我在您的项目里看到 dao.fetchLocalData(date).then((localData) => { //Toast.show('local', {position: px2dp(-80)}); dispatch(receiveData(localData, date)); }, (localData) => { //Toast.show('local', {position: px2dp(-80)}); dispatch(onlyFetchLocalData(getYesterdayFromDate(date))); }); 其中 (localData)有2个，这在代码中怎么执行的，谢谢。

这个是Promise，前面是resolve返回的值，后面是reject返回的值。后一个localData其实没有当作参数使用。这两个参数名字可以随便起
