I'm trying to build a Python-based push notification process. Eventually, I'll host it on a Mac or on AWS, and send out push notifications through there. Here's my current working copy (I'll update it occasionally) in trying to build that python service.

adn-createStreamAndMonitor

import time
import json
import requests
from pprint import pprint

# Here's what I want running on the server. For now, I'm running it on my local machine.

# FIRST, WE NEED AN APP TOKEN
appTokenURL = 'https://account.app.net/oauth/access_token'
clientID = 'MY_CLIENT_ID'
clientSecret = 'MY_CLIENT_SECRET'
grantType = 'client_credentials'
appTokenRequestPayload = dict(client_id=clientID, client_secret=clientSecret, grant_type=grantType)

tokenResponseObject = requests.post(appTokenURL,appTokenRequestPayload)

tokenData = json.loads(tokenResponseObject.text)
appAccessToken = tokenData['access_token']
# pprint('Blixt app token is ' + appAccessToken)


# SECOND, WE NEED TO CREATE AN APP STREAM
ADN_HOSTNAME = 'https://alpha-api.app.net'
headerString = '?access_token='+appAccessToken
createStreamEndpoint = ADN_HOSTNAME + '/stream/0/streams'+headerString

objectTypes = ['post','star','user_follow','message']
streamObject = {'endpoint':createStreamEndpoint, 'object_types':objectTypes, 'type':'long_poll', 'key':'io.blixt.blixt-server'}
pprint(json.dumps(streamObject))
blixtStreamResponseObject = requests.post(createStreamEndpoint,json.dumps(streamObject))
 
blixtStreamData = json.loads(blixtStreamResponseObject.text)
pprint(blixtStreamData)

# Currently, here's what I see in Terminal when I run this:
# '{"endpoint": "https://alpha-api.app.net/stream/0/streams?access_token=MYACCESSTOKENWOULDGOHEREBUTNOTINTHISGIST", "type": "long_poll", "key": "io.blixt.blixt-server", "object_types": ["post", "star", "user_follow", "message"]}'
# {u'meta': {u'code': 400,
#            u'error_id': u'ce4c2ca1b0c2436399d1f7309b95c70d',
#            u'error_message': u'Bad Request: You must create streams with JSON'}}

# So - what am I doing wrong that I get a bad request?
