该路由不支持GET方法。支持的方法：插入数据时进行开机自检

Question

我刚刚尝试使用ajax json插入数据，但出现了这样的错误。我检查了控制器，路线和型号。设置没有错。请帮忙。

对于View Blade

  function add() {
        save_method = 'add';
        $('#form_jabatan')[0].reset(); // reset form on modals
        $('#modal_form').modal('show'); // show bootstrap modal
        $('[name="kode"]').prop("readonly", false);
    }
    function save() {
        var url = "";
        if (save_method === 'add') {
            url = "<?php echo url('/simpanjabatan') ?>";
        } else {
            url = "<?php echo url('/simpanjabatan') ?>";
        }
        $.ajax({
            url: url,
            type: "POST",
            data: $('#form_jabatan').serialize(),
            dataType: "JSON",
            success: function (data) {
                if (data.errors) {
                    jQuery.each(data.errors, function (key, value) {
                        jQuery('.alert-danger').show();
                        jQuery('.alert-danger').append('<p>' + value + '</p>');
                    });
                } else {
                    alert(data.status);
                    $('#modal_form').modal('hide');
                    reloadpage();
                }
            },
            error: function (request, status, error) {
                alert("Error json " + error);
                json = $.parseJSON(request.responseText);
                $.each(json.errors, function (key, value) {
                    $('.alert-danger').show("");
                    $('.alert-danger').append('<p>' + value + '</p>');
                });
            }
        });
    }

对于控制器

 public function simpanjabatan(Request $req)
{
    $obj = new DetailJabatanModel();
    $obj->id_jabatan = $req->input('kode');
    $obj->jabatan = $req->input('jabatan');
    $obj->gaji_pokok = $req->input('gaji');
    $simpan = $obj->save();
    if ($simpan == 1) {
        $status = "Tersmpan";
    } else {
        $status = "Gagal";
    }
    echo json_encode(array("status" => $status));
}

路线

Route::post('/simpanjabatan', 'FormJabatanController@simpanjabatan');

我想用json插入，但出现erorr：

  

此路由不支持GET方法。支持的方法：POST。
