node.js - 使用 bitcoinjs-lib 发送比特币

Question

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

我收到未定义的错误

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

阅读https://github.com/bitcoinjs/bitcoinjs-lib/issues/487我用的是

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

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

我收到类似的异常:

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.runBound [as eval] (domain.js:300:12)

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

“getAddress”方法也已弃用，可以使用什么代替？

还有其他发送比特币的教程吗？他们似乎很难找到？

这应该有效

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

console.log(address) // 17hFoVScNKVDfDTT6vVhjYwvCu6iDEiXC4
