CURL Python JSON Request

If you are working with APIs, chances are you will need to send requests to get data in JSON format. One way to do this is by using CURL in Python. Here are some ways to accomplish this task:

Using the requests library

The requests library is a popular library that simplifies making HTTP requests in Python. Here is an example of using requests to make a CURL request to an API that returns JSON data:


import requests

url = 'https://example.com/api/data'
headers = {'Content-Type': 'application/json'}
payload = {'key': 'value'}

response = requests.post(url, headers=headers, json=payload)

if response.status_code == 200:
    data = response.json()
else:
    print('Error: Could not retrieve data')

In this example, we are sending a POST request to the API with a JSON payload. We are also setting the Content-Type header to indicate that we are sending JSON data. The response is then parsed into a JSON object for further processing.

Using the subprocess module

The subprocess module allows you to spawn new processes and execute commands in the shell. Here is an example of using subprocess to make a CURL request and parse the JSON response:


import subprocess
import json

url = 'https://example.com/api/data'
cmd = ['curl', '-X', 'POST', '-H', 'Content-Type: application/json', '-d', '{"key": "value"}', url]

output = subprocess.check_output(cmd)
data = json.loads(output.decode('utf-8'))

In this example, we are using the subprocess module to execute the CURL command and capture the output. We then use the json module to parse the output into a JSON object.

Using the pycurl library

The pycurl library is a Python interface to the CURL library. Here is an example of using pycurl to make a CURL request and parse the JSON response:


import pycurl
import json

url = 'https://example.com/api/data'
headers = {'Content-Type': 'application/json'}
payload = '{"key": "value"}'

curl = pycurl.Curl()
curl.setopt(pycurl.URL, url)
curl.setopt(pycurl.HTTPHEADER, [f'{k}: {v}' for k, v in headers.items()])
curl.setopt(pycurl.POSTFIELDS, payload)

response = curl.perform_rs()
data = json.loads(response.decode('utf-8'))

In this example, we are using the pycurl library to make the CURL request and capture the response. We then use the json module to parse the response into a JSON object.
