json - 解析 Twitter 时间线 json Windows Phone

Question

我正在尝试解析 Twitter 时间线，但出现错误：远程服务器返回错误：NotFound。

这是代码：

 private void GetUserTimeLine(string userName)
    {
        WebClient wcTwitterTimeline = new WebClient();
        wcTwitterTimeline.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wcTwitterTimeline_DownloadStringCompleted);
        wcTwitterTimeline.DownloadStringAsync(new System.Uri("http://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=" + userName));
    }

    void wcTwitterTimeline_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {


            List<RootObject> tweets = JsonConvert.DeserializeObject<List<RootObject>>(e.Result);
            this.listboxMyTimeline.ItemsSource = tweets;

            Dispatcher.BeginInvoke(() =>
            {
                listboxMyTimeline.Visibility = Visibility.Visible;
                txtBoxNewTweet.Visibility = Visibility.Visible;
                btnPostTweet.Visibility = Visibility.Visible;
            });
        }

错误从这里开始：

List<RootObject> tweets = JsonConvert.DeserializeObject<List<RootObject>>(e.Result);

Answer 1

404 Not Found 可能是因为您的 URL 方案是 http 并且应该是 https。解决此问题后，您的下一个错误可能是 401 Unauthorized，因为 Twitter API v1.1 需要 OAuth 身份验证。您可能需要查看Twitter API 常见问题解答和参考文档以获取更多详细信息。
