//pro中添加QT += webenginewidgets  webengine
//main中在开头添加QtWebEngine::initialize();

运行时发现这段代码在windows能够正常加载网页，但是在ubuntu显示加载进度为100%，但它不显示添加 qputenv("QTWEBENGINE_DISABLE_SANDBOX", "1");后解决

 QProcessEnvironment env = QProcessEnvironment::systemEnvironment();
    env.insert("QTWEBENGINE_CHROMIUM_FLAGS",

               "--ignore-gpu-blacklist "      // 忽略 GPU 黑名单（强制使用 GPU）
               "--enable-accelerated-video-decode "  // 启用硬件视频解码
               "--disable-software-rasterizer");     // 禁用软件光栅化（强制用 GPU）
    qputenv("QTWEBENGINE_CHROMIUM_FLAGS", env.value("QTWEBENGINE_CHROMIUM_FLAGS").toUtf8());
    qputenv("QTWEBENGINE_DISABLE_SANDBOX", "1");
    QtWebEngine::initialize();
    QApplication app(argc, argv);
