How to send a POST request with JSON body?

I am trying to send a POST request. For this request, I want to send a JSON in the body but this is not working and it gives an error saying: can't concat str to bytes. What is the correct way to submit a POST request with a JSON body?

import http.client, urllib.parse

def update_status(status, versionId):
    conn = http.client.HTTPConnection(server_ip, server_port)
    body = {
        "status": status,
        "id": versionId
    }
    print("body:", body)
    headers = {"Content-type": "application/json"}
    conn.request("POST", "", body, headers)
    response = conn.getresponse()
    print("response status:", response.status)
    print("response reason:", response.reason)
    return response
return update_status

You need to serialize data first.

data = json.dumps(body)
data = data.encode('utf8')
conn.request("POST", "", data, headers)

Consider using requests module. As easy as it looks below:

import requests

body = {"key": "value"}
response = requests.post("http://<SOME_URL>", json=body)
