用于 Express 中路由匹配的正则表达式 [英] Regex for route matching in Express

问题描述

我不太擅长正则表达式，所以我想确保我这样做是正确的.假设我有两条非常相似的路线，/discussion/:slug/ 和 /page/:slug/.我想创建一个匹配这两个页面的路由.

I'm not very good with regular expressions, so I want to make sure I'm doing this correctly. Let's say I have two very similar routes, /discussion/:slug/ and /page/:slug/. I want to create a route that matches both these pages.

app.get('/[discussion|page]/:slug', function(req, res, next) {
  ...enter code here...
})

这是正确的做法吗?现在我只是在创建两条独​​立的路线.

Is this the correct way to do it? Right now I'm just creating two separate routes.

someFunction = function(req, res, next) {..}
app.get('/discussion/:slug', someFunction)
app.get('/page/:slug', someFunction)

推荐答案

app.get('/:type(discussion|page)/:id', ...) 有效
