# ratpack-jwt-example

[![Build Status](https://travis-ci.org/gregwhitaker/ratpack-jwt-example.svg?branch=master)](https://travis-ci.org/gregwhitaker/ratpack-jwt-example)

An example of using [JSON Web tokens](https://jwt.io/introduction/) to authenticate with [Ratpack](http://www.ratpack.io).

This example starts a Ratpack application that hosts three endpoints: one secured with JWT as a url parameter, one secured with JWT as an Authorization header, and one that is not secured.

## Prerequisites

This example requires that you have installed the [Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files](http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html).

## Running the Example

1. Generate a `READ_WRITE` role JWT token by running the following Gradle command:

        $ ./gradlew generateReadWrite

    

2. Copy the generated token to the clipboard (It will look similar to the one below):

        eyJjdHkiOiJKV1QiLCJlbmMiOiJBMjU2R0NNIiwiYWxnIjoiZGlyIn0..rYmzSzVwurf_tJRk.VL_IzEqi9bihjSd44W8HCTIm2tfVqMTCAHklSxbsteO67mZ0nqxXfeo7h7D0tWy0Wk4Hg7jJngBu5Thd2m5S27xUlS9YsakkROmIOkdnsCs5j4mv5Qd9PgPRxSWAH2qC_K7fywpGlUoPojGO03MA0odbR9PPS4WpuBlealgKF2gAbcfADokyNy897AehcmEJ6ZRwzP--vKcCP59Z1CSqHEEgwLGgXOOQl7PAMgvhOHJwJJl5OvhHcQRg9vG89CegONXFypZNWDGv0LtcCjJ-H8_ZH-wWtkqjXyC2m9QipORc_Of-uLov-kJeuIRkT-M3DqwIyqofaO7MDv7xAuCtk_jpl0uN.UNev8gOwcbEhr9fJOCA5BQ

3. Start the example service by running the following Gradle command:

        $ ./gradlew run

4. Curl the JWT protected endpoint using the following command:

        $ curl -v http://localhost:5050/secure

        

5. Notice that you receive a `401 - Unauthorized` error.

6. Curl the JWT protected endpoint and supply the JWT token:

    If you wish to supply the JWT token as a URL parameter use the following command:

    

        $ curl -v http://localhost:5050/secure?token={your token}

        

    If you wish to supply the JWT token in the Authorization header use the following command:

    

        $ curl -v -H "Authorization: Bearer {your token}" http://localhost:5050/secureheader

7. Notice that you now have access to the secure resource and your user information.

        {

          "message": "This endpoint is protected by JWT",

          "user": {

            "displayName": "jdoe",

            "roles": [

              "READ_WRITE"

            ],

            "email": "john.doe@netifi.com"

          }

        }
