Express.js route parameter with slashes
提问by Gerstmann
I have an application which serves file listings.
我有一个提供文件列表的应用程序。
The application must respond to following routes:
应用程序必须响应以下路由：
/company/:id
/company/:id/dir
/company/:id/dir/dir
Here /company/:idis a route with no pathspecified e.g a rootdirectory. I was thinking for something like app.get('/company/:id/:path', ...which obviously doesn't work.
这/company/:id是一个没有path指定的路由，例如一个root目录。我正在考虑类似的事情app.get('/company/:id/:path', ...，但显然行不通。
How can I define a route which responds to all of the examples?
如何定义响应所有示例的路由？

Use /company/:id*(note trailing asterisk).
使用/company/:id*（注意尾随星号）。
