
tmp = tmp.replace(/\(/g, "%28");
tmp = tmp.replace(/\)/g, "%29");
tmp = tmp.replace(/\*/g, "%2A");
return tmp;
}
function transformRequest(obj) {
var str = [];
for (var p in obj)
str.push(encodeURIComponent(p) + "=" + escapeSpecialCharacters(obj[p]));
console.log(str.join('&'));
return str.join('&');
}
return {
createTwitterSignature: function (method, url, bodyParameters, clientId, clientSecret, token) {
var oauthObject = {
oauth_consumer_key: clientId,
oauth_nonce: createNonce(10),
oauth_signature_method: "HMAC-SHA1",
oauth_token: token.oauth_token,
oauth_timestamp: Math.round((new Date()).getTime() / 1000.0),
oauth_version: "1.0"
};
var signatureObj = createSignature(method, url, oauthObject, bodyParameters, clientSecret, token.oauth_token_secret);
$http.defaults.headers.common.Authorization = signatureObj.authorization_header;
return signatureObj;
},
transformRequest: transformRequest
};
}]);
serviceModule.factory('TwitterService', function ($cordovaOauth, $cordovaOauthUtility, $http, $resource, $q, AUTH_ID, $twitterHelpers)
{
var twitterKey = "STORAGE.TWITTER.KEY";
var clientId = AUTH_ID.TWITTER_APP_ID;
var clientSecret = AUTH_ID.TWITTER_APP_SEC;
function storeUserToken(data)
{
window.localStorage.setItem(twitterKey, JSON.stringify(data));
}
function getStoredToken()
{
return window.localStorage.getItem(twitterKey);
}
return {
initialize: function ()
{
var deferred = $q.defer();
var token = getStoredToken();
if (token !== null)
{
deferred.resolve(true);
}
else
{
$cordovaOauth.twitter(clientId, clientSecret).then(function (result)
{
storeUserToken(result);
deferred.resolve(true);
}, function (error)
{
deferred.reject(false);
});
}
return deferred.promise;
},
isAuthenticated: function ()
{
return getStoredToken() !== null;
},
getHomeTimeline: function ()
{
var home_tl_url = 'https://api.twitter.com/1.1/statuses/home_timeline.json';
createTwitterSignature('GET', home_tl_url);
return $resource(home_tl_url).query();
},
getTwitterProfileManual: function () {
var deferred = $q.defer();
var token = angular.fromJson(getStoredToken());
$twitterHelpers.createTwitterSignature('GET', 'https://api.twitter.com/1.1/account/verify_credentials.json', { 'include_email' : 'true' }, clientId, clientSecret, token);
$http({
method: 'GET',
url: "https://api.twitter.com/1.1/account/verify_credentials.json",
params: {'include_email': 'true'},
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
}).success(function (result)
{
console.log(result);
alert('USER TIMELINE: ' + JSON.stringify(result));
deferred.resolve(result);
}).error(function (error)
{
alert("Error: " + JSON.stringify(error));
deferred.reject(false);
});
return deferred.promise;
},
storeUserToken: storeUserToken,
getStoredToken: getStoredToken
};
});
From the above code use getTwitterProfileManual this function to get email address in twitter user object response.
Note : To get email address your twitter app must be whitelisted to have access to user email address.
