更新到 WSL2 后無法從 PhpStorm 連接到 Xdebug

Question

環境

• 操作系統：Windows 10 專業版 1909
• WSL：Ubuntu (18.04. 5)
• PHP：7.3
• PhpStorm：2020.2

聽說WSL2可以在1909上運行，於是我把我的Ubuntu從WSL1升級到了2，設置好后嘗試用PhpStorm調試時，“連接未建立”。 被顯示。

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

被顯示。

我嘗試更改各種 Xdebug 設置，但無法連接到其中任何一個。

從WSL2開始，IP地址不一樣了，但是聽說現在可以用localhost了，所以改成localhost了，還是不行。

目前是不是不能用WSL2了？ 或者有什么辦法嗎？ 先感謝您。

• 您需要獲取 Windows 主機的 IP 地址。 您可以通過檢查網絡設置或在 DOS 提示符下（不在 WSL2 內）簡單地通過ipconfig來完成此操作。

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，它是 IPv4 地址的值，即192.168.2.115 。

• 在 PhpStorm 中，轉到設置 > 語言和框架 > PHP > 調試

• 打開高級設置並啟用“傳遞所需的配置選項...”

• 選擇您的 PHP > CLI 解釋器

• 單擊“配置選項”上的文件夾圖標

• 點擊“加號”並添加一個新條目

• 把xdebug.remote_host作為鍵

• 將您的本地 IP 地址 ( 192.168.2.115 ) 作為值

這將使 WSL2 中的 Xdebug 允許連接回您的 Windows 主機。
