Chiamata dei servizi web da MATLAB utilizzando HTTP

Comunicare con i servizi web utilizzando HTTP (Protocollo di trasferimento ipertesto)

Le funzioni MATLAB^® per i servizi web RESTful webread, websave, webwrite e la funzione di supporto weboptions consentono ai non programmatori di accedere a molti servizi web utilizzando i metodi HTTP GET e POST. Per informazioni su queste funzioni, vedere Servizi web.

Tuttavia, alcune interazioni con un servizio web sono più complesse e richiedono funzionalità non supportate dalle funzioni dei servizi web RESTful. L’interfaccia HTTP di MATLAB fornisce classi per la scrittura di applicazioni di accesso al web. L'interfaccia include classi per i messaggi, le loro intestazioni e campi e altre entità definite negli standard di The Internet Engineering Task Force (IETF®). L'interfaccia include funzioni che implementano la semantica della messaggistica HTTP e utilità per l'elaborazione dei dati inviati e ricevuti. Include inoltre le classi di supporto necessarie per elaborare, trasmettere e ricevere i messaggi.
