Node.js - Express special characters in routes (/campañas)

Question

I have a problem trying to set a route in Node JS with Express framework.

My route is this one:

app.get(\'/campaña/nueva\', sms.nueva);

Answer 1

I think you'll need to handle both a URL-encoded and perhaps a UTF-8 (and possibly Latin-1 also) variant. Check the following:

1. How are your clients (browsers) sending the URL?

   • URL encoded as %C3%B1 ?
     • chrome and firefox send the %C3%B1 encoding
     • I would presume this is the dominant and compliant behavior
   • Unicode ?
     • I tested with curl and it looks to send a single character which I presume is just whatever encoding it got from my terminal, which is probably UTF-8.

2. Based on that, try adjusting your route. You could use a regex or an explicit list

.

app.get('/campaña/nueva', sms.nueva)
app.get('/campa%c3%b1a/nueva', sms.nueva)
//Or for convenience if you like
app.get('/' + encodeURIComponent('campaña') + '/nueva', sms.nueva) 

My guess is ultimately most browsers are going to send the URL-encoded versions, so you can probably get by with just that last version.

Answer 2

I ran into the same problem with $ in my route. URL encoded character doesn't work in my case, but escaped one works.

So I ended up with

app.get('/\\$myRoute', function (req, res) {

}
