This example demonstrates how to parse an HTTP response that is multipart and contains a binary file, such as a .zip or .pdf. Chilkat2 Perl

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

my $http = Chilkat2::Http->new;
my $req = Chilkat2::HttpRequest->new;

# ...
# Insert code here to construct some kind of HTTP request.
# this example is to show how to parse a particular kind of response.
# ...
# ...

# Send the request (whatever it may be in your case) to get the HTTP response object.
my $resp = Chilkat2::HttpResponse->new;
my $success = $http->HttpSReq('www.somedomain.com', 443, 1, $req, $resp);
if (!$success) {

    exit;
}

# Get the response body (which is expected to be binary)
my $respBody = Chilkat2::BinData->new;
$resp->GetBodyBd($respBody);

# For this example, the response body contains something like this:

# ------=_Part_21302_2029949381.1547401515443
# Content-Type: application/xop+xml; charset=UTF-8; type="text/xml"
# Content-Transfer-Encoding: 8bit
# Content-ID: <rootpart@ws.jboss.org>
#
# <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'><env:Header></env:Header><env:Body>...</env:Body></env:Envelope>
# ------=_Part_21302_2029949381.1547401515443
# Content-Type: application/octet-stream
# Content-Transfer-Encoding: binary
# Content-Id: <fileArchivio-7d302908-4d64-43d3-bf4e-79ce806d43b3@ws.jboss.org>

# BINARY_CONTENT_HERE...

# Load it into a Chilkat MIME object.

# Get the 1st sub-part, which is the XML.

# Should be OK because we checked NumParts above..
