void App::uploadImage(){
QString path(QDir::currentPath() + "/app/native/assets/Icon/img.jpg");
QNetworkRequest request(
QUrl( "http://domain.com?type=uploadimages&deviceid=12323"));
QByteArray boundary = "-------------------------32142544626177";
QFile file(path);
if (!file.open(QIODevice::ReadOnly)) {
qDebug() << "error read image";
return;
}
QByteArray fileContent(file.readAll());
QByteArray data = "--" + boundary + "\r\n";
data +=
"Content-Disposition: form-data; name=\"data\"; filename=\"img.jpg\";\r\n";
data += "Content-Type: image/jpg\r\n\r\n" + fileContent + "\r\n";
data += "--" + boundary + "--\r\n";
request.setRawHeader("Content-Type",
"multipart/form-data; boundary=" + boundary);
request.setRawHeader("Content-Length",
QString::number(data.size()).toAscii());
file.close();
qDebug() << "data" << data.size();
QNetworkAccessManager *am = new QNetworkAccessManager(this);
QNetworkReply *reply = am->post(request, "&data=" +data);
QObject::connect(am, SIGNAL(finished(QNetworkReply*)), this,
SLOT(replyFinished(QNetworkReply*)));
}
void App::replyFinished(QNetworkReply* reply) {
reply->open(QIODevice::ReadOnly);
if (reply->error() == QNetworkReply::NoError) {
QByteArray str = (reply->readAll());
QString response = QString::fromUtf8(str.data(), str.size());
qDebug() << " response " << response;
}
else{
qDebug() << "error response server";
}
}

QString body = "" ;
const QUrl url("http://someurl.to/make/the/post" );
QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);
QHttpPart textPartData;
body = "" ;
QTextStream(&body) << "";
textPartData.setHeader(QNetworkRequest::ContentTypeHeader, "application/json; charset=utf-8");
textPartData.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"data\""));
textPartData.setBody(body.toAscii());
for(int i=0; i< number_of_files_to_send ; i++){
QHttpPart imagePart;
QString header_body = "";
QTextStream(&header_body) << "form-data; name=\"" << name_of_the_file << "\"; filename=\"" << name_of_the_file << ".jpg\"" ;
imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(header_body));
imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpeg"));
//prepare file for upload
QString filepath;
QTextStream(&filepath) << FunkyPigeonBlackberry::getInstance()->dataModelProductDetails()->custom_image(i).value("cut_image").toString();
// pack the new file
QFile *file = new QFile(filepath);
file->open(QIODevice::ReadOnly);
imagePart.setBodyDevice(file);
file->setParent(multiPart); // we cannot delete the file now, so delete it with the multiPart
multiPart->append(imagePart);
}
multiPart->append(textPartData);
multiPart->append(textPartProductDetails);
multiPart->append(textPartDataDelivery);
QNetworkRequest request(url);
QNetworkReply* reply = m_networkAccessManager->post(request, multiPart);
connect(reply, SIGNAL(finished()), this, SLOT(onNetworkResponse()));
