Test with curl

Curl is a powerful HTTP client that we can use to test our server.

1. First, we can check that the server responds correctly:

curl http://localhost:8000

2. If we try to get a prohibited content we get an error:

curl http://localhost:8000/private -b cookies.txt

3. Now, we are going to log in:

curl -H "Content-Type: application/json" -d '{"username": "user", "password": "pass"}' http://localhost:8000/login -c cookies.txt

4. Now, we can access the private content:

curl http://localhost:8000/private -b cookies.txt

5. After that, we are going to log out:

curl -X POST http://localhost:8000/logout -c cookies.txt

6. And we can see that the private content becomes inaccessible again:

curl http://localhost:8000/private -b cookies.txt
