VUE項目中的獲取助記詞的方式

安裝需要的依賴環(huán)境

如果你安裝了國內的淘寶鏡像了 ，建議你用cnpm
bip39：npm install bip39
bip32：npm install bip32
ethereumjs-util：npm install ethereumjs-util
bitcoinjs-lib:npm install bitcoinjs-lib
這個我不知道怎么回事，安裝不上需要python環(huán)境，這個是別人給弄得
代碼如下：

var bitcoin = require('bitcoinjs-lib') var bip39 = require('bip39') var bip32 = require('bip32') var ethUtil = require("ethereumjs-util");var mnemonic = bip39.generateMnemonic() // 存到localStorage中單詞 var mnemonicArr = mnemonic.replace(/\s+/g, ',').split(','); localStorage.setItem('mnemonic', JSON.stringify(mnemonicArr)) // console.log("助記詞：" + mnemonic)var seedHex = bip39.mnemonicToSeedHex(mnemonic); // console.log(seedHex); var seed = bip39.mnemonicToSeed(mnemonic) // console.log(seed) var seedAsHex = seed.toString('hex');// 存到localStorage中bip39種子 localStorage.setItem('seed', JSON.stringify(seedAsHex)) // console.log("種子：" + seedAsHex);var masterKey = bitcoin.HDNode.fromSeedHex(seed, bitcoin.networks.bitcoin) // console.log("BTC");// 存到localStorage中bip39種子 localStorage.setItem('masterKey', JSON.stringify(masterKey.toBase58())) // console.log("root Key：" + masterKey.toBase58())var bip32ExtendedKey = masterKey.derivePath("m/44'/0'/0'/0"); // console.log("btc：BIP32 Extended Private Key：" + bip32ExtendedKey.toBase58())var key = bip32ExtendedKey.derive(0); // console.log(key); var keyPair = key.keyPair; // console.log(keyPair); var address = keyPair.getAddress().toString(); // 存到localStorage中btc公鑰還有密鑰 localStorage.setItem('BTCaddress', JSON.stringify(address)) // console.log("btc地址：" + address); var privkey = keyPair.toWIF(); // 存到localStorage中btc私鑰 localStorage.setItem('privBTC', JSON.stringify(privkey)) // console.log("btc私鑰：" + privkey); var pubkey = keyPair.getPublicKeyBuffer().toString('hex'); localStorage.setItem('publBTC', JSON.stringify(pubkey)) // console.log("btc公鑰：" + pubkey);var bip32ExtendedKey = masterKey.derivePath("m/44'/60'/0'/0"); // console.log("ETH：BIP32 Extended Private Key：" + bip32ExtendedKey.toBase58()) key = bip32ExtendedKey.derive(0);// console.log(key);var keyPair = key.keyPair; var address = keyPair.getAddress().toString(); var privkey = keyPair.toWIF(); var pubkey = keyPair.getPublicKeyBuffer().toString('hex'); var privKeyBuffer = keyPair.d.toBuffer(32); privkey = privKeyBuffer.toString('hex'); var addressBuffer = ethUtil.privateToAddress(privKeyBuffer); address = ethUtil.addHexPrefix(ethUtil.toChecksumAddress(ethUtil.privateToAddress(privKeyBuffer).toString('hex'))); privkey = ethUtil.addHexPrefix(privkey); pubkey = ethUtil.addHexPrefix(pubkey); // eth的公鑰私鑰 地址 localStorage.setItem('ETHaddress', JSON.stringify(address)) localStorage.setItem('publETH', JSON.stringify(privkey)) localStorage.setItem('privETH', JSON.stringify(pubkey)) // // console.log("ETh地址：" + address); // console.log("ETh私鑰：" + privkey); // console.log("ETh公鑰：" + pubkey);
