Cascader 级联选择器获取选中的label值得问题，2.7.2版本可以通过this.$refs['cascaderAddr'].currentLabels方法获取，更新后该方法失效。

Cascader cascade selector to get the selected label is worth the problem. Version 2.7.2 can be obtained by this. $refs ['cascader Addr']. CurrtLabels method, which is invalid after updating.

currentLabels is not public api, u can use getCheckedNodes to get the checked labels.
