dsbuntis #
This package allows you to crawl DSB's "Mobile API" and parse Untis's HTML.
Usage #
For a basic example on how to get your substitutions, please refer to the example.
Lower-level APIs (Session
) #
getAllSubs
only accounts for the most basic usage. For a more customizable experience, you'll want
to use the Session
API.
Session
s are created in two ways: Logging in or using an existing token.
To log in, you call Session.login
:
final session = await Session.login('187801', 'public');
To use an existing token, you previously (6.1) used Session.fromToken
. Now, the Session
constructor allows for passing them:
final session = Session('13ccccbb-e6a8-466a-addc-00bba830c6cf');
Then you can get the JSON with timetable information:
final ttJson = await session.getTimetableJson();
And download and parse the plans:
final downloadingPlans = session.downloadPlans(ttJson);
final plans = await session.parsePlans(downloadingPlans);
Caching and best practices #
A very important feature in dsbuntis
from the beginning has been good caching. For documentation on
how to set it up for the actual requests, please refer to the schttp
documentation, as it is the
HTTP backend of dsbuntis
. From version 6 on, however, you can aditionally cache Session
s. AFAIK
the login of DSBMobile is idempotent (as indicated by it being a GET
request) and always returns the
same token. (don't assume this is true yet) If it is, you can cache the Session
's token
forever.
If it isn't, you can still cache the Session
object.
