Kucoin API“无效的KC-API-SIGN”

应为： req = requests.request（'POST'， url=url， headers=headers， data=order_json）.json（）

这对我来说也是一个令人头疼的问题。这是我当前（工作）期货API的代码：如何获取账户信息，如何开仓，如何平仓。

关于KC_place_order（curr、side、amount）的澄清： *参数 'curr' 是指您正在使用的交易对：例如，字符串值如 'FTM-USDT'、'ETH-USDT' 等。 *'side' 是多头或空头头寸的字符串值：例如 'buy' 或 'sell' *“金额”是您喜欢交易的货币数量的浮动值。

我知道，代码并不完美，但它正在工作。顺便说一句，现货 API 的代码会略有不同：问我是否有人也希望我发布它。

祝你好运！=)
