以太坊智能合约构造函数初始化解密

1.编译智能合约源代码得到code
2.部署智能合约
参考rpc命令，web3有完善的接口
curl -X POST --data '{"jsonrpc":"2.0","method":"eth_sendTransaction","params":[{"from":"0xCD2a3d9F938E13CD947Ec05AbC7FE734Df8DD826","data":"........."}],"id":1}' http://192.168.10.18:7000/rpc
3.构建data举例，智能合约

pragma solidity ^0.4.24;
contract RI {
    // The keyword "public" makes those variables
    // readable from outside.
    address public minter;
    mapping (address => uint) public balances;
    string public accounts;

    // Events allow light clients to react on
    // changes efficiently.
    event Sent(address from, address to, uint amount);

    // This is the constructor whose code is
    // run only when the contract is created.
    constructor (uint apply,string users) public {
        minter = msg.sender;
        balances[msg.sender]=apply;
        accounts=users;
    }

    function mint(address receiver, uint amount) public {
        if (msg.sender != minter) return;
        balances[receiver] += amount;
    }

    function send(address receiver, uint amount) public {
        if (balances[msg.sender] < amount) return;
        balances[msg.sender] -= amount;
        balances[receiver] += amount;
        emit Sent(msg.sender, receiver, amount);
    }
}

4.没有构造器参数的时候，部署智能合约应该发送data

6.上面加粗部分，表达了带参数的时候只能合约的code不同之处。
如果要仔细体会和分析，可以在geth控制台执行web3.fromAscii来分析。
