My controller code is,

public function getPublicAttraction(Request $request)
    {
        return response(['msg'=>'success']);
    }

The ajax call,

<script>
    function getAttraction()
    {

        var pass= {'_token':$('meta[name="csrf-token"]').attr('content')

    };
    $.ajax({
            type:'POST',
            url:'{{route("Attractions")}}',
            datatype:'json',
            data: pass,
            success:function(data){
                $("#public_attractions").html(data.msg);
            }
        }).fail(function(jqXHR, textStatus, error){
            $("#public_attractions").html(jqXHR.responseText);
        });


    }
    $(document).ready(function(){
         getAttraction();
    });
</script>

meta tag with csrf token,

<meta name="csrf-token" content="!!{csrf_token()}!!">

the route file web.php entry,

Route::post('/getAttractions','AjaxController@getPublicAttraction')->name('Attractions');

I think I am stuck, please help.

Ok, everything looks fine except the way that the CSRF meta tag, Because you don't need to escape anything in the csrf token, so the correct way to print the token will be: <!-- CSRF Token --> <meta name="csrf-token" content="{{ csrf_token() }}"> This is the best guess i cant give you, because you do not provide what are the HTTP status of the response, neither which situation the exception is thrown, The exception message is also empty so ..

Why you reinvent something which is working fine.

1st Token in blade should look like this: (you have additional !! for what ever reason)

<meta name="csrf-token" content="{{ csrf_token() }}">

2nd Put this code somewhere in the master blade:

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
