    @ali-aydin said in Sending parameters by get method to rest api:
    If you want your code to block until the reply has arrived, create an event loop on the stack, connect the network reply's finished signal to the quit slot of the event loop and exec() it.

    QUrl url("http://localhost:59444/api/Getmojodi");
      QNetworkRequest req1;
      const QByteArray basic_authorization =token.toUtf8().toBase64();
      req1.setRawHeader(QByteArrayLiteral("Authorization"), basic_authorization);
      QUrlQuery uq;
      uq.addQueryItem("KalaCode","20101010131310");
      url.setQuery(uq);
      req1.setUrl(url);
      QNetworkReply *rep= manager->get(req1);
      // blocking code starts here
      QEventLoop loop;
      QObject::connect(rep, &QNetworkReply::finished, &loop, &QEventLoop::quit);
      loop.exec();
      // end of blocking code
      QString val = rep->readAll();
      QJsonDocument jDoc=QJsonDocument::fromJson(val.toUtf8());
      QJsonObject obj = jDoc.object();
      qDebug()<<obj["mojodi"].toString();//is empty.

    but is not ok yet
    changed code:

        QUrl url("http://localhost:59444/api/Getmojodi");
        QNetworkRequest req1;
        const QByteArray basic_authorization =token.toUtf8().toBase64();

        QNetworkReply *rep= manager->get(req1);
        // blocking code starts here
        QEventLoop loop;
        QTimer timer;
        timer.setSingleShot(true);
    
        QObject::connect(&timer,&QTimer::timeout,&loop,&QEventLoop::quit);
        QObject::connect(rep, &QNetworkReply::finished, &loop, &QEventLoop::quit);
        timer.start(5000);
        loop.exec();
        // end of blocking code
        if(!timer.isActive())
        {
        QString val = rep->readAll();
        QJsonDocument jDoc=QJsonDocument::fromJson(val.toUtf8());
        QJsonObject obj = jDoc.object();

      You are not doing any error management so you can't know what is happening.

        if(!timer.isActive())

        qDebug()<<val;

        ... and additionally to @SGaist why not tell us whether it times out or what it outputs?

            Authentication, authorization and request management are three different stages that all can fail separately. The fact that you can authenticate does not mean that everything else is working.

                The best place is the documentation: QNetworkReply::errorOccured.

                  I changed slot that connected to finish signal like this :

                  QByteArray bytes = R->readAll();
                      QString str = QString::fromUtf8(bytes.data(), bytes.size());
                      int statusCode = R->attribute(QNetworkRequest::HttpStatusCodeAttribute).toInt();
                      qDebug() << QVariant(statusCode).toString();
                  

                  and return 403 code it means forbidden.why?

                    403 is what your server sends. It means that your parameters are incorrect or the server itself has (due to misconfiguration) no access to the requested resource.
                    Have you tried the call with postman or a browser?

                        Your platform/web server may/should have the ability to log all requests/responses to a log file? You might switch that on and see if anything helpful there?

                                I think you have to add 'Basic ' before your token when you set the Authorization header (or 'Bearer ' if you are doing bearer token auth). If things are working in Postman, check the 'Headers' tab of your request as to what is the actual value being sent for the Authorization.

                                  Bearer must be added to the token.
                                  in postman there is no header
                                  in authorization tab
                                  only added token and in parameters tab is only one parameter :KalaCode
                                  in body tab username,password and grant_type
                                  in the qt when I want to authenticate by

                                  QUrl url("http://localhost:594444/api/authenticate");
                                  

                                  it returns "Hello"
                                  but when i changing url to

                                  QUrl url("http://localhost:594444/api/Getmojodi" );
                                  

                                  it does not work

                                    I meant the 'Headers' tab of the Postman request:
                                    b0973db6-0abc-4a60-9d8e-5e0955d007f9-image.png

                                    The authorization header value above was automatically set when I added a (junk) username and password in the Auth tab:

                                    a33e651c-8868-47c3-b96e-f7569e008cc0-image.png

                                      The authorization header value above was automatically set when I added a (junk) username and password in the Auth tab:

                                        Are you setting the Authorization the same in Qt as the value it is set in Postman? Your variables are 'basic_authorization' and 'token', is token just the token or is the token type prepended to it ('Basic ' or 'Bearer ')? Your variable is 'basic_authorization' but in your prior message, you mention adding 'Bearer' before the token, which auth method are you using?

                                          and adding bearer to token
