Python asks for POST error 400

I have searched many questions similar to mine, but I could not find a solution.

I am using requests to make a POST request. I've tried many combinations inside the request, but nothing returns 201 ok.

Here is my code:

 import json
 import requests

 if __name__ == '__main__':

    headers = {'content-type' : 'application/json'}
    url = "http://myserver/ext/v3.1/test_device"
    message = {"atribute_a": "value", "atribute_b": "valueb"}
    params = {"priority":"normal"}

    r = requests.post(url, params=params, headers=headers, data = json.dumps(message) )
    print(r)

I also tried using json.dumps but it also gives me 400 bad requests. I've also tried adding parameters directly to the url, like: ...? Priority = normal, but no success.

Based on the comments, your server is actually expecting the data to be a compressed JSON object. As far as parameters are concerned, it will most likely help if they are declared as tuples of tuples (or dict of dicts)

Try the following:



headers = {
    'content-type': 'application/json',
}

params = (
    ('priority', 'normal'),
)

data = {
    "atribute_a": "value",
    "atribute_b": false
}

requests.post(url, headers=headers, params=params, data=str(data))
