See more HTTP Examples

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

require 'chilkat'

success = false

# 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." + "\n";
