(Node.js) Uni Economy API Client Credentials Flow

Demonstrates how to do OAuth 2.0 using the client credentials flow for the Uni Economy API. (This means that the server can authenticate against the identity server without human interaction.)

For more information, see https://developer.unieconomy.no/wiki/introduction/getting-started/server-application

    // Also, if your .p12 password is longer than 64 chars, you'll need Chilkat v9.5.0.83 or later.
    // To shorten the password, import your .p12 onto your Windows computer by double-clicking on the .p12 file,
    // make sure when importing that keys are exportable, then re-export with private keys to a .pfx with a new password.

    success = jose.AppendString("alg","RS256");
    success = jose.AppendString("typ","JWT");

    // Now build the JWT claims (also known as the payload)

    // Our JWT claims will contain members as shown here:
    // {

    success = claims.AddIntAt(-1,"iat",curDateTime);

    // Set the "not process before" timestamp to now minus 60 seconds
    success = claims.AddIntAt(-1,"nbf",curDateTime);

    // Set the timestamp defining an expiration time (end time) for the token
    // to be now + 1 hour (3600 seconds)
