如何让多条路线使用express.js中的同一条路线函数

Question

I can use

app.get('/:someVar/xxxxx', function(req, res) { /* etc */ });

to get someVar by req.params.someVar . However, I want both www.example.com/12345/xxxxx and www.example.com/xxxxx to go into the same app.get

How should I approach this problem?

Answer 1

Don't repeat yourself. Pass an array to express.js 's route method:

app.route(["/12345/xxxxx", "/xxxxx"])
   .get(function (req, res) { /* etc */ })

see app.route & app.get

Answer 2

Assign function to variable

var yourFunction = function (req, res) {
...
}

And you can use it afterwards as parameter passed to app.get()

app.get('/:someVar/xxxxx', yourFunction);
app.get('/xxxxx', yourFunction);
