Message header, specified as a matlab.net.http.HeaderField object or a vector of HeaderField objects. When you set the Header property, MATLAB® checks the fields of the header to ensure that they are appropriate for the message type. The RequestMessage send and complete methods fill in any required header fields for a properly formed request.

Attributes:

SetAccess
public

Message body, specified as a matlab.net.http.MessageBody object, matlab.net.http.io.ContentProvider, or data acceptable to the MessageBody constructor. By default, Body is empty (set to []). A request message containing a Body property normally uses a method such as 'PUT' or 'POST', not the default value 'GET', but this convention is not enforced.

In a completed or received message, if the message has a ContentTypeField header field, then the MessageBody.ContentType property is set to that value. Otherwise, ContentType is unchanged or empty.

Attributes:

Whether message is completed, specified as true or false. A true value means that the message was completed. Methods that return messages set the Completed property to true when:

  • The Body or Body.Data properties are empty.

  • The Body.Payload property contains the raw data.

Open Script

Send a message to the Hubble Heritage website requesting an image of Jupiter.

Format an HTTP request message and display the Content-Type of the response message body. The server returns a JPEG image.

request = matlab.net.http.RequestMessage;
uri = matlab.net.URI('http://heritage.stsci.edu/2007/14/images/p0714aa.jpg');
r = send(request,uri);
r.Body.ContentType

ans = 

  MediaType with properties:

          Type: "image"
       Subtype: "jpeg"
    Parameters: []
     MediaInfo: "image/jpeg"
        Weight: []

Display the image using the imshow function. MATLAB resizes the image to fit on the screen.

warning('off','Images:initSize:adjustingMag');
imshow(r.Body.Data)
