{message：“”，exception：“Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException”，...}

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:\Usersolan\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");

Ok so I'm not sure if this has anything to do with it, but it seems as though you may have incorrectly typed it into your question, but you have written:

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

Is it meant to say success: instead of succes:?

NotFoundHttpException usually means that your route doesn't exist. Check your web.php file and make sure that there is a route there for '/saveProduct' and that it is a post route and not a get route.

You will need a route like this:

Route::post('/saveProduct', 'adminInventoryController@saveProduct');
