详细描述

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);
