Using python 'requests' to send JSON boolean

Question

I've got a really simple question, but I can't figure it out how to do it. The problem I have is that I want to send the following payload using Python and Requests:

{ 'on': true }

Doing it like this:

payload = { 'on':true }
r = requests.put("http://192.168.2.196/api/newdeveloper/lights/1/state", data = payload)

Doesn't work, because I get the following error:

NameError: name 'true' is not defined

Sending the true as 'true' is not accepted by my server, so that's not an option. Anyone a suggestion? Thanks!

I know that it's True. But when I put 'True' there, the payload will be "{'on': True}". I want it to be "{'on': true}" — Erik Pragt, Jul 31 '13 at 20:40
You need to json encode it to get it to a string. `import json` `payload = json.dumps({"on":True})` — GP89, Jul 31 '13 at 20:41
can boolean data be send over GET params? I tried using python-requests, but Other side I am receiving string data. I want to pass some some boolean (true/false) data. — OmPrakash, Sep 19 '17 at 14:45
@OmPrakash GET data has to be a string yes, it's just part of the URL. if you are using json you can just use `json.loads(data)` to convert it back on the server, or whichever appropriate deserialisation. — GP89, Jun 06 '18 at 07:39

You need to json encode it to get it to a string.

import json 
payload = json.dumps({"on":True})

doesn't this still give out "on" and "True" ? – Justin Farrugia Apr 14 '19 at 20:02

Starting from requests 2.4.2, instead of passing in the payload with the data parameter, you can use the json parameter like this:

payload = {'on': True}
requests.put(url, json=payload)

And the request will be formatted correctly as a json payload (i.e. {'on': true}).

should be {'on': True}, capital T

That doesn't work. I want the payload to be {'on':true}. This will turn the payload into {'on':True}, which unfortunately doesn't work. – Erik Pragt Jul 31 '13 at 20:41
that is because you need to dump the dictionary using json. For example, when you have payload={"on": True}, do json.dumps(payload) – Conan Li Jul 31 '13 at 20:50
Passing a proper Boolean object helped us ie True / False – RICHA AGGARWAL Aug 30 '16 at 10:25

to make it be lower case like that (if that's what your endpoint requires) do in quotes {'on':'true'}
