Get the Value of a MIME Header Field

See more MIME Examples

Demonstrates how to get the value of a MIME header field. If the header field is not in the top-level MIME header, we must first navigate to the correct MIME part. Chilkat2 Perl

use strict;
use warnings;
use Chilkat2;

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

my $mime = Chilkat2::Mime->new;

# The contents of this MIME file are shown below,
# and is also available at https://www.chilkatsoft.com/sampleMime.txt
my $success = $mime->LoadMimeFile('qa_data/mime/sampleMime.txt');
if (!$success) {
    print $mime->LastErrorText, "\n";
    exit;
}

# The MIME used in this example has the following nested structure
#
# multipart/alternative
#     text/plain
#     multipart/related
#         text/html
#         image/jpeg
#

# Getting the content of a top-level MIME header is easy.
# MIME header fields are case insensitive.
print 'Subject = ', $mime->GetHeaderField('subject'), "\n";
print 'MIME-Version = ', $mime->GetHeaderField('mime-version'), "\n";

# To get a MIME header in a sub-part, first navigate to it..

my $mpRelated = Chilkat2::Mime->new;
$success = $mime->PartAt(1, $mpRelated);
if (!$success) {
    print $mime->LastErrorText, "\n";
    exit;
}

my $pJpg = Chilkat2::Mime->new;
$success = $mpRelated->PartAt(1, $pJpg);
if (!$success) {
    print $mpRelated->LastErrorText, "\n";
    exit;
}

print 'JPG Content-ID = ', $pJpg->GetHeaderField('content-id'), "\n";
print 'JPG Content-Type = ', $pJpg->GetHeaderField('content-type'), "\n";
