A request for providing authentication credentials required by proxies or HTTP servers. More...

Import Statement: import QtWebEngine
Since: QtWebEngine 1.4



Detailed Description

An AuthenticationDialogRequest is passed as an argument of the WebEngineView::authenticationDialogRequested signal. It is generated when basic HTTP or proxy authentication is required. The type of authentication can be checked with the type property.

The accepted property of the request indicates whether the request is handled by the user code or the default dialog should be displayed. If you set the accepted property to true, make sure to call either dialogAccept() or dialogReject() afterwards.

The following code uses a custom dialog to handle the request:

WebEngineView {
    // ...
    onAuthenticationDialogRequested: function(request) {
        request.accepted = true;
        myDialog.request = request // keep the reference to the request
        myDialog.visible = true;
    // ...

Property Documentation

accepted : bool

Indicates whether the authentication dialog request has been accepted by the signal handler.

If the property is false after any signal handlers for WebEngineView::authenticationDialogRequested have been executed, a default authentication dialog will be shown. To prevent this, set request.accepted to true.

The default is false.

[read-only] proxyHost : string

The hostname of the authentication proxy. Empty if type is AuthenticationTypeHTTP.

[read-only] realm : string

The HTTP authentication realm attribute value of the WWW-Authenticate header. Empty if type is AuthenticationTypeProxy.

[read-only] type : enumeration

The type of the authentication request.

Constant Description
WebEngineAuthenticationDialogRequest.AuthenticationTypeHTTP HTTP authentication.
WebEngineAuthenticationDialogRequest.AuthenticationTypeProxy Proxy authentication.

[read-only] url : url

The URL of the HTTP request for which authentication was requested. In case of proxy authentication, this is a request URL which is proxied via host.

See also proxyHost.
