FIBOS 事务 Transactions 解码知识

Transaction 的 hex_data 解码

举个例子,来解码 eosio.token/excreate:

交易地址

关键数据:

 {
  "account": "eosio.token",
  "name": "excreate",
  "authorization": [{
    "actor": "tstmwasd1234",
    "permission": "active"
  }],
  "data": {
    "issuer": "tstmwasd1234",
    "maximum_supply": "1000.0000 GWW",
    "connector_weight": "0.33000000000000002",
    "maximum_exchange": "500.0000 GWW",
    "reserve_supply": "50.0000 GWW",
    "reserve_connector_balance": "40.0000 FO",
    "expiration": "2018-11-16T15:00:00"
  },
  "hex_data": "408608091b2e33ce809698000000000004475757000000001f85eb51b81ed53f404b4c0000000000044757570000000020a10700000000000447575700000000801a06000000000004464f000000000070dbee5b"
 }

开始解码:

const FIBOS = require("fibos.js");
const fibos = FIBOS();
let rawdata = FIBOS.modules.Fcbuffer.fromBuffer(fibos.fc.structs.excreate, Buffer.from(hex_data, 'hex'));
console.log(rawdata);

输出结果:

{
  "issuer": "tstmwasd1234",
  "maximum_supply": "1000.0000 GWW",
  "connector_weight": 0.33,
  "maximum_exchange": "500.0000 GWW",
  "reserve_supply": "50.0000 GWW",
  "reserve_connector_balance": "40.0000 FO",
  "expiration": "2018-11-16T15:00:00"
}

解析过程：

ctx.fc.structs.excreate 是 excreate 的 ABI action 参数类型

{
	"base": "",
	"action": {
		"name": "excreate",
		"account": "eosio.token"
	},
	"fields": {
		"issuer": "account_name",
		"maximum_supply": "asset",
		"connector_weight": "float64",
		"maximum_exchange": "asset",
		"reserve_supply": "asset",
		"reserve_connector_balance": "asset",
		"expiration": "time_point_sec"
	}
}
