noops-challenge / fizzbot

Fizzbot has questions for you... so many questions. A FizzBuzz API for you to play with.

Fizzbot

Dear candidate.

Thank you for your interest.

Here at Noops Headquarters we receive a number of applications for positions in our world-class software development organization.

Unfortunately, we are very busy cooking up new challenges, so we cannot personally repond to each application.

API

Get started at https://api.noopschallenge.com/fizzbot — but do it quickly!

We don't have time for slowpokes around here, and we will grade you on how fast you can solve this challenge.

Fizzbot will give you a series of questions. Solve each one by GETting the question from the provided url and then POSTing the answer back to the same url.

Fizzbot will give you a 200 response if you are correct, and a 400 response if you need to try again. Learn more about HTTP status codes.

Answering a question correctly will give you the path to the next question. When you answer all of the questions correctly, Fizzbot will grade your performance. If you're not happy with your grade, you can always try again to get a better score.

Read the API documentation for more information.

Starters

Get started with Python or Ruby using the included scripts, or start from scratch.

Python

Here are two interactive interactive starter kits, made for Python 3 and Python 2.

Learn how to install Python.

Ruby

This example shows how you might write a bot that can solve the fizzbot challenge automatically.

Check out the Ruby script and try to beat Fizzbot at its own game.

Favorite Programming Language incorrect answer

The following request gives me an error:
curl -X POST -d {"answer":"python"} https://api.noopschallenge.com/fizzbot/questions/1

{"message":"Please provide an answer that is a string.","result":"incorrect"}

But I have followed the example response:
"exampleResponse":{"answer":"COBOL"}

What am I missing here?

No access through browser request

The noops API is blocking POST requests made from javascript through the browser. POST request seem to be allowed but the mandatory pre-flight OPTIONS request is not allowed by the server. The following headers are returned by the API:

access-control-allow-methods: GET,HEAD,PUT,PATCH,POST,DELETE
access-control-allow-origin: *

I am making the request as follows:

axios.post(url, options, {
        headers: {
          'Content-type': 'application/application/json',
        },
      }).then(response => {
        console.log(response)
      })

Is there any way to include OPTIONS requests in the allowed methods?
