异步以太坊实用程序，
asynceth的Python项目详细描述
异步
异步以太坊jsonrpc库
安装
pip install asynceth
用法示例
import asyncio
from asynceth import JsonRPCClient
from asynceth import Contract
async def example_jsonrpc_request():
client = JsonRPCClient("http://localhost:8485")
balance = await client.eth_getBalance("0x0000000000000000000000000000000000000000")
print(balance)
asyncio.get_event_loop().run_until_complete(example_jsonrpc_request())
greeter_code = """
contract Greeter is Mortal {
/* Define variable greeting of the type string */
string greeting;
/* This runs when the contract is executed */
function Greeter(string _greeting) public {
greeting = _greeting;
}
/* Main function */
function greet() constant returns (string) {
return greeting;
}
}
"""
# NOTE: example requires `solc` to be installed, and private_key must be the private key to an
# account on the ethereum node pointed to by JsonRPCClient that has funds to deploy the contract
private_key = os.urandom(32)
async def example_contract_deployment():
client = JsonRPCClient("http://localhost:8485")
greeter = await Contract(client, greeter_code).set_signer(private_key).deploy("Hello World")
greeting = await greeter.greet()
assert greeting == "Hello World"
asyncio.get_event_loop().run_until_complete(example_contract_deployment())
运行测试
