解析动态参数，获取信息

    1. export function getCategory(path) {
    2.   let current = 1;
    3.   if (!path) {
    4.     return { ids: [], id: undefined, current: 1 };
    5.   }
    7.   // 切分路径
    8.   const ids = path.split('/');
    10.   if (!ids|| !ids.length) {
    11.     return { ids: [], id: undefined, current: 1 };
    12.   }
    14.   let pageReg = /^p[0-9]+$/;
    15.   if (pageReg.test(ids[ids.length - 1])) {
    16.     const currentStr = ids[ids.length - 1].replace('p', '');
    17.     const parseCurrent = parseInt(currentStr);
    19.     current = parseCurrent > 0 ?parseCurrent : 1
    20.     return { ids:ids.slice(0,ids.length-1), id: ids[0, ids.length - 2], current };
    21.   }
    23.   return { ids, id: ids[ids.length - 1], current: 1 };
    24. }
