ABI-encoded 实际上就是构造方法变量数据

		
var abi = require('ethereumjs-abi')

var parameterTypes = ["address", "uint256", "bool"];
var parameterValues = ["0x1234567812345678", "0x314159268", true];

var encoded = abi.rawEncode(parameterTypes, parameterValues);

console.log(encoded.toString('hex'));

还有一种方法可以找到 ABI 数据 https://etherscan.io/tx/0xc53f52b287ec1c71e9d203dd08cc68035ef40bf5155f8b0711da227c01d84d70 查看 Input Data: 0029之后所有的数据就是 ABI
