I'm developing a desktop application and I want to subscrbe to Facebook Realtime API.
This is my code on the client (WPF app):
After my code is executed, at fb.Post I get the following error: (OAuthException) (#15) This method is not supported for native apps.
I also tried the code from ASP.NET and got the same error, so I don't this the message is very intuitive.
How can I solve this problem and succesfully subscribe to Facebook Realtime API?
var tokenUrl = "https://graph.facebook.com/oauth/access_token?client_id=" + Constants.Facebook.AppId + "&client_secret=" + Constants.Facebook.AppSecret + "&grant_type=client_credentials";
var requestToken = WebRequest.Create(tokenUrl);
HttpWebResponse res = (HttpWebResponse)requestToken.GetResponse();
Stream resst = res.GetResponseStream();
var sr = new StreamReader(resst);
string responseToken = sr.ReadToEnd();
var app_access_token = responseToken.Replace("access_token=", "");
var callback_url = "[MY CALLBACK URL]";
var fb = new FacebookClient(app_access_token);
var parameters = new Dictionary<string, string>();
parameters.Add("object", "user");
parameters.Add("fields", "feed");
parameters.Add("callback_url", callback_url);
parameters.Add("verify_token", "abc");
parameters.Add("access_token", app_access_token);
var uri = string.Format("https://graph.facebook.com/{0}/subscriptions?", Constants.Facebook.AppId);
var response = fb.Post(uri, parameters);
Your application configured as "Native Application" in developer app (advanced settings) and as stated in error this type of apps can't use Real-Time updates (sounds like a good reason to me).
Documentation for Real-Time Updates omit this info, you can file a bug and see what officials say...

I have implemented the custom security on my reporting services 2016 and it displays the login page once the URL for reporting services is typed on browser URL bar (either reports or reportserver)
I am using the following code to pass the Credentials
when i use the code WITHOUT my security extension it works and looks like this
ICredentials _executionCredentials;
CredentialCache myCache = new CredentialCache();
Uri reportServerUri = new Uri(ReportServerUrl);
myCache.Add(new Uri(reportServerUri.GetLeftPart(UriPartial.Authority)),
"NTLM", new NetworkCredential(MyUserName, MyUserPassword));
_executionCredentials = myCache;
when i use the code WITH the security extension it doesnt work and looks like this
ICredentials _executionCredentials;
CredentialCache myCache = new CredentialCache();
Uri reportServerUri = new Uri(ReportServerUrl);
myCache.Add(new Uri(reportServerUri.GetLeftPart(UriPartial.Authority)),
"Basic", new NetworkCredential(MyUserName, MyUserPassword));
_executionCredentials = myCache;
and i get an Exception saying "The response to this POST request did not contain a 'location' header. That is not supported by this client." when i actually use this credentials
Is "basic" the wrong option ?
Have anyone done this ?
Update 1
Well it turns out that my SSRS is expecting an Authorisation cookie
which i am unable to pass (according to fiddler, there is no cookie)
HttpWebRequest request;
request = (HttpWebRequest)HttpWebRequest.Create("http://mylocalcomputerwithRS/Reports_SQL2016/api/v1.0");
CookieContainer cookieJar = new CookieContainer();
request.CookieContainer = cookieJar;
Cookie authCookie = new Cookie("sqlAuthCookie", "username:password");
authCookie.Domain = ".mydomain.mylocalcomputerwithRS";
if (authCookie != null)
request.CookieContainer.Add(authCookie);
request.Timeout = -1;
HttpWebResponse myHttpWebResponse = (HttpWebResponse)request.GetResponse();
That's how I got it (SSRS 2017; api v2.0). I took the value for the "body" from Fiddler:
var handler = new HttpClientHandler();
var httpClient = new HttpClient(handler);
Assert.AreEqual(0, handler.CookieContainer.Count);
// Create a login form
var body = new Dictionary<string, string>()
{
{"__VIEWSTATE", "9cZYKBmLKR3EbLhJvaf1JI7LZ4cc0244Hpcpzt/2MsDy+ccwNaw9hswvzwepb4InPxvrgR0FJ/TpZWbLZGNEIuD/dmmqy0qXNm5/6VMn9eV+SBbdAhSupsEhmbuTTrg7sjtRig==" },
