推荐答案

假设 ExpressJS，你应该不需要通过它.

Assuming ExpressJS, you shouldn't need to pass it.

对于每个参数占位符(如 :id)，req.params 应该有一个匹配的属性来保存值:

For each parameter placeholder (like :id), req.params should have a matching property holding the value:

exports.dashboard = function (req, res) {
    console.log(req.params.id);
};

不过，这假设请求的 URL 与动词和模式匹配的路由.

Though, this assumes the requested URL matches the route by verb and pattern.
