注意:未定义的索引:HTTP_REFERER

$ http_referer = $ _SERVER ['HTTP_REFERER']

我在教程中使用了它.它看起来没问题

代码也是从包含文件调用它

我应该改变什么？

我添加了print_r($ _ SERVER); 现在页面给了我这个

 Array ([UNIQUE_ID] => UoSxWa56310AAAwUckIAAAAA

我有以下情况:

  try {

        DB::beginTransaction();

        $task = new Task();
        $task->setTracker("");
        //thrown \Symfony\Component\Debug\Exception\FatalThrowableError


            DB::commit();

        }catch (\Exception $e){
            DB::rollBack();
            Log::error($e);
            //throw $e;
        }

我没有进入捕捞区.
知道为什么吗？

更新

这是抛出的错误:

[Symfony\Component\Debug\Exception\FatalThrowableError]
Type error: Argument 1 passed to App\Models\Task::setTracker() must be an instance of Carbon\Carbon, integer given, called in /var/www/app/Services/ShareLogic.php on line 60

并且不会被抓住

谢谢

今天我在写一些java脚本的基本内容时遇到了问题.虽然我能够解决问题,但找不到为什么这不起作用的原因.这是我的代码

$('document').ready(function() {
     $(this).click(function() {
         var node1 = $(this);
         a = node1.text();
         console.log(a);
     });
 });

在控制台中我看到空字符串.但是,如果我更改$(this).click(function{...})为$('.some_class_name').click(function{.....});我的代码工作正常,并显示我单击按钮的文本值.我想知道上面的代码有什么问题.
