Am trying to build an application using facebook sdk in silverlight.
In my application I need to send "like" for a post, to achieve this am using the following Async call:
_fb.Stream.AddLikeAsync(_dataAccess.Session.UserId, feed.stream_post.post_id, OnLikeCompleted, null);
which is giving an exception saying
{Facebook.Utility.FacebookException: A session key must be specified
when request is signed with a session secret
at Facebook.Utility.Utilities.ParseException(String response, Boolean JSONFormat)
at Facebook.Rest.RestBase.OnRequestCompleted(Object sender, RequestCompletedEventArgs e)}
private void lnkLike_Click(object sender, RoutedEventArgs e)
{
var feed = (sender as FrameworkElement).DataContext as StreamStory;
MessageBox.Show(feed.stream_post.post_id.ToString());
_fb.Stream.AddLikeAsync(_dataAccess.Session.UserId, feed.stream_post.post_id, OnLikeCompleted, null);
}
private void OnLikeCompleted(bool result, Object state, FacebookException e)
{
if (e == null)
{
Dispatcher.BeginInvoke(() => MessageBox.Show("likes success"));
var actual = result;
}
else
{
Dispatcher.BeginInvoke(() =>MessageBox.Show("Error: " +e.Message));
}
}
Please help me resolve the above issue. Thanks in advance.
You are using code from the Facebook Developer Toolkit that is nearly 3 years old. Facebook has changed their API many times since then. You need to reference Facebook's developer documents and consider using the Facebook C# SDK which is compatible with Facebook's current API.

I'm having no luck getting a response from v4 of the Google Sheets API when running against a public (i.e. "Published To The Web" AND shared with "Anyone On The Web") spreadsheet.
The relevant documentation states:
"If the request doesn't require authorization (such as a request for public data), then the application must provide either the API key or an OAuth 2.0 token, or both—whatever option is most convenient for you."
And to provide the API key, the documentation states:
"After you have an API key, your application can append the query parameter key=yourAPIKey to all request URLs."
So, I should be able to get a response listing the sheets in a public spreadsheet at the following URL:
https://sheets.googleapis.com/v4/spreadsheets/{spreadsheetId}?key={myAPIkey}
(with, obviously, the id and key supplied in the path and query string respectively)
However, when I do this, I get an HTTP 401 response:
{
error: {
code: 401,
message: "The request does not have valid authentication credentials.",
status: "UNAUTHENTICATED"
}
}
Can anyone else get this to work against a public workbook? If not, can anyone monitoring this thread from the Google side either comment or provide a working sample?
I managed to get this working. Even I was frustrated at first. And, this is not a bug. Here's how I did it:
First, enable these in your GDC to get rid of authentication errors.
-Google Apps Script Execution API
-Google Sheets API
Note: Make sure the Google account you used in GDC must be the same account you're using in Spreadsheet project else you might get a "The API Key and the authentication credential are from different projects" error message.
Go to https://developers.google.com/oauthplayground where you will acquire authorization tokens.
On Step 1, choose Google Sheets API v4 and choose https://www.googleapis.com/auth/spreadsheets scope so you have bot read and write permissions.
Click the Authorize APIs button. Allow the authentication and you'll proceed to Step 2.
On Step 2, click Exchange authorization code for tokens button. After that, proceed to Step 3.
On Step 3, time to paste your URL request. Since default server method is GET proceed and click Send the request button.
Note: Make sure your URL requests are the ones indicated in the Spreadsheetv4 docs.
Here's my sample URL request:
https://sheets.googleapis.com/v4/spreadsheets/SPREADSHEET_ID?includeGridData=false
I got a HTTP/1.1 200 OK and it displayed my requested data. This goes for all Spreadsheetv4 server-side processes.
Hope this helps.
We recently fixed this and it should now be working. Sorry for the troubles, please try again.
The document must be shared to "Anyone with the link" or "Public on the web". (Note: the publishing settings from "File -> Publish to the web" are irrelevant, unlike in the v3 API.)
This is not a solution of the problem but I think this is a good way to achieve the goal. On site http://embedded-lab.com/blog/post-data-google-sheets-using-esp8266/ I found how to update spreadsheet using Google Apps Script. This is an example with GET method. I will try to show you POST method with JSON format.
