我尝试在我的Docker容器中设置Xdebug步骤调试器，以便能够连接到我的Docker容器。
这是我的项目中.vscode目录下launch.json的配置片段：

{
    "name": "Xdebug",
    "type": "php",
    "request": "launch",
    "hostname": "127.0.0.1",
    "port": 9000,
    "pathMappings": {
        "/var/www/html/": "${workspaceFolder}/code/",
    },
},

这是我的docker-compose.yml的代码片段：

services: 
  webserver:
    container_name: webserver_orderlinev3
    build: webserver
    ports: 
      - 8080:80
      - 9000:9000
    volumes: 
      - ./code:/var/www/html
      - ./webserver/php-ini-overrides.ini:/usr/local/etc/php/conf.d/php-ini-overrides.ini
      - ./webserver/phpsessions:/var/www/phpsessionfiles
      - ./xdebuglog:/tmp/xdbglog

    extra_hosts:
      - host.docker.internal:host-gateway
    environment:
      - XDEBUG_MODE=debug,develop,coverage,profile,trace

还有那些我的php.ini覆盖了

[session]
session.save_handler=files
session.save_path="/var/www/phpsessionfiles"

[xdebug]
xdebug.client_port=9000
xdebug.mode=off

xdebug.discover_client_host=on
xdebug.client_host = host.docker.internal

xdebug.remote_connect_back=0
xdebug.remote_enable=on
xdebug.remote_handler=dbgp

xdebug.start_with_request = yes
xdebug.log=/tmp/xdbglog/xdebug_remote.log

因为这是xdebug.log的日志输出

我没有得到任何线索，为什么它实际上是不工作的。
主机端口到访客端口的重定向似乎是工作，因为我可以通过localhost:8080连接到Web服务器，我现在看了几个YouTube教程这个主题，但我不知道我做错了什么。
Xdebug似乎连接到docker.host.internal，但网关似乎阻止了这一点-尽管我关闭了我的防火墙，甚至为了测试（再次打开它）。
有在Docker和Xdebug方面经验的人可以帮助我吗？我将非常感激。
另外，我没有使用任何VPN连接-它被禁用正是因为这个原因。
