Convert Python dictionary to a JSON array

Question

Here's my function which connects to an API:

def order_summary():
    """Get order summary for a specific order"""
    # Oauth2 params
    headerKey = api_login()
    headers = {'Authorization': headerKey}

    # Payload params
    payloadOrderSum = {
        "domainId": 15,
        "domainName": "SGL",
        "orderId": 3018361
    }

    # API response
    orderSumResp = requests.post(url + "order/summary", data=payloadOrderSum, headers=headers)
    print(orderSumResp.content)

The API expects a JSON array as Payload Params which essentially looks like that:

[
  {
    "domainId": 0,
    "domainName": "string",
    "orderId": 0
  }
]

The other endpoints I coded for on this API didn't need for the params to be an array so I could just use them as is and send them as a dictionary and it worked.

I've tried a couple things using the JSON library but I can't seem to get it to work. I saw that the JSonEncoder converts lists and tuples to JSON arrays but I couldn't figure it out.

Not sure what other info I could provide but just ask if there are any.

Thanks!

Wrap payloadOrderSum into a list:

payloadOrderSum = {
    "domainId": 15,
    "domainName": "SGL",
    "orderId": 3018361
}

orderSumResp = requests.post(url + "order/summary", json=[payloadOrderSum], headers=headers)

Note that I used json kwarg instead of data (added in version 2.4.2).

By far the easiest to solve it. Thanks! Don't even need the JSON library anymore. That REQUESTS library kicks ass!

dump your dict with json.dumps requests-doc

r = requests.post(url, data=json.dumps(payload))

It could help if you specify what you tried with the JSON library.

However, you might wanna try this if you haven't already done so:

import json
payloadOrderSum = json.dumps(
    {
    "domainId": 15,
    "domainName": "SGL",
    "orderId": 3018361
    }
)
