命令行部署合约
启动环境：用geth启动一个以太坊节点：
进入到.../ethereuem/build/bin:
启动geth：
./geth --datadir walkertest/ --miner.etherbase 0x106cdbb5029d186ae6f659b52fb83179fc153e6a --mine --miner.threads 1 --rpc --rpcvhosts "*" --rpcaddr 0.0.0.0 --rpcport 8545 --rpccorsdomain "*" --rpcapi "db,eth,net,web3,personal,debug"
为了便于查看交互信息，再开一个窗口,启动console：
./geth attach /Users/.../walkertest/geth.ipc
编写合约代码：
pragma solidity >=0.4.21 < 0.6.0;
contract greeting {
string myStr;
constructor(string _myStr) public{
myStr = _myStr;
}
function getMystring() constant public returns (string){
return myStr;
}
function setMyString(string _myStr)public payable{
myStr =_myStr;
}
}
定义了一个名为greeting的智能合约，在智能合约初始化时保存了一个字符串，每次调用getMyString返回字符串，每次调用setMyString改变字符串。
编译合约
这里选择线上编译器将上面的合约编译，打开remix,将写好的合约代码粘贴进去。
点击Compile data.sol后，再点击Compilation Details,在弹出的对话框中找到WEB3DEPLOY部分，点拷贝。粘贴到sublime或者其他编辑器中：
var _myStr = "hello dataqin!";
var greetingContract = web3.eth.contract([{"constant":true,"inputs":[],"name":"getMystring","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_myStr","type":"string"}],"name":"setMyString","outputs":[],"payable":true,"stateMutability":"payable","type":"function"},{"inputs":[{"name":"_myStr","type":"string"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]);
var greeting = greetingContract.new(
_myStr,
{
from: web3.eth.accounts[0],

gas: '4700000'
}, function (e, contract){
console.log(e, contract);
if (typeof contract.address !== 'undefined') {
console.log('Contract mined! address: ' + contract.address + ' transactionHash: ' + contract.transactionHash);
}
})
代码内容解释:
第1行：修改过输入字符串为Hello dataqin!。
第2行：用eth.contract来定义一个合约类（ABI接口）。
第3行：部署创建合约实例，并修改合约实例名greetinng，之后可以直接用实例调用函数。
第4行：创建实例时的入参。
第6行：部署合约的账户，该账户需先解锁，不然会报错，这里用新账户部署。
第7行：data里为合约的编译后的二进制代码。
第8行：准备付的gas费用，IDE已经帮我们预估好了。
第9行：设置部署回调函数。
解锁账号，并保证改账号有足够的eth
> eth.accounts[0]
"0x106cdbb5029d186ae6f659b52fb83179fc153e6a"
> personal.unlockAccount("0x106cdbb5029d186ae6f659b52fb83179fc153e6a","walker")
true
> eth.getBalance("0x106cdbb5029d186ae6f659b52fb83179fc153e6a")
3.7287000066644e+22

执行部署合约
拷贝编辑好的代码到console，回车，看到返回结果：
Contract mined! address: 0x4b1d5efc2579689e5e935fb5ad842f9d186afca7 transactionHash: 0xafcbefe7b81da35cc5d55fe788cd38bc6f5624a2ed3f10bb0c97d70631452e09
运行合约
> greeting.getMystring()
"hello dataqin!"
> greeting.setMyString.sendTransaction('hello boy',{from:"0x106cdbb5029d186ae6f659b52fb83179fc153e6a", gas:3000000})
"0x08dcbd4d45487b8392586b1534416be4d26488c2f6b8764d716d515b4cf91edd"
> greeting.getMystring()
"hello dataqin!"
合约部署成功
在console中如何调用已经部署的合约？
从新打开一个console窗口
> abi = [{"constant":true,"inputs":[],"name":"getMystring","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_myStr","type":"string"}],"name":"setMyString","outputs":[],"payable":true,"stateMutability":"payable","type":"function"},{"inputs":[{"name":"_myStr","type":"string"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"}]
[{
constant: true,
inputs: [],
name: "getMystring",
outputs: [{
name: "",
type: "string"
}],
payable: false,
stateMutability: "view",
type: "function"
}, {
constant: false,
inputs: [{
name: "_myStr",
type: "string"
}],
name: "setMyString",
outputs: [],
payable: true,
stateMutability: "payable",
type: "function"
}, {
inputs: [{
name: "_myStr",
type: "string"
}],
payable: false,
stateMutability: "nonpayable",
type: "constructor"
}]
定义一个合约类
需要使用eth.contract来定义一个合约类
> data = eth.contract(abi)
{
abi: [{
constant: true,
inputs: [],
name: "getMystring",
outputs: [{...}],
payable: false,
stateMutability: "view",
type: "function"
}, {
constant: false,
inputs: [{...}],
name: "setMyString",
outputs: [],
payable: true,
stateMutability: "payable",
type: "function"
}, {
inputs: [{...}],
payable: false,
stateMutability: "nonpayable",
type: "constructor"
}],
eth: {

}
赋值合约地址
> newContract = data.at("0x4b1d5efc2579689e5e935fb5ad842f9d186afca7")
{
abi: [{
constant: true,
inputs: [],

}, {
constant: false,

transactionHash: null,
allEvents: function(),
getMystring: function(),
setMyString: function()
}
使用合约
> newContract.getMystring()
"hello dataqin!"
> newContract.setMyString.sendTransaction("you are the best man",{from:"0x106cdbb5029d186ae6f659b52fb83179fc153e6a",gas:3000000})
"0xf93fcce33f48015976b6beb2fb1809eba84e03abada5a69d5a74371d1e30bf06"
> newContract.getMystring()
"you are the best man"
测试成功！！
