Commented Issue: Disconnects Facebook account after 2 hours. Error occured while retrieving Facebook data (OAuthException) Error validating access token: Session has expired at unix time 1340802000. The current unix time is 1341470471. [5934]

pragneshs9 — Thu, 05 Jul 2012 10:14:58 GMT

Previously i was using facebook v5.2 with below code
var fbWebContext = new FacebookWebContext(FacebookApplication.Current, ControllerContext.HttpContext);
if (fbWebContext.IsAuthorized("user_about_me,publish_stream,email,user_status".Split(',')))
}
var fb = new FacebookWebClient(user.FacebookAccessToken);
dynamic me = fb.Get("me");
string first_name = me.first_name;
string last_name = me.last_name;
-----
Above code was working fine but i have to add the offline_access for long live session it was expire with in 2 hours so i download the facebook v6 version. After updating the version the above code stops working.

FacebookWebContext(IFacebookApplication settings, HttpContextBase httpContext)
I am not getting the IFacebookApplication interface. how can i pass the settings value.
Error:-
Could not load type 'Facebook.FacebookApplication' from assembly 'Facebook, Version=6.0.10.0, Culture=neutral, PublicKeyToken=58cb4f2111d1e6de'.

Please give me the solution as early as possible.

Commented Issue: "ClientID required" exception because FacebookApplication.Current is not set by FacebookWebContext [5902]

For the description of the issue and for a workaround see: http://facebook.stackoverflow.com/questions/7381370/facebook-c-sdk-oauth-exception-clientid-required/7386743

The problem is that when FacebookWebContext is instantiated with app settings then FacebookApplication.Current doesn't properly get set. The other way around: FacebookSession uses FacebookApplication.Current, but IMHO not a kind of global object should be used but the IFacebookApplication instance passed around.

Closed Issue: JsonObject should be marked as serializable [5933]

prabirshrestha — Tue, 06 Mar 2012 15:02:51 GMT

Why? we're using Load balancing on our servers and when active we
get the error: Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted & [SerializationException: Type 'Facebook.JsonObject' in Assembly 'Facebook, Version=5.4.1.0, Culture=neutral, PublicKeyToken=58cb4f2111d1e6de' is not marked as serializable.]

Hi Prabir, I'm opening the issue per your request in this discussion:
http://facebooksdk.codeplex.com/discussions/284103

It seems like every time I try to login I get a KeyNotFoundException. It's rendering the application unusable since there's no graceful way out of this exception, at least none that I know. Thank you for your quick response!

I think the indexer in that Json object implementation is failing. It's really rendering the whole application useless. I think the problem is here, but I'm not 100% certain:

private object BuildExchangeCodeForAccessTokenResult(string json)
{
var returnParameter = new JsonObject();
FacebookUtils.ParseQueryParametersToDictionary("?" + json, returnParameter);

// access_token=string&expires=long or access_token=string
// Convert to JsonObject to support dynamic and be consistent with the rest of the library.
var jsonObject = new JsonObject();
jsonObject["access_token"] = returnParameter["access_token"]; <<<<<<<<Here
....

//Since his/her indexer implementation for JsonObject in JsonSimple.CS, no check for "ContainsKey":
public object this[string key]
{
get { return _members[key]; }
set { _members[key] = value; }
}

seems like it needs the following line of code

var jsonObject = new JsonObject();

if(jsonObject.ContainsKey("access_token"))
jsonObject["access_token"] = returnParameter["access_token"];

could you either file a new issue or send a pull request.

Commented Issue: POST to graph + Json Encoding doesn't do what it "should" [5915]

prabirshrestha — Sun, 12 Feb 2012 03:05:32 GMT

I'm using the ads api through graph. Just transferred over. We build up an elaborate set of ExpandoObjects to post the ad. One of the sub-ExpandoObjects is called "creative" and it has the creative. The JSON encoding that's happening in here seems to be brain damaged about escaping double quotes. Here's a part of the posted form grabbed from the stream. Note the "body" text has double quotes in it and whatever JSON encoding is happening inside the FacebookSDK seems to be falling down here:

Content-Disposition: form-data; name="creative"

{"title":"Put your quarters up!","body":"Please "check" out the classics at the coinop.org museum.","image_file":"@image_7036.png","type":27,"story_id":"266129693418752_286263474731831","object_id":266129693418752,"name":"Dynamic 1_polybius.aspx_Arcade Games"}
--8ce614f4e9a4932

this is the function we have to do the post:

public static dynamic GraphPost(string url, IDictionary<string, object> postData)
{
var app = new Facebook.FacebookClient();
dynamic result = app.Post(url, postData);
return result;
}

the url is:

https://graph.facebook.com/act___________/adgroups?access_token=______

So it has the proper token, etc.

Any ideas on why that's happening? I don't want to write checks for double quote handling if this is a bug in the FacebookSDK, which at the moment I think is true.

thanks

Commented Issue: FacebookWebContext.HasPermission fails [5922]

prabirshrestha — Mon, 06 Feb 2012 22:31:00 GMT

FacebookWebContext.HasPermission fails in some cases because FacebookWebContext.HasPermissions doesn't take its "permissions" parameter into account.

For example, FacebookWebContext.Current.HasPermission("email") fails because it uses FacebookWebContext.Current.HasPermissions(..., ["email"]), which returns ["installed", "email", "status_update", ...] instead of just ["email"].

Closed Feature: Add ability to configure the LoginUrl globally [5873]

ntotten — Mon, 06 Feb 2012 20:36:50 GMT

The LoginUrl on the FacebookAuthorizeAttribute is today a instance property and it doesn't support a global property. This means the login URL has to be replicated whereever the attribute is used. Please add support for a web.config property or use the existing loginUrl within ASP.NET auth configuration.
Comments: Fixed in 5.0.46.

Closed Task: FacebookOAuthResult(IDictionary parameters) ignores the error query string parameter [5918]

ntotten — Mon, 06 Feb 2012 20:36:28 GMT

Looking at the constructor, it seems that the "error" query string parameter is not being stored. Facebook isn't documenting the error_reason parameter (see http://developers.facebook.com/docs/oauth/errors/) which makes is difficult to handle authorization errors. Is it possible to add this to the class as the Error property?

Comments: Fixed in 5.4.1

Closed Issue: White page on WP7 [5919]

ntotten — Mon, 06 Feb 2012 20:35:22 GMT

If i turn on the Device Security on FB i get white screen after entering code from SMS instead of page with token.
This is the uri i get
http://www.facebook.com/dialog/permissions.request?_path=permissions.request&app_id=137409049650615&redirect_uri=http://www.facebook.com/connect/login_success.html&display=touch&response_type=token&fbconnect=1&perms=offline_access&from_login=1&refsrc=http://m.facebook.com/checkpoint/&refid=0&m_sess=RHKNu-v7bCAf2M&_rdr

If i open it in my Firefox on PC it redirects to page with AcessToken, but on device nothing happens.

Maybe u have any ideas?
