7月15日，下午无法得到数据

[lmf-zr]

client = TdxHqClient()

自动选择可用服务器 (推荐)!!!important

client.connect_to_any()
markets = MARKET_SH if market == "sh" else MARKET_SZ
df = client.get_security_bars_dataframe(KLINE_DAILY, markets, code, 0, 200, FQ_QFQ)
print(df)
client.disconnect() # Important to disconnect

输入如下：
Empty DataFrame
Columns: [datetime, year, month, day, hour, minute, open, high, low, close, vol, amount]
Index: []

上午还在用。这会封IP么？

[jiangtaovan]

公共服务器不存在封ip的问题。但已知的服务器策略是，对频繁请求，可能存在返回错误数据或空数据。当前已设定默认的请求频率限制。请确认一下是否请求过于频繁，建议适当调整一下客户端的调用策略。最好是编程可控的，不是skill或claw类的请求。

[jiangtaovan]

已更新服务器的优先逻辑，尝试升级0.6.6版本，看是否已经解决问题。

用库内范例，输出还是空。

from tdxrs import TdxHqClient
from tdxrs.constants import MARKET_SH, KLINE_DAILY, FQ_QFQ

client = TdxHqClient()
client.connect_to_any()

df = client.get_security_bars_dataframe(KLINE_DAILY, MARKET_SH, "600519", 0, 500)
df["ma20"] = df["close"].rolling(20).mean()

quotes = client.get_security_quotes([
(MARKET_SH, "600519"), (0, "000858"), (0, "300750")
])
print(df)
print(quotes)
client.disconnect()

输出：
Empty DataFrame
Columns: [datetime, year, month, day, hour, minute, open, high, low, close, vol, amount, ma20]
Index: []
[]

最不可思议的是：

client.connect("180.153.18.170", 7709)
可以用。
