【刘杰良】使用RPC接口新建EOS账户 - 实战

适用于最新的 EOS Dawn 4.0/4.1

前言

最近在研究 EOS 的 RPC API,但是由于官方API文档的不够详尽,新建账号(new account)这一个操作就折腾了一个多星期。皇天不负有心人,终于调通了新建账号,代币转账也轻松解决。特地写这篇文章(适用于 EOS dawn 4.0 和 4.1),帮助准备使用 EOS RPC 做 Dapp 开发的朋友,如有问题,欢迎批评指正。

少废话,先看东西

1、POST http://127.0.0.1:8888/v1/chain/abi_json_to_bin (序列化新建账号的 json)

{
  "code": "eosio",
  "action": "newaccount",
  "args": {
    "creator": "bitcoin",
    "name": "eason",
    "owner": {
      "threshold": 1,
      "keys": [
        {
          "key": "EOS4ufZoTw95yHJS6Cyz3h4w5a2W4cyYpMYRnd7gbFZuCfPxUFS6r", //owner public key
          "weight": 1
        }
      ],
      "accounts": [],
      "waits": []
    },
    "active": {
      "threshold": 1,
      "keys": [
        {
          "key": "EOS4ufZoTw95yHJS6Cyz3h4w5a2W4cyYpMYRnd7gbFZuCfPxUFS6r", //active public key
          "weight": 1
        }
      ],
      "accounts": [],
      "waits": []
    }
  }
}

2、POST http://127.0.0.1:8888/v1/wallet/sign_transaction(签名新建账号的交易)

[
  {
    "ref_block_num": 363759,
    "ref_block_prefix": 4033496171,
    "expiration": "2018-05-17T09:54:06.500",
    "actions": [ { "account": "eosio", "name": "newaccount", "authorization": [ { "actor": "bitcoin", "permission": "active" } ], "data": "000000603a8ab23b000000ca3d364dfb0100000001000202aba1b7d9fc5de9dd93308dc5ebedcb066c8e5b36970bfd82ae715d9e8c3060010000000100000001000202aba1b7d9fc5de9dd93308dc5ebedcb066c8e5b36970bfd82ae715d9e8c306001000000" } ],
    "signatures": [] },
  [
    "EOS5wQ4HaFFDxyfc23dZNXUTGBHepM1vXGfr1vkfWHfRfvAMXP7VV"
  ],
  ""
]

3、http://127.0.0.1:8888/v1/chain/push_transaction (把签名后的交易push 推送到 EOS 系统中,即新建账号完成)

{
  "compression": "none",
  "transaction": { "expiration": "2018-05-17T09:54:06.500", "ref_block_num": 363759, "ref_block_prefix": 4033496171, "actions": [ { "account": "eosio", "name": "newaccount", "authorization": [ { "actor": "bitcoin", "permission": "active" } ], "data": "000000603a8ab23b000000ca3d364dfb0100000001000202aba1b7d9fc5de9dd93308dc5ebedcb066c8e5b36970bfd82ae715d9e8c3060010000000100000001000202aba1b7d9fc5de9dd93308dc5ebedcb066c8e5b36970bfd82ae715d9e8c306001000000" } ] },
  "signatures": ["SIG_K1_KY58QhP4jWLJWr7cVkahgL3JAjC8QMK5jnHurFUmn8xU71v6Mh4DmgjY75DxmWE6Je457N6MRM7GapxU43hywnAWKEmC1W"] }

(代币转账 和 新建账号的 sign_transaction、push_transaction 类似,主要就是 智能合约的不同 和 调用的action 的不同 以及 action 中具体的参数不同。)

新建账号(newaccount)需要用 「已有的账号」 创建「 新账号」

内部是 已有账号 调用系统智能合约eosio中的 newaccount 的 action

新建账号的交易需要用 创建者私钥签名交易(sign_transaction),然后 推送签名后的交易 (push_transaction)到区块链中。
