重定向express.js中的多个路由

Question

I am working on an express app and am new to the framework. I have a few routes I'd like to redirect to one without doing something like:

var router = require("express").Router();

router.all("/route", function(req, res){
    res.redirect("/repetitive");
});

router.all("/route2", function(req, res){
    res.redirect("/repetitive");
});

This is a contrived example, but I'm looking for a way to have many routes redirect to /repetitive without writing lots of router.all s , but I don't see a way in the docs. Is passing a regex to router.all an option and if so is that the best practice for express? Thanks!

Answer 1

What about the following?

var r = function(req, res) {
    res.redirect("/repetitive");
}

var routes = ["/route", "/route2"];
for (var i in routes)
    router.all(routes[i], r);

or if names follow a regular expression pattern:

router.all(/\/route\d*/, function(req, res) {
    res.redirect("/repetitive");
});

The above will match "/route" optionally followed by a number.
