获取 oauth2 请求令牌

Question

我有 oauth 类，应该得到令牌。

它把味精放在控制台

GUI::GUI(QWidget *parent)
    : QWidget(parent)
    , ui(new Ui::GUI)
{
ui->setupUi(this);
this->oauth2 = new QOAuth2AuthorizationCodeFlow(this);
// Set auth uri, token, client data
//...
//

this->oauth2->setModifyParametersFunction([](QAbstractOAuth::Stage stage, QVariantMap* parameters) {
    // Here is important, there is no redirect, it just open new url with token
    (*parameters)["redirect_uri"] = QUrl("some:oauth:2.0:oob");
});

connect(this->oauth2, &QOAuth2AuthorizationCodeFlow::granted, [=](){
    qDebug() << __FUNCTION__ << __LINE__ << "Access Granted!";
});

connect(this->oauth2, &QOAuth2AuthorizationCodeFlow::authorizeWithBrowser, &QDesktopServices::openUrl);
this->oauth2->grant();
}

然后打开浏览器，同意后使用令牌重定向到页面。 我错过了哪里？
