Overview

• This project is about Flask based API services. Integration with Flask-restplus, Flask-Cors, Flask-Testing, Flask-SQLalchemy,and Flask-OAuth extensions.

Extension:

• Restful: Flask-restplus

• SQL ORM: Flask-SQLalchemy

• Testing: Flask-Testing

• OAuth: Flask-OAuth

Installation

Install with pip:

$ pip install -r requirements.txt

Objective: To develop RESTful APIs using that can be utilized by mobile and web applications. The applications will satisfy the following user stories:

● User should be able to login or sign up using his phone number (no OTP or verification code required). ● User can calculate simple algebraic calculations of two variables viz. x and y, for eg. x + y.

To run the project: Go to project directory and then run:

1. python3 run_flasked_app.py

   OR

2. gunicorn run_flasked_app:app_wsgi --preload -b 0.0.0.0:8000

Create new docker image for the project

1. $ docker build -t <container_image_name> <destination_dir> for e.g. docker built -t truckbook-docker-image ./

2. $ docker images # To check running docker images

3. $ docker run -rm -it -d -p <port_of_choice>:5011 <container_image_name>

Database: Postgres (local)

Descriptions of APIs and endpoints:

1. Sign-up with phone number and password on sign-up page 0.0.0.0:8000/signup
2. GET Method to fetch result GET 0.0.0.0:8000/
3. POST Method to calculate algebraic calculations (viz, add, subtract, multiply, divide) POST 0.0.0.0:8000/calculate with JSON request body as
   { "operation": "add", "x": 20, "y": 30 }
4. Test cases can be run : python -m unittest /unit_testing/test_cal.py
