使用 VSCode 和 Docker 调试 PHP

Debug PHP with VSCode and Docker

我正在尝试使用 VSCode 在 Docker 上调试 PHP 应用程序 运行,但没有成功。

过去我能够使用 VSCode 运行 WAMP 服务器轻松调试我的 PHP 应用程序,但自从我开始使用 Docker 我无法让调试工作。在线搜索了几个教程,在 Whosebug 上检查了一些主题(例如:),但我仍然无法正常工作。

Docker文件:

FROM php:7.1.8-apache

COPY /cms /srv/app/cms
COPY .docker/cms/vhosts/vhost.conf /etc/apache2/sites-available/cms.conf
COPY .docker/cms/vhosts/vhost-ssl.conf /etc/apache2/sites-available/cms-ssl.conf
COPY .docker/cms/vhosts/certificate.conf /etc/ssl/certs/certificate.conf
COPY .docker/cms/xdebug.ini /usr/local/etc/php/conf.d/xdebug.ini

xdebug.remote_connect_back=0
xdebug.remote_host='host.docker.internal'
xdebug.idekey='VSCODE'
xdebug.remote_autostart=1

docker-compose.yml

version: '3.7'
services:
cms:
  build:
    context: .
    dockerfile: .docker/cms/Dockerfile
  image: php:7.1.8-apache
  ports:

    VIRTUAL_HOST: my.app.localhost
    PHP_EXTENSION_XDEBUG: 1

VSCode: launch.json

"configurations": [
    {
        "name": "Listen for XDebug",
        "type": "php",
        "request": "launch",
        "pathMappings": {
           "/srv/app/cms": "${workspaceRoot}/my.app/cms",
        },
        "port": 9000
    }, {
        "name": "Launch currently open script",
        "type": "php",
        "request": "launch",
        "program": "${file}",
        "cwd": "${fileDirname}",
        "port": 9000
    }
]

当我调试应用程序时,没有触发断点。我做错了什么?

更新: 根据一些建议,我更新了我的 docker-compose.yml 和我的 launch.json 文件,但没有任何改变。

docker-compose.yml

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

launch.json

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

VSCode调试控制台:

<- 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)。这是 xdebug 日志结果:

Log opened at 2018-09-30 22:21:09 I: Connecting to configured address/port: host.docker.internal:9000. E: Time-out connecting to client (Waited: 200 ms). :-( Log closed at 2018-09-30 22:21:09

还有什么建议吗?

您在 docker-compose.yml

中缺少端口 :9000(或 :9001

需要可连接,以便 IDE 从外部连接。

对于 VSCode,可能需要 PHP Debug 扩展才能与 xdebug 交互。

默认 launch.json 仅使用 port: 9000 一次 - 并且具有 log: true.

{
  "configurations": [{
      "name": "Listen for XDebug",
      "type": "php",
      "request": "launch",
      "port": 9000,
      "log": true
    }, {
      "name": "Launch",
      "request": "launch",
      "type": "php",
      "program": "${file}",
      "cwd": "${workspaceRoot}",
      "externalConsole": false
    }
  ]
}

通过以下设置设法解决了我的问题:

launch.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"
            ]
        },
    ]
}

xdebug.ini

zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20160303/xdebug.so
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.remote_connect_back=0
xdebug.remote_host=host.docker.internal
xdebug.idekey=VSCODE
xdebug.remote_autostart=1
xdebug.remote_log=/usr/local/etc/php/xdebug.log

从 xdebug 版本 3 开始,配置名称发生了重大变化。

我当前的工作 dockerfile:

RUN apt-get update; \
        apt-get -y --no-install-recommends install \
            php7.4-dev \
            php-pear \
            libcurl3-openssl-dev \
            libmcrypt-dev \
            libxml2-dev \
            libpng-dev \
        ; \
        pecl install xdebug; \
        { \
            echo "[xdebug]"; \
            echo "zend_extension=$(find /usr/lib/php/ -name xdebug.so)"; \
            echo "xdebug.mode=debug"; \
            echo "xdebug.start_with_request=yes"; \
            echo "xdebug.client_host=host.docker.internal"; \
            echo "xdebug.client_port=9001"; \
        } >> /etc/php/7.4/mods-available/xdebug.ini; \
        phpenmod -v 7.4 xdebug; \

VSC 调试配置:

    "configurations": [
        {
            "name": "XDebug (Docker)",
            "type": "php",
            "request": "launch",
            "port": 9001,
            "pathMappings": {
                "/var/www/app": "${workspaceRoot}",
            }
        }
    ]

###> XDEBUG 3 ###
# Use your client IP here
# Linux: run "ip a | grep docker0"

xdebug.ini

xdebug.mode=debug,coverage
xdebug.start_with_request=yes
xdebug.client_host=${XDEBUG_CLIENT_HOST}

示例配置vscode修改pathMappings

launch.json:

{

    "version": "0.2.0",
    "configurations": [{
        "name": "Listen for XDebug",
        "type": "php",
        "request": "launch",

        "log": true,
        "externalConsole": false,
        "pathMappings": {
            "/appdata/www": "${workspaceRoot}/api",
        },
        "ignore": [
            "**/vendor/**/*.php"
        ]
    },
]
}

对于以下堆栈中的每个人 运行:

  • Ubuntu
  • X调试3
  • Laravel启航

docker/8.0/php.ini

[xdebug]

launch.json

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

好吧,我已经尝试了以上所有答案并花了几个小时但没有成功,因为在以上所有答案中,一些概念对像我这样的新 x-debug 用户来说不清楚。我希望我在开始设置 x-调试器之前知道以下概念,运行 在 docker 容器或远程服务器上,使用我的 VS Code 的 PHP 调试。我相信这将有助于寻找此类问题的解决方案。

X-调试设置

我不确定我的机器应该被视为客户端主机还是服务器主机,虽然这很明显,但当您在配置上花费数小时后,简单的事情开始变得棘手。

xdebug.client_host

根据 X-debug 文档:

This address should be the address of the machine where your IDE or debugging client is listening for incoming debugging connections.

我想,上面这段文字就不用解释了吧。因此,在我们的 x-debug 配置中按如下方式设置它,即 xdebug.ini:

xdebug.client_host=host.docker.internal

xdebug.remote_host

这对我来说有点棘手。实际上 x-debug 没有这样的配置,但我一直在考虑它。 :-)

PHP-调试设置

主机名

我一直在使用不同的配置,除了这个(因为在这个线程中没有人提到这个):-)但没有成功。然后我重新探索了 PHP Debug 的文档,知道在我的情况下它必须设置为 localhost,然后试了一下,然后砰!成功了!

"hostname": "localhost"

端口

应该设置为与xdebug.client_port相同,默认值为9300。在上面的答案中重复提到。

路径映射

这是尝试使用 VS Code PHP 调试设置 docker 服务器时的另一个非常重要的配置。它是一个对象,必须将您的本地目录结构映射到 server/container 目录,即 /home/user/proj/html:${workspaceRoot}。我无法进一步解释它,它确实对我有用,我已经在这里提到了它。如果有人解释一下,我将不胜感激。

这是我的最终设置:

希望这会有所帮助并节省您的时间:-)
