HttpCalculatorWithUsernameOverSslClientExample

Artículo
06/13/2023

En este ejemplo se muestra un cliente HTTP que usa el proxy de servicio para comunicarse con un servicio de calculadora, con el nombre de usuario a través de la seguridad en modo mixto SSL. En esta configuración, la conexión de transporte está protegida (firmada, cifrada) por SSL, que también proporciona autenticación del servidor. La autenticación de cliente la proporciona un par de nombre de usuario y contraseña en un encabezado WS-Security en el mensaje.
