我试图让Xdebug在我的本地机器上工作，但遇到了以下问题：Xdebug没有连接到VSCode。
我的安装程序是在Windows 10上的WSL和Visual Studio代码上使用Docker容器。
当我尝试Xdebug时，我得到以下错误：

[Step Debug] Creating socket for '192.168.16.1:9004', poll success, but error: Operation now in progress (29).  🖹
⚠️  [Step Debug] Could not connect to client host discovered through HTTP headers, connecting to configured address/port: localhost:9004. :-|   🖹
⚠️  [Step Debug] Creating socket for 'localhost:9004', poll success, but error: Operation now in progress (29). 🖹
⚠️  [Step Debug] Creating socket for 'localhost:9004', connect: Cannot assign requested address.    🖹
🛑  [Step Debug] Could not connect to debugging client. Tried: 192.168.16.1:9004 (from REMOTE_ADDR HTTP header), localhost:9004 (fallback through xdebug.client_host/xdebug.client_port) :-(`

这些是我的设置：
launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9004,
            "stopOnEntry": true,
            "log": true,
            "hostname" : "localhost",
            "pathMappings": 
            {
                "/var/www/html/": "${workspaceRoot}/docker/wordpress/public/"             
            }
        },
        {
            "name": "Launch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",
            "port": 9004
        }
    ]  
}

php.ini

[xdebug]
#zend_extension = ./lib/php/20180731/xdebug.so
xdebug.start_with_request = trigger 
xdebug.mode = debug
xdebug.discover_client_host = 1
xdebug.log = /tmp/xdebug_remote.log
xdebug.client_port = 9004

我已经测试了端口9003，它不工作。当我检查是否有可用的telnet连接时，它会连接。我还在防火墙上启用了端口。
编辑：我已经找到了一个配置，为我工作的基础上提供的链接从@LazyOne。
我更新了以下配置并使用了浏览器扩展。
