使用Redux从最新日期返回JSON响应中的行或每个对象

Question

我有来自GET请求的JSON响应，格式如下所示。我想过滤并显示最新日期（更新日期）的条目。有多个条目具有相同的＆＃39; PK＆＃39;。在这种情况下，我只想显示最后一个日期。我想要一个提供这种结果的过滤功能。代码正在反应中。我试图在传递组件之前在reducer中过滤掉它。

我的行动：

export const trackingInfoFetchDataSuccess = trackingId => {
  return {
    type: TRACKINGINFO_FETCH_DATA_SUCCESS,
    payload: trackingId
  };
}

//获取功能

export const trackingInfoFetchData= url => {
   return (dispatch) => {
       dispatch(trackingInfoIsLoading(true));
       const myData = myObject;
        fetch(url)
       .then((response) => {
           if (!response.ok) {
               throw Error(response.statusText);
           }
           dispatch(trackingInfoIsLoading(false));
           console.log(response);
           return response;
       })
       .then((response) => response.json())
       .then((items) => dispatch(trackingInfoFetchDataSuccess(items)))
       .catch(() => dispatch(trackingInfoHasErrored(true)));
   };
}

我的减速机：

export function trackingInformation(state = [], action) {
    switch (action.type) {
        case TRACKINGINFO_FETCH_DATA_SUCCESS:
       //Map or any filtering needs to be added here
            return action.payload;

        default:
            return state;
    }
}

JSON键被修改为仅提供我想要实现的内容的一个示例

一旦数据被过滤，我只会在表格中显示带有最新日期的条目，而不是将JSON响应中的所有条目显示在表格中。

我正在使用React-Bootstrap-table进行表示。

现在我在表格中显示整个JSON。
