VSCode无法连接到Xdebug

Question

我试图在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目录中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

以及那些我的php.ini覆盖的地方

[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

我不知道为什么它实际上不起作用。

主机端口到来宾端口重定向似乎正在工作，因为我可以通过localhost:8080连接到Web服务器我现在在YouTube上看了几个关于这个话题的教程，但我不知道自己做错了什么。

Xdebug似乎连接到docker.host.internal，但网关似乎阻止了这一点——尽管我甚至为了测试而关闭了防火墙(再次打开(。

有docker和Xdebug经验的人可以帮助我吗？我真的很感激。

附言：我没有使用任何VPN连接——正是因为这个原因，它被禁用了。

谢谢，它终于开始运行了如果没有@LazyOne，我会在这里再呆一段时间，特别感谢他<3
