I am trying to update the bookmark count field with the SDK but have not had any success yet.
Can somebody tell me what classes I need to instantiate to do something similar to the following link:
http://developers.facebook.com/blog/post/464
Note:
The link demonstrates how to set the bookmark count and delete it. I would like to be able to do the same with the SDK, any help would be appreciated.
To do this, first you need to get you app's access token:
private string GetAppAccessToken() {
var fbSettings = FacebookWebContext.Current.Settings;
var accessTokenUrl = String.Format("{0}oauth/access_token?client_id={1}&client_secret={2}&grant_type=client_credentials",
"https://graph.facebook.com/", fbSettings.AppId, fbSettings.AppSecret);
// the response is in the form: access_token=foo
var accessTokenKeyValue = HttpHelpers.HttpGetRequest(accessTokenUrl);
return accessTokenKeyValue.Split('=')[1];
}
A couple of things to note about the method above:
HttpHelpers.HttpGetRequest simply uses .Net's HttpWebRequest. You can just as well use WebClient, but whatever you choose, you ultimately want to make this http request:
GET https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials HTTP/1.1 Host: graph.facebook.com
Now that you have a method to retrieve the app access_token, you can generate an app request as follows (here I use the Facebook C# SDK):
public string GenerateAppRequest(string fbUserId) {
var appAccessToken = GetAppAccessToken();
var client = new FacebookClient(appAccessToken);
dynamic parameters = new ExpandoObject();
parameters.message = "Test: Action is required";
parameters.data = "Custom Data Here";
string id = client.Post(String.Format("{0}/apprequests", fbUserId), parameters);
return id;
}
Similarly, you can retrieve all of a user's app requests as follows: Note: you probably don't want to return "dynamic", but I used it here for simplicity.
public dynamic GetAppRequests(string fbUserId) {
var appAccessToken = GetAppAccessToken();
var client = new FacebookClient(appAccessToken);
dynamic result = client.Get(String.Format("{0}/apprequests", fbUserId));
return result;
}
I hope this helps.
