APT Spring 2016: Assignment 1

Assignment:

We will be working on simple web project. Your task is to write a small web app that will fetch currency data from http://public.mig.kz/ and return in JSON format.

Setup:

• Create GitHub account.
• Save ssh key to GitHub https://github.com/settings/ssh:
  • if you do not have ~/.ssh/id_rsa.pub file, generate ssh key using ssh-keygen
  • cat ~/.ssh/id_rsa.pub
• Fork the https://github.com/giAtSDU/apt_spring_2016_hw1 repository
• Create virtual environment using pyvenv-3 venv
• If pip is not available by default, install it using these instructions https://pip.pypa.io/en/stable/installing/#installing-with-get-pip-py
• Activate your environment and install dependencies using pip pip install bottle requests beautifulsoup4
• Install git if it is not available on your linux maching: sudo apt-get install git

Tasks:

• Clone your forked repository to your local machine
• Run the server: python server.py
• Make sure that it works: goto http://localhost:5000; It should return dummy static data {"eur": 415, "rub": 4.82, "usd": 378}.
• Open the server.py file and see its contents.
• Change index method so that it will fetch real data from http://public.mig.kz site.
• You can see an example that fetches forks counter from this github repository. Run the server using python server.py and open http://localhost:5000/forks in your browser to test it.
• Use git commit to commit your change. Use a meaningful message like "."
• Use git push to send your change to your forked repository.
• Look online to see if your change has been pushed.
• Once you have finished upload the link of your forked repository to google classroom.

For those who wants more:

• Deploy your application to heroku
• Create an account on heroku.com
• See the tutorial https://devcenter.heroku.com/articles/getting-started-with-python-o
• Download the heroku toolbelt
• Create heroku application using heroku create. Run it inside the project folder. Heroku toolbelt will crate a remote in your git project. See git remote -v
• Deploy the project using git push heroku master
• Open an url that heroku generated for you
