運(yùn)行npm install -g truffle

創(chuàng)建項(xiàng)目文件夾MetaCoin，運(yùn)行truffle unbox metacoin:
有以下文件夾：

migrations/ 可腳本化的部署文件

test/ 測(cè)試文件

truffle.js Truffle的配置文件

運(yùn)行truffle compile，編譯結(jié)果會(huì)放在buildcontracts

注：此處用truffle.cmd是因?yàn)樵赪indows系統(tǒng)下存在“命名沖突”的問(wèn)題。

運(yùn)行Truffle Develop：truffle develop，會(huì)給出10個(gè)賬號(hào)和私鑰供本地開(kāi)發(fā)使用

在Truffle Develop的運(yùn)行環(huán)境下，命令行可以省略truffle，運(yùn)行migrate，會(huì)顯示交易的ID和部署的智能合約的地址

GANACHE其實(shí)是一個(gè)有圖形界面的Truffle Develop客戶端

下載GANACHE

修改truffle.js的配置:

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*"
    }
  }
};

啟動(dòng)GANACHE

在控制臺(tái)輸入truffle migrate

結(jié)果類(lèi)似于上節(jié)相應(yīng)的操作

點(diǎn)擊“Transaction”按鈕可以查看交易的詳細(xì)過(guò)程。

查看賬戶0的metacoin的余額：

MetaCoin.deployed().then(function(instance){return instance.getBalance(web3.eth.accounts[0]);}).then(function(value){return value.toNumber()});

運(yùn)行結(jié)果：

10000

查看賬戶0的metacoin的余額的ether價(jià)值：

MetaCoin.deployed().then(function(instance){return instance.getBalanceInEth(web3.eth.accounts[0]);}).then(function(value){return value.toNumber()});

運(yùn)行結(jié)果：

20000

因?yàn)樵谶@個(gè)例子中，一個(gè)metacoin值2個(gè)ether

從賬戶0轉(zhuǎn)賬500個(gè)metacoin給賬戶1

MetaCoin.deployed().then(function(instance){return instance.sendCoin(web3.eth.accounts[1], 500);});

運(yùn)行結(jié)果：
