(JavaScript) Add Data to multipart/form-data Request
Demonstrates how to add content (such as a JPG, PDF, XML, etc.) to multipart/form-data requests.
var success = false;
// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var req = new CkHttpRequest();
req.HttpVerb = "POST";
req.ContentType = "multipart/form-data";
req.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..)
var bd = new CkBinData();
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");
console.log("OK.");
// This is the HTTP multipart/form-data request built by the above code:
