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 ().

enum QWebEngineFileSystemAccessRequest:: AccessFlag
flags QWebEngineFileSystemAccessRequest:: AccessFlags

This enum describes the type of the requested access: read, write or both. The options can be OR-ed together from the following list:

常量	值
QWebEngineFileSystemAccessRequest::Read	0x1
QWebEngineFileSystemAccessRequest::Write	0x2

The AccessFlags type is a typedef for QFlags <AccessFlag>. It stores an OR combination of AccessFlag values.

enum QWebEngineFileSystemAccessRequest:: HandleType

This enum describes the type of the requested file system entry.

常量	值
QWebEngineFileSystemAccessRequest::File	0
QWebEngineFileSystemAccessRequest::Directory	1
