exchanges[0].SetContractType(leixing_bitmex);
其中，leixing_bitmex 为外部参数，定义为str XBTUSD
可是，定义合约类型后，返回了true ，但是获取深度时总是反馈 Your browser sent an invalid request.
如果直接用exchanges[0].SetContractType('XBTUSD'); 就一切正常，难道合约类型不能用外部参数传递吗？
求教

Python 语言 还是 JS ， 如果是python 注意 全局变量 作用域 ， 局部 有没有 重名的变量 等问题。
在这句 exchanges[0].SetContractType(leixing_bitmex); 设置合约之前， Log 一下leixing_bitmex 变量，确定一下是不是 XBTUSD 。
