javascript - jquery ajax - calling my asp.net web api gives a wrong url and a 404 not found message - Stack Overflow

I'm writing a small ASP.NET MVC site which also includes a WEB API in it that I wrote.

I've configured the project on my local IIS as http://localhost/mysite

On the main page of my site I'm including a js script that I wrote:

<script src="@Url.Content("~/Content/js/home.js")"></script>

on the page ready event of that js I call:

$.ajax({
    url: 'api/getdetails',
    accepts: 'application/json',
    cache: false,
    type: 'GET',
    success: function (data) {
        alert(data);
    }
});

when looking with Fidler I see that the page call returns a 404 since it doesn't try to load it to the relative path I'm in (http://localhost/mysite) and it tries to load the root of the server - so the call looks like this http://localhost:80/api/getdetails

when I was writing web forms I used to do ajax calls such as this all the time and it always worked.

what am I missing?

Thanks

• Web API is a REST based system. Try to dig a little deeper into REST and embrace its mindset. Naming the controller "GetDetails" is not restful and it's repetitive too. – timmkrause Commented Feb 2, 2014 at 10:00
• @timmkrause thanks - i'll take that into consideration - however, this is not what's causing the problem... – developer82 Commented Feb 2, 2014 at 10:03

What I ended up doing is in my layout html I've added a js var:

var baseUrl = '@Url.Content("~/")';

then on my ajax call I've added that base url:

$.ajax({
    url: baseUrl + 'api/getdetails',
    accepts: 'application/json',
    cache: false,
    type: 'GET',
    success: function (data) {
        alert(data);
    }
});

this does the trick no matter how the page looks like. even if I navigate to http://localhost/mysite/home/index

It's probably not the perfect solution, and I definitely think the old webforms way which worked was better - but I guess there are pros and cons to any technology.

Still would be happy to hear if someone has a better solution. for now - this does the trick.

When you navigate to

http://localhost/mysite

The behavior is a little different from

http://localhost/mysite/

Try that to confirm. Without the trailing slash, the "mysite" looks like a document name, not a folder, so relative paths would form from the root of the server.

What you may need to do is pass in the site content URL into your home.js and form absolute paths from it in your code.
