# Abfrage von Reisedaten der Deutschen Bahn aus der Auftragsnummer

Dieses Projekt implementiert einen kleinen JSON-Wrapper um die Abfrage der Ticketdaten auf <https://www.bahn.de/p/view/index.shtml>.


## Installation

```
virtualenv venv
source venv/bin/activate
pip install -r requirements
```


## Start

```
gunicorn app:app
```

Dies startet einen lokalen Server auf <http://127.0.0.1:8000>.


## Nutzung

Für eine sechsstellige-Auftragsnummer `TYFMQE` sieht können mit `http://127.0.0.1:8000/TYFMQE` die Reisedaten abgerufen werden. Diese sehen in etwa so aus:
