Decoding http response with gzip encoding in python

Here is the function to use:

import gzip
import StringIO
import zlib

def decode (page):
    encoding = page.info().get("Content-Encoding")    
    if encoding in ('gzip', 'x-gzip', 'deflate'):
        content = page.read()
        if encoding == 'deflate':
            data = StringIO.StringIO(zlib.decompress(content))
        else:
            data = gzip.GzipFile('', 'rb', 9, StringIO.StringIO(content))
        page = data.read()

    return page

Twitter oauth2 application only using python

Here is the first method using urllib library

import urllib
import base64
import httplib&lt;/code&gt;</pre>

CONSUMER_KEY = 'my_key'
CONSUMER_SECRET = 'my_secret'
encoded_CONSUMER_KEY = urllib.quote(CONSUMER_KEY)
encoded_CONSUMER_SECRET = urllib.quote(CONSUMER_SECRET)

concat_consumer_url = encoded_CONSUMER_KEY + ":" + encoded_CONSUMER_SECRET

host = 'api.twitter.com'
url = '/oauth2/token/'
params = urllib.urlencode({'grant_type' : 'client_credentials'})
req = httplib.HTTPSConnection(host)
req.putrequest("POST", url)
req.putheader("Host", host)
req.putheader("User-Agent", "My Twitter 1.1")
req.putheader("Authorization", "Basic %s" % base64.b64encode(concat_consumer_url))
req.putheader("Content-Type" ,"application/x-www-form-urlencoded;charset=UTF-8")
req.putheader("Content-Length", "29")
req.putheader("Accept-Encoding", "utf-8")

req.endheaders()
req.send(params)
resp = req.getresponse()

print resp.status, resp.reason
print resp.read()

This is the Second Method using pycurl

import sys # used for the storage class
import pycurl # used for curling
import base64 # used for encoding string
import urllib # used for enconding
import cStringIO # used for curl buffer grabbing
import json # used for decoding json token
import time # used for stuff to do with the rate limiting
from time import sleep # used for rate limiting
from time import gmtime, strftime # used for gathering time

def get_bearer_token(consumer_key,consumer_secret):
	# enconde consumer key
	consumer_key = urllib.quote(consumer_key)
	# encode consumer secret
	consumer_secret = urllib.quote(consumer_secret)
	# create bearer token
	bearer_token = consumer_key+':'+consumer_secret
	# base64 encode the token
	base64_encoded_bearer_token = base64.b64encode(bearer_token)
	# set headers
	headers = [
	"POST /oauth2/token HTTP/1.1",
	"Host: api.twitter.com",
	"User-Agent: shobhit Twitter Application-only OAuth App Python v.1",
	"Authorization: Basic "+base64_encoded_bearer_token+"",
	"Content-Type: application/x-www-form-urlencoded;charset=UTF-8",
	"Content-Length: 29"]
	token_url = "https://api.twitter.com/oauth2/token"
	buf = cStringIO.StringIO()
	access_token = ''
	pycurl_connect = pycurl.Curl()
	pycurl_connect.setopt(pycurl_connect.URL, token_url) # used to tell which url to go to
	pycurl_connect.setopt(pycurl_connect.WRITEFUNCTION, buf.write) # used for generating output
	pycurl_connect.setopt(pycurl_connect.HTTPHEADER, headers) # sends the customer headers above
	pycurl_connect.setopt(pycurl_connect.POSTFIELDS, 'grant_type=client_credentials')
        pycurl_connect.perform() # perform the curl
	access_token = buf.getvalue() # grab the data
	pycurl_connect.close() # stop the curl
	x = json.loads(access_token)
	bearer = x['access_token']
	return bearer
