OneDrive API with C#, get authentication code programmatic

I have to write an application, no matter what language (c#, Java, shell, python ...) that can connect to OneDrive and then uploads file.
Following the OneDrive API I found that i need in one step to go to the browser (manually and to post a url that combines client_id and client_security to get an authentication code so i can connect my client with it to get the access token. (oAuth2 protocol)
I need to get the access_token pragmatically, i don't need any manual step to be involved.
I tried in c# to use the WebBrowser component to navigate to the url and to get the access token, I found that the browser stays in the same url and not getting the final url that includes the auth_code!
My code looks like:
// Initialize a new Client (without an Access/Refresh tokens
var client = new Client(options);
// Get the OAuth Request Url
var authRequestUrl = client.GetAuthorizationRequestUrl(new[] { Scope.Basic, Scope.Signin, Scope.SkyDrive, Scope.SkyDriveUpdate });
// TODO: Navigate to authRequestUrl using the browser, and retrieve the Authorization Code from the response
WebBrowser wb = new WebBrowser();
wb.AllowNavigation = true;
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Navigate(authRequestUrl);
Console.WriteLine(wb.Version);
while (wb.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
wb.Document.InvokeScript("evt_Login_onload(event)");
Uri myUrl = wb.Url;
Anyone can help with fixing this, or maybe suggest other ideas please?
Thanks in Advance!

It looks like you're creating a Windows desktop app using C#. There's actually an example at https://msdn.microsoft.com/en-us/library/hh826529.aspx for using the WebBrowser class to get the authorization code, then the token, then make an API. In short, you'll first need to send a request to the following URL with your client_id and scopes.
https://login.live.com/oauth20_authorize.srf?client_id=YOUR_CLIENT_ID&scope=YOUR_SCOPE_STRING&response_type=code&redirect_uri=https://login.live.com/oauth20_desktop.srf
In the response, you'll get the authorization code which you'll need to use to send another request to with your client_id, client_secret, authorization code like the following.
https://login.live.com/oauth20_token.srf?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&redirect_uri=https://login.live.com/oauth20_desktop.srf&code=AUTHORIZATION_CODE&grant_type=authorization_code
When you finally receive the access token, you can make requests to the API using your access token similar to the following.
"https://apis.live.net/v5.0/me?access_token=ACCESS_TOKEN". The "me" can be changed to any other folder or directory.
I hope that helps.

dont u think the scope u provided are wrong, they should be wl.basic, wl.signin, and if ur using new onedrive api then it should be onedrive.readonly or onedrive.readwrite
if ur using liveconnect api for the purpose of using onedrive then scope should be wl.skydrive or wl.contacts_skydrive or wl.skydrive_update
depending upon ur uses (refer https://msdn.microsoft.com/en-us/library/hh243646.aspx)
and can u more elaborate how ur trying to get the access_token, from above it is quite confusing to me

Have you solved you issue?
Have you tried to use the LiveSDK to authenticate?
Have a look at my question there, it might help you :
Onedrive API vs LiveSDK
I have used the following code, after installing both the LiveSDK and the OneDrive SDK, and this does not require any login after the first authorization. However it "may" have to be a RT app (windows store or windows phone store)
var authClient = new LiveAuthClient();
var authResult = await authClient.LoginAsync(new string[] {
"wl.signin", "onedrive.readwrite", "onedrive.appfolder"});
if (authResult.Session == null)
throw new InvalidOperationException("You need to sign in and give consent to the app.");
var Connection = new ODConnection("https://api.onedrive.com/v1.0",
new MicrosoftAccountAuthenticationInfo() { TokenType = "Bearer",
AccessToken = odArgs.Session.AccessToken });

Toan-Nguyen's answer almost helps me. On the step 2 (when I should send a request with authorization code) I get the response with error "Public clients can't send client secret". This answer said it's neccessary to remove the attribute client_secret from url.

