Appeler des services web depuis MATLAB via HTTP

Communiquer avec des services web via HTTP (Hypertext Transfer Protocol)

Les fonctions MATLAB^® de services web RESTful webread, websave, webwrite et la fonction de support weboptions permettent aux utilisateurs sans compétences en programmation d’accéder à de nombreux services web avec les méthodes HTTP GET et POST. Pour plus d’informations sur ces fonctions, consultez Services web.

Toutefois, certaines interactions avec les services web sont plus complexes et nécessitent des fonctionnalités que les fonctions de services web RESTful ne supportent pas. L’interface HTTP de MATLAB propose des classes permettant d’écrire des applications d’accès web. Elle comprend des classes pour les messages, leurs en-têtes et leurs champs ainsi que les autres entités définies par les normes de l'IETF® (The Internet Engineering Task Force). Elle contient des fonctions qui implémentent la sémantique de messagerie HTTP ainsi que des utilitaires pour traiter les données envoyées et reçues. Elle contient également les classes de support requises pour traiter, émettre et recevoir des messages.

Les API de services web supportent uniquement HTTP 1.1.
