XDEBUG总是监听新请求，并阻止加载网页，以防我不监听

2022-04-25 00:00:00 php php-7 xdebug php-7.4 xdebug-3

我在我的新工作场所有一个奇怪的设置，它的工作方式如下：如果我运行了PhpStorm，并且&开始侦听PHP调试连接，那么我的本地PHP应用程序工作得很好。一旦我完全关闭PhpStorm(并因此停止侦听PHP调试连接)，我的网页就不会加载(nginx在一分钟后超时)。

这是我的xdebug.ini配置：

xdebug.mode=debug 
xdebug.start_with_request=no 
xdebug.discover_client_host=no
xdebug.client_host=127.0.0.1 
xdebug.log_level=0 
;xdebug.log=/var/log/xdebug.log

以下是php -i | grep -i xdebug的输出：

有趣的是，我甚至试图完全卸载XDEBUG，但仍然存在同样的问题(我不确定我是否做得正确)。

我有什么办法阻止XDEBUG建立连接吗？(只有在我实际需要调试时才启用它)

我使用的是PHP7.4.25，XDEBUG v3.1.1，并在Windows(Ubuntu 20.04)上的WSL下运行它。我还在运行nginx v1.21.4之后的所有内容。

更新1：正如@LazyOne所问的，下面是我的xdebug_info()输出：

解决方案

我是否可以阻止XDEBUG侦听？

不会，因为监听的不是XDEBUG。XDEBUG与PhpStorm建立连接，PhpStorm可以侦听传入的调试连接。

可能由于某些原因，XDEBUG仍然尝试建立到IDE的连接，即使它没有侦听。连接时，XDEBUG端通常有200毫秒的超时，但我看到一些网络设置阻止了这一点。

为了查明XDEBUG是否仍在执行某些操作，请创建一个日志文件，方法是将xdebug.ini更改为包括以下内容，然后重新启动Apache：

xdebug.log_level=10 
xdebug.log=/var/log/xdebug.log

日志文件将详细显示Xdebug是否仍在尝试连接(因为您将xdebug.log_level设置为10)。