Linq-to-Twitter always error 401 Unauthorized

I am using LinqToTwitter in my C# desktop application. Trying to send tweets and tweets with image to Twitter using OAuth credentials. Initially I am using these required attributes of my own Twitter application:
var auth = new SingleUserAuthorizer
{
Credentials = new SingleUserInMemoryCredentials
{
ConsumerKey = "key",
ConsumerSecret = "secret",
TwitterAccessToken = "token",
TwitterAccessTokenSecret = "tokensecret"
}
};
var context = new TwitterContext(auth);
context.UpdateStatus("Hello World");
NOTE: I have double checked that I am using correct values for above keys and tokens, but its always erroring 401 Unauthorized.
NOTE: Also I have checked this link for any mistake: http://linqtotwitter.codeplex.com/wikipage?title=LINQ%20to%20Twitter%20FAQ&referringTitle=Documentation
Any help to resolve this ?

Your code seems to be fine.
The FAQ, which you reference, is the best resource right now.
What type of application are you building, e.g. ASP.NET, Windows Phone, etc.?
You might also try downloading the source code and checking to see if the LinqToTwitterDemos project will work for you.

how to post on facebook wall for specific list of users using asp.net c#?

I am trying to post on specific group of users on facebook such as (close friends, or family, or college friend...) and I used the code bellow.
code that I used:
1
FacebookClient fpost1 = new FacebookClient(access_token);
fpost1.Post("/1234567890/feed", new { message = "test post"});
note: access_token is working correctly when I am doing some job before this exception.
I put my friendlist id instead of 1234567890, that you can get it from graph .../me?fields=friendlists
it did not work and gave me this error "(OAuthException - #2) An unexpected error has occurred. Please retry your request later."
2
FacebookClient fpost1 = new FacebookClient(access_token);
fpost1.Post("/me/feed", new { message = "it is very cold.", to="1234567890"});
this one work, but it post to "only me" as target.
thank you

It looks to me that what you are doing here...
FacebookClient fpost1 = new FacebookClient(access_token);
fpost1.Post("/1234567890/feed", new { message = "test post"});
is wrong. Because I believe that 1234567890 is a user-id, right? Not a friendslist-id. According to the documentation this edge/endpoint signature goes like....
/{user-id}/feed
where user-id is obviously a user id. The documentation states that...
Most nodes in the Graph API have edges that can be published to (such as Photos or Posts). All Graph API publishing is done simply with an HTTP POST request to the relevant endpoint with any necesssary parameters included. For example, if you wanted to publish a post on behalf of someone, you would make an HTTP POST request as below:
POST graph.facebook.com
/{user-id}/feed?
message={message}&
access_token={access-token}
Notice that it says "On Behalf of Someone". My understanding is that you are publishing on behalf of someone and to do that, this someone must have requested an access_token through your application. In other words, if this user hasn't logged in to your app and generated a valid access token you cannot publish on his/her wall

POST graph.facebook.com
me/feed?message="hello"&privacy={"value": "CUSTOM", "allow": "1234567890"}
where the 1234567890 is one of friendlists id

How do I resolve the OAuthException 100 Requires user session error when accessing Facebook?

I created my app and sent a request to Facebook with the following parameters:
facebookClient.AppId = APP_ID;
facebookClient.AppSecret = APP_SECRET;
facebookClient.AccessToken = APP_ACCESS_TOKEN;
However, when I try to get page statuses, I get the error:
OAuthException 100 Requires user session
What does this error mean? How do I resolve it?
Using a Facebook C# SDK to get this error.
The user that created this app has the manage_pages permission on the page I want to get status updates from.

To query for the "page statuses", you need to pass the user_access_token, not the app_access_token.
The user access token is obtained at the authorization step. For eg:
//authorization
session = await App.FacebookSessionClient.LoginAsync("manage_pages");
string access_token = session.AccessToken;
string fb_id = session.FacebookId;

