qt post and get request - qt

Question

I'm trying to log in to a webpage and then download some data that only members can download.
I've performed the post request and then the get request, for some reason the get request was finished first.
Is there any way to wait for the post to be finished or make it done first?
edit:
void downloader::LoginToHost()
{
QNetworkRequest request(QUrl("http://www.example.com/login.php"));
request.setHeader(QNetworkRequest::ContentTypeHeader,QVariant("application/x-www-form-urlencoded"));
QByteArray data("email=example&password=");
manager->post(request,data);
}
void downloader::Do_Request(QUrl url)
{
manager->get(QNetworkRequest(url));
}
void downloader::finished(QNetworkReply * reply)
{
QMessageBox mess;
if(reply->error() == QNetworkReply::NoError)
{
std::ofstream source("source-code.txt");
QString content = reply->readAll();
source << content.toStdString() << std::endl;
source.close();
mess.setText("Done download!");
}
else mess.setText(reply->errorString());
mess.exec();
}

Send the post and don't send the get until the post returns and triggers the finished signal in QNetworkReply.
Assuming there are two requests, one for the post and one for the get, which you've set up, here's an outline of what you can do: -
QNetworkRequst postRequest;
QNetworkRequest getRequest;
Sending the postRequest returns a QNetworkReply...
QNetworkAccessManager* networkAccessManager = new QNetworkAccessManager;
QNetworkReply postReply = networkAccessManager->post(postRequest, someData);
QNetworkReply getReply = nullptr; // C++ 11 nullptr
You can then connect to the postReply finished signal: -
// using a connection to a lambda function, send the get request when post has finished
connect(postReply, &QNetworkReply::finished, [this, networkAccessManager, getRequest, getReply](){
// handle the reply...
...
// send the getRequest
getReply = networkAccessManager->get(getRequest);
});
