1. 代币的智能合约代码
pragma solidity ^0.4.2;
contract Token {
address issuer;
mapping (address => uint) balances;
event Issue(address account, uint amount);
event Transfer(address from, address to,uint amount);
function Token() {
issuer = msg.sender;
}
function issue(address account, uint amount) {
if (msg.sender != issuer) throw;
balances[account] += amount;
}
function transfer(address to, uint amount){
if (balances[msg.sender] < amount)throw;
balances[msg.sender] -= amount;
balances[to] += amount;
Transfer(msg.sender, to, amount);
}
function getBalance(address account)constant returns (uint) {
return balances[account];
}

2.合约代码编译 选择WEB3DEPLOY的编码,编译代码如下
var tokenContract = web3.eth.contract([{"constant":false,"inputs":[{"name":"account","type":"address"},{"name":"amount","type":"uint256"}],"name":"issue","outputs":[],"payable":false,"type":"function","stateMutability":"nonpayable"},{"constant":false,"inputs":[{"name":"to","type":"address"},{"name":"amount","type":"uint256"}],"name":"transfer","outputs":[],"payable":false,"type":"function","stateMutability":"nonpayable"},{"constant":false,"inputs":[],"name":"Token","outputs":[],"payable":false,"type":"function","stateMutability":"nonpayable"},{"constant":true,"inputs":[{"name":"account","type":"address"}],"name":"getBalance","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function","stateMutability":"view"},{"anonymous":false,"inputs":[{"indexed":false,"name":"account","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Issue","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"from","type":"address"},{"indexed":false,"name":"to","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Transfer","type":"event"}]);
var token = tokenContract.new(

console.log(e, contract);
if (typeof contract.address !== 'undefined') {
console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
}
})
3. 定义合约
注:编码后的第一行 本人测试需要去掉var 及结尾的分号; 才能执行成功
> tokenContract = web3.eth.contract([{"constant":false,"inputs":[{"name":"account","type":"address"},{"name":"amount","type":"uint256"}],"name":"issue","outputs":[],"payable":false,"type":"function","stateMutability":"nonpayable"},{"constant":false,"inputs":[{"name":"to","type":"address"},{"name":"amount","type":"uint256"}],"name":"transfer","outputs":[],"payable":false,"type":"function","stateMutability":"nonpayable"},{"constant":false,"inputs":[],"name":"Token","outputs":[],"payable":false,"type":"function","stateMutability":"nonpayable"},{"constant":true,"inputs":[{"name":"account","type":"address"}],"name":"getBalance","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function","stateMutability":"view"},{"anonymous":false,"inputs":[{"indexed":false,"name":"account","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Issue","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"from","type":"address"},{"indexed":false,"name":"to","type":"address"},{"indexed":false,"name":"amount","type":"uint256"}],"name":"Transfer","type":"event"}])
4. 合约部署上交易链
其实就是执行编码后的第二行代码
