TODO - WEBSERVICE - ACTIX

Introduction

This is a simple Todo Rest service.

The application contains the basic CRUD elements, and write in a Postgres database provided in a Docker container. For the SQL instructions the POC uses an Rust implementation off MyBatis (Experimental). The Rest entry points are secured with KeyCloak and exchanges a JWT Token.

Running

Starting the Docker Compose file that includes a Postgres Database with 2 Schema’s:

• Schema Todo (Application)

• Schema KeyCloak (KeyCloak Application)

docker compose start

compile the application:

cargo build

run the application:

cargo run

Testing

For testing you can use Postman or like I prefer from IntelliJ the http files, see folder http. Some samples:

Retrieving an JWT Token

POST http://127.0.0.1:8888/realms/learn-rust-realm/protocol/openid-connect/token
Content-Type: application/x-www-form-urlencoded

client_id=learn-rust-client&username=student&password=password&grant_type=password

Retrieving the list of Todo’s

GET http://127.0.0.1:8080/api/todo
Authorization: Bearer {{token}}
Accept: application/json

Adding a Todo

POST http://127.0.0.1:8080/api/todo
Authorization: Bearer {{token}}
Content-Type: application/json

{
  "owner": "ME",
  "name": "ME",
  "description": "Learn Rust",
  "status": "OPEN"
}
