Aufrufen von Web-Services aus MATLAB mittels HTTP

Kommunikation mit Webservices über HTTP (Hypertext Transfer Protocol)

Die MATLAB^® RESTful Webservice-Funktionen webread, websave und webwrite sowie die Support-Funktion weboptions ermöglichen den Zugriff auf zahlreiche Webservices über HTTP-GET- und POST-Methoden ohne Programmierkenntnisse. Informationen zu diesen neuen Funktionen finden Sie unter Web-Services.

Einige Interaktionen mit einem Webservice sind jedoch komplexer und erfordern Funktionen, die von den RESTful Web Services nicht unterstützt werden. Die HTTP-Schnittstelle von MATLAB stellt Klassen für das Verfassen von Webzugriffsanwendungen bereit. Die Schnittstelle enthält Klassen für Nachrichten, Nachrichtenheader und -felder sowie andere in den Standards der Internet Engineering Task Force (IETF®) definierte Einheiten. Die Schnittstelle enthält Funktionen, die die Semantik von HTTP-Nachrichten und -Dienstprogrammen für die Verarbeitung von gesendeten und empfangenen Daten implementieren. Sie enthält auch Supportklassen, die für die Verarbeitung, die Übertragung und den Empfang von Nachrichten erforderlich sind.
