[C#][Windows Phone]利用WebCLient去完成Google Reader標記閱讀(Mark as read)

April 25th, 2012

上一篇文章有講解利用HttpWebRequest的方式來完成Google Reader中的標記閱讀，但是因為edit-tag本身就不屬於太消耗時間的動作。與其去用HttpWebRequest的非同步的方式，不如使用容易又好用的WebClient，所以我就把我原來程式碼做了一點修改。

 public void MarkArticleAsRead()
        {
            CurrentTransType = Transaction_Type.MARK_AS_READ;
            string auth_params = string.Format("https://www.google.com/reader/api/0/edit-tag?client=scroll&format=joson&ck=" + DateTime.Now.Ticks.ToString());

            string postData = "";
            postData += "&i=tag:google.com,2005:reader/item/fa42c976c848ecf4";
            postData += "&a=user/-/state/com.google/read";
            postData += "&s=feed/http://funiphone.pixnet.net/blog/feed/rss";
            // Note the token must get within 30 mins
            postData += "&T=//mUESPUMtDyZh6BaFXd-CqQ";


            WebClient wc = new WebClient();
            wc.Headers["Content-type"] = "application/x-www-form-urlencoded";
            wc.Headers["Authorization"] = "GoogleLogin auth=" + UserAuth;
            wc.Headers["Cookie"] = "SID=" + UserSid;
            try
            {
                wc.UploadStringAsync(new Uri(auth_params), "POST", postData);
            }
            catch (WebException e)
            {
                //handle error if any
            }
        }
<font face="Georgia">幾個需要注意的地方如下:</font>
  • UserAuth與UserSid 需要先對Google API做login的部分
  • Content-type是必須要先填成這樣，我試過uff8會失敗~
