"ERR_NETWORK_ACCESS_DENIED" appears when loading local HTML with QWebEngineView

Buns

The C++ source code is as follows:

QVBoxLayout *layout = new QVBoxLayout;
m_view = new QWebEngineView();
layout->addWidget(m_view);
ui->widget->setLayout(layout);

QString filepath = qApp->applicationDirPath() + "/test.html";
m_view->load(QUrl(filepath));

and the HTML file is as follows:

<!DOCTYPE html> 
<html lang="en"> 
<head> 
	<meta charset="UTF-8"> 
	<meta http-equiv="refresh" content="0;url=http://baidu.com/"> 
</head> 
<body> </body> 
</html>

When the program was running, an error occurred：

"Please, could anyone tell me how to solve this issue? I would be very grateful."

I have already solved this problem. The solution is:

m_view->settings()->setAttribute(QWebEngineSettings::LocalContentCanAccessRemoteUrls, true);
