Bitshares Python库的文档并没有写如果在一个tx中下多个单的方法，经过看源码，找到了方法。
现总结下代码
from bitshares import BitShares
from bitshares.market import Market
from bitshares.asset import Asset
from bitshares.account import Account
from bitshares.utils import formatTimeFromNow
from bitsharesbase import transactions, memo, account, operations, objects
API_URL = 'ws://127.0.0.1:8090/ws'
PRIV_KEY = '这是账号私钥'
ACCOUNT_NAME = 'ety001'
# 创建连接
bitshares = BitShares(API_URL, keys=PRIV_KEY)
# 创建账号实体
importAccount = Account(ACCOUNT_NAME, blockchain_instance=bitshares)
# 拿到 orderbook
market = Market('BTS:CNY', blockchain_instance=bitshares)
orderbook = market.orderbook(1)
sellAssetId = orderbook['bids'][0]['quote']['asset']['id']
receiveAssetId = orderbook['bids'][0]['base']['asset']['id']
amountToSell = 3 * 10 ** orderbook['bids'][0]['quote']['asset']['precision']
receiveAmount = 5 * 10 ** orderbook['bids'][0]['base']['asset']['precision']
# 创建订单
op1 = operations.Limit_order_create(
**{
"fee": {"amount": 0, "asset_id": "1.3.0"},
"seller": importAccount['id'],
"amount_to_sell": {
"amount": int(round(amountToSell)),
"asset_id": sellAssetId,
},
"min_to_receive": {
'amount': int(round(receiveAmount)),
"asset_id": receiveAssetId,
},
"expiration": formatTimeFromNow(60 * 60 * 24 * 7),
"fill_or_kill": True,
"extensions": [],
}
)
op2 = operations.Limit_order_create(
**{
"fee": {"amount": 0, "asset_id": "1.3.0"},
"seller": importAccount['id'],
"amount_to_sell": {
"amount": int(round(amountToSell)),
"asset_id": sellAssetId,
},
"min_to_receive": {
'amount': int(round(receiveAmount)),
"asset_id": receiveAssetId,
},
"expiration": formatTimeFromNow(60 * 60 * 24 * 7),
"fill_or_kill": True,
"extensions": [],
}
)
opList = []
opList.append(op1)
opList.append(op2)
# 下单
bitshares.finalizeOp(opList, ACCOUNT_NAME, 'active')
说明：
- 需要连接获取数据的方法，请使用参数
blockchain_instance把你自己创建的对象传入，
否则连接的API并不是你指定的。默认连接库作者的API。- 买入卖出数量需要转换成整数，即乘以
precision
