使用RPC介面新建EOS賬戶 - 實戰
阿新 • • 發佈：2019-01-01
前言
最近在研究 EOS 的 RPC API，但是由於官方API文件的不夠詳盡，新建賬號（new account）這一個操作就折騰了一個多星期。皇天不負有心人，終於調通了新建賬號，代幣轉賬也輕鬆解決。特地寫這篇文章（適用於 EOS dawn 4.0 和 4.1），幫助準備使用 EOS RPC 做 Dapp 開發的朋友，如有問題，歡迎批評指正。
少廢話，先看東西
1、POST http://127.0.0.1:8888/v1/chain/abi_json_to_bin （序列化新建賬號的 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（簽名新建賬號的交易）
[ { "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 （把簽名後的交易push 推送到 EOS 系統中，即新建賬號完成）
{ "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"] }
(代幣轉賬 和 新建賬號的 sign_transaction、push_transaction 類似，主要就是 智慧合約的不同 和 呼叫的action 的不同 以及 action 中具體的引數不同。)
新建賬號（newaccount）需要用 「已有的賬號」 建立「 新賬號」
內部是 已有賬號 呼叫系統智慧合約eosio中的 newaccount 的 action
新建賬號的交易需要用 建立者 的 私鑰簽名交易（sign_transaction），然後 推送簽名後的交易 (push_transaction)到區塊鏈中。
