Introduction

untis4j is a rich java API for the webuntis timetable / schedule software and is inspired from the python webuntis api and another java webuntis api. It support almost all webuntis request and is easy to use. If a request method is missing, you can easily implement the method yourself with the Session.getCustomData(...) method.

Examples

To get an overview about all classes and methods, read the docs.

Note: For the Session.login(...) method a server and a school name is required. To gain these you have to go to webuntis.com, type in your school and choose it. Then you will be redirected to the untis login page. The url of this page is, for example https://example.webuntis.com/WebUntis/?school=myschool#/basic/main. The server is the beginning of the url https://example.webuntis.com and the school name is the parameter after the ?school=, in this case it is myschool

Simple timetable

public class Main {
    
    public static void main(String[] args) {
        try { 
            Session session = Session.login("your webuntis username", "your webuntis password", "https://example.webuntis.com", "myschool");  // create a new webuntis session

            // get the timetable and print every lesson
            Timetable timetable = session.getTimetableFromClassId(LocalDate.now(), LocalDate.now(), session.getInfos().getClassId());
            for (int i = 0; i < timetable.size(); i++) {
                System.out.println("Lesson " + (i+1) + ": " + timetable.get(i).getSubjects().toString());
            }

            // logout
            session.logout();
        } catch (LoginException e) {
            // this exception get thrown if something went wrong with Session.login
            System.out.println("Failed to login: " + e.getMessage());
        } catch (IOException e) {
            // if an error appears this get thrown
            e.printStackTrace();
        }
    }
}

Find / search a specific class

public class Main {
    
    public static void main(String[] args){
        try { 
            Session session = Session.login("your webuntis username", "your webuntis password", "https://example.webuntis.com", "myschool");  // creates a new webuntis session

            Classes classes = session.getClasses();

            // get a class by its id
            // findBy(...) methods only returns one result
            System.out.println(classes.findById(1234));

            // this prints all classes which contains 's' in their name.
            // searchBy(...) methods can return multiple results / matches
            for (Classes.ClassObject classObject : classes.searchByName("s")) {
                System.out.println(classObject);
            }

            // logout
            session.logout();
        } catch (LoginException e) {
            // this exception get thrown if something went wrong with Session.login
            System.out.println("Failed to login: " + e.getMessage());
        } catch (IOException e) {
            // if an error appears this get thrown
            e.printStackTrace();
        }
    }

}

Custom request

public class Main {

    public static void main(String[] args) {
        try { 
            Session session = Session.login("your webuntis username", "your webuntis password", "webuntis.grupet.at", "demo_inf");
            // creates a new webuntis session

            Response response = session.getCustomData("getAMethodThatIsNotImplemented");
            // requests the custom method
            if (response.isError()) {
                // you can easily check if the response contains an error
                return;
            } else {
                // get the response...
                JSONObject responseObject = response.getResponse();
                // ...and read it
                JSONObject result = responseObject.getJSONObject("result");

                System.out.println(result.toString());
            }

            // logout
            session.logout();
        } catch (LoginException e) {
            // this exception get thrown if something went wrong with Session.login
            System.out.println("Failed to login: " + e.getMessage());
        } catch (IOException e) {
            // if an error appears this get thrown
            e.printStackTrace();
        }
    }
}

Information

Caching

Caching allows to use saved request responses. The advantages of caching are the obviously faster answer when the same things are requested, that the server does not have to send as much data and in case of internet loss data can still be accessed. Caching is activated by default, but can use Session.useCache(...) to enable / disable it.
