Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call:
>>> import requests
>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})
>>> r.status_code
200
>>> r.json()
{'args': {},
'data': '{"key": "value"}',
'files': {},
'form': {},
'headers': {'Accept': '*/*',
'Accept-Encoding': 'gzip, deflate',
'Connection': 'close',
'Content-Length': '16',
'Content-Type': 'application/json',
'Host': 'httpbin.org',
'User-Agent': 'python-requests/2.4.3 CPython/3.4.0',
'X-Request-Id': 'xx-xx-xx'},
'json': {'key': 'value'},
'origin': 'x.x.x.x',
'url': 'http://httpbin.org/post'}

It turns out I was missing the header information. The following works:
import requests
url = "http://localhost:8080"
data = {'sender': 'Alice', 'receiver': 'Bob', 'message': 'We did it!'}
headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
r = requests.post(url, data=json.dumps(data), headers=headers)
I'm not sure that PHP can automatically parse JSON into $_POST variables. You should put the JSON into the value of a normal POST variable:
request.send('data=' + encodeURIComponent(JSON.stringify(objJSON));
and use the default Content-Type. Then in PHP you can do:
var_dump(json_decode($_POST['data']));
You also need to fix a Javascript variable, as explained in Niels Keurentjes's answer.
Breaking your function down to its core 3 lines:
function ajax_call(src, jsonObj, dst, method) {
jsonOBJ is set in local scope as a variable.
this.objJSON = jsonObj;
jsonOBJ is copied to this.objJSON.
sendPostRequest(objJSON);
There is still no local variable objJSON since Javascript does not automatically consider this part of the local scope, hence null is sent, hence the empty $_POST.
Send jsonOBJ or this.objJSON instead and it'll work fine.
