Created Issue: How to get Access token after redirect to Default.aspx page [22156]

debpyne — Fri, 03 Feb 2012 14:32:12 GMT

after successfully Login to facebook its redirect to redirect_uri, which is Default.aspx.
It redirects successfully but I cant get the access token.

It returns like this Url:
http://localhost:51732/Default.aspx#access_token=AAAE8N2MBAnIBAGlfaQfzPZBqgtveZCRWPvNgZBLhKsxSYgBN5mSzzJnOCL3g5Jl3vyYHyz5juo1fJGLwDDMZB6ZBPkglxbmPGGkhnPSfsZASaGyZADBkYFA&expires_in=5536

Here "access_token" sends with "#" I can't access it in query string.

Can anyone suggest how will I get the access_token?

giangchau92 — Sat, 28 Jan 2012 09:58:58 GMT

I tried following this tutorial but I can't find the property called Secret in the facebook secret (facebookService1.Secret)
I use the facebook SDK V3.0 from page http://facebooktoolkit.codeplex.com/
but it seems to work by only using the ApplicationKey :)
Is this video for an older version of the SDK?

New Post: Sending Facebook message with latest toolkit

alpa — Wed, 31 Aug 2011 15:24:19 GMT

I've been lurking around everywhere to find a good tutorial on sending facebook message but with no avail. Can anyone point me to the right direction to head my search? Some forum posts says that its possible using REST API and others are saying that FB is not allowing messaging anymore to prevent spamming. Also, a note on FB says that REST is about to deprecate. Any help would be greatly appreciated.
Thanks in advance !

Commented Issue: "Incorrect Signature" error when using Stream.Publish() [15391]

dketan — Wed, 24 Aug 2011 15:00:16 GMT

I'm having a very hard time getting Stream.Publish() to work. I keep getting the "incorrect signature" error. This is a Desktop app, not Iframe or FBML. Here's the code I'm using (borrowed from someone else's example of how to make this work):

/////////////////////////////////////
attachment attachment = new attachment();

attachment.caption = "www.icanhascheezburger.com";
attachment.name = "I am bursting with joy";
attachment.href = "http://icanhascheezburger.com/2009/04/22/funny-pictures-bursting-with-joy/";
attachment.description = "a funny looking cat";
attachment.media = new List<attachment_media>(){new attachment_media_image()
{
src = "http://icanhascheezburger.files.wordpress.com/2009/03/funny-pictures-your-cat-is-bursting-with-joy1.jpg",
href = "http://icanhascheezburger.com/2009/04/22/funny-pictures-bursting-with-joy/"
}};
string targetID = "100000xxxxxxxxx"; // the FB user who should receive the message
FBSession.FacebookAPI.Stream.Publish("This is a test message", attachment, null, targetID, Convert.ToInt64(FBSession.Uid));
//////////////////////////////////////////////////////

Stack trace is as follows:

Any help greatly appreciated.

New Post: missing files?

alex_brambila — Fri, 12 Aug 2011 22:00:53 GMT

Just downloaded version 3.01 of the Facebook Developer Toolkit and I'm working through this article http://www.devtacular.com/articles/bkonrad/how-to-retrieve-user-data-from-facebook-connect-in-aspnet/ however, I seem to be missing a file. I'm getting the compiler error: Type or namespace API cannot be found..

on this line:

                API api = new API();

                api.ApplicationKey = connectFB.ApiKey;
                api.SessionKey = connectFB.SessionKey;
                api.Secret = connectFB.SecretKey;
                api.uid = connectFB.UserID;

I've got refs to facebook.dll, and facebook.web.dll as well as using statements to those.

Any ideas??

Commented Issue: error-"The user hasn't authorized the application to perform this action" while posting on page [19509]

nouka — Sun, 29 May 2011 19:39:46 GMT

Hi All,

Using facebooktoolkit i am able to post on the user's wall. But i am not able to post on the page which is administered by that user.

My code is as below-
Facebook.Session.ConnectSession connectsession = new Facebook.Session.ConnectSession(APIKey, AppSecret);
Facebook.Rest.Api api = new Facebook.Rest.Api(connectsession);

api.Session.SessionKey = Auth_token;
api.Session.UserId = UserId;

Facebook.Rest.attachment_media_image myimage = new Facebook.Rest.attachment_media_image();
//href is the link for the image if you click on it
myimage.href = "http://testpage.com";
myimage.src = "http://testpage.com/image.png";
List<Facebook.Rest.attachment_media> mymedia = new List<Facebook.Rest.attachment_media>();
mymedia.Add(myimage);

Facebook.Rest.attachment myattachment = new Facebook.Rest.attachment();

//name is bold heading for entry, to right of image
myattachment.name = "Title of your post by testpage.com";
//href is the link target for the 'name'
myattachment.href = "http://testpage.com";

//caption is the long article text below the name
myattachment.caption = "Here is the main message for the wall/stream post";

//description appears under image
myattachment.description = "Something to describe the image";

myattachment.media = mymedia;

IList<Facebook.Schema.action_link> myactionlinks = new List<Facebook.Schema.action_link>();
Facebook.Schema.action_link myactionlink = new Facebook.Schema.action_link();
myactionlink.href = "http://testpage.com";
myactionlink.text = "Description for hyperlink";
myactionlinks.Add(myactionlink);

//my page
api.Stream.Publish("", myattachment, myactionlinks, "", UserId); //throws error

I have generated the access token for user(with manage_pages,offline_access,publish_stream extended permissions) and based on that access token, i am making the accounts connection (https://graph.facebook.com/me/accounts?access_token=<user_access_token>) to get the access token for the user administered page on facebook. this call successfully returns me the access token for that page.
Now i am using the same code and the access token returned from accounts connection to post the message on that page's wall.
But api.stream.publish call throws error - "The user hasn't authorized the application to perform this action"
I need to get this error resolved as soon as possible for my client, So can anyone please help me out?

Thanks
Alpesh
