Python example of using API

The following is an example Python program that illustrates use of the API.

Python example

You can copy the following code to a file, and run it where Python is installed on your machine:

python <filename.py>

You will need to fill in your specific environment information in this python file, such as Metric Insights URl, and API credentials

#!/opt/mi/.python/bin/python


import requests
import json


url = “<your metric insights URL>/api/get_token/”


values = {
  “application_id”: “<your application ID>“,
  “application_key”: “<your application key>“,
  “user”: “<username>”
}
headers = {“Accept” : “application/json”}


def httpRequestToAPI():
  data = json.dumps(values)
  print ‘Body: ’ + data
  r = requests.post(url,data=values,headers=headers)
  response = (r.text)
  return json.loads(response)


response = httpRequestToAPI()
print response
print ‘Token for use: ’ + response[“token”]
print ‘Expiration : ’ + response[“expires”]
   try:
      response = urllib2.urlopen(req)
   except urllib2.URLError as e:
       if hasattr(e, 'reason'):
           print 'We failed to reach a server.'
           print 'Reason: ', e.reason
       elif hasattr(e, 'code'):
           print 'The server couldn\'t fulfill the request.'
           print 'Error code: ', e.code
   else:
       # everything is fine


# return the response data
       result = response.read()
       return result
