Problems with HTTP-Query

kylecorver

Hi guys,
I'm having issues connecting to a webserver and sending a http-query. So far my code worked fine with websites that use the standard port. Additionally I now have to use a different port, now I'm having trouble to establish the connection. My Programcode looks like the following:

QEventLoop oEventLoop;

    QNetworkAccessManager oMgr;
    QObject::connect(&oMgr, SIGNAL(finished(QNetworkReply*)), &oEventLoop, SLOT(quit()));

    QUrl oUrl(QUrl("http://dummyurl.com"));
    oUrl.setPort(1234);
    QNetworkRequest oRequest(oUrl);
    oRequest.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");

    QUrlQuery oPostData;
    QJsonDocument oJsonQuery(aParams);
    oPostData.addQueryItem("query", oJsonQuery.toJson(QJsonDocument::Compact));

    QNetworkReply* pReply = oMgr.post(oRequest, oPostData.toString().toUtf8());
    oEventLoop.exec();

    if(pReply->error()!=QNetworkReply::NoError) {
        qDebug()<<pReply->errorString();
    }

At first I tried using QUrl oUrl(QUrl("http://dummyurl.com:1234"));, but this one wont' work, too.

What am I doing wrong?

Can you access that URL and port via a web browser?

and what exactly isn't working?! What do you expect and what do you get?

@jsulm Yeah URL and port are accessible via Webbrowser or php query, just the QT-Implementation can't establish a connection.

What is the output of this line:

qDebug()<<pReply->errorString();

@raven-worx I would expect some text as answer from the server. I do not get anything. While debugging I found out, that my program can't even connect to the Url. I'm sorry I forgot the error message:
"Connection timed out"
So I guessed there is anything wrong with my Code, because the URL is reachable via Webbrowser or for example php.

@jsulm As I said already in another answer, I'm sorry that I forgot that message:
"Connection timed out"