How to POST:
Create Google Spreadsheet, in the tab Tools > Script Editor paste following script. Modify the script by entering the appropriate spreadsheet ID and Sheet tab name (Line 27 and 28 in the script).
function doPost(e)
{
var success = false;
if (e != null)
{
var JSON_RawContent = e.postData.contents;
var PersonalData = JSON.parse(JSON_RawContent);
success = SaveData(
PersonalData.Name,
PersonalData.Age,
PersonalData.Phone
);
}
// Return plain text Output
return ContentService.createTextOutput("Data saved: " + success);
}
function SaveData(Name, Age, Phone)
{
try
{
var dateTime = new Date();
// Paste the URL of the Google Sheets starting from https thru /edit
// For e.g.: https://docs.google.com/---YOUR SPREADSHEET ID---/edit
var MyPersonalMatrix = SpreadsheetApp.openByUrl("https://docs.google.com/spreadsheets/d/---YOUR SPREADSHEET ID---/edit");
var MyBasicPersonalData = MyPersonalMatrix.getSheetByName("BasicPersonalData");
// Get last edited row
var row = MyBasicPersonalData.getLastRow() + 1;
MyBasicPersonalData.getRange("A" + row).setValue(Name);
MyBasicPersonalData.getRange("B" + row).setValue(Age);
MyBasicPersonalData.getRange("C" + row).setValue(Phone);
return true;
}
catch(error)
{
return false;
}
}
Now save the script and go to tab Publish > Deploy as Web App.
Execute the app as: Me xyz#gmail.com,
Who has access to the app: Anyone, even anonymous
Then to test you can use Postman app.
Or using UWP:
private async void Button_Click(object sender, RoutedEventArgs e)
{
using (HttpClient httpClient = new HttpClient())
{
httpClient.BaseAddress = new Uri(#"https://script.google.com/");
httpClient.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
httpClient.DefaultRequestHeaders.AcceptEncoding.Add(new System.Net.Http.Headers.StringWithQualityHeaderValue("utf-8"));
string endpoint = #"/macros/s/---YOUR SCRIPT ID---/exec";
try
{
PersonalData personalData = new PersonalData();
personalData.Name = "Jarek";
personalData.Age = "34";
personalData.Phone = "111 222 333";
HttpContent httpContent = new StringContent(JsonConvert.SerializeObject(personalData), Encoding.UTF8, "application/json");
HttpResponseMessage httpResponseMessage = await httpClient.PostAsync(endpoint, httpContent);
if (httpResponseMessage.IsSuccessStatusCode)
{
string jsonResponse = await httpResponseMessage.Content.ReadAsStringAsync();
//do something with json response here
}
}
catch (Exception ex)
{
}
}
}
public class PersonalData
{
public string Name;
public string Age;
public string Phone;
}
To above code NuGet Newtonsoft.Json is required.
Result:
If your feed is public and you are using api key, make sure you are throwing a http GET request.In case of POST request, you will receive this error.
I faced same.
Getting data using
Method: spreadsheets.getByDataFilter has POST request
Already few weeks i try sing up on SIP service with restcomm for android. I check connection with third-party application (cSipSimple) and everything works correctly. But when i try coonection with restcomm demo app, connection falls everytime after 4 seconds. Whats wrong with my sdk or how i can sing up right?
SipProfile sipProfile = new SipProfile();
HashMap<String, Object> params = new HashMap<String, Object>();
params.put("pref_proxy_ip", "my.server.ip");
params.put("pref_proxy_port", "5060");
params.put("pref_sip_user", "7879114");
params.put("pref_sip_password", "EeFei2Fa");
for (String key : params.keySet()) {
if (key.equals("pref_proxy_ip")) {
sipProfile.setRemoteIp((String) params.get(key));
} else if (key.equals("pref_proxy_port")) {
sipProfile.setRemotePort(Integer.parseInt((String) params.get(key)));
} else if (key.equals("pref_sip_user")) {
sipProfile.setSipUserName((String) params.get(key));
} else if (key.equals("pref_sip_password")) {
sipProfile.setSipPassword((String) params.get(key));
}
}
final SipManager sipManager = new SipManager(sipProfile, true);
Register registerRequest = new Register();
final Request r = registerRequest.MakeRequest(sipManager, 100000, null);
// Send the request statefully, through the client transaction.
