js 从路径获取参数

const getPathParams = (path, pathMap, serializer) => {
  path = path.split("/");
  pathMap = pathMap.split("/");
  return pathMap.reduce((acc, crr, i) => {
    if (crr[0] === ":") {
      const param = crr.substr(1);
      acc[param] = serializer && serializer[param]
        ? serializer[param](path[i])
        : path[i];
    }
    return acc;
  }, {});
};

getPathParams("/app/products/123", "/app/:page/:id");
// { page: 'products', id: '123' }

getPathParams("/items/2/id/8583212", "/items/:category/id/:id", {
  category: v => ['Car', 'Mobile', 'Home'][v],
  id: v => +v
});
// { category: 'Home', id: 8583212 }
