Python 3 basic auth with pinnaclesports API - api

Question

i am trying to grab betting lines with python from pinnaclesports using their API http://www.pinnaclesports.com/api-xml/manual
which requires basic authentication (http://www.pinnaclesports.com/api-xml/manual#authentication):
Authentication
API use HTTP Basic access authentication . Always use HTTPS to access
the API. You need to send HTTP Request header like this:
Authorization: Basic
For example:
Authorization: Basic U03MyOT23YbzMDc6d3c3O1DQ1
import urllib.request, urllib.parse, urllib.error
import socket
import base64
url = 'https://api.pinnaclesports.com/v1//feed?sportid=12&leagueid=6164'
username = "abc"
password = "xyz"
base64 = "Basic: " + base64.b64encode('{}:{}'.format(username,password).encode('utf-8')).decode('ascii')
print (base64)
details = urllib.parse.urlencode({ 'Authorization' : base64 })
details = details.encode('UTF-8')
url = urllib.request.Request(url, details)
url.add_header("User-Agent","Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.29 Safari/525.13")
responseData = urllib.request.urlopen(url).read().decode('utf8', 'ignore')
print (responseData)
Unfortunately i get a http 500 error. Which from my point means either my authentication isn't working properly or their API is not working.
Thanks in advance

Answer 1

As it happens, I don't seem to use the Python version you use, so this has not been tested using your code, but there is an extraneous colon after "Basic" in your base64 string. In my own code, adding this colon after "Basic" indeed yields a http 500 error.
Edit: Code example using Python 2.7 and urllib2:
import urllib2
import base64
def get_leagues():
url = 'https://api.pinnaclesports.com/v1/leagues?sportid=33'
username = "myusername"
password = "mypassword"
b64str = "Basic " + base64.b64encode('{}:{}'.format(username,password).encode('utf-8')).decode('ascii')
headers = {'Content-length' : '0',
'Content-type' : 'application/xml',
'Authorization' : b64str}
req = urllib2.Request(url, headers=headers)
responseData = urllib2.urlopen(req).read()
ofn = 'api_leagues.txt'
with open(ofn, 'w') as ofile:
ofile.write(responseData)
