Unsupported media type

[heikoheiko]

Hi, when trying to access via http i get "Unsupported media type" as a return value.
running with ethersim

from pyethapp import rpc_client
c = rpc_client.JSONRPCClient(8101)
c.blocknumber()

sent:
{
  "jsonrpc": "2.0", 
  "method": "eth_blockNumber", 
  "id": 6
}
received:
Unsupported media type

this works when using geth or pyethapp.

I tried with web3.py as well.

While testing with web3.py ((https://github.com/pipermerriam/web3.py )) we get this error

This was an issue with web3.py not sending a content-type header which was fixed with https://github.com/pipermerriam/web3.py/pull/67 and is available as 1.8.0 from pypi or within the releases section of the repository.

[heikoheiko]

needs to be fixed in pyethapp too
