SteemJs注册的两种方法 / 网络研习社#56

参考steemsnippets |　创建免费用户 |　Claiming a discounted ("free") account |　创建用户

这两天在社区中查找了SteemJs用户注册的实现方法，还好，测试了下，也都实现了！Steem在原有的基础上提供了一种新的免费注册的方法（discounted_account），这种新方法可以比较快速地完成新用户注册。

SteemJs注册主要有两种方法：一是create_discounted_account，另一个是accountCreate。create_discounted_account是用消耗RC注册，一个新号需要约10,445,334,023,565 RC，SP大户才能玩得转。像我的帐户（lemooljiang）一天也只能注册２～３个。accountCreate就是付费注册(3个steem)，其它的就没什么限制了。

create_discounted_account

如上图所示。

这个是用dsteem来完成注册功能，有两步，一步是申明帐户(claim_account)，使其处于Pending状态；第二步是就是直接注册了(create_discounted_account)。

1. 安装和挂载

cnpm install dsteem --save
//main.js
const dsteem = require('dsteem')
const client = new dsteem.Client('https://api.steemit.com')
Vue.prototype.dsteem = dsteem
Vue.prototype.client = client

1. 两个注册函数

claim_account() {
  const creator = "lemooljiang"　　//创建帐户的用户名
  const active_key = "5Jffffffffff"　//创建帐户的资金密钥
  return new Promise(resolve => {
      const wif = this.dsteem.PrivateKey.fromString(active_key)
      const fee = this.dsteem.Asset.from(0, 'STEEM')
      const op = [
          'claim_account',
          {
              creator: creator,
              extensions: [],
              fee: fee
          }]

      this.client.broadcast.sendOperations([op], wif).then(function (result) {
          console.log('11,Included in block: ' + result.block_num)
          console.log('222，申明新帐户创建成功！' )
          resolve("ok")
      }, function (error) {
        console.error(error)
        console.log('333，申明新帐户创建失败！' )
        resolve("err")
      })
  })
},
create_discounted_account() {
  const creator = "lemooljiang"　　//创建帐户的用户名
  const active_key = "5Jofffffffffffff"　//创建帐户的资金密钥
  const username = this.username　　//新帐户名
  const password = this.password　　//新帐户的密码
  return new Promise(resolve => {
      const wif = this.dsteem.PrivateKey.fromString(active_key)
      const prefix = this.client.addressPrefix
      const ownerKey = this.dsteem.PrivateKey.fromLogin(username, password, 'owner').createPublic(prefix)
      let owner = this.dsteem.Authority.from(ownerKey)
      const activeKey = this.dsteem.PrivateKey.fromLogin(username, password, 'active').createPublic(prefix)
      let active = this.dsteem.Authority.from(activeKey)
      const postingKey = this.dsteem.PrivateKey.fromLogin(username, password, 'posting').createPublic(prefix)
      let posting = this.dsteem.Authority.from(postingKey)
      let memo_key = this.dsteem.PrivateKey.fromLogin(username, password, 'memo').createPublic(prefix)

      const metadata =  {date: new Date()}
      const create_op = [
          'create_claimed_account',
          {
              active,
              creator,
              extensions: [],
              json_metadata: metadata ? JSON.stringify(metadata) : '',
              memo_key,
              new_account_name: username,
              owner,
              posting,
          }
      ]

      this.client.broadcast.sendOperations([create_op], wif).then(function (result) {
          console.log('22, Included in block: ' + result.block_num)
          console.log('666，新帐户创建成功！' )
          resolve("ok")
      }, function (error) {
          console.log('444，新帐户创建失败！' )
          console.error(error)
          resolve("err")
      })
  })
},

accountCreate

这种方法简单直接，付点小费创建就可以啦。

它主要由steem的两个方法来实现：steem.auth.generateKeys 用于生成4组密钥(owner, active, posting, memo)，steem.broadcast.accountCreate 用于创建账号。

npm install steem --save
//main.js
import steem from 'steem'
steem.api.setOptions({ url: 'https://api.steemit.com' })
Vue.prototype.steem= steem

register() {
  let newAccountName = "bettyliu"　　//新帐户名
  let newAccountPassword = "FDJUJUJUJU"　　//新帐户的密码
  let publicKeys = this.steem.auth.generateKeys(newAccountName, newAccountPassword, ['owner', 'active', 'posting', 'memo'])
  let owner = { weight_threshold: 1, account_auths: [], key_auths: [[publicKeys.owner, 1]] }
  let active = { weight_threshold: 1, account_auths: [], key_auths: [[publicKeys.active, 1]] }
  let posting = { weight_threshold: 1, account_auths: [], key_auths: [[publicKeys.posting, 1]] }
  let memoKey = publicKeys.memo

  let creator = "lemooljiang"　//创建帐户的用户名
  let creatorWif = "5Jffffffffffff"　//创建帐户的资金密钥
  let fee = "3.000 STEEM"　//手续费
  let jsonMetadata = ""
  this.steem.broadcast.accountCreate(
      creatorWif,
      fee,
      creator,
      newAccountName,
      owner,
      active,
      posting,
      memoKey,
      jsonMetadata,
      (err, result) => {
        if(err){
          console.log(444, '创建失败！', err)
        }else{
          console.log(666, '创建成功！', result)
        }
      })
}
