I'm a newbie in laravel. I want to add a product using ajax method but I'm getting this error, in the console: `POST 404 NOT FOUND`. In the network, I'm getting this error message:

```
{message: "", exception: "Symfony\Component\HttpKernel\Exception\NotFoundHttpException",…}
exception: "Symfony\Component\HttpKernel\Exception\NotFoundHttpException"
file: "C:\Users\rolan\Desktop\Laravel Tutorial\Fims\vendor\laravel\framework\src\Illuminate\Routing\RouteCollection.php"
line: 179
message: ""
trace: [{,…}, {,…}, {,…}, {,…}, {,…},…]

```

Here is my ajax code: 

```
<script>
$(document).ready(function(){
    // alert("working");
    $("#btn").click(function(){
        var prodName = $("#prodName").val();
        var rate = $("#rate").val();
        var beginningQuantity = $("#beginningQuantity").val();
        var token = $("#token").val();

        $.ajax({
            type: "POST",
            data: "prodName=" + prodName + "&rate=" + rate + "&beginningQuantity=" + beginningQuantity + "&_token" + token,
            url: "<?php echo url('/saveProduct') ?>",
            success: function(data){
                console.log(data);
            }
        });
    });
});
</script>

```

here's the line 179 codes

```
<input type="hidden" value="{{csrf_token()}}" id="token">

```

here's the controller code

```
public function saveProduct(Request $request){
    return $request;
}

```

here's the route

```
Route::get('/adminIndex',"adminIndexController@count");
Route::get('/adminInventory',"adminInventoryController@count");

```
