Php Laravel5.1Ajax正在删除会话值

我有一个ajax调用，有时有效，有时无效，完全是随机的，因为它似乎是在同一个视图中的多个位置调用此ajax，对某些人有效，对其他人无效，有时对所有人都有效

function callAjax(id_projeto){
    $.ajax({
          url: "{{ URL::to('/thatPlaceOverThere') }}",
          type: "post",
          data: {'_token'   : '{{ csrf_token() }}',
                 'id_projeto': id_projeto
                 },
          error: function(erro){
              // Error Suff //
          },
          success: function(data){
              // Ok Suff //
          }// success
    });
}

工作的一部分有时是问题1。为什么会在localhost中发生这种情况

现在，第二个也是更令人费解的问题。此ajax调用正在删除我的会话值。代币和闪光都在那里，但我猜拉威尔只是把它放回去了，我放进去的任何值都没有了

如果ajax调用被删除，会话值将保持不变

会话值在如下中间件中设置

$request->session()->put('id_usuario', $id_usuario); 

我的会话文件：

laravel 5.1和PHP7.0.3都会出现这种情况。

能否显示show the controller方法？能否显示show the controller方法？
