How to get Facebook friends' email?
In my application i have to retrieve user's friends email address.I tried the following code,But i didn't get the friends email address.
My code:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'xxxxxxxxxxxxxxx',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
oauth :true
});
function login(){
/* Show User's Name*/
FB.api('/me/friends', function(response) {
alert("user name:"+response.name);
alert("user mailid:"+response.email);
// document.getElementById('login').style.display = "block";
// document.getElementById('login').innerHTML = response.name + " succsessfully logged in!";
});
//window.location="http://google.com"; // Redirect to Another Page.
}
But in the alert is not showing the mail id.I googled for this ,i found that email is not public property ,so what i can i do for retrieving the mail id.

Answer 2

First Initialize FB Javascript SDK as following.
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
// init the FB JS SDK
FB.init({
appId : 'YOUR_APP_ID', // App ID from the App Dashboard
channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File for x-domain communication
status : true, // check the login status upon init?
cookie : true, // set sessions cookies to allow your server to access the session?
xfbml : true // parse XFBML tags on this page?
});
// Additional initialization code such as adding Event Listeners goes here
};
// Load the SDK's source Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
The above code will initialize your FB SDK. Now in JavaScript write following function.
Refer this document for more details.
function initiateFB Login()
{
FB.login(function(response) {
if (response.authResponse)
{
//Login Success if you want you can initiate request for friend list here only.
FB.api('/me/friends/fields=id,username', function(resp)
{
/// Process the resp over here. This resp will be JSON response of friend request
}
);
}
else
{
console.log('User cancelled login or did not fully authorize.');
}
});
}
You can get the username i.e. FB User Name. Below is the request for that.
me/friends?fields=id,username
This request will give you a JSON response of following format.
{
"data": [
{
"id": "FB_ID",
"username": "FB_USER_NAME"
},
{
"id": "FB_ID",
"username": "FB_USER_NAME"
}
]
}
You can parse this and get the username.
Hope this helps.
