OctoPrint API, error 400 when making a POST request-CodePudding

I'm working with Octoprint's API. I'm struggling trying to issue commands to the 3d printer.

For example, I want to issue a command that makes the 3d printer jog the X-axis.

import requests
headers = {"Authorization": "Bearer <token>"}

def Beep():
  api_link = "http://octopi.local/api/printer/command"
  params = {"command":"jog","x":10}
  return requests.post(api_link, headers=headers, params=params)

The output of this code is <Response 400> (bad request). What I am missing?

CodePudding user response：

From the API documentation:

If not otherwise stated, OctoPrint’s API expects request bodies and issues response bodies as Content-Type: application/json.

Your request is not sending JSON. Use this instead:

requests.post(api_link, headers=headers, json=params)

Also, it looks like the jog command is supposed to use the url path /api/printer/printhead.
