This is an assignment for an apprenticeship at Grinatom. Need to write a robot that keeps a counter and a server that controls the robot.
- The program should work and run under Windows.
- Before you start, you need to initialize the git repository so see how the project progressed.
- Need to write a web service backend on FastAPI that is able to start and stop the robot.
- The robot is a Python script that also needs to be written. It must run separately and independently (not inside a web service on FastAPI). Its job: to output numbers from 0 onwards to the console every second, adding one at a time until the script execution is interrupted. The robot should work asynchronously.
- The robot at startup must accept a command line parameter - from what number to start counting (by default - from zero). The web service on FastAPI should be able to pass this number.
Additional task (can be realized if you have enough time and energy):
- The program should store information about the time and duration of each run in a database (SQLite), as well as information about the date from which the countdown was started. FastAPI should have an additional endpoint to output this information.
Before start server, you should install virtual environment with dependencies.
After you have bent the project, in the project folder through the terminal, execute the commands:
python3 -m venv local_python_environment
source local_python_environment/bin/activate
pip install -r requirements.txt
To start server run python server/app.py or run follow commands in terminal
cd server
uvicorn app:app
To start the robot you need to use the following request:
POST "/start_robot/"
Description: the start value for start_number is automatically 0.
POST "/start_robot/{start value}"
Description: POST "/start_robot/13" will start from 13.
To stop robot:
POST "/stop_robot/"
Any other queries will return errors
Attention: If you try to start more robots than one, they will queue up and start working only when the process is finished.
