我recieving 502錯誤，從什麼應該是一個簡單的請求..WebClient的FTP/502錯誤
WebClient webClient = new WebClient();
SourceURL = string.Format(@"ftp://{0}/{1}", "ftp.cmegroup.com", "settle/nymex_option.csv"); //used field names ... but these are the values
webclient.Credentials = new NetworkCredential(@"anonymous", @"[email protected]");
webClient.DownloadFile(new Uri(SourceURL), "c:\temp\temp.dat");
我捕獲通過小提琴手發出的請求，它看起來像這樣在RAW檢查：
GET ftp://anonymous:anonymous%[email protected]/settle/nymex_option.csv HTTP/1.1
Host: ftp.cmegroup.com
Proxy-Connection: Keep-Alive
尋找想法，從哪裏開始就找出到底是怎麼回事....
