以太坊合约调用 transaction data 格式为：
method id(前4个字节) + 各个参数描述，具体规律还未知

【例】
contract HelloWorld {
    string public name;
    uint256 public age;
    address public addr;

    event StudentAdded(string indexed name, uint256 age, address indexed _addr);

    }

    function save2(string s1, string s2, string s3) external {

    }
