Qt QNetworkAccessManager & multiple QNetworkReplay

Question

I have two http get methods.

First is getting UserID and second is getting full information about current user;

I want to handle finished signlas with different slots

handle GetUserID finished with GetUserIDCompleted and handle GetUserDetails with GetUserDetailsCompleted

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    nam = new QNetworkAccessManager(this);

    GetUserID();
    connect(nam, SIGNAL(finished(QNetworkReply*)), this, SLOT(GetUserIDCompleted(QNetworkReply*)));

    GetUserDetails();
    connect(nam, SIGNAL(finished(QNetworkReply*)), this, SLOT(GetUserDetailsCompleted(QNetworkReply*)));
}

does it possible to get QNetworkReplay in different SLOTS?

Answer 1

maybe you can do something like this: having an enum of the different methods

enum GetMethod
{
    getUserId,
    getUserDetails
};

And you keep a hash of the reply and the corresponding method:

QHash<QNetworkReply*, GetMethod> hash;

QNetworkReply *reply1 = nam->post(requestUserId, data);
hash[reply1] = GetMethod::getUserId;

QNetworkReply *reply2 = nam->post(requestUserDetails, data);
hash[reply2] = GetMethod::getUserDetails;

connect(nam, SIGNAL(finished(QNetworkReply*)), this, SLOT(finished(QNetworkReply*)));

And have one slot that calls the right function

void MainWindow::finished(QNetworkReply *reply)
{
    switch(hash[reply])
    {
    case GetMethod::getUserId:
        GetUserIDCompleted(reply);
        break;
    case GetMethod::getUserDetails:
        GetUserDetailsCompleted(reply);
        break;
    }

    hash.remove(reply);
}

I haven't tried it and took some shortcuts but you get the spirit of it =) . It seems that you can retrieve the request with the answer, but I think it is easier with the enum.

Hope it helped
