Authenticate and request a user's timeline with Twitter API 1.1 oAuth


Here is what I did to get this working in a simple example.

I had to generate an oAuth consumer key and secret from Twitter at:

https://dev.twitter.com/apps/new

I deserialized the authentication object first to get the token and type back in order to authenticate the timeline call.

The timeline call simply reads the json as that is all I need to do, you may want to deserialize it yourself into an object.

I have created a project for this at : https://github.com/andyhutch77/oAuthTwitterWrapper

Update - I have updated the github project to include both asp .net web app & mvc app example demos and nuget install.

// You need to set your own keys and screen namevar oAuthConsumerKey = "superSecretKey";var oAuthConsumerSecret = "superSecretSecret";var oAuthUrl = "https://api.twitter.com/oauth2/token";var screenname = "aScreenName";// Do the Authenticatevar authHeaderFormat = "Basic {0}";var authHeader = string.Format(authHeaderFormat,    Convert.ToBase64String(Encoding.UTF8.GetBytes(Uri.EscapeDataString(oAuthConsumerKey) + ":" +    Uri.EscapeDataString((oAuthConsumerSecret)))));var postBody = "grant_type=client_credentials";HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(oAuthUrl);authRequest.Headers.Add("Authorization", authHeader);authRequest.Method = "POST";authRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";authRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;using (Stream stream = authRequest.GetRequestStream()){    byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);    stream.Write(content, 0, content.Length);}authRequest.Headers.Add("Accept-Encoding", "gzip");WebResponse authResponse = authRequest.GetResponse();// deserialize into an objectTwitAuthenticateResponse twitAuthResponse;using (authResponse){    using (var reader = new StreamReader(authResponse.GetResponseStream())) {        JavaScriptSerializer js = new JavaScriptSerializer();        var objectText = reader.ReadToEnd();        twitAuthResponse = JsonConvert.DeserializeObject<TwitAuthenticateResponse>(objectText);    }}// Do the timelinevar timelineFormat = "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name={0}&include_rts=1&exclude_replies=1&count=5";var timelineUrl = string.Format(timelineFormat, screenname);HttpWebRequest timeLineRequest = (HttpWebRequest)WebRequest.Create(timelineUrl);var timelineHeaderFormat = "{0} {1}";timeLineRequest.Headers.Add("Authorization", string.Format(timelineHeaderFormat, twitAuthResponse.token_type, twitAuthResponse.access_token));timeLineRequest.Method = "Get";WebResponse timeLineResponse = timeLineRequest.GetResponse();var timeLineJson = string.Empty;using (timeLineResponse){    using (var reader = new StreamReader(timeLineResponse.GetResponseStream()))    {         timeLineJson = reader.ReadToEnd();    }}public class TwitAuthenticateResponse {    public string token_type { get; set; }    public string access_token { get; set; }}


Created a JS only solution to get Twitter posts on your site without using new API - can now specify number of tweets too: http://goo.gl/JinwJ
