[GFW BLOG] 同步消息到Twitter、新浪微博

来源：http://isouth.org/archives/302.html

有些东西，我也狠不下心来将他们干干净净地删除掉，所以我只能尽可能地去远离他们，于是，按照惯例，我又有机会来分享一下更新Twitter、新浪微博消息的代码了。（若有想要在 Twitter 上联系我的朋友，请直接使用 DM，这样我可以收到邮件通知）

提示：如果想要查看和同步相关的文章，可以直接点击这些文章的标签“一堆微博客”,可以查看文章的列表。

Twitter 更新消息时注意加入 postBody 参数就可以叻，更多细节可以对照 ”简版 OAuthr 认证 for C#“。

1. /// <summary>、
2. /// OAuth 认证更新twitter消息
3. /// </summary>
4. /// <param name="consumer_key">应用的consumer_key</param>
5. /// <param name="consumer_secret">应用的consumer_secret</param>
6. /// <param name="oauth_token">应用的access_key</param>
7. /// <param name="oauth_token_secret">应用的access_secret</param>
8. /// <param name="message">发送的消息</param>
9. /// <param name="request_path">请求的API</param>
10. private void update_twitter(
11.      string consumer_key,
12.      string consumer_secret,
13.      string oauth_token,
14.      string oauth_token_secret,
15.      string message,
16.      string request_path)
17. {
18.      string service = "推特";
19.      System.Net.ServicePointManager.Expect100Continue = false;
20.      this.BeginInvoke(new UpdateStatusDelegate(StateInfo), new object[] { "正在将消息发布到 " + service });
21.      string postData = "status=" + Utility.UrlEncode(message);
22.      byte[] bs = Encoding.UTF8.GetBytes(postData);
23.      Dictionary<string, string> param = new Dictionary<string, string>();
24.      param = OAuth.RequestParams(
25.          consumer_key,
26.          consumer_secret,
27.          oauth_token,
28.          oauth_token_secret,
29.          request_path,
30.          "POST",
31.          postData,
32.          null);
33.      string head_string = OAuth.Dict2Header(param);
34.      try
35.      {
36.          HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(request_path);
37.          request.ContentType = "application/x-www-form-urlencoded";
38.          request.Method = "POST";
39.          request.ContentLength = bs.Length;
40.          if (!string.IsNullOrEmpty(proxyserver))
41.          {
42.              request.Proxy = new WebProxy(proxyserver);
43.              ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);
44.          }
45.          request.Headers.Add("Authorization", "OAuth realm=\"http://t.yunmengze.net\"," + head_string);
46.          using (Stream reqStream = request.GetRequestStream())
47.          {
48.              reqStream.Write(bs, 0, bs.Length);
49.              reqStream.Close();
50.          }
51.      }
52.      catch (Exception e)
53.      {
54.          ErrorMessage("将消息发布到 " + service + " 时出现意外，建议暂时取消这一服务的同步:\r\n" + e.Message, 1);
55.          return;
56.      }
57. }

如果使用代理，加上一段

1. public bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
2. {
3.     //直接确认，否则打不开
4.     return true;
5. }

再是新浪微博的，其详细的规范我不太清楚，总之是在各种错误，各种失败之后尝试了将 OAuth 的参数（当然，也包括 postBody）直接 POST 出去，结果成功了。

1. /// <summary>
2. /// OAuth 认证更新sina消息
3. /// </summary>
4. /// <param name="consumer_key">应用的consumer_key</param>
5. /// <param name="consumer_secret">应用的consumer_secret</param>
6. /// <param name="oauth_token">应用的access_key</param>
7. /// <param name="oauth_token_secret">应用的access_secret</param>
8. /// <param name="message">发送的消息</param>
9. /// <param name="request_path">请求的API</param>
10. private void update_sina(
11.     string consumer_key,
12.     string consumer_secret,
13.     string oauth_token,
14.     string oauth_token_secret,
15.     string message,
16.     string request_path)
17. {
18.     string service = "新浪微博";
19.     System.Net.ServicePointManager.Expect100Continue = false;
20.     this.BeginInvoke(new UpdateStatusDelegate(StateInfo), new object[] { "正在将消息发布到 " + service });
21.     string postData = "status=" + Utility.UrlEncode(message);
22.     Dictionary<string, string> param = new Dictionary<string, string>();
23.     param = OAuth.RequestParams(
24.         consumer_key,
25.         consumer_secret,
26.         oauth_token,
27.         oauth_token_secret,
28.         request_path,
29.         "POST",
30.         postData,
31.         null);
32.     postData = OAuth.Dict2Result(param);
33.     byte[] bs = Encoding.UTF8.GetBytes(postData);
34.     try
35.     {
36.         HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(request_path);
37.         request.ContentType = "application/x-www-form-urlencoded";
38.         request.Method = "POST";
39.         request.ContentLength = bs.Length;
40.         using (Stream requestStream = request.GetRequestStream())
41.         {
42.             requestStream.Write(bs, 0, bs.Length);
43.             requestStream.Close();
44.         }
45.     }
46.     catch (Exception e)
47.     {
48.         ErrorMessage("将消息发布到 " + service + " 时出现意外，建议暂时取消这一服务的同步:\n" + e.Message, 1);
49.         return;
50.     }
51. }

在这里对 @yummy 表示抱歉，代码整理拖了很长时间。