Thread thread = new Thread() {
public void run() {
try {
final ClientTransaction transaction = sipManager.sipProvider.getNewClientTransaction(r);
transaction.sendRequest();
} catch (SipException e) {
e.printStackTrace();
}
}
};
thread.start();
#Vladislav, you are using the low level facilities of the SDK which are obsolete and not meant to be used directly. I would suggest that you use the RestCommClient API as exposed by the SDK directly. It is much easier to use and provides the same functionality and more.
For an example on how to use it please check:
https://github.com/RestComm/restcomm-android-sdk/blob/master/Examples/restcomm-helloworld/app/src/main/java/com/telestax/restcomm_helloworld/MainActivity.java
You need to change the SIP server settings from:
https://github.com/RestComm/restcomm-android-sdk/blob/master/Examples/restcomm-helloworld/app/src/main/java/com/telestax/restcomm_helloworld/MainActivity.java#L99
And the called party from:
https://github.com/RestComm/restcomm-android-sdk/blob/master/Examples/restcomm-helloworld/app/src/main/java/com/telestax/restcomm_helloworld/MainActivity.java#L174
Just keep in mind that for media Webrtc is used so that NATs can be handled properly. This means that the receiving party needs to be able to handle Webrtc as well. Unless there's a server in the middle handling the mediation, like Restcomm-Connect.
For more information please check RestComm Client Android SDK Quick Start
Is it possible to cancel HttpClient GET web request in Windows 8. I am looking for a solution to cancel my web request if the user press back key from the page. In my app i am using a static class for creating web request.
Alos i am using MVVM Light, and static viewmodels inside the app.
In the current situation, even if the user press the back button,
the vm stay alive and the call back reaches and executes in the VM.
So i am looking for a solution to cancel the request on back press.
Try this
protected async override void OnNavigatedTo(NavigationEventArgs e)
{
await HttpGetRequest();
}
public CancellationTokenSource cts = new CancellationTokenSource();
private async Task HttpGetRequest()
{
try
{
DateTime now = DateTime.Now;
var httpClient = new HttpClient();
var message = new HttpRequestMessage(HttpMethod.Get, "https://itunes.apple.com/us/rss/toppaidapplications/limit=400/genre=6000/json");
var response = await httpClient.SendAsync(message, cts.Token);
System.Diagnostics.Debug.WriteLine("HTTP Get request completed. Time taken : " + (DateTime.Now - now).TotalSeconds + " seconds.");
}
catch (TaskCanceledException)
{
System.Diagnostics.Debug.WriteLine("HTTP Get request canceled.");
}
}
private void btnCancel_Click(object sender, RoutedEventArgs e)
{
cts.Cancel();
}
The answer by #Farhan Ghumra is correct. Since we have moved to .Net 6 just like to add the following to the answer.
After you’re completely done with the CancellationTokenSource, dispose it directly E.g use cts.Dispose() (because you’ll most likely be using this with UI code and needing to share it with click event handling code, which means you wouldn’t be able to dispose of it with a using block)

I am having trouble with facebook authentication for Mobile Services in Azure.
To be more specific, I already have an application that is using Facebook C# SDK and it works fine. I can log on, fetch list of my friends and so. I want to keep using this SDK, but I also want to authenticate for Azure Mobile Service.
So, my plan was, log on with Facebook C# SDK (as I already do today), get the authentication token, and pass it to the MobileServiceClient.LoginAsync() - function. That way, I can still have all the nice features in Facebook C# SDK, and also use the built in authentication system in Mobile Services for Azure.
var client = new FacebookClient();
dynamic parameters = new ExpandoObject();
parameters.client_id = App.FacebookAppId;
parameters.redirect_uri = "https://www.facebook.com/connect/login_success.html";
parameters.response_type = "token";
parameters.display = "popup";
var loginUrl = client.GetLoginUrl(parameters);
WebView.Navigate(loginUrl);
When load is complete, followin is executed:
FacebookOAuthResult oauthResult;
if (client.TryParseOAuthCallbackUrl(e.Uri, out oauthResult) && oauthResult.IsSuccess)
{
var accessToken = oauthResult.AccessToken;
var json = JsonObject.Parse("{\"authenticationToken\" : \"" + accessToken + "\"}");
var user = await App.MobileService.LoginAsync(MobileServiceAuthenticationProvider.Facebook, json);
}
However, I get this exception when I call the last line of code above:
MobileServiceInvalidOperationException, "Error: The POST Facebook login request must specify the access token in the body of the request."
