Remove fields from message header
Description
Input Arguments
msg
— Message
matlab.net.http.Message
object
Message, specified as a matlab.net.http.Message
object.
ids
— Names to match
strings | matlab.net.http.HeaderField
objects | matlab.metadata.Class
objects
Names to match, specified as one of the following.
String vector, character vector, cell array of character vectors, or comma-separated list of strings or character vectors containing the names of the fields to remove. Names are not case-sensitive.
Vector or comma-separated list of one or more
HeaderField
objects whoseName
properties are used to determine which fields to remove. Names are not case-sensitive. Header field values are ignored.Vector or comma-separated list of
matlab.metadata.Class
objects that are subclasses ofHeaderField
.The
removeFields
method searches for names that match names supported by the specified classes, regardless of the class. If a subclass does not have a specific set of supported names, all header fields of that subclass are matched regardless of their names. Call theHeaderField.displaySubclasses
method to see supported names.
Example: getFields(response,'Date','Content-Type')
Examples
Remove Header Field from Request Message
Create a request message with two header fields, Cache-Control and Content-Type, and display the message.
import matlab.net.http.HeaderField m = matlab.net.http.RequestMessage('get'); f1 = HeaderField('Cache-Control','no-store, no-cache'); f2 = HeaderField('Content-Type','text/html;charset=utf-8'); m = addFields(m,f1,f2); show(m)
GET Cache-Control: no-store, no-cache Content-Type: text/html;charset=utf-8
Remove the Cache-Control field and display the updated message.
msg = removeFields(m,'Cache-Control');
show(msg)
GET Content-Type: text/html;charset=utf-8
Remove Header Field Subclasses
The MediaRangeField
class has two subclasses, AcceptField
and ContentTypeField
. An ID that specifies the MediaRangeField
class matches all fields of class MediaRangeField
, AcceptField
, and ContentTypeField
, plus any fields with the Name
property 'Accept'
or 'Content-Type'
.
Create message m
with a ContentTypeField
header field.
m = matlab.net.http.RequestMessage('get'); f = matlab.net.http.HeaderField('Content-Type','text/html;charset=utf-8'); m = addFields(m,f);
Remove all header fields that are subclasses of the MediaRangeField
class and display the updated message.
id = ?matlab.net.http.field.MediaRangeField; msg = removeFields(m,id); show(msg)
