我在一提供動態域名轉向服務的網站(www.3322.org)申請了一帳戶,現在我想把登入該網站然後更新IP的動作寫入到我的程序裡,不知可否做到?謝謝.

我知道該網站已有一客戶端軟件可做到以上動作,但我想自己寫,以下鏈接是相關協議,但我不知道怎麼用?

http://www.3322.org/dyndnspage/protocol.html

复杂的方式 tcp/ip http 按照 3322的格式发送

简单些的 idhttp 3322提供的 url (按其格式)

超简单的 webBrowser 访问 3322提供的 url (按其格式)

我找了些使用idhttp的資料,反覆測試後終於可以更新域名了(在使用idhttp的時候出現不明錯誤,所以改用ICS的httpcli控件),但還有個小問題:如何得到該網站返回的訊息?在登錄網站後可得到'200'的返回碼,但不一定代表域名更新成功,我要得到的是'Update Complete'或'good Update good and successful, IP updated'這樣的訊息.請再指教,謝謝.

以下是網站相關的返回碼解釋:
