使用truffle框架部署合约

1 安装truffle framework

$ sudo npm install -g truffle

【注意】先安装node.js node.js的安装可以参考:https://blog.csdn.net/u014361775/article/details/78865582

查看truffle的版本: $ truffle version

$ truffle version
Truffle v4.1.13 (core: 4.1.13)
Solidity v0.4.24 (solc-js)

2 通过truffle创建项目

通过truffle init命令创建项目

$ truffle init
Downloading...
Unpacking...
Setting up...
Unbox successful. Sweet!

Commands:

  Compile:        truffle compile
  Migrate:        truffle migrate
  Test contracts: truffle test

创建的项目结构如下:

$ tree
.
└── demo01
    ├── contracts
    │   └── Migrations.sol
    ├── migrations
    │   └── 1_initial_migration.js
    ├── test
    ├── truffle-config.js
    └── truffle.js

3 编写简单的合约

在contracts目录下新建HelloWord.sol文件,内容如下:

pragma solidity ^0.4.4;

contract HelloWorld {
    function test() pure public returns (string) {
        
      return "HelloWorld";
        
    }
}

4 编译合约

打开truffle的控制台: $ truffle develop

$ truffle develop
Truffle Develop started at http://127.0.0.1:9545/

Ensure you do not use it on production blockchains, or else you risk losing funds.

truffle(develop)> 

进行编译 truffle(develop)> compile

truffle(develop)> compile
Compiling ./contracts/HelloWorld.sol...
Compiling ./contracts/Migrations.sol...
Writing artifacts to ./build/contracts

truffle(develop)>

可以在工程目录下看到生成了一个build文件夹,里面是合约的字节码文件。

5 部署合约

在migrations文件夹下新建2_delploy_helloworld.js文件,内容如下:

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

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

部署命令: truffle(develop)> migrate

如果是第二次编译,则用: truffle(develop)> migrate --reset

truffle(develop)> migrate
Using network 'develop'.

6 调用合约中的方法

truffle(develop)> let contract;
undefined
truffle(develop)> contract = HelloWorld.deployed().then(instance => contract = instance)
