Kong JWT test

  • Clone Kong/docker-kong repo fom Github: [email protected]:Kong/docker-kong.git
  • Pimp up docker-compose, as you can see below in docker-compose.yml
  • Run docker-compose: cd docker-kong/compose and docker-compose up

Here we are using ping to check the health of the core-data micro service (core-data operates on port 6543 by default). http://192.168.10.130:6543/api/v1/ping Kong listen on IP: 192.168.10.20, ports 8000 and 8001

Registrate service to Kong

$ curl -X POST --url http://192.168.10.20:8001/services/ \
-d "name=core-data" \
-d "url=http://192.168.10.130:6543" 

{"host":"192.168.10.130","created_at":1542662026,"connect_timeout":60000,"id":"a17d890c-b6d6-4157-ae88-3773aee894ed","protocol":"http","name":"core-data","read_timeout":60000,"port":6543,"path":null,"updated_at":1542662026,"retries":5,"write_timeout":60000}

Add route to service

$ curl -X POST  --url http://192.168.10.20:8001/services/core-data/routes  --data "paths[]=/core-data"

{"created_at":1542662379,"strip_path":true,"hosts":null,"preserve_host":false,"regex_priority":0,"updated_at":1542662379,"paths":["\/core-data"],"service":{"id":"e7e84380-3d4b-43fb-8910-86f38511af91"},"methods":null,"protocols":["http","https"],"id":"cbc5dce5-472a-4cc5-98f0-dcc9f64d66ad"}

Setting up JWT plugin to service

$ curl-X POST  --url http://192.168.10.20:8001/services/core-data/plugins -d "name=jwt"

{"created_at":1542662730000,"config":{"secret_is_base64":false,"key_claim_name":"iss","cookie_names":{},"maximum_expiration":0,"anonymous":"","run_on_preflight":true,"uri_param_names":["jwt"]},"id":"f66ac080-e532-4fe4-bcad-7ed5785f2c3e","enabled":true,"service_id":"e7e84380-3d4b-43fb-8910-86f38511af91","name":"jwt"}

$ curl -i -X GET --url http://192.168.10.20:8000/core-data/api/v1/ping

HTTP/1.1 401 Unauthorized
Date: Mon, 19 Nov 2018 21:25:36 GMT

Create customer and JWT token

$ curl -X POST  --url http://192.168.10.20:8001/consumers -d "username=felegy"

{"custom_id":null,"created_at":1542662794,"username":"felegy","id":"3ddfab05-a0b6-42f3-b91f-7065795db13d"}

$ curl -X POST  --url http://192.168.10.20:8001/consumers/felegy/jwt -H "Content-Type: application/x-www-form-urlencoded"

{"created_at":1542662959000,"id":"4b2d8af5-7d6a-49dc-92ab-bbccdbb36193","algorithm":"HS256","key":"mxjwd8YcXs44xpDvUCiNUtD7FXqehsj9","secret":"wTMoShWJ2t0G7ku8suL0I4h78soWiECv","consumer_id":"3ddfab05-a0b6-42f3-b91f-7065795db13d"}

jwt.io helps to create signed and encrypted token:

HEADER:

{
  "alg": "HS256",
  "typ": "JWT"
}

PAYLOAD:

{
  "iss": "mxjwd8YcXs44xpDvUCiNUtD7FXqehsj9",
  "username": "felegy"
}

VERIFY SIGNATURE:

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  
wTMoShWJ2t0G7ku8suL0I4h78soWiECv

)

and as you can see (on a left side at jwt.io)

Using token to authorize the request to core-data access:

$ curl -i -X GET --url http://192.168.10.20:8000/core-data/api/v1/ping -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJteGp3ZDhZY1hzNDR4 cER2VUNpTlV0RDdGWHFlaHNqOSIsInVzZXJuYW1lIjoiZmVsZWd5In0.vrdQE2s7f7sQPZ20BkQn_9qQl5EW0cqMr1Kl7pU4eMw"
