Xdebug:[步骤调试]无法连接到调试客户端

Question

我想尝试一下XDebug3.0.0RC1，以了解它发生了什么变化以及带来的新特性。我还使用了最新的PhpStorm 2020.3 EAP，它支持XDebug3，不需要主要配置。下面是调试器的PhpStorm配置：

下面是我为XDebug3尝试的配置：

zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20170718/xdebug.so
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.client_host=host.docker.internal # here I tried several combinations like: "localhost", "127.0.0.1", "172.17.0.1"
xdebug.client_port=9001 # here I tried several ports 9003 included with no success

我还尝试完全不添加client_host/client_port设置，但仍然失败。

Script php bin/console doctrine:cache:clear-metadata returned with error code 255
!!  [17-Nov-2020 15:24:40 UTC] Xdebug: [Step Debug] Could not connect to debugging client. Tried: host.docker.internal:9001 (through xdebug.client_host/xdebug.client_port) :-(

null

zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20170718/xdebug.so
xdebug.remote_autostart=0
xdebug.remote_enable=1
xdebug.remote_host=host.docker.internal
xdebug.remote_port=9000

注意：我已经在这里应用了Xdebug开发人员提供的解决方案。

PHP 7.4
Docker
PHPStorm 2020.1
Xdebug 3.1.0

使用Dockerfile在docker容器中安装Xdebug

RUN pecl install xdebug-3.0.1 && docker-php-ext-enable xdebug

用以下方法配置php.ini：

[xdebug]
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.discover_client_host = 1

[xdebug]
xdebug.mode = debug
xdebug.discover_client_host = 1