{"__VIEWSTATEGENERATOR", "480DEEB3"},
{ "__EVENTVALIDATION", "IS0IRlkvSTMCa7SfuB/lrh9f5TpFSB2wpqBZGzpoT/aKGsI5zSjooNO9QvxIh+QIvcbPFDOqTD7R0VDOH8CWkX4T4Fs29e6IL92qPik3euu5QpidxJB14t/WSqBywIMEWXy6lfVTsTWAkkMJRX8DX7OwIhSWZAEbWZUyJRSpXZK5k74jl4x85OZJ19hyfE9qwatskQ=="},
{"txtUserName", "User"},
{"txtPassword", "1"},
{"btnLogin","Войти"}
};
var content = new FormUrlEncodedContent(body);
// POST to login form
var response = await httpClient.PostAsync("http://127.0.0.1:777/ReportServer/Logon.aspx", content);
// Check the cookies created by server
Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);
var cookies = handler.CookieContainer.GetCookies(new Uri("http://127.0.0.1:777/ReportServer"));
Assert.AreEqual("sqlAuthCookie", cookies[0].Name);
// Make new request to secured resource
var myresponse = await httpClient.GetAsync("http://127.0.0.1:777/Reports/api/v2.0/Folders");
var stringContent = await myresponse.Content.ReadAsStringAsync();
Console.Write(stringContent);
As an alternative you can customize SSRS Custom Security Sample quite a bit.
I forked Microsoft's Custom Security Sample to do just what you are describing (needed the functionality at a client long ago and reimplemented as a shareable project on GitHub).
https://github.com/sonrai-LLC/ExtRSAuth
I created a YouTube walkthrough as well to show how one can extend and debug SSRS security with this ExtRSAuth SSRS security assembly https://www.youtube.com/watch?v=tnsWChwW7lA
TL; DR; just bypass the Microsoft example auth check in Login.aspx.cs and put your auth in Page_Load() or Page_Init() event of Login.aspx.cs- wherever you want to perform some custom logging check- and then immediately redirect auth'd user to their requested URI.
In my application image has to post to Facebook,mail.Sorry i am new to windows phone.i don't have a idea.please help me.what i can do first.
If you want to share a status you can use your facebook account on your phone using Share link task (with this method you can only post on your wall) http://msdn.microsoft.com/en-us/library/hh394027%28v=vs.92%29.aspx
To post (pictures, messages or others) on every wall you have access you need some things :
First you need to create a facebook application using this link :
Facebook developers
After that you need to identify yourself using a WebBrowser control with the link related to your application. The application requests authorization to perform certain actions such as posting. You need to detail the authorizations like this :
Dictionary<string, string> uriParams = new Dictionary<string, string>() {
{"client_id", "your app id"},
{"response_type", "token"},
{"scope", "user_about_me, offline_access, publish_stream"}, //The rights
{"redirect_uri", "http://www.facebook.com/connect/login_success.html"},
{"display", "touch"}
};
The Dictionary also contains the redirection uri to define if the operation was successful.
Finally you are authentified and receive an access token. Now you can use a WebRequest POST to post a message using this token :
WebRequest request = HttpWebRequest.Create("https://graph.facebook.com/" + the id of your wall + "/feed");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.BeginGetRequestStream((reqResult) =>
{
using (Stream strm = request.EndGetRequestStream(reqResult))
using (StreamWriter writer = new StreamWriter(strm))
{
writer.Write(client.AccessToken);
writer.Write("&message=" + HttpUtility.UrlEncode(status));
}
request.BeginGetResponse((result) =>
{
try
{
var response = request.EndGetResponse(result);
using (var rstrm = response.GetResponseStream())
{
var serializer = new DataContractJsonSerializer(typeof(FacebookPostResponse));
var postResponse = serializer.ReadObject(rstrm) as FacebookPostResponse;
callback(true, null);
}
}
catch (Exception ex)
{
callback(false, ex);
}
}, null);
}, null);
Here is how to post a message on a facebook page,
You should give the Facebook C# SDK a try
Facebook C# SDK
I have built this in once in an app of mine. They have plenty examples available which should be useful.
