Detailed Description
This class holds the information necessary to perform a login on a server. Supported authentication mechanisms are
- Anonymous
- Username
- Certificate
The anonymous method is used by default but also can be set manually.
This is an example authentication using username and password.
QOpcUaAuthenticationInformation authInfo; authInfo.setUsernameAuthentication("user", "password"); m_client->setAuthenticationInformation(authInfo); m_client->connectToEndpoint(endpoint);
See also setAnonymousAuthentication(), setUsernameAuthentication(), and setCertificateAuthentication().
Member Function Documentation
QOpcUaAuthenticationInformation::QOpcUaAuthenticationInformation()
Default constructs an authentication information with no parameters set.
QOpcUaAuthenticationInformation::QOpcUaAuthenticationInformation(const QOpcUaAuthenticationInformation &rhs)
Constructs an authentication information from rhs.
const QVariant &QOpcUaAuthenticationInformation::authenticationData() const
The content of the QVariant returned by this method depends on the currently selected authentication method.
[invokable]
QOpcUaUserTokenPolicy::TokenType QOpcUaAuthenticationInformation::authenticationType() const
Returns the current authentication type.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
See also QOpcUaUserTokenPolicy::TokenType.

void QOpcUaAuthenticationInformation::setAnonymousAuthentication()
Sets the authentication method to anonymous.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
[invokable]
void QOpcUaAuthenticationInformation::setCertificateAuthentication()
Sets the authentication method to use certificates.
When using this authentication type a proper configured QOpcUaPkiConfiguration has to be set to the QOpcUaClient.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
See also QOpcUaPkiConfiguration and QOpcUaClient::setPkiConfiguration().
[invokable]
void QOpcUaAuthenticationInformation::setUsernameAuthentication(const QString &username, const QString &password)
Sets the authentication method to username, using the given username and password.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
QOpcUaAuthenticationInformation &QOpcUaAuthenticationInformation::operator=(const QOpcUaAuthenticationInformation &rhs)
Sets the values from rhs in this authentication information.
bool QOpcUaAuthenticationInformation::operator==(const QOpcUaAuthenticationInformation &rhs) const
Returns true
if this authentication information has the same value as rhs.
