Overview

This article demonstrates LinkedIn social Network Applications.

LinkedIn Application

Application developer has to register application in LinkedIn developer site. Since Tizen Web Application is a Mobile Application, user has to provide some dummy redirect url to receive access token required for authentication. After successful registration, developer will receive api key and security key.

Authorization:

oAuth is a authentication protocol allows application to access user data. Today most of the web application using oauth protocol for developing social network apps. More information on LinkedIn Application authorization is found at authorization article. Below code is used to receive access token, which in turn used to get auth token. While requesting for access token, application has to pass api key, secret key and scope. More information on scope is found in the link

function LinkedIn()
{
	ar token = localStorage['LinkedIn_access_token'] ;
	if( token == null )
	{
		window.authWin = window.open("https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=jpud61ec2pbz&scope=r_fullprofile%20r_network%20w_messages%20rw_groups%20r_contactinfo%20rw_nus&state=DCEEFWF45453sdffef424&redirect_uri=http://localhost/linkedIn");
		onitorLinkedInURL() ;
	}
	else
	{
		$.mobile.changePage('#linkedMainPage');
	}
}

After receiving access token, developer has to request for access token which is used for all requests.

function monitorLinkedInURL() {
  window.int = self.setInterval(function () {
  window.authCount = window.authCount + 1;
  if (window.authWin && window.authWin.location) {
	var currentURL = window.authWin.location.href;
	var inCallback = currentURL.indexOf("http://localhost/linkedIn?code");
	url_code = currentURL 
	if (inCallback >= 0) {
		window.clearInterval(int)               
		window.authWin.close();
		handleLinkedInCode();                 
	}
  }
  if (window.authCount > 60) {
	window.authCount  =0;
	window.clearInterval(int)
	window.authWin.close();
  }
}, 50);

}

		success : function(data) {
			console.log("received job data from server");
			var d = '<ul data-role="listview">' ;
			for(var i =0 ; i < data.values.length; i++){
				if( data.values[i].updateType == "JGRP")
				{
