Twitter OAuth Ionic 2 - authentication

Question

Its possible generate a Twitter token and secret token in Nodejs and after use it to open the browser for authenticate with "https://api.twitter.com/oauth/authenticate"?
I use this way to get the token:
app.get('/auth/twitter/token', function (req, res) {
var requestTokenUrl = 'https://api.twitter.com/oauth/request_token';
var requestTokenOauth = {
consumer_key: "2z8MTR8KAZuFafPHsEQ0ZBgo1",
consumer_secret: "ksPiaQz7ihCrOh3m4iRCsXZzQuSkkmcv4CLGiJQwREWeaQl7St"
};
request.post({
url: requestTokenUrl,
oauth: requestTokenOauth
}, function (err, response, body) {
var oauthToken = qs.parse(body);
res.send(oauthToken);
});
});
When I get this token in the client "https://api.twitter.com/oauth/authenticate?oauth_token=TOKEN" I got this problem: "This page is no longer valid. It's looks like someone already used the token information your provider, blabla.."
The problem is due to the way that I get the Token?
I'm using ng2-cordova-auth but this lib dont have twitter auth, I'm just trying to implement
This is my implementation:
"use strict";
var utility_1 = require("../utility");
var PROVIDER_NAME = "Twitter";
var Twitter = (function () {
function Twitter(options) {
this.twitterOptions = options;
this.flowUrl = ""
}
Twitter.prototype.login = function (token, tokenSecret) {
var _this = this;
return new Promise(function (resolve, reject) {
_ this.flowUrl = "https://api.twitter.com/oauth/authenticate?oauth_token="+token;
var browserRef = window.cordova.InAppBrowser.open(_this.flowUrl);
browserRef.addEventListener("loadstart", function (event) {
if ((event.url).indexOf(_this.twitterOptions.redirectUri) === 0) {
browserRef.removeEventListener("exit", function (event) { });
browserRef.close();
var parsedResponse = event.url.split("?")[1].split("&");
if (parsedResponse) {
resolve(parsedResponse);
}
else {
reject("Problem authenticating with " + PROVIDER_NAME);
}
}
});
browserRef.addEventListener("exit", function (event) {
reject("The " + PROVIDER_NAME + " sign in flow was canceled");
});
});
};
return Twitter;
}());
exports.Twitter = Twitter;
In my component/controller I make this:
//With twitterToken I get the token from NodeJs
this.API.twitterToken().subscribe(
data => {
this.twitterOAuth.login(data.oauth_token, data.oauth_token_secret).then((success) => {
alert(JSON.stringify(success))
}, (error) => {
alert(JSON.stringify(error));
});
},
err => alert(JSON.stringify(err))
);

Have you tried the Twitter Connect plugin? Does this help?
Plugin to use Twitter Single Sign On Uses Twitter's Fabric SDK
An example of use is
import {TwitterConnect} from 'ionic-native';
function onSuccess(response) {
console.log(response);
// Will console log something like:
// {
// userName: 'myuser',
// userId: '12358102',
// secret: 'tokenSecret'
// token: 'accessTokenHere'
// }
}
TwitterConnect.login().then(onSuccess, onError);
