express / node.js-如何将路由参数传递给其他文件？

Question

Encountered a strange bug where if I have a route defined like so in routes/posts/index.js:

router.use('/:id/edit', require('./edit'));

Inside ./edit, I have the endpoint defined like so:

router.post('/', passport.authenticate('jwt', { session: false}), function(req, res){

If I hit /posts/:id/edit, I successfully hit the endpoint in ./edit, but const id = req.params.id; will be undefined. However, if I define the route directly in routes/posts/index.js, req.params.id will be defined.

What is the correct way for letting the route in ./edit 'recognize' the id parameter?

您可以通过将{mergeParams: true}传递给express.Router()来合并父路由器参数。
