钱包账号
neo钱包主要包括address,privateKey,publicKey,scriptHash,WIF这几个部分；它们之间存在一定的转化关系：
NEP<=>WIF <=> Private => Public => ScriptHash <=> Address
不开玩笑，除了 address 可以告诉别人以外，其它的对谁都不要说，address类似一个银行卡号，是别人想给你转账的时候使用的
创建钱包账号
import { wallet } from '@cityofzion/neon-js';
/**
* 根据passpase生产一个新的neo账号
* @param {*} passphase
* @param {*} confirmPassphase
* @param {*} wif
*/
export function createWalletAccount(passphase: string, confirmPassphase: string, wif?: string): ?WalletAccount {
if (passphase !== confirmPassphase) return null;
var account = new wallet.Account(wif || wallet.generatePrivateKey());
const encryptedWIF = wallet.encrypt(account.WIF, passphase);
const result: WalletAccount = {
address: account.address,
privateKey: account.privateKey,
publicKey: account.publicKey,
scriptHash: account.scriptHash,
WIF: account.WIF,
encryptedWIF,
passphase,
}
return result;
}
创建钱包账号单元测试
通过jest对创建钱包的方法进行单元测试
test('createWalletAccount ', () => {
const passphase = '123456';
const account = createWalletAccount(passphase, passphase);
console.log(account);
expect(account.address !== null).toBe(true);
});
运行结果如下所示，就是当前生成的账号信息，可以使用neo-wallet登录一下试试。
{
address: 'AUMgtJsw3kBrcA7poBYNaonZTGMNoqZNLy',
privateKey: '10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba',
publicKey: '03af2ad8725c4926632d6816f5502d8f749dec369afadfe0bb5ac697fe22a0ef77',
scriptHash: 'a8f677c132f2c82d73ff138e817e784c25ab068a',
WIF: 'KwnETPM2m8wTAY3qySvDVLf3Vpfg77nvJhxR2Qyi8uMWKoqP1Q3f',
encryptedWIF: '6PYVHykkA1TfyQ2344wftv5e7vRoecV4iVwEVZ62aqCAx3dh3LDrRV19AS',
passphase: '123456'
}
转化
正如前面所述的，钱包里的各个数据存在一定的转化关系，至于详细的相互之间转化的原理，先不至讨论，我们可以使用neon-js的相关API来查看是否正确转化。
NEP<=>WIF <=> Private => Public => ScriptHash <=> Address
下面先新建一个jtest的单元测试文件Core.spec.js
私钥到公钥的转化
这里使用上面生成的测试账号进行测试，注意因为是测试账号以后我不会再使用，所以暴露出来，如果是你的个人账号，请一定不要暴露WIF以及privateKey。
单元测试代码如下：
import {wallet} from '@cityofzion/neon-js';
test('private:10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba get PUb_Key',()=>{
const pubKey = wallet.getPublicKeyFromPrivateKey('10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba');
expect(pubKey).toBe('03af2ad8725c4926632d6816f5502d8f749dec369afadfe0bb5ac697fe22a0ef77');
});
使用命令运行单元测试：
npm run test __test__/neo/Core.spec.js
运行结果：
所有转化
完整的转化关系如下：
import {wallet} from '@cityofzion/neon-js';
const walletAccount = {
address: 'AUMgtJsw3kBrcA7poBYNaonZTGMNoqZNLy',
privateKey: '10bb026b4015c481f0b5142aa5de36de40a99fc8c26e956011a3f820f7708fba',
publicKey: '03af2ad8725c4926632d6816f5502d8f749dec369afadfe0bb5ac697fe22a0ef77',
scriptHash: 'a8f677c132f2c82d73ff138e817e784c25ab068a',
WIF: 'KwnETPM2m8wTAY3qySvDVLf3Vpfg77nvJhxR2Qyi8uMWKoqP1Q3f',
encryptedWIF: '6PYVHykkA1TfyQ2344wftv5e7vRoecV4iVwEVZ62aqCAx3dh3LDrRV19AS',
passphase: '123456'
};
// WIF <=> privateKey
