Python Code For Data Extraction using OAuth API Client

[Vaibhav Vir.Singh]

Team,

With recent release (4.5) we see "API Client" through which we can pull metric data via POST API.

Even though we have documentation available at https://docs.appdynamics.com/display/PRO45/API+Clients

But I have not been able to execute it successully, so thought to check with you.

In below code, we have API Client named 'test21' and Account i am taking by default that is customer1.

Appreciate your help. 

geturl = 'https://'+ControllerPort+'/controller/api/oauth/access_token'
client_secret = '<<Secret_Copied>>'
data = {'grant_type': 'client_credentials','Content-Type': 'application/vnd.appd.cntrl+protobuf;v=1'}
access_token_response = requests.post(geturl, data=data, verify=False, allow_redirects=False, auth=('test21@customer1', client_secret))
print(access_token_response.text)

Any thoughts and help in this?

Just realized this thread i raised did not have any solution marked.

I accomplished so sharing for broader community. 

replace 'token' with big token string without quotes in the headers.

################

import requests

headers = {

    'Authorization': 'Bearer token',

}

# Sample Query to fetch all applications

response = requests.get('https://<<CONTROLLERHOST>>:8181/controller/rest/applications', headers=headers, verify=False)

print(response.text) # OR response.content

################

Either you use Token directly like above, OR you can get token generated from secret of API Client like below: 

curl -k -X POST -H "Content-Type: application/vnd.appd.cntrl+protobuf;v=1" "https://<<CONTROLLER:8181/controller/api/oauth/access_token " -d “grant_type=client_credentials&client_id=XYZ@customer1&client_secret=4c45*****801”

Hi 

To generate temporary access token using python, you can use request library of python .

  generate_token_url="https://<Controller URL>/controller/api/oauth/access_token"

  payload = {

    "grant_type":"client_credentials",

    "client_id":"Client_Id@ControllerName",

    "client_secret":"fe************************rf"

  }

  token_headers = { "Content-Type": "application/vnd.appd.cntrl+protobuf;v=1" }

  generate_token_response = requests.request("POST", generate_token_url, headers=token_headers, data=payload).json()

print(generate_token_response["access_token"])

you just need to change client_id and client_secret in payload
