Question

我正在https://medium.com/@orweinberger/how-to-create-a-raw-transaction-using-bitcoinjs-lib-1347a502a3a#.wkf9g2lk0

关注bitcoinjs的教程

我收到

的未定义错误

var key = bitcoin.ECKey.fromWIF("L1Kzcyy88LyckShYdvoLFg1FYpB5ce1JmTYtieHrhkN65GhVoq73");

阅读https://github.com/bitcoinjs/bitcoinjs-lib/issues/487我改为使用

var key = bitcoin.ECPair.fromWIF("L1Kzcyy88LyckShYdvoLFg1FYpB5ce1JmTYtieHrhkN65GhVoq73");

对于行：console.log(key.pub.getAddress().toString());（来自教程）

我收到类似的例外：

TypeError: Cannot read property 'getAddress' of undefined
    at repl:1:20
    at REPLServer.defaultEval (repl.js:262:27)
    at bound (domain.js:287:14)

    at REPLServer.Interface._line (readline.js:550:8)
    at REPLServer.Interface._ttyWrite (readline.js:827:14)

'getAddress'方法也已弃用，而是使用什么？

发送比特币的其他任何教程？他们似乎很难找到？

Answer 1

这应该有效

var key = bitcoin.ECPair.fromWIF("L1Kzcyy88LyckShYdvoLFg1FYpB5ce1JmTYtieHrhkN65GhVoq73");
var address = key.getAddress().toString()

console.log(address) // 17hFoVScNKVDfDTT6vVhjYwvCu6iDEiXC4

Answer 2

最好还是使用较新版本的bitcoin.js库

const bitcoin = require('bitcoinjs-lib');
let keyPair = bitcoin.ECPair.makeRandom();
let publicKey = keyPair.publicKey
const { address } = bitcoin.payments.p2pkh({ pubkey: publicKey });
const privateKey = keyPair.toWIF();
console.log(address)
console.log(privateKey)

使用bitcoinjs-lib发送比特币
