发送订单
第1 发单 cover_vt_orderid = self.cover(cover_price, abs(order_volume))
发单之后INFO信息会返回一个Order Object
第2 打印 self.write_log(f'买入平仓 , pos:{self.pos}, local_pos:{self.local_pos}, \
orderid:{cover_vt_orderid}, symbol:{self.vt_symbol}, price:{cover_price}, volume:{order_volume}')
返回信息 和打印信息如下：

2021-07-02 09:03:05,617 INFO: ex_long jm2108&jm2110: 买入平仓 , pos:50, local_pos:0, orderid:['CTP.6_1679360163_1'], symbol:SP jm2108&jm2110.DCE, price:116.5, volume:1请问，怎么才能第一时间在策略的内部主动获取这个Order Object的信息
cover_vt_orderid = self.cover(cover_price, abs(order_volume))
譬如在上述发单命令之后，在策略的内部调用self.cta_engine.main_engine.get_order(cover_vt_orderid)，获取不到这个order Object，得到的是 None