DotNetOpenAuth with Google Calendar Feed

I have been racking my brain for a few days trying to get a list of calendars from Google using DotNetOpenAuth.
I can successfully get a list of contacts using the DotNetOpenAuth Samples. I have integrated it with my domain using the OpenId+OAuth. Everything works great to get a list of contacts.
So from there I modified the code to try to retrieve a list of Calendars and I keep getting a 401 Unauthorized error.
I know it is authorizing because I can get the contact list. Does anyone have a code example how they are retrieving calendars or calendar events using the DotNetOpenAuth with Google???
Thanks
Update:
Thanks for the response. I have read everything I can get my hands on. Here is what I have done so far
Step 1: I created a new GetCalendarEndPoint in the GoogleConsumer.cs
private static readonly MessageReceivingEndpoint GetCalendarEndpoint = new MessageReceivingEndpoint("https://www.google.com/calendar/feeds/default", HttpDeliveryMethods.GetRequest);
Step 2: Next I created a new method GetCalendars patterned after the GetContacts Method in GoogleConsumer.cs - (Rebuilt the dll etc.)
public static XDocument GetCalendars(ConsumerBase consumer, string accessToken, int maxResults/* = 25*/, int startIndex/* = 1*/) {
if (consumer == null)
{
throw new ArgumentNullException("consumer");
}
var request = consumer.PrepareAuthorizedRequest(GetCalendarEndpoint, accessToken);
var response = consumer.Channel.WebRequestHandler.GetResponse(request);
string body = response.GetResponseReader().ReadToEnd();
XDocument result = XDocument.Parse(body);
return result;
Step 3: In my Application I modified the ScopeURI to the the Calendar URI from GoogleConsumer as follows
private IAuthenticationRequest GetGoogleRequest()
{
Realm realm = Request.Url.Scheme + Uri.SchemeDelimiter + Global.GoogleTokenManager.ConsumerKey + "/";
IAuthenticationRequest authReq = relyingParty.CreateRequest(GoogleOPIdentifier, realm);
// Prepare the OAuth extension
string scope = GoogleConsumer.GetScopeUri(GoogleConsumer.Applications.Calendar);
Global.GoogleWebConsumer.AttachAuthorizationRequest(authReq, scope);
// We also want the user's email address
var fetch = new FetchRequest();
fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
authReq.AddExtension(fetch);
return authReq;
}
However, when I run the app I get 401 Unauthorized when I make the following call
var calendars = GoogleConsumer.GetCalendars(Global.GoogleWebConsumer, State.GoogleAccessToken, 25, 1);
I have also checked that the State.GoogleAccess token exists by simply displaying it on my screen before I trigger the method that makes this call.
Again, if I exectute
var calendars = GoogleConsumer.GetContacs(Global.GoogleWebConsumer, State.GoogleAccessToken, 25, 1);
then it works??????? Thanks for you help.

I've been suffering through exactly the same thing for most of the weekend.
I think that after much fiddling with Fiddler I've found the cause and have a solution which, although not pretty, seems to work. I found that I was able to access the calendar feed by copying and pasting the DNOA-generated Uri into a browser, but always got a 401 when attempting programmatic access. This is apparently because the default auto-redirect behavior of HttpWebRequest discards any cookies that the redirect is attempting to set. The Contacts feed doesn't set any cookies during the redirect, so it is immune.
The first time you request a calendar feed (even with a properly constructed and signed OAuth request), Google replies with a redirect containing a cookie. If you don't present that "calendar cookie" at the same time as your feed request you will get a 401 Unauthorized when you attempt to follow the redirect to the feed.
here's the cookie-setting header from Google:
HTTP/1.1 302 Moved Temporarily
Set-Cookie: S=calendar=y7AlfgbmcqYl0ugrF-Zt9A;Expires=Tue, 10-Jan-2012 03:54:20 GMT;Secure
Here's what I'm doing to make it work:
// wc: WebConsumer
var calRequest = wc.PrepareAuthorizedRequest(erp2, authTokenRsp.AccessToken);
// need to stop redirect to capture calendar cookie token:
calRequest.AllowAutoRedirect = false;
var calResponse = calRequest.GetResponse();
var redirectCookie = calResponse.Headers[System.Net.HttpResponseHeader.SetCookie];
var cookiedCalRequest = wc.PrepareAuthorizedRequest(erp2, authTokenRsp.AccessToken);
cookiedCalRequest.Headers[System.Net.HttpRequestHeader.Cookie] = redirectCookie;
var calFeedResponse = cookiedCalRequest.GetResponse();

Have you read the Google Calendar data API documentation to make sure you have the right endpoints programmed in? Have you also modified the code that acquires the access token to request access to Google Calendar in addition to Google Contacts? The access token in the sample only gets Contacts permissions unless you change it.
