2.3验证部署
现在打开控制台，与kovan测试网络上的智能合约进行交互:
$ truffle console --network kovan
在控制台中执行：
【部署智能合约到公链】truffle(kovan)> MyContract.deployed().then((c) => { contract = c })
然后：
truffle(kovan)> contract.get()'myValue'truffle(kovan)> contract.set("hello world"){ tx:'0x7bf63444f3a7bd70e981a7bd49228b1cf1a8c3754daf64c4c7765b8eee46bf37',receipt:{ blockHash:'0xe03d0f43d85f4e41c18a90aa563ebda08899c6b9c38d0cd7779937046e2aed0c',blockNumber: 13447763,contractAddress: null,cumulativeGasUsed: 33629,from: '0x29920e756f41f8e691ae0b12d417c19204371e91',gasUsed: 33629,logs: [],logsBloom:'0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000',root: null,status: true,to: '0x4d3cfaf8457cea76c0409f989f9870115b4d2d82',transactionHash:'0x7bf63444f3a7bd70e981a7bd49228b1cf1a8c3754daf64c4c7765b8eee46bf37',transactionIndex: 0,rawLogs: [] },logs: [] }truffle(kovan)> contract.get()'hello world'
可以看到智能合约已经成功部署 。
3.脚本
包含一个脚本运行器，可对以太坊网络执行自定义脚本 。
让我们创建一个脚本并执行 。
在项目根目录下，创建.js文件，内容如下：
module.exports = function(callback) {web3.eth.getBlock('latest').then(console.log)}
该脚本将从Kovan测试网络获取最新区块的信息 。
执行脚本:
truffle exec script.js --network kovan
输出：
