using QT to send a HTTP post (text/xml or json or whatever), the post will be done as: a http packet, then a tcp packet which contains the real what i want to send out.
Why?
QUrl urlDigital("http://data.service.com");
QNetworkAccessManager *sfsmanager;
QNetworkRequest sfsrequest;
sfsrequest.setUrl(urlDigital);
sfsrequest.setHeader(QNetworkRequest::ContentTypeHeader,QVariant("multipart/form-data"));
sfsrequest.setHeader(QNetworkRequest::ContentLengthHeader, pstring.size());
sfsreply = sfsmanager->post(sfsrequest, pstring);
The post is like
