如何使用 QT WebEngine 发送 HTTPHeader?

我正在使用 QT WebEngine 来制作一个适合我工作时需求的桌面网络浏览器.不幸的是，我需要将一些带有 HTTP 标头的数据发送到站点.我遇到了 QWebEngineUrlRequestInfo 类' void QWebEngineUrlRequestInfo::setHttpHeader(const QByteArray&name, const QByteArray &value) 方法，但我真的不知道如何在代码中使用它.到目前为止，这是我的代码:

I was playing around with QT WebEngine to make a desktop web browser which suits my requirements while working. Unfortunately, I need send some data with the HTTP Header to a site. I came across QWebEngineUrlRequestInfo class' void QWebEngineUrlRequestInfo::setHttpHeader(const QByteArray &name, const QByteArray &value) method but I don't really know how to use it in code. This is my code so far: 

import QtQuick 2.7
import QtQuick.Window 2.2
import QtQuick.Controls 2.0
import QtWebEngine 1.3

ApplicationWindow {
    visible: true
    width: 320
    height: 240
    title: qsTr("Browser")
    flags: Qt.WindowStaysOnTopHint

    WebEngineView {
        anchors.fill: parent
        url: "some http url here"
        Rectangle{
            height: 100
            width: height
        }
    }
}

这是我的 main.cpp 文件:

Here is my main.cpp file: 

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QtWebEngine/qtwebengineglobal.h>
#include <QWebEngineUrlRequestInfo>
#include <QByteArray>

int main(int argc, char *argv[])
{
    QByteArray key, value;
    key.append("SomeKey");
    value.append("SomeValue");
    QWebEngineUrlRequestInfo url;//Won't work because its constructor is private
    url.setHttpHeader(key, value);
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    QtWebEngine::initialize();
    engine.load(QUrl(QLatin1String("qrc:/main.qml")));

    return app.exec();
}

由于上面的代码抛出了一个错误，我实在想不出解决这个问题的办法.TIA

Since the above code throws an error, I really can't figure out a fix for this problem. TIA

推荐答案

这是我的小project 使用 webengine，仅供参考.

This is my tiny project using webengine, FYI.

view->page()->profile()->setRequestInterceptor(/*instance inerit QWebEngineUrlRequestInterceptor*/)
...
void /*class inerit WebEngineUrlRequestInterceptor*/::interceptRequest(QWebEngineUrlRequestInfo &info)
{
    info.setHttpHeader("Accept-Language", "zh-CN,zh;q=0.8");
}
