Http Post Not Showing Content

so am trying to post to my localhost to get a result if it succeeded or not and I am having a problem. I think it's not sending the request or just not getting the result of the page. I added:

QT += network

but its still not working

void sendPost() {

QEventLoop eventLoop;
QNetworkAccessManager mgr;

QUrlQuery postData;
postData.addQueryItem("unm", "user");
postData.addQueryItem("pwd", "81238as");

QNetworkRequest request(QUrl(QString("http://localhost/login.php")));
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");

QNetworkReply *reply = mgr.post(request, postData.toString(QUrl::FullyEncoded).toUtf8());
eventLoop.exec();

if (reply->error() == QNetworkReply::NoError) {

    QString data = reply->readAll();
        qDebug(data.toUtf8().constData());
        delete reply;
}
else {
    qDebug() << "Failure" <<reply->errorString();
    delete reply;
  }
}

Thanks for your time.

You run eventLoop so it blocks all your app, you should quit from eventLoop when your manager is finished. Next code works but to be honest, I always do this with signals and slots so I don't know is usage of QEventLoop is correct approach.

Try this:

#include <QObject>
//...
QEventLoop eventLoop;
QNetworkAccessManager mgr;

QUrlQuery postData;
postData.addQueryItem("unm", "user");
postData.addQueryItem("pwd", "81238as");

QNetworkRequest request(QUrl(QString("http://localhost/login.php")));
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");

QNetworkReply *reply = mgr.post(request, postData.toString(QUrl::FullyEncoded).toUtf8());
QObject::connect(&mgr,SIGNAL(finished(QNetworkReply*)),&eventLoop,SLOT(quit()));
eventLoop.exec();

if (reply->error() == QNetworkReply::NoError) {

    QString data = reply->readAll();
        qDebug(data.toUtf8().constData());
        delete reply;
}
else {
    qDebug() << "Failure" <<reply->errorString();
    delete reply;
  }
