Put request working in curl, but not in Python

Question

I am trying to make a 'put' method with curl everything is working fine and I got the JSON back:

curl -X PUT -d '[{"foo":"more_foo"}]' http://ip:6001/whatever?api_key=whatever

But for some reason when using the python requests module as follow:

import requests
url = 'http://ip:6001/whatever?api_key=whatever'

a = requests.put(url, data={"foo":"more_foo"})

print(a.text)
print(a.status_code)

I get the following error:

500 Internal Server Error
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

NB: The server is up and running.

The data structures are different between your examples. Also note you can pass URL query parameters differently in `requests`, rather than in the URL string: http://docs.python-requests.org/en/master/user/quickstart/#passing-parameters-in-urls. — jonrsharpe, Dec 21 '17 at 14:11
yeah, i know about the data structure, but requests fails if i put them like the exact one in curl. thanks for the query parameters, but i assume even if i pass them, it's still gonna behave like this. — Recoba20, Dec 21 '17 at 14:14
What do you mean by *"fails"*? The current one also fails, so I assume it's different somehow? Give a [mcve]. — jonrsharpe, Dec 21 '17 at 14:15

The data should be dumped:

a = requests.put(url, data=json.dumps([{"foo":"more_foo"}]))

or you can use the json key instead of data:

a = requests.post(url, json=[{"foo":"more_foo"}])

thank you for first editing my post and for providing me the missing part :) – Recoba20 Dec 21 '17 at 14:23
yes, it did :) I upvoted as well, let me know if u need something more. – Recoba20 Dec 21 '17 at 14:27
Can you then accept the answer so users know it solves the issue! – Dhia Dec 21 '17 at 14:28

Or you can pass a `json` payload using, perhaps unsurprisingly, `json=[{...}]`. You don't need to serialise it yourself. – jonrsharpe Dec 21 '17 at 14:31
Does it matter that the solution here changes the request from a PUT to a POST? – knowingpark Jan 31 '19 at 05:17