I cannot find any information on how to format the accesstoken, I have tried a lot of different keys (instead of "authenticationToken" as you see in my sample). I also have tried just to pass the accesstoken string, but nothing seem to work.
Also, if I use the MobileServiceClient.LoginAsync() for making a brand new login, it works just fine, but it seem silly to force users to log on twice.
Any help is greatly appreciated!
The format expected for the object is {"access_token", "the-actual-access-token"}. Once the login is completed using the Facebook SDK, the token is returned in the fragment with that name, so that's what the Azure Mobile Service expects.
BTW, this is a code which I wrote, based on your snippet, which works. It should handle failed cases better, though, but for the token format, this should be enough
private void btnLoginFacebookToken_Click_1(object sender, RoutedEventArgs e)
{
var client = new Facebook.FacebookClient();
dynamic parameters = new ExpandoObject();
parameters.client_id = "MY_APPLICATION_CLIENT_ID";
parameters.redirect_uri = "https://www.facebook.com/connect/login_success.html";
parameters.response_type = "token";
parameters.display = "popup";
var uri = client.GetLoginUrl(parameters);
this.webView.LoadCompleted += webView_LoadCompleted;
this.webView.Visibility = Windows.UI.Xaml.Visibility.Visible;
this.webView.Navigate(uri);
}
async void webView_LoadCompleted(object sender, NavigationEventArgs e)
{
AddToDebug("NavigationMode: {0}", e.NavigationMode);
AddToDebug("Uri: {0}", e.Uri);
string redirect_uri = "https://www.facebook.com/connect/login_success.html";
bool close = (e.Uri.ToString().StartsWith(redirect_uri));
if (close)
{
this.webView.LoadCompleted -= webView_LoadCompleted;
this.webView.Visibility = Windows.UI.Xaml.Visibility.Collapsed;
string fragment = e.Uri.Fragment;
string accessToken = fragment.Substring("#access_token=".Length);
accessToken = accessToken.Substring(0, accessToken.IndexOf('&'));
JsonObject token = new JsonObject();
token.Add("access_token", JsonValue.CreateStringValue(accessToken));
try
{
var user = await MobileService.LoginAsync(MobileServiceAuthenticationProvider.Facebook, token);
AddToDebug("Logged in: {0}", user.UserId);
}
catch (Exception ex)
{
AddToDebug("Error: {0}", ex);
}
}
}
Whenever you perform a Google search, it spits out this little snippet of info
"About 8,110,000 results (0.10 seconds)"
I'm using the number of results certain terms return to rank them against each other, so if I could get this integer - 8,110,000 - via the API it would be very helpful. Some Google API's have recently been deprecated, so if you could point me to the right one that isn't deprecated, it would be very helpful.
Any other workarounds would also be much appreciated. I've seen one or two old posts on similar topics, but none seemed to be resolved successfully.
Completed using Bing instead of Google and with the following code:
string baseURL = "http://api.search.live.net/xml.aspx?Appid=<MyAppID>&query=%22" + name + "%22&sources=web";
WebClient c = new WebClient();
c.DownloadStringAsync(new Uri(baseURL));
c.DownloadStringCompleted += new DownloadStringCompletedEventHandler(findTotalResults);
and this calls findTotalResults:
void findTotalResults(object sender, DownloadStringCompletedEventArgs e)
{
lock (this)
{
string s = e.Result;
XmlReader reader = XmlReader.Create(new MemoryStream(System.Text.UTF8Encoding.UTF8.GetBytes(s)));
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{
if (reader.Name.Equals("web:Total"))
{
gResults = reader.ReadInnerXml();
}
}
}
}
}
