POST 请求列表 python-requests

Question

I am trying to POST Boxes = [{'X': 2423, 'Y': 532, 'W': 7456, 'H': 2345}] to the DRF server, I receive status code 200, However, on the server, I receive weird format: "Boxes": "[{\"X\": 1028, \"Y\": 228, \"W\": 711, \"H\": 852}]" .

I don't understand where the '/' comes from.

Here is the POST request in python:

                Boxes = [{"X": 2423, "Y": 532, "W": 7456, "H": 2345}]

                
                url = "http://art1x.pythonanywhere.com/snippets/1/"
                username = "artemii"
                password = "admin"
                data = {"Boxes": json.dumps(Boxes)}
                response = requests.put(url, auth=(username, password), data=data)
                print(response.status_code)

'Boxes' is a list

Please help! Any suggestion is valuable

Answer 1

The weird format looks like escape characters. Setting content type should fix this i think.

eg:

headers["Content-Type"]="application/x-www-form-urlencoded"

Remove json.dumps if you want to send Boxes as json object instead of a string:

data = {"Boxes": Boxes}

json.dumps(Boxes) convert Boxes into a string. requests.put then convert data into string for transport, where it inserts escape characters because the content is a string.
