使用truffle汇总
truffle主要用来批量编译和部署合约，不再想remix进行手动一个一个部署，可大大提高部署效率。
常用的命令是：
truffle compile，编译成json文件，包含字节码等
truffle migrate/deploy，部署
truffle exec，执行（Execute a JS module within this Truffle environment）
还在学习中，慢慢补充。
写自己的脚本，运行

如何运行：
truffle exec your_file.js --network testnet
factory合约的方法 pairCodeHash() 里有一个 type(c).creationCode，其实取的是合约的字节码字段（truffle compile后），即bytecode字段。
type(c).name:获得合约的名字 type(c).creationCode:获得创建合约的字节码 type(c).runtimeCode:获得合约运行时的字节码
