.Net OAuth Sample – Working with Justin.TV

This sample uses the excellent DevDefined OAuth .Net Implementation along with the Justin.TV rest apis for working with streaming and archived video.

Here’s some sample .net code to create a channel and user in justin.tv. The OAuthRequest wrapping class is then presented which acts as a core facade to justin.tv apis which secures the calls via a direct 2-legged request.

You should be able to modify the OAuthRequest and sample code for any OAuth based rest api as required.

Sample code to create new channel and user

// create new OAuthRequest and session
var oauthRequest = new OAuthRequest();
var oauthSession = oauthRequest.CreateSession();

// build up thepost  request
oauthSession.WithFormParameters(
	new
	{
		login = "[LOGIN]",
		password = "[PASSWORD]",
		birthday = "[DATEOFBIRTH]",
		email = "[EMAIL]",
		category = "[CATEGORY]",
		subcategory = "[SUBCATEGORY]",
		title = "[TITLE]",
		publisher_guard = "[PUBLISHER_GUARD]"
	}
);

// make the post request get the response as xml
HttpWebResponse results = oauthSession.Request().Post().ForUrl("http://api.justin.tv/api/channel/create.xml").ToWebResponse();
XDocument xdoc =oauthRequest.GetWebResponseAsXml(results);

// continue processing...
