使用eosjs的对象API

使用require或import引入eosjs包中的主要类。例如，下面的nodejs代码使用require引入eosjs：

//引入eosjs
let {PrivateKey, PublicKey, Signature, Aes, key_utils, config} = require('eosjs-ecc')

//创建随机私钥
let privateWif
PrivateKey.randomKey().then(privateKey => privateWif = privateKey.toWif())

//由私钥推导出公钥
pubkey = PrivateKey.fromString(privateWif).toPublic().toString()

eosjs中主要的类如下：

PrivateKey
PublicKey
Signature
Aes
key_utils
config
