Add Data to multipart/form-data Request

See more HTTP Examples

Demonstrates how to add content (such as a JPG, PDF, XML, etc.) to multipart/form-data requests. Perl

use chilkat();

$success = 0;

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

$req = chilkat::CkHttpRequest->new();
$req->put_HttpVerb("POST");
$req->put_ContentType("multipart/form-data");
$req->put_Path("/xyz/something");

$req->AddParam("param1","value1");
$req->AddParam("param2","value2");

# Add some small files to the request. (Small so we can see what the full request looks like without too much data..)
$bd = chilkat::CkBinData->new();
$success = $bd->LoadFile("qa_data/jpg/starfish20.jpg");
$req->AddBdForUpload("starfish20","starfish20.jpg",$bd,"image/jpeg");

$success = $bd->LoadFile("qa_data/pdf/helloWorld.pdf");
$req->AddBdForUpload("helloWorld","helloWorld.pdf",$bd,"application/pdf");

$success = $bd->LoadFile("qa_data/xml/tinyA.xml");
$req->AddBdForUpload("tinyA","tinyA.xml",$bd,"text/xml");

# This HTTP request contains binary data, so we cannot call GenerateRequestText
# to examine it as a string.  We can instead call GenerateRequestFile
# to write the request to a file and then examine using a hex editor,
# or an editor that is capable of handling null bytes and non-printable chars (perhaps by displaying "?" chars instead).
$req->GenerateRequestFile("qa_output/multipartFormDataRequest.bin");

print "OK." . "\r\n";
