IO与Http.Query查询OKex历史K线问题

Author: 小野, Created: 2021-12-16 15:59:09, Updated:

你好,想问一下,为什么用exchange.IO("api", “GET”, “/api/v5/market/history-candles”, “instId=BTC-USDT&before=1639467042705&after=1639467642705”);查不出数据,而使用HttpQuery(“https://www.okex.com/api/v5/market/history-candles?instId=BTC-USDT&before=1639467042705&after=1639467642705”)却可以查出数据 img
