快速嵌套路由器不调用子功能

Question

我的其中一台路由器中有以下 router.use 调用router.use("/:collection/", (req) => {    return require(`./${req.params.collection}`);});在这个例子中调用，example.jsexample.js 如下：const header = require("../../header"); //gets our header that declares everythingconst router = header.express.Router(); //makes our router for collections requestsconsole.log("123");///The Following is when a name is requestedrouter.get("/test", (req, res, next) => {    console.log("test");    res.json({msg:"hi"});    next();});module.exports = router; //makes our router avialable你会期望什么时候：http://localhost:3000/api/example/test请求它会在控制台中写入以下内容：123test我会得到回应：{msg:"hi"}相反，控制台只得到：123写了，没有回应。看来 router.get在 example.js 中从未被调用，有人能告诉我为什么吗？

我修复了它，而不是

router.use("/:collection/", (req) => {

    return require(`./${req.params.collection}`);

});

我用

router.get("/:collection", (req, res) => {

  //this is my other call that will do stuff in the parent file

  //we don't call next because it is already matched, otherwise we call next

});

router.use("/:collection/", (req, res, next) =>{ //says if it gets here pass on the info

  router.use("/:collection/", require(`./${req.params.collection}`)); //then route

  next();

});
