Load MIME from BinData

Demonstrates the Chilkat Mime.LoadMimeBd method, which parses complete MIME bytes from a BinData and replaces the current MIME. The only argument is the BinData.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This is the safest loader because it works on raw bytes: MIME can carry 8-bit content and even embedded NUL bytes that a text string would mangle, so loading from a BinData preserves the message exactly. Prefer it whenever the input is binary or of uncertain encoding — a downloaded message, a file read as bytes — over the string-based loaders.

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 Mime.LoadMimeBd method, which parses complete MIME bytes from a BinData and
//  replaces the current MIME.  The only argument is the BinData.  This is the preferred loader
//  when the MIME may contain arbitrary 8-bit or embedded NUL bytes.

var bd = new CkBinData();
success = bd.LoadFile("qa_data/message.eml");
if (success == false) {
    console.log(bd.LastErrorText);
    return;
}

var mime = new CkMime();
success = mime.LoadMimeBd(bd);
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

console.log("Content-Type: " + mime.ContentType);
