An asynchronus way for working with the vtop website. Inspired from the project VITASK from our peers at VIT-Chennai I tried an asynchronous way of working with the vtop website. VITASK
Brief Overview:
- We mainly uses aiohttp for requests i.e working with the website.
- Pandas for parsing the data. And BeautifulSoup too.
- The project is mainly wirtten in python 3.9.
- The project is present in the src directory.
- See the vtop_handler_examples.py for examples on how to use the vtop_handler package.
- Download all the dependencies
pip install -r requirements.in - Run the shell command
sh start.sh
- Clone the repo
git clone https://github.com/Sarath191181208/VTOP_API- Install the requirements
pip install -r requirements.txt- To run the server To run the app go to src/ folder and then run
python app.pyAll the characters are saved in vtop_handler/bitmaps.json. The captcha is solved by comparing the bitmaps of the captcha with the bitmaps of the characters. This gives us an accuracy score of letters for every letter in the captcha ,we pick the max letter which has the highest accuracy score. see in vtop_handler/session_generator.py it has _solve_captcha function for how it is implemented.
