post with qt

Amanda0211

Hi
I am trying to make a post using qt with the following code:

QNetworkAccessManager manager;

QUrl url("http://192.168.4.1/post");
QNetworkRequest request(url);

request.setRawHeader("Content-Type", "text/plain");

QByteArray data("Hi");
QNetworkReply *reply = manager.post(request, data);

if(reply->error()){
    qDebug() << reply->errorString();
}

connect(reply, &QIODevice::readyRead, this, [=] {
    qDebug() << "Reply: " << reply->readAll();
});

The thing is that my server don't reply so i don´t know if I am posting with a incorrect format or if it is another problem.

When I use postman it works just fine!

The curl code with postman is this one:
curl --location --request POST 'http://192.168.4.1/post'
--header 'Content-Type: text/plain'
--data-raw 'Hi'

Try out:

QUrl url("http://192.168.4.1/post");
QNetworkRequest request(url);

request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");

QUrlQuery urlq;
urlq.addQueryItem ("Hi", "");

QNetworkReply *reply = manager.post(request, urlq.toString (QUrl::FullyEncoded).toUtf8 ());

while (!reply->isFinished())
{
	qApp->processEvents();
}

if(reply->error ()) qDebug ()<<reply->error();
else qDebug ()<<reply->readAll();

reply->deleteLater ();
