How can I use python to execute a curl command?

+1 vote

I want to execute a curl command in python.

Usually, I just need to enter the command in terminal and press return key. However, I don't know how it works in python.

The command shows below:

curl -d @request.json --header "Content-Type: application/json"

There is a request.json file to be sent to get response.

I searched a lot and got confused. I tried to write a piece of code, although I could not fully understand. It didn't work.

import pycurl
import StringIO

response = StringIO.StringIO()
c = pycurl.Curl()
c.setopt(c.URL, '')
c.setopt(c.WRITEFUNCTION, response.write)
c.setopt(c.HTTPHEADER, ['Content-Type: application/json','Accept-Charset: UTF-8'])
c.setopt(c.POSTFIELDS, '@request.json')
print response.getvalue()

The error message is 'Parse Error'.Can anyone tell me how to fix it? or how to get response from the sever correctly?

For sake of simplicity, maybe you should consider using the standard library Requests.

An example with json response content would be something like:

import requests
r = requests.get('')

If you look for further information, in the Quickstart section, they have lots of working examples.


For your specific curl translation:

import requests
url = ''
payload = open("request.json")
headers = {'content-type': 'application/json', 'Accept-Charset': 'UTF-8'}
r =, data=payload, headers=headers)
