Sending JSON with array of dicts with python-requests

Question

I'm trying to send json containing array of dicts with requests module. Here's sample of my code:

payload = {
    "arrayData": [
        {
            "key1": 1,
            "key2": 2,
            "key3": {
                "subkey": 3
            }
        }
    ]
}
r = requests.post(
    'https://httpbin.org/post',
    data = payload,
)
print(r.text)

Here's what I believe my request looks like:

{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "arrayData": [
      "key1", 
      "key2", 
      "key3"
    ]
  }, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Content-Length": "44", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.4"
  }, 
  "json": null, 
  "url": "https://httpbin.org/post"
}

The problem is arrayData at some moment turns to plain list of values.

It is crucial to my task to send that json as form but I'm out of ideas how to do that. Sending request with json=payload or with data=json.dumps(payload) doesn't do the trick because parsed data goes to "json" part but I need it in "form".

In my example arrayData contains only one dict, but there may be several.

Did you mean to send it as form data? Perhaps you may want to send JSON instead: `data=json.dumps(payload)` — cs95, Dec 16 '18 at 09:47
Yeah. I've tried that, it parses correctly but goes to "json" part and "form" becomes empty. — Rodriger, Dec 16 '18 at 09:53
It expects form with arrayData field that contains array of JSON dicts — Rodriger, Dec 16 '18 at 09:59

Turns out it was form with arrayData field and JSON content, so correct payload should be like this:

payload = {
"arrayData": json.dumps([{
    "key1": 1,
    "key2": 2,
    "key3": {
        "subkey": 3
        }
    }])
}
