error 405 method not allowed

permisi saya mau tanya mengatasi error

GET http://konter.data:8080/barang/cari 405 (Method Not Allowed)

ini fungsi di controller

    public function caribarang(Request $request){
        $data = DB::table('barang')->where('nama', 'LIKE', '%'.$request->cari.'%')->OrderbyDesc('id')->simplepaginate(10);
        $total = DB::table('barang')->count();
        return view('barang', compact('data'), ['total' => $total]);
    }

ini ajaxnya

    $('#tombolcari').click(function(){
        var data = $('#cari').val();
        $.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
             }
        });
        $.ajax({
            type: 'post',
            data: data,
            url: '/barang/cari',
            success: function(){
                $('#konten').load('/barang/cari');
            }
        });
    });
