Using multiple parameters in URL in express

I am using Express with Node and I have a requirement in which the user can request the URL as: http://myhost/fruit/apple/red.

Such a request will return a JSON response.

The JSON data, before the above call looks like:

{
    "fruit": {
        "apple": "foo"
    }
}  

With the above request, the response JSON data should be:

{
    "apple": "foo",
    "color": "red"
}

I have configured express to route as follows:

app.get('/fruit/:fruitName/:fruitColor', function(request, response) {
    /*return the response JSON data as above using request.params.fruitName and 
request.params.fruitColor to fetch the fruit apple and update its color to red*/
    });  

But this does not work. I am unsure of how to pass multiple parameters, that is, I am unsure if /fruit/:fruitName/:fruitColor is the correct way to do this. Is it?

Solution 1:

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

Solution 2:

For what you want I would've used

    app.get('/fruit/:fruitName&:fruitColor', function(request, response) {
       const name = request.params.fruitName 
       const color = request.params.fruitColor 
    });

or better yet

    app.get('/fruit/:fruit', function(request, response) {
       const fruit = request.params.fruit
       console.log(fruit)
    });

where fruit is a object. So in the client app you just call

https://mydomain.dm/fruit/{"name":"My fruit name", "color":"The color of the fruit"}

and as a response you should see:

    //  client side response
    // { name: My fruit name, color:The color of the fruit}

Solution 3:

Both of the way is correct you can use any of them First way

app.get('/fruit/:one/:two', function(req, res) {
    console.log(req.params.one, req.params.two)
});

Another way using & symbol

app.get('/fruit/:one&:two', function(req, res) {
    console.log(req.params.one, req.params.two)
});
