Pytest API Post call thrown errors

[pyseeker]

I am performing the API Testing and using the pytest framework. Test is failing all the time with 401 error. Couldn't figure out what was the issue and where am I going wrong. When I manually test it using Postman, it is working.

Here is the code :

import requests
import json,jsonpath
import urllib3
import constants
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

# variables
dumpFile = "somepath"
url = "someUrl"
headers = {'Authorization' : constants.consts['siteToken']}
#siteToken = 'Bearer jwt token'

# read json input file
input_file = open("json file path", 'r')
json_input = input_file.read()
request_json = json.loads(json_input)

# make POST request with JSON Input Body
r = requests.post(url, request_json)
print(r.content)

# Verification of the response
def test_result():
    assert r.status_code == 200

# fetch header from response
print(r.headers.get("Date"))

# parse response to JSON Format
response_json = json.loads(r.text)

# validate response using Json Path
name = jsonpath.jsonpath(response_json, 'name')
print(name)

Error is as below :
