    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:

                          there is no problem in postman
                          problem is that how can we do authorization in qt?

                            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?

                                Are you doing Basic (username/password) or Bearer Token? What method are you selecting in Postman? What is the value of your token variable, post the string but modify the actual token part.

                                        Try

                                        QString token = <access_token from file>
                                        token.prepend("Bearer ");
                                        req1.setRawHeader(QByteArrayLiteral("Authorization"), token.toUtf8());
                                        

                                        I don't think you want the 'toBase64()' that you have in your code above.
