如题
希望通过切换 exchange = exchanges[i] 达到可以获取不同ListenKey的目的
exchange.IO("api", "POST", "/api/v3/userDataStream")
通过测试，同一个策略下的不同平台，不管exchange如何赋值，返回的key值都是一样的，是否可以认为，交易所并没有切换过去。
请问，这个要如何实现？

function getListenKey(exchangeIndex) {
var e = exchanges[exchangeIndex]
var key = e.IO("api", "POST", "/api/v3/userDataStream")
Log(key)
return key
}
function main() {
var key0 = getListenKey(0)
var key1 = getListenKey(1)
}
是这个意思吗？
