python-bitcoinrpc-2sat 1.0.1

Installation

1. change the first line of setup.py to point to the directory of your installation of python 2.*

2. run setup.py

Note: This will only install bitcoinrpc. If you also want to install jsonrpc to preserve backwards compatibility, you have to replace ‘bitcoinrpc’ with ‘jsonrpc’ in setup.py and run it again.

Or simply install the library using pip:

pip install python-bitcoinrpc

Example

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException

# rpc_user and rpc_password are set in the bitcoin.conf file
rpc_connection = AuthServiceProxy("http://%s:%s@127.0.0.1:8332"%(rpc_user, rpc_password))
best_block_hash = rpc_connection.getbestblockhash()
print(rpc_connection.getblock(best_block_hash))

# batch support : print timestamps of blocks 0 to 99 in 2 RPC round-trips:
commands = [ [ "getblockhash", height] for height in range(100) ]
block_hashes = rpc_connection.batch_(commands)
blocks = rpc_connection.batch_([ [ "getblock", h ] for h in block_hashes ])
block_times = [ block["time"] for block in blocks ]
print(block_times)

Logging all RPC calls to stderr

from bitcoinrpc.authproxy import AuthServiceProxy, JSONRPCException
import logging

logging.basicConfig()
logging.getLogger("BitcoinRPC").setLevel(logging.DEBUG)

rpc_connection = AuthServiceProxy("http://%s:%s@127.0.0.1:8332"%(rpc_user, rpc_password))
print(rpc_connection.getinfo())

Produces output on stderr like

DEBUG:BitcoinRPC:-1-> getinfo [] DEBUG:BitcoinRPC:<-1- {“connections”: 8, …etc }

Socket timeouts under heavy load

Pass the timeout argument to prevent “socket timed out” exceptions:

rpc_connection = AuthServiceProxy(
    "http://%s:%s@%s:%s"%(rpc_user, rpc_password, rpc_host, rpc_port),
    timeout=120)
