详细描述

To allow web applications to access local files of the computer, applications must connect to QWebEnginePage::fileSystemAccessRequested, which takes a QWebEngineFileSystemAccessRequest instance as an argument.

If a web applications requests access to local files or directories, QWebEnginePage::fileSystemAccessRequested will be emitted with an QWebEngineFileSystemAccessRequest instance as an argument where accessFlags () indicates the type of the requested access: read, write or both. The signal handler needs to then either call accept () 或 reject ().
