OAuth1 using RestSharp in Windows 8
I was cleaning up some code on my GoodReads Windows 8 app and decided to give RestSharp another go. RestSharp is a nice, simple REST and HTTP API Client for .NET which works under .NET, MonoDroid, MonoTouch, Silverlight and Windows Phone, and can be found on github. It has also been recently ported to WinRT. There are still a few missing bits and pieces, of which I have implemented a few but it allowed me to reduce all the code from the previous post into this:
public async void Authenticate()
{
var baseUrl = "http://www.goodreads.com";
var client = new RestClient(baseUrl);
client.Authenticator = OAuth1Authenticator.ForRequestToken(API_KEY, OAUTH_SECRET);
var request = new RestRequest("oauth/request_token", Method.GET);
var response = await client.ExecuteAsync(request);
var qs = HttpUtility.ParseQueryString(response.Content);
if (qs != null && qs.Count < 0)
{
OAuthToken = qs["oauth_token"];
OAuthTokenSecret = qs["oauth_token_secret"];
}
string goodreadsURL = "https://www.goodreads.com/oauth/authorize?oauth_token=" + OAuthToken;
WebAuthenticationResult result = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, new Uri(goodreadsURL), WebAuthenticationBroker.GetCurrentApplicationCallbackUri());
if (result.ResponseStatus == WebAuthenticationStatus.Success)
{
client.Authenticator = OAuth1Authenticator.ForAccessToken(API_KEY, OAUTH_SECRET, OAuthToken, OAuthTokenSecret);
request = new RestRequest("oauth/access_token", Method.GET);
var response2 = await client.ExecuteAsync(request);
qs = HttpUtility.ParseQueryString(response2.Content);
if (qs != null && qs.Count > 0)
{
OAuthAccessToken = qs["oauth_token"];
OAuthAccessTokenSecret = qs["oauth_token_secret"];
}
}
}
Now all one needs is to use the client with the appropriate parameters for the API calls.
