Passing a URL as a parameter to Node/Express app

Question

I have a simple Node/Express route, as follows:

var app = express();

app.get('gettags/:page', function(request,response)
{
    var thePage = request.params.page;
    ...
    ...
}

The problem I'm having is that if I pass a URL as the parameter, I get a "Cannot GET" error. So, if I call this like:

http://www.mynodeapp.com/gettags/http://www.someurl.com/?withquery=something

I get the "Cannot GET" error. It's been a couple years since I've used Node, so I am probably forgetting something very basic. But I can't get past this, and Googling this issue hasn't turned up anything useful.

Thanks for any help!

Answer 1

Your node code looks fine but for this to work you'll need to URI encode your argument:

var url = 'http://www.mynodeapp.com/gettags/' + encodeURIComponent('http://www.someurl.com/?withquery=something')

//becomes: http://www.mynodeapp.com/gettags/http%3A%2F%2Fwww.someurl.com%2F%3Fwithquery%3Dsomething

Answer 2

The Problem in your code is

/ 's of http://www.someurl.com

so to overcome this use url encoding functions in node such as

encodeURIComponent("Your url goes here")
