Accessing facebook for posts etc with Graph API c# unity3d

Question

I\'m using C# in MonoDevelop with the Graph API to interact with users facebook pages.

I\'ve become thoroughly confused though.

Are these the correct steps?<

Answer 1

Use the C# Facebook library. There is a sample project called facebook-aspnet-sample which shows you authentication and login. Also, have a look at this tutorial page which deals with how to connect from a Unity3d game to Facebook. The tut is short but the demo project download is useful.

There are also plugins for sale that enable Facebook access from Unity3d.

Answer 2

after your have your FB app ready, indeed, you need to get a token. However, token is always requested in the context of a USER - and therefore user should authenticated on the website. That means that Facebook login dialog should be displayed - which will ask user if he indeed trusts the application. There are different ways to do this - here is the generic page about FB authentication: https://developers.facebook.com/docs/authentication/, and this one explains how to do this in Android: https://developers.facebook.com/docs/mobile/android/sso/

if you want to go with JavaScript authentication (which I personally use in MVC3 project), here is a little bit modified example from https://developers.facebook.com/docs/authentication/client-side/ which does this. Remember to change app id and permissions to the ones you need.

<div id="fb-root"></div>
<script>
    // Load the SDK 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));

    // Init the SDK upon load
    window.fbAsyncInit = function () {
        FB.init({
            appId: '@EventController.FB_APP_ID', // App ID
            channelUrl: '//' + window.location.hostname + '/channel.htm', // Path to your Channel File
            status: false, // check login status
            cookie: false, // enable cookies to allow the server to access the session
            xfbml: false  // parse XFBML
        });

        // listen for and handle auth.statusChange events
        FB.Event.subscribe('auth.statusChange', function (response) {
            if (response.authResponse) {
                // user has auth'd your app and is logged into Facebook
                FB.api('/me', function (me) {
                    // get info about the user, for example
                })
                //document.getElementById('auth-loggedout').style.display = 'none';
            } else {
                // user has not auth'd your app, or is not logged into Facebook
                //document.getElementById('auth-loggedout').style.display = 'block';
            }
        });

        // respond to clicks on the login and logout links
        document.getElementById('auth-loginlink').addEventListener('click', function () {
            FB.login(function (response) {
                // handle the response
                if (response.authResponse != null) {
                    // HERE IS THE TOKEN YOU CAN USE
                    var token = response.authResponse.accessToken;
                } else {

                }
                // AND THESE ARE THE PERMISSIONS YOU WANT YOUR APP TO REQUEST
            }, { scope: 'manage_pages,publish_stream' });
        });
    };
</script>

One catch here - your FB app should have your website URL (even if it is http://localhost/) in App -> Settings -> Website URL field. Also you should put channel.htm file into the root of your website with one line of code in it:

<script src="//connect.facebook.net/en_US/all.js">
