I am developing social networks integration for my asp.net mvc4 application.
Twitter and Facebook were very easy for me but I am seriously stuck with LinkedIn.
Here is my code.
public ActionResult LinkedInTest(string text)
{
var client = new RestClient
{
Authority = "https://api.linkedin.com/uas/oauth",
Credentials = LinkedInSocialHelper.GetCredentials()
};
var request = new RestRequest {Path = "requestToken"};
RestResponse response = client.Request(request);
token = response.Content.Split('&')[0].Split('=')[1];
tokenSecret = response.Content.Split('&')[1].Split('=')[1];
textToPost = text;
Response.Redirect("https://api.linkedin.com/uas/oauth/authorize?oauth_token=" + token + "&scope=r_basicprofile+r_emailaddress+r_network+r_contactinfo+rw_nus");
return null;
textToPost = text;
return RedirectToAction("LinkedInCallback");
}
public ActionResult LinkedInCallback()
{
verifier = Request["oauth_verifier"];
var client = new RestClient
{
Authority = "https://api.linkedin.com/uas/oauth",
Credentials = LinkedInSocialHelper.GetCredentials(token, tokenSecret, verifier),
Method = WebMethod.Post
};
var request = new RestRequest {Path = "accessToken"};
RestResponse response = client.Request(request);
token = response.Content.Split('&')[0].Split('=')[1];
tokenSecret = response.Content.Split('&')[1].Split('=')[1];
LinkedInSocialHelper.Post(textToPost, token, tokenSecret);
return RedirectToAction("Calendar");
}
public static void Post(string text, string accessToken, string accessTokenSecret)
{
var tokenManager = new TokenManager(ApiKey, ApiSecret);
tokenManager.ExpireRequestTokenAndStoreNewAccessToken(null, null, accessToken, accessTokenSecret);
var authorization = new WebOAuthAuthorization(tokenManager, UserToken);
LinkedInService service = new LinkedInService(authorization);
//var user = service.GetCurrentUser(ProfileType.Public); - IT IS GIVING ME THE SAME ERROR - Access denied
service.CreateShare(text, VisibilityCode.ConnectionsOnly);
}
Everything works fine except last thing - posting shares - I get Access to posting shares denied exception despite the fact that I generate token using all the necessary permissions:
"https://api.linkedin.com/uas/oauth/authorize?oauth_token=" + token + "&scope=r_basicprofile+r_emailaddress+r_network+r_contactinfo+rw_nus"
Hope you good guys help me.
