对于 xdebug ang php，此消息的解决方法是什么？

Xdebug: [Step Debug] Could not connect to debugging client. Tried: localhost:9003 (fallback through xdebug.client_host/xdebug.client_port) :-(

composer update当我在WSL2安装时运行时显示此消息UBUNTU 20.01。

我当前的 php 版本是php8和xdebug3

更新：

这是 x-debug 部分

首先是什么导致该消息：

你有xdebug.start_with_request = yes（这与xdebug.remote_autostart = yesXdebug v2 相同）。此选项告诉 Xdebug 尝试调试每个请求/脚本，而不管“调试我”标志。

如果 Xdebug 无法连接到调试客户端（值来自xdebug.client_host& xdebug.client_port.. 或自动检测主机，如果xdebug.discover_client_host启用），那么它会通知您。

如何防止它出现在我的屏幕上/输出中：

Xdebug 使用标准 PHP 例程来编写此类警告（例如标准 PHPerror_log()函数）。通常这样的消息会被写入标准PHP 的错误日志中。看起来你根本没有在你的php.ini（空值）中配置它，因此 PHP 将它发送到你的标准输出（所以你仍然有机会看到它，因为它可能很重要）。

解决方案是将PHP 的error_logini 设置指向某个有效位置，以便您可以在需要时读取它（路径取决于您的操作系统和发行版，例如error_log = /var/log/php_error.log会很常见）。如果你根本不需要这样的日志（有其他日志系统）——使用/dev/null或类似的东西。

您也可以尝试xdebug.log_level = 0，但这应该会阻止 Xdebug 记录任何内容，即使您指定xdebug.log.

我正在使用： xdebug.start_with_request=trigger 在需要时触发 xdebug（使用浏览器 xdebug 扩展进行 Web 服务器调试）。

或者如果我需要调试 php 脚本（使用 cli），我使用 phpstorm 配置如下：

使用这种方法，我不会收到此错误，并且可以像往常一样使用 xdebug 日志。

从有关此类错误的 Xdebug文档中：

当 Xdebug 尝试连接到调试客户端以启动调试会话时发生。

调试器无法与客户端建立连接。错误消息指出尝试了哪些主机和端口组合，以及通过哪些配置选项得出该结论。

一个例子：

无法连接到调试客户端。尝试过：（::1:9003来自REMOTE_ADDRHTTP 标头），localhost:9003（通过xdebug.client_host/回退xdebug.client_port）

此消息表明 Xdebug 首先尝试使用::1:9003REMOTE_ADDR 标头中的（IPv6 的 localhost），然后它回退到localhost:9003使用xdebug.client_host和xdebug.client_port 配置的状态。

建议的解决方案：

  • 检查您的调试客户端是否正在侦听指定的地址和端口。在 Linux 和 OSX 上，您可以使用netstat -a -n | grep LISTEN来检查。
  • 更改xdebug.client_host和/或xdebug.client_port调试客户端正在侦听的正确地址/主机名和端口。

不使用时禁用 xdebug 浏览器扩展。

我使用 VSCode 调试器。当在 IDE 中关闭调试时，我在每次访问页面时都会在日志中看到错误，因为我的 chrome 浏览器扩展仍在尝试调用 xdebug。

尽管为 xdebug 设置了良好的 php.ini 设置，但仍会发生这种情况：

xdebug.mode=debug

或者

xdebug.start_with_request=trigger

两者都记录在这里：Xdebug：文档
