I've been having some issues trying to upload files to a server using QNetworkRequest. I've been using this link (http://qt-project.org/forums/viewthread/11361) mostly as a template, but am still getting POST errors (203 to be specific). Here is what I have so far.
void MainWindow::processFile(){
QByteArray postData;
//Look below for buildUploadString() function
postData = mReport->buildUploadString();
QUrl mResultsURL = QUrl("http://" + VariableManager::getInstance()->getServerIP() + "/uploadFile.php");
QNetworkAccessManager* mNetworkManager = new QNetworkAccessManager(this);
QString bound="margin"; //name of the boundary
QNetworkRequest request(mResultsURL); //our server with php-script
request.setRawHeader(QString("Content-Type").toAscii(),QString("multipart/form-data; boundary=" + bound).toAscii());
request.setRawHeader(QString("Content-Length").toAscii(), QString::number(postData.length()).toAscii());
connect(mNetworkManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(printScriptReply(QNetworkReply*))); //This slot is used to debug the output of the server script
mNetworkManager->post(request,postData);
}
QByteArray ReportParser::buildUploadString()
{
QString path = VariableManager::getInstance()->getReportDirectory();
path.append("\\\\");
path.append(getReportFileName());
QString bound="margin";
QByteArray data(QString("--" + bound + "\r\n").toAscii());
data.append("Content-Disposition: form-data; name=\"action\"\r\n\r\n");
data.append("uploadFile.php\r\n");
data.append(QString("--" + bound + "\r\n").toAscii());
data.append("Content-Disposition: form-data; name=\"uploaded\"; filename=\"");
data.append(getReportFileName());
data.append("\"\r\n");
data.append("Content-Type: text/xml\r\n\r\n"); //data type
QFile file(path);
if (!file.open(QIODevice::ReadOnly)){
qDebug() << "QFile Error: File not found!";
return data;
} else { qDebug() << "File found, proceed as planned"; }
data.append(file.readAll());
data.append("\r\n");
data.append("--" + bound + "--\r\n"); //closing boundary according to rfc 1867
file.close();
return data;
}
Here is the script on the server to process the file:
<?php
$uploaded_type = $_FILES['uploaded']['type'];
$target = "/var/www/webpage/results/";
$target = $target . basename( $_FILES['uploaded']['name']) ;
$ok=1;
echo "target: ";
echo $target;
//This is our limit file type condition
if ($uploaded_type =="text/xml"){
echo "We have an xml file!\r\n";
}
//Here we check that $ok was not set to 0 by an error
//If everything is ok we try to upload it
if ($ok==0){
echo "Sorry your file was not uploaded";
} else {
echo "Looking good!";
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)){
echo "The file successfully ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
} else {
echo "Sorry, there was a problem uploading your file.";
}
}
?>
I know that the script works, as it will handle the file properly when using a basic HTML form. However, the Qt side of things keeps returning POST errors.
Problem was dropped packets on the network. The above code actually works.
