Question

I got a problem on my express server

app.get('/callback/:nation/:username/?:permalink', function(req, res)
            {
                nationurl = req.params.nation;
                username = req.params.username;
                storypermalink = req.params.permalink;


                console.log("nation: "+nation);
                console.log("username: "+username);
                console.log("permalink: "+permalink);
            });

Beacause of the /?: it split the username and doesn’t give my permalink :

nation: poneyclub
username: j
permalink: hondoe

Anybody have an idea ?

Answer 1

This is because ? is a special character in Express routing algorithm. See the documentation for details.

When you type URL Express treats everything after ? character as a query. It should be in a format

?key1=value1&key2=value2&...&keyX=valueX

and it can be retrieved using req.query.

You can change this default behaviour using your own regular expression in route (again see the documentation for details).
