更新到 WSL2 后无法从 PhpStorm 连接到 Xdebug

Question

环境

OS: Windows 10 专业版 1909
WSL：Ubuntu (18.04.5)
PHP: 7.3
PhpStorm: 2020.2

我听说 WSL2 可以与 1909 一起使用，所以我将 Ubuntu 从 WSL1 升级到 2。当我在设置后尝试使用 PhpStorm 进行调试时，“未建立连接”。已显示。

然后我看了看日志，

[2640] Log opened at 2020 xx-xx: xx: xx
[2640] I: Connecting to configured address/port: localhost: 9001.
[2640] W: Creating socket for 'localhost: 9001', poll success, but error: Operation now in progress (29).
[2640] E: Could not connect to client.: - (
[2640] Log closed at 2020 xx-xx: xx: xx

已显示。

我尝试更改各种 Xdebug 设置，但无法连接到任何设置。

从WSL2开始，IP地址就不同了，不过听说现在可以用localhost了，所以改成localhost，还是不行。

目前无法使用WSL2吗？或者有什么办法吗？提前谢谢你。

您需要获取 Windows 主机的 IP 地址。您可以通过检查您的网络设置或在 DOS 提示符下（不是在 WSL2 中）简单地通过 ipconfig 来做到这一点。

Ethernet adapter Ethernet:

Connection-specific DNS Suffix  . : Speedport_XXX
   IPv6 Address. . . . . . . . . . . : XXX
   Temporary IPv6 Address. . . . . . : XXX
   Temporary IPv6 Address. . . . . . : XXX
   Link-local IPv6 Address . . . . . : XXX
   IPv4 Address. . . . . . . . . . . : 192.168.2.115
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : fe80::1%8
                                       192.168.2.1

在我的示例中，IPv4 地址的值为 192.168.2.115。

在 PhpStorm 中转到设置 > 语言和框架 > PHP > 调试
打开高级设置并启用“传递所需的配置选项...”
Select 你的 PHP > CLI 解释器
单击“配置选项”上的文件夹图标
点击“加号”并添加一个新条目
作为键xdebug.remote_host
将您的本地 IP 地址 (192.168.2.115) 作为值

这将允许 WSL2 内部的 Xdebug 连接回您的 windows 主机。
