我正在尝试使用以下 twitter API,但无法获取用户状态。告诉我错误是什么?
WebClient connectTwitter = new WebClient();
connectTwitter.DownloadStringCompleted += new
DownloadStringCompletedEventHandler(connectTwitter_DownloadStringCompleted);
connectTwitter.DownloadStringAsync(new
Uri("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=BarackObama"));
