Magically generate Deutsche Bahn ticket URLs. Given a journey
queried with hafas-client@5
, it tries to generate a matching ticket link in the Deutsche Bahn shop. Caveats:
- Uses a lot of scraping, as there is no (publicly accessible) machine-readable interface to the ticket system. This makes
generate-db-shop-urls
brittle. - Because of how (bad) the shop works, the generated links will only be valid with a browser session that hasn't recently been used to search for a connection, or one without any cookies/session.
npm install generate-db-shop-urls
generate-db-shop-urls
expects one (outbound) or two (outbound & returning) journey
s queried with hafas-client@5
as input.
const createHafas = require('db-hafas')
const generateTicketLink = require('generate-db-shop-urls')
const berlin = '8096003'
const hamburg = '8000157'
const hafas = createHafas('my-awesome-program')
const outbound = await hafas.journeys(berlin, hamburg, {
departure: new Date('2017-05-18T05:00+0200'),
results: 1,
})
const returning = await hafas.journeys(hamburg, berlin, {
departure: new Date('2017-05-19T12:00+0200'),
results: 1,
})
const link = await generateTicketLink(outbound.journeys[0], {
returning: returning.journeys[0],
})
console.log(link)
async (outbound, opt = {}) => {}
opt
overrides the default options which look as follows:
{
// type of BahnCard, '0' = no bahncard
// see https://gist.github.com/juliuste/202bb04f450a79f8fa12a2ec3abcd72d
bahncard: '0',
class: '2', // '1' or '2'
age: 40, // age of the traveller
returning: null // returning journey to match (optional)
}
