提问by Vinay
I am getting user info but unable to get friend list.
<script>
function sortMethod(a, b) {
var x = a.name.toLowerCase();
var y = b.name.toLowerCase();
return ((x < y) ? -1 : ((x > y) ? 1 : 0));
}
window.fbAsyncInit = function() {
FB.init({ appId: 'xxxxxxxxx',
status: true,
cookie: true,
xfbml: true,
oauth: true
});
function updateButton(response) {
var button = document.getElementById('fb-auth');
if (response.authResponse) { // in case if we are logged in
var userInfo = document.getElementById('user-info');
FB.api('/me', function(response) {
userInfo.innerHTML = '<img src="https://graph.facebook.com/' + response.id + '/picture">' + response.name;
button.innerHTML = 'Logout';
});
// get friends
FB.api('/me/invitable_friends', function(response) {
var result_holder = document.getElementById('result_friends');
var friend_data = response.data.sort(sortMethod);
var results = '';
for (var i = 0; i < friend_data.length; i++) {
results += '<div><img src="https://graph.facebook.com/' + friend_data[i].id + '/picture">' + friend_data[i].name + '</div>';
}
// and display them at our holder element
result_holder.innerHTML = '<h2>Result list of your friends:</h2>' + results;
});
button.onclick = function() {
FB.logout(function(response) {
window.location.reload();

};
} else { // otherwise - dispay login button
button.onclick = function() {
FB.login(function(response) {
if (response.authResponse) {
window.location.reload();
}
}, {scope:'email'});
}
}
}
// run once with current status and whenever the status changes
FB.getLoginStatus(updateButton);
FB.Event.subscribe('auth.statusChange', updateButton);
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';

You need to ask for user_friendsin the authorization process:
您需要user_friends在授权过程中要求：
FB.login(function(response) {
if (response.authResponse) {
window.location.reload();
}
}, {scope:'email,user_friends'});
You need this both for /me/friendsand for /me/invitable_friends, see Facebook docs: https://developers.facebook.com/docs/games/invitable-friends/v2.1
你需要这个 for/me/friends和 for /me/invitable_friends，请参阅 Facebook 文档：https: //developers.facebook.com/docs/games/invitable-friends/v2.1
Although you will only get friends who are using the App too with /me/friends. See changelog for more information: https://developers.facebook.com/docs/apps/changelog
虽然你只会得到使用该应用程序的朋友/me/friends。有关更多信息，请参阅变更日志：https: //developers.facebook.com/docs/apps/changelog
What CBroe commented in your question is very important too. invitable_friendsis for Games on facebook.com only.
CBroe 在您的问题中评论的内容也非常重要。invitable_friends仅适用于 facebook.com 上的游戏。

If your app is public and live also some of the friends who are using the app then you can get the list of them.
如果您的应用程序是公开的并且也有一些使用该应用程序的朋友，那么您可以获得他们的列表。
See what the documentation state #reference-user_friends:
查看文档说明#reference-user_friends：
user_friends- Provides access to a person's list of friends that also use your app.
user_friends-提供对也使用您的应用程序的人的朋友列表的访问。
After that you will be able to see what you want.
之后，您将能够看到您想要的内容。
FB.api('/me/friends', function(response){
console.log(response);
}, {scope: 'user_friends'});
