Webservice calculating the first n Fibonacci numbers

Fib_Web

Provides a web service to calculate the first n Fibonacci numbers, using Python and Flask.

Prerequisites

Ensure your system has at least Python 2.7 installed. This was developed on a machine running 2.7.10. Assuming you have pip installed, pip install -r requirements.txt will install Flask 0.12.2. If you don't want your currently installed Python packages touched, consider setting up a virtualenv.

Running and Using

From the directory containing fib.py, run python fib.py &. This will start the service on your local machine, running on port 5000 in the background. To hit the endpoint, run curl -i localhost:5000/fib/<some positive integer>.

Integers less than 1, or any non integer values will return an error.

As an example, curl -i localhost:5000/fib/5 will return

$ curl -i localhost:5000/fib/5
127.0.0.1 - - [21/Dec/2017 21:54:07] "GET /fib/5 HTTP/1.1" 200 -
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 60
Server: Werkzeug/0.13 Python/2.7.10

{
  "result": [
    0,
    1,
    1,
    2,
    3
  ]
}

Remember, the process is running in your background, so make sure to bring it foward and kill it when you're finished.

Tests

To run the tests, run

python fib_tests.py

Note that fib_test.py must be in the same directory as fib.py
