Examples of JsonWebSignature

com.google.api.client.auth.jsontoken.JsonWebSignature

.ietf.org/html/draft-ietf-jose-json-web-signature-00">JSON Web Signature (JWS).

Sample usage:

 public static void printPayload(JsonFactory jsonFactory, String tokenString) throws IOException { JsonWebSignature jws = JsonWebSignature.parse(jsonFactory, tokenString); System.out.println(jws.getPayload()); }

Implementation is not thread-safe.