I am designing an app for iPhone and android in which I have to integrate facebook, twitter, yahoo, gmail, openId. I had integrated facebook and twitter, but how to go for yahoo, gmail and openId? How to login these through app and get the user information?
Please do show me a way to implement this. Any tutorial may help.
Thanks.
To integrate gmail may this url's help you
Google's documentation
Introduction about integrating gmail with iphone
Examples to integrate with iphone
Api's for integrating blogger,google analytics etc
For yahoo you can use this
String YAHOO_RESOURCE_URL = "http://social.yahooapis.com/v1/me/guid/profile?fomat=xml";
String CALLBACK_URL = "oauth://testApp";
String YAHOO_REQUEST_TOKEN_URL = "https://api.login.yahoo.com/oauth/v2/get_request_token";
String YAHOO_ACCESS_TOKEN_URL = "https://api.login.yahoo.com/oauth/v2/get_token";
String YAHOO_AUTHORIZE_URL = "https://api.login.yahoo.com/oauth/v2/request_auth";
// Oauth consumer and provider.
CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(Constants.YAHOO_CONSUMER_KEY, Constants.YAHOO_CONSUMER_SERECT_KEY);
OAuthProvider provider = new CommonsHttpOAuthProvider(YAHOO_REQUEST_TOKEN_URL , YAHOO_ACCESS_TOKEN_URL, YAHOO_AUTHORIZE_URL);
provider.setOAuth10a(true);
// First retrive request token.
String authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
String yahooToken = consumer.getToken();
String yahooTokenSecret = consumer.getTokenSecret();
Open the authUrl in android web browser, this will launch login page, then after login will ask for permissions, accepting the permissions will return in your app using callback url.
Now,
In onResume
Uri uri = this.getIntent().getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
String oauthToken = uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_TOKEN);
String oauthVerifier = uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);
consumer = new CommonsHttpOAuthConsumer(Constants.YAHOO_CONSUMER_KEY, Constants.YAHOO_CONSUMER_SERECT_KEY);
consumer.setTokenWithSecret(yahooToken, yahooTokenSecret);
provider = new CommonsHttpOAuthProvider(YAHOO_REQUEST_TOKEN_URL, YAHOO_ACCESS_TOKEN_URL, YAHOO_AUTHORIZE_URL);
provider.setOAuth10a(true);
// Now retrive access token
provider.retrieveAccessToken(consumer, oauthVerifier);
String token = consumer.getToken();
String tokenSecret = consumer.getTokenSecret();
consumer.setTokenWithSecret(token, tokenSecret);
// Get the GUID from this.
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet("http://social.yahooapis.com/v1/me/guid?format=json");
consumer.sign(request);
HttpResponse response = httpClient.execute(request);
Parse the response to get GUID.
// Now use the GUID to get profile info.
DefaultHttpClient httpClient = new DefaultHttpClient();
String strUrl = "http://social.yahooapis.com/v1/user/"+ strGUID +"/profile?format=json";
HttpGet request = new HttpGet(strUrl);
consumer.sign(request);
HttpResponse response = httpClient.execute(request);
Parse the response and njoy :)
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:
I'm using the .Net HttpWebRequest instead of the Facebook C# SDK to grab the app access_token because (as of version 5.011 RC1) the SDK throws a SerializationException. It seems that the SDK is expecting a JSON response from Facebook, but Facebook returns the access token in the form: access_token=some_value (which is not valid JSON).
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.

return resul["id"].ToString();
}
I am using facebook graph apis with FacebookSdk from codeplex.
I am not able to post the venue with this code due to the open bug in facebook API. Other things work fine. I suggest you implement this venue parameters as well so that the functionality will work as soon as facebook resolves this issue.
Mark this as answer if it works for you.It will also help other people to save time on searching.
