Currently when my app posts on a users behalf the custom action shows up in the activity log and not on the user's wall. I am expecting the action to show up in /me/feed in the open graph. I am using the c# library. Below is the code I am using:
public async Task JoinSmaxNation(int nationId)
{
dynamic parameters = new ExpandoObject();
parameters.smax_nation = String.Format(_smaxNationUrlFormat, nationId, UserId);
parameters.no_feed_story = false;
parameters.expires_in = 86400;
dynamic result = await _fb.PostTaskAsync("me/smaxsport:join", parameters);
}
It looks like the fb:explicitly_shared=true option was required.

what i am trying to achieve should be simple by theory but hell by implementation, if you think otherwise please help.
so what i am trying to achieve here is that I have my facebook page which I created a developer acount for it, and what i want is to take albums from the page to my website.
I am using the latest stable facebook sdk for .net 6.8.0, and i am assuming that the graph api is on v2.2.
this is the code i am using below to get the access token and access my albums
try
{
var fb = new FacebookClient();
dynamic result = fb.Get("oauth/access_token", new
{
client_id = "---my application number---",
client_secret = "---my application secret---",
grant_type = "client_credentials"
});
var fb2 = new FacebookClient(result.access_token);
dynamic albums = fb2.Get("my application number/albums");
foreach (dynamic albumInfo in albums)
{
try
{
dynamic albumsPhotos = fb2.GetTaskAsync(albumInfo.id + "/photos");
}
catch (Exception Exception)
{
throw Exception;
}
}
}
catch (Exception e)
{
throw e;
}
The data returned in the dynamic albums variables is empty, the thing that confused me more is when i use facebook graph api explorer the call work fine and it return the albums. so what exactly i am missing.
I also read in some threads that you can access your albums without the secret password if they are public but that didn't work for me either i tried it in javascript but no joy.
Thank you in advance.
Since this is your page, it should be pretty easy to retrieve your own photos using Windows PowerShell and http://facebookpsmodule.codeplex.com Get-FBAlbums.
i want to get the facebook friend's list from my application, but returns me data: []... empty! :(
the scenario it's this:
C#
const string QueryToGetFbInfo = "me";
const string QueryToGetFbPhoto = "me?fields=picture.width(200).height(200)";
const string QueryToGetFriendList = "me/friends?fields=name,picture.width(100).height(100)";
private void btnFacebook_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
FacebookSessionClient fbSession = new FacebookSessionClient("FB_APP_ID");
fbSession.LoginWithApp("public_profile, user_friends, read_friendlists, email", "custom_state_string");
}
private async void tbnShowfriends_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
FacebookSession session = SessionStorage.Load();
FacebookClient client = new FacebookClient(session.AccessToken);
// Get Facebook FriendList
dynamic friends = await client.GetTaskAsync(QueryToGetFriendList);
//Get Facebook user info
dynamic result = await client.GetTaskAsync(QueryToGetFbInfo);
GraphUser user = new GraphUser(result);
//Get profile picture from facebook
dynamic result1 = await client.GetTaskAsync(QueryToGetFbPhoto);
JsonObject json = result1.picture.data;
var picture = (IDictionary<string, object>)json;
....
}
Facebook App Config has the permissions... forgot some ?.. the new panel confuses me a little, Maybe I forgot something in the application settings...
when i select Api Graph, returns me, a friendlist, fine!
but when I select my application, I do not return anything
What I forgot ?... how can i fix this problem ?
You authed Graph Explorer using API v1.0 which means that that app will get all your friends until 4/30/2014. You app you authed using v2.0 or v2.1 which means that you will only get friends that are also using the app
I have registered an app in facebook developers program and I can retrieve posts from facebook page using fb api, but I cannot retrieve posts from facebook profile. Should I use some different access token for both page or profile? Is there a different way for retrieving posts from facebook page and profile?
Any help will be appreciated!
You may need the user_status permission.
And you call the posts using this graph query {USER_ID}?fields=statuses
Prerequisite:- You need to have valida FB token for all the request:-
I am answering using c# language.
Step 1:- First you need to get the user's FB id using FB token
I am using Facebook SDK 7.0.6 for querying purpose
here's how to initialize the FB service which we will use in our consecutive calls.
