web3js 进行转账

1、准备阶段

部署以太坊geth

安装nodejs

npm install web3

npm install

npm install ethereumjs-tx

2、在部署有geth的机器上，执行node命令，就入控制台模式，然后逐行执行下面程序：

const Web3 = require('web3')
const EthereumTx = require('ethereumjs-tx')
const web3 = new Web3( new Web3.providers.HttpProvider('http://localhost:8145') )
web3.eth.defaultAccount = 'af7574a21729d22e119df7456bf913194d73c209'
const amountToSend = 0.00100000

let details = {
    "to": '0x5cf83df52a32165a7f392168ac009b168c9e8915',
    "value": 998100000,
    "gas": 21000,
    "gasPrice": 50 * 1000000000, 
    "nonce": 11,
    "chainId": 11243575 
  }

var tx = new EthereumTx(details)
tx.sign( Buffer.from('FC1A5C66932BD7C93E05661A58FD534967739CE517D8695EBBE89135CEE78DA4', 'hex') )
var serializedTx = tx.serialize();
web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex')).on('receipt', console.log);

输出输出：

Promise {
<pending>,
_events: { receipt: EE { fn: [Function: bound ], context: [Circular], once: false } },
emit: [Function: emit],
on: [Function: on],
once: [Function: once],
off: [Function: removeListener],
listeners: [Function: listeners],
addListener: [Function: on],
removeListener: [Function: removeListener],
removeAllListeners: [Function: removeAllListeners] }

输出(这里等待了很长时间)：
