RC12 returns invalid status codes on JSON RPC calls

[stephantual]

The RC12 JSON RPC server (ethereum -rpc=true) seems to return invalid status code (blank) no matter what I throw at it:

Using OSX latest, Python 3.4+requests+json-rpc transport confirmed to work on google.com URLs + confirmed to work with 3rd party RPC servers installed locally, etc:

import requests 
import json

def main():
    url = "http://127.0.0.1:8080"

    response = requests.get(url)

    print(response)


if __name__ == "__main__":
    main()

Returns:

requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=8080): Max retries exceeded with url: / (Caused by <class 'http.client.BadStatusLine'>: '')

Tried all sorts of combinations such as:

    url = "http://127.0.0.1:8080"
    headers = {'content-type': 'application/json'} # TODO: might not be required

    payload = {
        "method": "EthereumAPI.GetKey",
        "jsonrpc": "2.0"
    }

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

    print(response)

... to no avail. Since this work with other RPC servers I suspect this is related to go ethereum

Update: just to confirm, the requests are making their way through because ethereum spits out "2014/06/15 19:57:24 [JSON] Incoming request." whenever I call it, with no further comments

You are using HTTP, the RPC server works over TCP.
