Detailed Description
The QWebSocketCorsAuthenticator class provides an authenticator object for Cross Origin Requests (CORS).
The QWebSocketCorsAuthenticator class is used in the originAuthenticationRequired() signal. The class provides a way to pass back the required information to the QWebSocketServer. It provides applications with fine-grained control over which origin URLs are allowed and which aren't. By default, every origin is accepted. To get fine-grained control, an application connects the originAuthenticationRequired() signal to a slot. When the origin (QWebSocketCorsAuthenticator::origin()) is accepted, it calls QWebSocketCorsAuthenticator::setAllowed(true)
Note: Checking on the origin does not make much sense when the server is accessed via a non-browser client, as that client can set whatever origin header it likes. In case of a browser client, the server SHOULD check the validity of the origin.

Member Function Documentation
QWebSocketCorsAuthenticator::QWebSocketCorsAuthenticator(const QString &origin)
Constructs a new QCorsAuthencator object with the given origin.
Note: By default, allowed() returns true. This means that per default every origin is accepted.
QWebSocketCorsAuthenticator::QWebSocketCorsAuthenticator(const QWebSocketCorsAuthenticator &other)
Constructs a copy of other.
QWebSocketCorsAuthenticator::QWebSocketCorsAuthenticator(QWebSocketCorsAuthenticator &&other)
Move-constructs a QWebSocketCorsAuthenticator, making it point at the same object other was pointing to.
QWebSocketCorsAuthenticator::~QWebSocketCorsAuthenticator()
Destroys the object.
bool QWebSocketCorsAuthenticator::allowed() const
Returns true if the origin is allowed, otherwise returns false.
Note: By default, all origins are accepted.
See also setAllowed().
QString QWebSocketCorsAuthenticator::origin() const
Returns the origin this autenticator is handling about.
void QWebSocketCorsAuthenticator::setAllowed(bool allowed)
Allows or disallows the origin. Setting allowed to true, will accept the connection request for the given origin.
Setting allowed to false, will reject the connection request.
Note: By default, all origins are accepted.
See also allowed().
void QWebSocketCorsAuthenticator::swap(QWebSocketCorsAuthenticator &other)
Swaps other with this authenticator.
This operation is very fast and never fails.
QWebSocketCorsAuthenticator &QWebSocketCorsAuthenticator::operator=(QWebSocketCorsAuthenticator &&other)
Move-assigns other to this instance.
QWebSocketCorsAuthenticator &QWebSocketCorsAuthenticator::operator=(const QWebSocketCorsAuthenticator &other)
Assigns other to this authenticator object.
