### imports (Pakete evtl. mit "sudo pip install --upgrade requests" installieren!)

import requests

import hmac

import base64

import hashlib

import json

from requests.auth import AuthBase



### Config 

requestType = "checkName" # M�gliche Typen siehe 1.7 Funktions�bersicht im Handbuch

username = "" # HVV Zugang

password = "" # HVV Zugang

url = "http://api-test.geofox.de/gti/public/"

requestUrl = url + requestType



### Auth erstellen

class HVVAuth(AuthBase):

    def __init__(self, payloadFunc):

        # setup any auth-related data here

        print(json.dumps(payloadFunc))

        self.sig = base64.b64encode(hmac.new(password.encode("UTF-8"), json.dumps(payloadFunc).encode('UTF-8'), hashlib.sha1).digest())

        print(hmac.new(password.encode("UTF-8"), json.dumps(payloadFunc).encode('UTF-8'), hashlib.sha1).digest());

        print(self.sig);

    def __call__(self, r):

        # modify and return the request

        r.headers['geofox-auth-signature'] = self.sig

        r.headers['geofox-auth-user'] = username

        return r



### Request an die API stellen (siehe Handbuch)

payload = {

    "coordinateType": "EPSG_4326",

    "maxList": '1',

    "theName": {

      "name": "Informatikum",

      "type": "STATION"

    }

}

print(payload)

### tats�chlichen Request abschicken

req = requests.post(requestUrl, json=payload, auth=HVVAuth(payload))



### Consolen Ausgabe

print 'HTTP Headers:' # debug only

print req.headers

print 'HTTP Code: ' + str(req.status_code) # 200 = OK, 401 = Unauthorisiert etc.
