URL-Encode a MIME Body

Demonstrates the Chilkat Mime.UrlEncodeBody method, which replaces the current body with an application/x-www-form-urlencoded-style representation using the named charset. The only argument is the charset; it is a void method.

Background: This transforms the body into the form-encoding used by HTML form submissions — spaces to +, reserved characters to percent-escapes — interpreting the text through the given charset first so non-ASCII characters encode correctly. It is a niche operation for constructing form-style payloads within a MIME part.

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.UrlEncodeBody method, which replaces the current body with an
//  application/x-www-form-urlencoded representation using the named charset.  The only argument is
//  the charset.  It is a void method.

var mime = new CkMime();

success = mime.SetBodyFromPlainText("name=John Doe & city=New York");
if (success == false) {
    console.log(mime.LastErrorText);
    return;
}

//  URL-encode the body: spaces become "+", reserved characters become %-escapes.
mime.UrlEncodeBody("utf-8");

var encodedBody = mime.GetBodyDecoded();
if (mime.LastMethodSuccess == false) {
    console.log(mime.LastErrorText);
    return;
}

console.log(encodedBody);
