9.3.1.2. 创建项目

			
cd ~/ethereum
mkdir truffle-project
cd truffle-project 
truffle init

操作演示

			
neo@netkiller ~/ethereum/truffle-project % truffle init
Downloading...
Unpacking...
Setting up...
Unbox successful. Sweet!

Commands:

  Compile:        truffle compile
  Migrate:        truffle migrate
  Test contracts: truffle test
  
neo@netkiller ~/ethereum/truffle-project % tree 
.
|-- contracts
|   `-- Migrations.sol
|-- migrations
|   `-- 1_initial_migration.js
|-- test
|-- truffle-config.js
`-- truffle.js

3 directories, 4 files

目录结构简单说明如下：



contract/ - Truffle默认的合约文件存放地址。
migrations/ - 存放发布脚本文件
test/ - 用来测试应用和合约的测试文件
truffle.js - Truffle的配置文件

app/ - 需要用户创建，应用文件运行的默认目录。

9.3.1.3. 创建合约

			
pragma solidity ^0.4.18;

contract Netkiller {
    string name;
    int num;
    function Netkiller() public{
        name = "default";
        num = 1;
    }
    function setName(string _name) public{
        name = _name;
    }
    function getName() public view returns(string){
        return name;
    }
    function setNum(int n) public{
        num = n;
    }
    function addNum(int m) public view returns(int res){
        res = m + num;
    }
}

			
				
			
neo@netkiller ~/ethereum/truffle-project % vim migrations/2_initial_migration.js

var Netkiller = artifacts.require("./Netkiller.sol");

module.exports = function(deployer) {
  deployer.deploy(Netkiller);
};

9.3.1.4. 配置 Truffle

打开文件 truffle.js

			
module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
};

修改为

			
module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
			
  networks: {
    development: {
      host: "localhost",
      port: 9545,
      network_id: "*" // Match any network id
    }
  }	
  		
};

9.3.1.5. 编译智能合约

			
neo@netkiller ~/ethereum/truffle-project % truffle compile
Compiling ./contracts/Migrations.sol...
Compiling ./contracts/Netkiller.sol...
Writing artifacts to ./build/contracts

truffle默认只会编译最后一次修改过的合约文件, 这是为了减少比重复编译。"--all"选项,可以强制编译所有文件。

编译结果

			
neo@netkiller ~/ethereum/truffle-project % find build 
build
build/contracts
build/contracts/Migrations.json
build/contracts/Netkiller.json

9.3.1.6. migrate

			
neo@netkiller ~/ethereum/truffle-project % truffle migrate      
Using network 'development'.

Network up to date.
