Get the JWS Payload as a String

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.GetPayload, which returns the payload of a loaded JWS as text, decoded using the given charset.

Background. In practice, validate the signature before trusting the payload. Getting the payload retrieves the signed content.

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;

var jws = new CkJws();

//  Load the JWS compact serialization.
var jwsCompact = "eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>";
success = jws.LoadJws(jwsCompact);
if (success == false) {
    console.log(jws.LastErrorText);
    return;
}

//  Return the JWS payload as text, decoded using the given charset.
var payload = jws.GetPayload("utf-8");
if (jws.LastMethodSuccess == false) {
    console.log(jws.LastErrorText);
    return;
}

console.log(payload);
