JWT(header: Object, payload: Object, signingKey: String, algorithm: String): String

Generate JWT with header, payload, and signature by specific algorithm.

Parameters

Example

This example shows how JWT behaves with the sample input.

Source

%dw 2.0
%dw 2.0
import jwt::HMAC
output application/json
---
HMAC::JWT({
            "header": "value"
          },
          {
            "firstName": "Michael",
            "lastName": "Jones"
          }, "secret", "HmacSHA384")

Output

"eyJhbGCI6IkpXVCJ9.eyJ4iLCJpYXQiOjE0MjI3Nzk2Mzh9.gzSraSYS8EXBxLN_oWnFSRgCz"

JWT(header: Object, payload: Object, signingKey: String): String
