Steem Engine
The python library uses a rpc client to communicate with the steem-engine.com json RPC server. All descripted methods at https://github.com/harpagon210/steemsmartcontracts/wiki/JSON-RPC-server have been implemented.
Furthermore a website api call for receiving account transfer history is supported.
Technology Stack
The library uses a rpc client based on the requests library for receiving data from the steem-engine.com JSON RPC server.
Any function call from the RPC class is translated into a RPC JSON call
rpc.find({"contract": contract_name, "table": table_name, "query": query,
"limit": limit, "offset": offset, "indexes": indexes}, endpoint="contracts")
will be converted to:
{
"jsonrpc": "2.0",
"method": "find",
"params": {
"contract": "contract_name",
"table": "table_name",
"query": query,
"limit": limit,
"offset": offset,
"indexes":indexes}
},
"id": 1
}
with the RPC JSON server url:
https://api.steem-engine.com/rpc/contracts"
All possible calls have been collected in the Api class.
Installation
The python package can be installed by:
pip install steemengine
Usage
Get the latest block of the sidechain
from steemengine.api import Api
api = Api()
print(api.getLatestBlockInfo())
Get the block with the specified block number of the sidechain
from steemengine.api import Api
api = Api()
print(api.getBlockInfo(1910))
Retrieve the specified transaction info of the sidechain
from steemengine.api import Api
api = Api()
print(api.getTransactionInfo("e6c7f351b3743d1ed3d66eb9c6f2c102020aaa5d"))
Get the contract specified from the database
from steemengine.api import Api
api = Api()
print(api.getContract("tokens"))
Get an array of objects that match the query from the table of the specified contract
from steemengine.api import Api
api = Api()
print(api.find("tokens", "tokens"))
Get the object that matches the query from the table of the specified contract
from steemengine.api import Api
api = Api()
print(api.findOne("tokens", "tokens"))
Get the transaction history for an account and a token
from steemengine.api import Api
api = Api()
print(api.get_history("holger80", "NINJA"))
Roadmap
The next step will be using the beem library for sending token.
I'm planing also a command line tool for viewing token balances and sending token.
