Task : Extract blood glucose data/log using ManageBGL REST API
URL Structure:
- To obtain authentication token for future requests;
https://www.ManageBGL.com/api/1.0/login?email=email&password=password
- To extract data/log for specified range;
https://www.ManageBGL.com/api/1.0/extract?token=token&start_date=start_date&end_date=end_date
Application:
First, import required modules:
from datetime import datetime, timedelta
from xmltodict import parse
import urllib2, urllibDefine the method:
BGL_URL = "https://www.managebgl.com/api/1.0"
def extract_bloodglucose_data():
# obtain the token
token_response = urllib2.urlopen("%s/login.xml?email=%s&password=%s" % (BGL_URL, email, password))
token_parse = parse(token_response)
# check if it returns the token
if token_parse.has_key('response') and token_parse['response']['result'] == '1':
token = token_parse['response']['token']
Extracting logs:
# define parameters
yesterday = str(datetime.now().date() - timedelta(1))
param = (
BGL_URL,
token,
yesterday + urllib.quote_plus(" 00:00:00")
yesterday + urllib.quote_plus(" 23:59:59")
)
# using XML format
extract_response = urllib2.urlopen("%s/extract.xml?token=%s&start_date=%s&end_date=%s" % (param))
extract_parse = parse(extract_response)
# check if it returns logs
if extract_parse.has_key('response') and extract_parse['response']['rows'] != '0':
for log in extract_parse['response']['logs']:
# Log type for the data needed;
# Insulin = 2
# hbalc = 21
# c_peptide = 42
# fasting_plasma_glucose_test = 43
# oral_glucose_tolerance_test = 44
# random_plasma_glucose_test = 45
# triglyceride = 46
#
# Assigning the values:
if log['logtype_id'] == '2':
insulin = log['value']
elif log['logtype_id'] == '46':
triglyceride = log['value']
....
Cheers! :)