FacebookService facebookService = new FacebookService(facebookToken);
var _facebookClient = new Facebook.FacebookClient(token);
Code snippet
public string GetFacebookID(string facebookToken)
{
dynamic result = _facebookClient.Get("me?fields=id");
if (result.ToString().Contains("id"))
{
return result["id"];
}
return string.Empty;
}
after that you can execute below method to get user's post using FB ID and token
public List<Post> GetPostsForUser(string facebookID)
{
List<Post> posts = new List<Post>();
dynamic result = _facebookClient.Get(facebookID + "/posts"); //Case Sensitive, Posts doesn´t work
if (result.ToString().Contains("data") && result.data.Count > 0)
{
foreach (var item in result.data)
{
posts.Add(new Post
{
ID = item.id,
Story = item.story,
Message = item.message,
Created_Time = Convert.ToDateTime(item.created_time),
Reactions = GetReactions(item.id)
});
}
result = _facebookClient.Get(GetNextURL(result.ToString()));
}
return posts;
}
So I tried to post on my friends wall using the following code:
var fb = new FacebookClient(_accessToken);
dynamic parameters = new ExpandoObject();
parameters.message = "Google is your friend";
parameters.link = "http://gidf.de/";
parameters.Name = "Test";
parameters.from = new { id = "100000", name = "me" };
parameters.to = new { id = "1000001", name = "friend" };
dynamic result = fb.Post("1000001/feed", parameters);
However, I get told that my application does not support this. I did some googling work, and read that [USER_ID]/feed is deprecated and that I have to invoke the feed dialog to ask the user to publish it. How would I go on doing this with the C# SDK?
As of February 6, 2013, you can't post to Friends Timeline on behalf of the user.
Read Here: https://developers.facebook.com/roadmap/completed-changes/
Client-Side you can use the FB.ui method to pop up the feed dialog.
Here's an example: https://stackoverflow.com/a/15426243/1405120
Server-Side, you can use the URL Redirection.
https://www.facebook.com/dialog/feed?

I'm absolutely new to programming and just managed to learn the basics of ActionScript 3. Now, I would like to learn how to post on my Friends' Walls via the as3 SDK using the UI class (taken from a nice Tutorial):
This is how I post on my own Wall:
protected function newsFeed ():void
{
// define your caption text
var theCaption:String = "CaptionText";
// define the descrition text
var theDescription:String = "Text for game Achievement";
// We need to follow the FB docs to tell it what sort of input we are sending to FB
// We are trying to set the 'feed'
var methodInput:String = 'feed';
var thePicture:String = "mylink/picture.png";
var theLink:String = "mylink";
var theName:String = "Name of FB Status Setter";
// Create an object that we'll call 'data' and fill it with the actual data we're sending to Facebook
var data:Object = {
caption:theCaption,
description:theDescription,
picture:thePicture,
name:theName,
link:theLink
};
Facebook.ui(methodInput, data, onUICallback);
}
protected function onUICallback(result:Object):void
{
// do something
}
This works perfectly fine. I know that I have to integrate the parameter "to" somewhere. But I don't know where and how. Sorry I'm very very new to this. This is from Facebook Docs
Properties
from: The ID or username of the user posting the message. If this is unspecified, it defaults to the current user. If specified, it must be the ID of the user or of a page >that the user administers.
to: The ID or username of the profile that this story will be published to. If this >is unspecified, it defaults to the the value of from.
Hopefully someone can help me out.
Best Regards,
Amir
P.S.: Is there a way to post only one friend's wall and another way to post on several friends' walls?
I believe you want to use Facebook.api() rather than 'ui'. According to the documentation for the AS3 FB API, 'ui' just opens the share dialog. If you want to create a post on a friends wall, then you'll want to use 'api'.
I haven't tested this in Flash, but I think you can set the method as /PROFILE_ID/feed ... of course replacing "PROFILE_ID" with the FB uid of the friend. Then, include the arguments; message, picture, link, name, caption, description and source in your data object.
So your code would look something like:
var method:String = "/friend_id/feed";
var data:Object = {};
data.message = "Your message";
data.picture = "http://www.google.com/kittens.jpg";
data.link = "http://www.mysite.com/link";
data.caption = "Your caption";
data.description = "Your description";
data.source = "http://www.mysite.com/video.swf";//(optional) source is a video or Flash SWF
Facebook.api(method, yourCallback, data, "POST");
function yourCallback(result:Object, fail:Object):void {
if (result) {
trace(result)
} else if (fail) {
trace(fail);
}
}
If you have multiple friends, you could probably just put the uid's in an array and loop through the method above. The AS3 API has a batch request method that I haven't tried, but you can check out the Documentation.
Facebook has some pretty helpful tools that are somewhat hidden.
Checkout their Debugger and their Graph API Explorer
Hope that's helpful.
