UUOS API 接口概述

导入uuosapi模块

from uuoskit import uuosapi

create_key

创建一个新的密码对

uuosapi.create_key()

返回值

{

    'private':'5J6NzFGPDJDFzaiRzezeJwvNHomY91oaDYnQT8kraKUPm6y1bZ5'
}

create_account

创建一个新的账户创建账户前，要确定owner key和active key的私钥已经导入钱包，再使用对应的公钥创建账户

#需要先导入wallet
#操作前要执行wallet.import_key(wallet_name,private_key)
uuosapi.create_account('eosio',account_name,owner_public_key,active_public_key)
