ASP.NET Core中的AJAX请求

I need to make requests back to my server in my web app, for example, the user clicks a table item and it loads extra data in another part of the same page.

So far I have been doing this via AJAX requests, which have been working fine (although if this is not the best practice way I would welcome any alternative suggestions).

The problem I found is that the requests no longer worked when I published the site to IIS. Looking into it I have found that the URL is missing something when called from IIS.

For example, in debug (localhost), I make my request like this:

await $.ajax({
    type: 'GET',
    url: 'products?handler=productid=' + productId});

...where 'products' is the name of the page I made the request from, for which the path is localhost/products.

When being hosted from IIS the url is now localhost/mynewapp/products, and so the base path has changed, which is why my requests don't work in IIS.

I've fixed this by adding the following JS method:

function GetBaseUrl() {
    var url = window.location;

    return url.pathname;
}

… and then changing the AJAX call to:

await $.ajax({
    type: 'GET',
    url: GetBaseUrl() + '?handler=productid=' + productId});

This works in both debug and IIS.

This just feels a bit hack-y to me, and so my question is, what is the proper way to deal with this situation?
