How to receive a value in a variable sent from the client with ajax in a URL in nodejs?

I have a URL which I want to send to the server with ajax in order to delete products based on id. How can I receive that with NodeJS just as I would do this in the PHP api so : 

$sProductId = $_GET['id'];

This is the URL from the ajax call:

var sUrl = "/delete-product" + sProductId;

This is my server.js

app.post('/delete-product' ???, upload.none(), (req, res) => {
        global.sUpdateProductImagePath = req.file.path.split("public/")[req.file.path.split("public").length - 1]
        user.deleteProduct(req.body, (err, jResult) => {
            if (err) {
                console.log(jResult)
                return res.send(jResult)
            }
            console.log(jResult)
            return res.send(jResult)

        })
    })

And my user.js:

user.deleteProduct = (jProductData, fCallback) => {
    global.db.collection('products').deleteOne({ "_id": "" }, (err, jResult) => {
        if (err) {
            var jError = { "status": "error", "message": "ERROR -> deleteProduct -> user.js -> 001" }
            return fCallback(false, jError)
        }
        var jOk = { "status": "ok", "message": "user.js -> product deleted -> 000" }
        console.log(jResult)
        return fCallback(false, jOk)
    })
}

you can do like this if you want id in path params

app.post('/delete-product/:id', upload.none(), (req, res) => {var id= req.params.id; // this id is from path params

you can also send id in search query like /delete-product?id=yourid

 app.post('/delete-product', upload.none(), (req, res) => {var id= req.query.id;

The way you are passing the parameters to send it from the client to the server is a get method. The id is part of the url.

So, in the server you should change the post for get and add /:idproduct to receive it.

Also, instead of req.body, you should change to req.params.:

For example:

app.get('/delete-product/:idproduct', (req, res) => {

    //global.sUpdateProductImagePath = req.file.path.split("public/")[req.file.path.split("public").length - 1]
    //req.body = req.params.idproduct
    user.deleteProduct(req.params.idproduct, (err, jResult) => {
        if (err) {
            console.log(jResult)
            return res.send(jResult)
        }
        console.log(jResult)
        return res.send(jResult)

    })
})
