不得不说，提前定义options这种方式很优雅，让我领教了。
另外在execute方法前的装饰器@exception的作用是什么？是可以省略try-exception的情况下自动抛出异常么？options = {"enabled": False, "group": "cmd.id", "keepEval": True} self._tris = { "id_here" : Trigger(self.session, r"^[> ]*你身上携带物品的别称如下|^[> ]*在这个房间中, 生物及物品的\(英文\)名称如下.*", onSuccess = self.id_here, **options), "id_item" : Trigger(self.session, r"^[> ]*([\u4e00-\u9fa5 ]+)\s+ = (.+)$", onSuccess = self.id_item, **options), "stop" : Trigger(self.session, r"^[> ]*系统回馈：id_is_over = 1", onSuccess = self.stop, **options), }
