The HashiCups menu and orders

Get the available coffees:

$ curl -v localhost:19090/coffees | jq

The following api call requires authorization.

First, sign-in with previously created account:

$ curl -X POST localhost:19090/signin -d '{"username":"education", "password":"test123"}'

Then, export the returned JWT token to HASHICUPS_TOKEN:

$ export HASHICUPS_TOKEN=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MTU5ODcxNzgsInVzZXJfaWQiOjEsInVzZXJuYW1lIjoiZWR1Y2F0aW9uIn0.VJQXoxror-_ZUoNHtsG6GJ-bJCOvjU5kMZtXhSzBtP0

With that, you can perform authorized calls.

Get the ingredients for a coffee:

$ curl -X GET  -H "Authorization: ${HASHICUPS_TOKEN}" localhost:19090/coffees/1/ingredients | jq

Get the created orders:

$ curl -X GET  -H "Authorization: ${HASHICUPS_TOKEN}" localhost:19090/orders | jq
