读取qt webengine中的http标头

#include <QtWebEngineWidgets>

#include <QNetworkReply>

// 槽函数，用于处理HTTP请求完成的信号
void replyFinished(QNetworkReply *reply) {
    // 获取HTTP标头的原始数据
    QByteArray headerData = reply->rawHeader();

    // 将原始数据分割成行
    QList<QByteArray> headerLines = headerData.split('\n');

    // 遍历每一行标头
    foreach (QByteArray line, headerLines) {
        // 解析标头名称和值
        int colonIndex = line.indexOf(':');
        if (colonIndex != -1) {
            QByteArray name = line.left(colonIndex).trimmed();
            QByteArray value = line.mid(colonIndex + 1).trimmed();

            // 在这里可以对标头进行处理或打印输出
            qDebug() << "Header: " << name << "Value: " << value;
        }
    }
