Token开发步骤
一、准备工具
1.安装以太坊
brew tap ethereum/ethereum
brew install ethereum
2.node：brew install nodejs
3.安装依赖库：npm install -g ganache-cli web3 solc truffle truffle-contract zeppelin-solidity
4.运行ganache-cli，端口默认是8545
5.配置myetherwallet设置自定义的网络：https://www.myetherwallet.com/
6.安装vs code
7.安装MetaMask插件（Chrome），配置网络同myetherumwallet
二、开发
1.truffle unbox vue-box, 其他的box可以在http://truffleframework.com/boxes/中找到
2.新建自己的Contract，示例代码如下：
pragma solidity ^0.4.18;
import "zeppelin-solidity/contracts/token/ERC20/StandardToken.sol";
contract FirstToken is StandardToken {
string public name = "FirstToken";
string public symbol = "FST";
uint public decimals = 18;
uint public INITIAL_SUPPLY = 10000 * (10 ** decimals);
function FirstToken() public {
balances[msg.sender] = INITIAL_SUPPLY;
}
}
3.编辑migrations\2_deploy_contracts.js增加自己编写的Contract的部署代码:deployer.deploy(FirstToken);
4.配置项目的truffle.config中的网络，确保端口是8545
5.运行truffle comiple 编译contract
6.运行truffle migrate --reset部署网络
7.新建自己的测试页面，关键代码如下：
<script>
import Web3 from 'web3'
import contract from 'truffle-contract'
import artifacts from '../../build/contracts/FirstToken.json'
const FirstTokenContract = contract(artifacts) export default {
name: 'FirstToken',
data() {
return {
web3: null,
account: null,
token: null,
address: '0x554f40f004758c2043992379465a04371ffdd9e1',
num: 10,
result: null
}
},
created() {
if (typeof web3 !== 'undefined') {
this.web3 = Object.freeze(new Web3(web3.currentProvider))
} else {
this.web3 = new Web3(new Web3.providers.HttpProvider("http://127.0.0.1:8545"))
}
FirstTokenContract.setProvider(this.web3.currentProvider)
this.account = this.web3.eth.coinbase
this.web3.eth.defaultAccount = this.web3.eth.coinbase
FirstTokenContract.defaults({from: this.web3.eth.coinbase})
FirstTokenContract.deployed().then((instance) => {
instance.balanceOf(this.account).then((value) => this.token = value)
});
},
methods: {
send() {
return FirstTokenContract.deployed()
.then((instance) => {
console.log('from:' + this.account)
console.log('to:' + this.address);
instance.transfer(this.address, this.num)
return instance
})
.then((instance) => {
instance.balanceOf(this.address).then((value) => this.result = value)
instance.balanceOf(this.account).then((value) => this.token = value)
})
.catch((e) => {
console.error(e)
})
},
query() {
return FirstTokenContract.deployed()
.then((instance) => {
instance.balanceOf(this.address).then((value) => this.result = value)
})
.catch((e) => {
console.error(e)
})
},
}
}
</script>
8.运行send方法的时候注意要在MetaMask中点击提交才会真正执行
