具体什么错误，api出问题是非常常见的错误

function kaiduo(symbol, PRI, shoushu) { var duodan = exchange.IO("api", "POST", "/fapi/v1/order", "symbol=" + symbol + "&side=BUY&type=LIMIT&quantity=" + shoushu + "&price=" + PRI + "&timeInForce=GTC&timestamp=_D") while (duodan == null) { Log('30下单失败,出错!!'); duodan = exchange.IO("api", "POST", "/fapi/v1/order", "symbol=" + symbol + "&side=BUY&type=LIMIT&quantity=" + shoushu + "&price=" + PRI + "&timeInForce=GTC&timestamp=_D"); } B_orders.push(duodan.orderId) return B_orders } 上面是下单的语句，但是到后面用订单ID查询订单的时候返回错误。下面是查询的函数。而且运行几个小时都没问题，只要出问题，今天剩下的时间就肯定一直不好用 for (i = 0; i < B_orders.length; i++) { Sleep(100) var B_ordered = exchange.IO("api", "GET", "/fapi/v1/order", "symbol=" + duofang + "&orderId=" + B_orders[i] + "&timestamp=_D") while (B_ordered == null) { Log('71查单失败,出错!!'); B_ordered = exchange.IO("api", "GET", "/fapi/v1/order", "symbol=" + duofang + "&orderId=" + B_orders[i] + "&timestamp=_D") }
