python调用jsonrpc接口_Python interface to bitcoins JSON-RPC API

python-bitcoinrpc AuthServiceProxy is an improved version of python-jsonrpc. It includes the following generic improvements: HTTP connections persist for the life of the AuthServiceProxy object sends protocol version, per JSON-RPC 1.1 sends proper, incrementing id uses standard Python json lib can optionally log all RPC calls and results JSON-2.0 batch support It also includes the following bitcoin-specific details: sends Basic HTTP authentication headers parses all JSON numbers that look like floats as Decimal,

and serializes Decimal values to JSON-RPC connections. Installation change the first line of setup.py to point to the directory of your installation of python 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 []
