Qnetworkaccessmanager Implement Curl Upload form file

The process of sadness I will not say, direct serving.

How to use QT implementation: curl-f [email protected] Http://www.fatjb.com/uploadfile

Qfile file (M_staskplistpath), if (File.exists ()) {    if (!file.open (QIODevice::ReadOnly)) )     {        qmessagebox::warning (This, tr (" Warning "),  tr (" Open task.plist failed! "),  qmessagebox::yes);         return;    }     qbytearray filecontent = file.readall ();     File.close ();         qstring scrlf= "\ r \ n";     qsrand (Qdatetime::currentdatetime (). totime_t ());     qstring b=qvariant (Qrand ()) . ToString () +qvariant (Qrand ()). ToString () +qvariant (Qrand ()). ToString ();    qstring  sboundary= "---------------------------" +b;    qstring sendboundary=scrlf+ "--" + sboundary+ "--" +scrlf;    qstring scontenttype= "multipart/form-data; boundary=" +sboundary;    sboundary= "--" +sboundary+scrlf;    qbytearray  Boundary=sboundary.toascii ();        qbytearray senddata;     senddata.append (boundary);    sboundary = scrlf +  Sboundary;    boundary = sboundary.toascii ();     Senddata.append (QString ("content-disposition: form-data; name=\" file\ ";  filename=\" "+QString (m_ Staskplistpath.toutf8 (). Constdata ()) + "\" "+scrlf). Toascii ());     senddata.append (QString (" Content-transfer-encoding: 8bit "+scrlf). Toascii ());     senddata.append (SCrlf.toAscii ( );     senddata.append (filecontent);     senddata.append ( Sendboundary.toascii ());         qnetworkrequest req (QUrl (m_ Saddress+m_suploadpath));     req. SetHeader (Qnetworkrequest::contenttypeheader, scontenttype.toascii ());     Req.setheader (Qnetworkrequest::contentlengthheader, qvariant (Senddata.size ()). ToString ());     qnetworkreply* preply = m_pmanager->post (Req, senddata);     connect (preply, signal (Error (Qnetworkreply::networkerror)),  slot (networkerror:: Networkerror)));} Else{    qmessagebox::warning (THIS, TR ("Warning"),  tr ("Task.plist does not exist! "),  qmessagebox::yes);}

Why would I know? Next Wireshark grab the bag, then follow the correct package slowly tune to know, sure enough or not lazy.
