Get an Email's MIME into a BinData

Demonstrates the Chilkat Email.GetMimeBd method, which serializes the complete RFC822/MIME message (headers, body representations, related items, and attachments) and appends the bytes to a BinData object. This example builds a message, serializes it to a BinData, and prints the byte count.

Background: A BinData holds raw bytes, which is the right container when you want the MIME as binary rather than text — for example to write it directly to a file or socket, hash it, or hand it to another API that expects a byte buffer. It is the binary counterpart to GetMime (string) and GetMimeSb (StringBuilder).

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

//  Demonstrates the GetMimeBd method, which serializes the complete RFC822/MIME message
//  (headers, bodies, related items, and attachments) and appends the bytes to a BinData
//  object.

var email = new CkEmail();
email.Subject = "GetMimeBd example";
email.From = "alice@example.com";
email.AddTo("Bob","bob@example.com");
email.Body = "Hello!";

//  Append the complete MIME to a BinData object.
var bdMime = new CkBinData();
success = email.GetMimeBd(bdMime);
if (success == false) {
    console.log(email.LastErrorText);
    return true;
}

console.log("MIME size (bytes) = " + bdMime.NumBytes);
