sxlfybb 2008-07-11 04:43:17

我给客户程序上传文件到youtube.但在上传文件最后一步，报错:417 Expectation Failed
折腾了三四天了，就这一个小问题，还是没解决掉。今天最后一天了，望大家帮我看看是什么问题。
以下是上传的源代码：

void StartUpload(CookieContainer cookie)

        {//cookie是以前已经获取到的登录cookie

            Dictionary<string, string> dic = new Dictionary<string, string>();

            dic.Add("field_command", "myvideo_submit");

            dic.Add("field_myvideo_keywords", info.Video.Tags);

            dic.Add("field_myvideo_title", info.Video.Title);

            dic.Add("field_myvideo_descr", info.Video.Description);

            dic.Add("field_myvideo_categories", info.Video.CateValue);

            dic.Add("language", "EN");

            dic.Add("field_privacy", "public");

            dic.Add("field_private_share_entities", "");

            dic.Add("addresser", urlenc);

            dic.Add("contact", "");

            dic.Add("field_date_day", "0");

            dic.Add("field_date_yr", "0");

            dic.Add("field_date_mon", "0");

            dic.Add("location", "");

            dic.Add("allow_comments", "Yes");

            dic.Add("allow_comment_ratings", "Yes");

            dic.Add("allow_responses", "Yes");

            dic.Add("allow_embedding", "Yes");

            dic.Add("allow_offweb", "Yes");

            dic.Add("allow_ratings", "Yes");

            dic.Add("allow_syndication", "Yes");

            //dic.Add("session_token", "n3jq1-akmi0yw725MxxR3vzbroR8MTIxNTg1MDA4NQ==");

            //dic.Add("field_uploadfile", string.Format("&field_uploadfile=filename=\"{0}\" Content-Type: text/plain", info.Video.Location));



            ArrayList bytesArray = new ArrayList();



            foreach (KeyValuePair<string, string> pair in dic)

            {//CreateFieldData是拿的宝玉的组装post数据的方法，可以在http://blog.joycode.com/dotey/archive/2005/04/17/49153.aspx里看到

                bytesArray.Add(CreateFieldData(pair.Key, pair.Value));

            }

            byte[] postArray = File.ReadAllBytes(info.Video.Location);

            bytesArray.Add(CreateFieldData("field_uploadfile", new FileInfo(info.Video.Location).Name, "text/plain", postArray));

            byte[] data = JoinBytes(bytesArray);

            string url = urladd;

            HttpWebRequest web = (HttpWebRequest)WebRequest.Create(url);

            if (ConnectionType == NetType.TOR)

                web.Proxy = new WebProxy("127.0.0.1", 8118);

            else if (ConnectionType == NetType.Proxy && this.Proxy != null)

                web.Proxy = this.Proxy;

            web.CookieContainer = cookie;

            web.Method = "POST";

            web.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; zh-CN; rv:1.9) Gecko/2008052906 Firefox/3.0";

            web.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

            web.Referer = "http://www.youtube.com/my_videos_upload";

            web.KeepAlive = true;

            web.ContentType = ContentType;



            //uploadFile(info.Video.Location, url, cookie,data);

            Stream sem;

            web.ContentLength = data.Length;

            sem = web.GetRequestStream();



            if (sem.CanWrite)

                sem.Write(data, 0, data.Length);

            sem.Close();



            HttpWebResponse res = (HttpWebResponse)web.GetResponse();//在这里报的错，

            cookie.Add(res.Cookies);

            Stream stream = res.GetResponseStream();

            string WebContent = new StreamReader(stream, System.Text.Encoding.Default).ReadToEnd();



            this.info.Finish(info);

            System.Threading.Thread.CurrentThread.Abort();

            // MessageBox.Show(WebContent);

            //Redirect to: http://www.youtube.com/my_videos_upload_complete?claim_video=&has_in_video_ads=&rev_share=0&video_id=NHOfkJxVzp4&rev_share_description=&has_afv_overlay=&action_from_upload=1

        }

分数不是问题，只要解决了，绝对加分。
