用VSCode和Docker调试PHP

我试图用VSCode调试运行在Docker上的PHP应用程序,但没有成功。

在过去,我可以用运行WAMP服务器的VSCode轻松调试PHP应用程序,但自从我开始使用Docker之后,我就无法让调试正常工作。在网上搜索了一些教程,在StackOverflow上查看了一些线程(例如: Docker and XDebug not reading breakpoints VSCode ),但我还是没能让它工作。

Dockerfile文件:

FROM php:7.1.8-apache

]

更新:

docker-compose.yml公司

ports:
  - 18080:80
  - 14430:443
  - 9000:9000 //added new xdebug default port

启动.json

"configurations": [
    {
        "name": "Listen for XDebug",
        "type": "php",
        "request": "launch",
        "pathMappings": {
           "/srv/app/cms": "${workspaceRoot}/my.app/cms",
        },
        "port": 9000,
        "log": true
    }
]

<- launchResponse
Response {
seq: 0,
type: 'response',
request_seq: 2,
command: 'launch',
success: true }

更新#2: 从docker-compose.yml设置中删除了Xdebug端口(9000)。以下是xdebug日志结果:

还有什么建议吗?

更新#3:使用以下设置解决了我的问题:

启动.json

{
    "version": "0.2.0",
    "configurations": [{
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000,
            "log": true,
            "externalConsole": false,
            "pathMappings": {
                "/srv/app/cms": "${workspaceRoot}/cms",
            },
            "ignore": [
                "**/vendor/**/*.php"
            ]
        },
    ]
}
