Scrapers for Professor Ratings and Reviews

Scrapers should all extend the WebScraper class which supports Object based output as well as JSON based output. These methods have a couple of thrown exceptions. NoResultsException will be thrown if the query didn't find any professors, and IOException will be thrown from network troubles.

Usage

You can download the code and builder the jar using the maven jar, but a simpler method is to use jitpack.io to include this repo as a dependency for your project.

ratemyprofessors.com

Use the RateMyProfessorWebScaper to scrape for results from rmp. Note the school formatting is very specific for rmp so you must use a constant from the School enum.

import edu.cpp.hci.scrapers.rmp.RateMyProfessorWebScaper;
import edu.cpp.hci.scrapers.rmp.dto.professor.impl.RateMyProfessorProfessor;
import edu.cpp.hci.scrapers.constants.School;
import edu.cpp.hci.scrapers.exceptions.NoResultsException;

import java.util.List;

public class Example {
    public static void main(String[] args) {
        RateMyProfessorWebScaper scrapper = new RateMyProfessorWebScaper("Yu Sun", School.CAL_POLY_POMONA);
        
        try {
            List<RateMyProfessorProfessorDTO> objectResult = scrapper.getData();
            String jsonResult = scrapper.getJson();
            System.out.println(jsonResult);
        } catch (IOException | NoResultsException e) {
            e.printStackTrace();
        }
    }
}
