How do I parse a JSON response from Python Requests?

Question

I am trying to parse a response.text that I get when I make a request using the Python Requests library. For example:

def check_user(s         


        

Answer 1

    import json

    def check_user(self):
        method = 'POST'
        url = 'http://localhost:5000/login'
        ck = cookielib.CookieJar()
        response = requests.request(method,url,data='username=test1&passwd=pass1', cookies=ck)

        #this line converts the response to a python dict which can then be parsed easily
        response_native = json.loads(response.text)

        return self.response_native.get('result') == 'success'

Answer 2

Put in the return of your method like this:

return self.response.json()

If you wanna looking for more details, click this following link: https://www.w3schools.com/python/ref_requests_response.asp

and search for json() method.

Here is an code example:

import requests
url = 'https://www.w3schools.com/python/demopage.js'
x = requests.get(url)
print(x.json())

Answer 3

The manual suggests: if self.response.status_code == requests.codes.ok:

If that doesn't work:

if json.loads(self.response.text)['result'] == 'success':
   whatever()

Answer 4

If the response is in json you could do something like (python3):

import json
import requests as reqs

# Make the HTTP request.
response = reqs.get('http://demo.ckan.org/api/3/action/group_list')

# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)

for i in response_dict:
    print("key: ", i, "val: ", response_dict[i])

---

To see everything in the response you can use .__dict__:

print(response.__dict__)

Answer 5

Since the output, response, appears to be a dictionary, you should be able to do

result = self.response.json().get('result')
print(result)

and have it print

'success'

Answer 6

In some cases, maybe the response would be as expected. So It'd be great if we can built a mechanism to catch and log the exception.

import requests
import sys

url = "https://stackoverflow.com/questions/26106702/how-do-i-parse-a-json-response-from-python-requests"
response = requests.get(url)

try:
    json_data = response.json()
except ValueError as exc:
    print(f"Exception: {exc}")

    # to find out why you have got this exception, you can see the response content and header
    print(str(response.content))
    print(str(response.headers))
    print(sys.exc_info())

else:
    if json_data.get('result') == "success":
        # do whatever you want
        pass
