I have tried the following code for image uploading,in this code am able to get the response from server but the image size is always zero in server.Can anyone help me about this regards,


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";
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";

QNetworkAccessManager *am = new QNetworkAccessManager(this);
QNetworkReply *reply = am->post(request, "&data=" +data);

QObject::connect(am, SIGNAL(finished(QNetworkReply*)), this,
void App::replyFinished(QNetworkReply* reply) {

Re: Upload the image to server in blackberry 10 cascades?

I haven't tried the way you do, which you create a post request manually. But i have tried the multipart wich is easy and convient to use. Please check out this thread: http://supportforums.blackberry.com/t5/Cascades-Development/Upload-camera-image-Cascades-10-Beta-3/m...

Re: Upload the image to server in blackberry 10 cascades?

There is a good example on how to implement a post request.


    QFile fileUp("FILE PATH");
    QByteArray file(fileUp.readAll());
    QByteArray boundary("AaB03x");
    QNetworkRequest req(QUrl("https://evsweb39.idrive.com/evs/uploadFile"));
    req.setRawHeader("Content-Type", QByteArray("multipart/form-data; charset=UTF-8; boundary=") + boundary);
    QByteArray postData;
    postData += "--" + boundary + "\r\n";
    postData += "Content-Disposition: form-data; name=\"uid\"\r\n\r\n";
    postData += userName + "\r\n";
    postData += "--" + boundary + "\r\n";
    postData += "Content-Disposition: form-data; name=\"pwd\"\r\n\r\n";
    postData += passWord + "\r\n";
    postData += "--" + boundary + "\r\n";
    postData += "Content-Disposition: form-data; name=\"p\"\r\n\r\n";
    postData += remotePath + "\r\n";
    postData += "--" + boundary + "\r\n";
    postData += "Content-Disposition: form-data; filename=\"" + fileName + "\";\r\nContent-Type: application/octet-stream\r\n\r\n";
    postData += file;
    postData += "\r\n";
    postData += "--" + boundary + "--\r\n";
    req.setHeader(QNetworkRequest::ContentLengthHeader, QString::number(postData.length()));


This example is part of another forum thread.
