matlab.net.http.field.ContentTypeField class

Package: matlab.net.http.field
Superclasses: matlab.net.http.HeaderField, matlab.net.http.field.MediaRangeField

HTTP Content-Type header field

Description

A ContentTypeField object is an HTTP header field in a request or response message. The field contains a single media type specification indicating the type of content in the body of the message.

In a request message, a Content-Type field determines how data specified in the MessageBody.Data property is converted. For information on this conversion, see HTTP Data Type Conversion. If a request message contains a nonempty body, but does not contain a Content-Type field, then MATLAB® creates a Content-Type field based on the data type.
