Difficulty in passing JSON in Python

Question

I'm unable to parse JSON . My JSON snippet returned from requests.post response :-

{'result': {'parent': '', 'reason': '', 'made_sla': 'true', 'backout_plan': '', 'watch_list': '', 'upon_reject': 'cancel', 'sys_updated_on': '2018-08-22 11:16:09', 'type': 'Comprehensive', 'conflict_status': 'Not Run', 'approval_history': '', 'number': 'CHG0030006', 'test_plan': '', 'cab_delegate': '', 'sys_updated_by': 'admin', 'opened_by': {'link': 'https://dev65345.service-now.com/api/now/table/sys_user/6816f79cc0a8016401c5a33be04be441', 'value': '6816f79cc0a8016401c5a33be04be441'}, 'user_input': '', 'requested_by_date': '', 'sys_created_on': '2018-08-22 11:16:09', 'sys_domain': {'link': 'https://dev65345.service-now.com/api/now/table/sys_user_group/global', 'value': 'global'}, 'state': '-5', 'sys_created_by': 'admin', 'knowledge': 'false', 'order': '', 'phase': 'requested', 'closed_at': '', 'cmdb_ci': '', 'delivery_plan': '', 'impact': '3', 'active': 'true', 'review_comments': '', 'work_notes_list': '', 'business_service': '', 'priority': '4', 'sys_domain_path': '/', 'time_worked': '', 'cab_recommendation': '', 'expected_start': '', 'production_system': 'false', 'opened_at': '2018-08-22 11:16:09', 'review_date': '', 'business_duration': '', 'group_list': '', 'requested_by': {'link': 'https://dev6345.service-now.com/api/now/table/sys_user/user1', 'value': 'user1'}, 'work_end': '', 'change_plan': '', 'phase_state': 'open', 'approval_set': '', 'cab_date': '', 'work_notes': '', 'implementation_plan': '', 'end_date': '', 'short_description': '', 'close_code': '', 'correlation_display': '', 'delivery_task': '', 'work_start': '', 'assignment_group': {'link': 'https://dev65345.service-now.com/api/now/table/sys_user_group/testgroup', 'value': 'testgroup'}, 'additional_assignee_list': '', 'outside_maintenance_schedule': 'false', 'description': '', 'on_hold_reason': '', 'calendar_duration': '', 'std_change_producer_version': '', 'close_notes': '', 'sys_class_name': 'change_request', 'closed_by': '', 'follow_up': '', 'sys_id': '436eda82db4023008e357a61399619ee', 'contact_type': '', 'cab_required': 'false', 'urgency': '3', 'scope': '3', 'company': '', 'justification': '', 'reassignment_count': '0', 'review_status': '', 'activity_due': '', 'assigned_to': '', 'start_date': '', 'comments': '', 'approval': 'requested', 'sla_due': '', 'comments_and_work_notes': '', 'due_date': '', 'sys_mod_count': '0', 'on_hold': 'false', 'sys_tags': '', 'conflict_last_run': '', 'escalation': '0', 'upon_approval': 'proceed', 'correlation_id': '', 'location': '', 'risk': '3', 'category': 'Other', 'risk_impact_analysis': ''}}

I searched on the net. It is showing as as it is single quotes it's not parsing.

So I tried to convert the single quotes into double quotes.

with open ('output.json','r') as handle:
  handle=open('output.json')
str="123"
str=handle.stringify() #also with .str()
str = str.replace("\'", "\"")
jsonobj=json.load(json.dumps(handle))

But it shows me No attribute stringify or str as it is an json object and these are string object function. So, can you please help me with what is the correct way of parsing the json object with single quotes in a file.

The code:-

import requests
import json
from pprint import pprint

print("hello world")

url="********"

user="****"
password="*****"
headers={"Content-Type":"application/xml","Accept":"application/json"}

#response=requests.get(url,auth=(user,password),headers=headers)
response = requests.post(url, auth=(user, password), headers=headers ,data="******in xml****")

print(response.status_code)
print(response.json())

jsonobj=json.load(json.dumps(response.json()))
pprint(jsonobj)

Answer 1

What you receive from requests.post is not JSON, it's a dictionary.

One that can be encoded in JSON, via json.dumps(result) .

JSON is a text format to represent objects (the "ON" means "object notation"). You can convert a dictionary (or list or scalar) into a JSON-encoded string, or the other way around.

What requests.post does is taking the JSON response and already parsing it (with json.loads ), so you don't have to think about JSON at all.

Answer 2

You haven't shown the code where you get the data from the post. However, you are almost certainly doing something like this:

response = requests.post('...')
data = response.json()

Here data is already parsed from JSON to a Python dict; that is what the requests json method does. There is no need to parse it again.

If you need raw JSON rather than Python data, then don't call the json method. Get the data direct from the response:

data = response.content

Now data will be a string containing JSON.
