How to wait until the request has finished and then process the reply within one fn

[vinayaka]

hai,

void HttpPost::on_pushButton_clicked()
   {
     params.addQueryItem("testSample","indu");
     postData = params.encodedQuery();
     manager->setCookieJar(new QNetworkCookieJar(manager));
     connect (manager, SIGNAL(finished(QNetworkReply *)), this, SLOT(replyFinish(QNetworkReply*)));
     manager->post(req, postData);
 
    }

void HttpPost::on_pushButton_clicked()
   {
     params.addQueryItem("testSample","indu");
     postData = params.encodedQuery();
     manager->setCookieJar(new QNetworkCookieJar(manager));
     connect (manager, SIGNAL(finished(QNetworkReply *)), this, SLOT(replyFinish(QNetworkReply*)));
     manager->post(req, postData);

    }

To copy to clipboard, switch view to plain text mode 

void HttpPost::replyFinish(QNetworkReply* reply)
   {
 
    QString answer = QString::fromUtf8(reply->readAll());
    qDebug() << "answer------------>"<<answer;
 
   }

void HttpPost::replyFinish(QNetworkReply* reply)
   {

    QString answer = QString::fromUtf8(reply->readAll());
    qDebug() << "answer------------>"<<answer;

   }

This code is working for me but i don't want to use the "connect" here. I want the reply in the same function. I used
if (reply->isFinished()==true) but it doesnt work
