使用带有 laravel 的 mailcatcher 时遇到错误（“laravel/framework”：“^8.54”，）

"message": "Connection could not be established with host localhost :stream_socket_client(): unable to connect to localhost:8003 (Cannot assign requested address)",
  "exception": "Swift_TransportException",
  "file": "/var/www/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php",
  "line": 261,

所以，我像往常一样发送电子邮件，我检查了使用的默认邮件smpt

配置/邮件.php

'mailers' => [
    'smtp' => [
        'transport' => 'smtp',
        'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
        'port' => env('MAIL_PORT', 587),
        'encryption' => env('MAIL_ENCRYPTION', 'tls'),
        'username' => env('MAIL_USERNAME'),
        'password' => env('MAIL_PASSWORD'),
        'timeout' => null,
        'auth_mode' => null,
    ],

在代码中

use Illuminate\Support\Facades\Mail;
//

Mail::send((new ContactUsEmail($contactUs)));

我的 .env

MAIL_MAILER=smtp
MAIL_HOST=localhost
MAIL_PORT=8003
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_ADDRESS=from_admin@admin.com
MAIL_TO_ADDRESS=to_admin@admin.com
MAIL_FROM_NAME="${APP_NAME}"
MAIL_TO_NAME=admin

当我在 \Swift_Transport_StreamBuffer 中调试它时

params = {array} [8]
 protocol = ""
 host = "localhost"
 port = {int} 8003
 timeout = {int} 30
 blocking = {int} 1
 tls = false
 type = {int} 1
 stream_context_options = {array} [0]

看起来端口正确

当我打开 mailcatcher 时可用http://localhost:8100/

我做错了什么？

更新

从 php 容器执行 ping

/var/www# ping mailcatcher
PING mailcatcher (172.23.0.2) 56(84) bytes of data.
64 bytes from myapp-mailcatcher.docker_mailcatcher-larabostad-networks (172.23.0.2): icmp_seq=1 ttl=64 time=0.237 ms
64 bytes from myapp-mailcatcher.docker_mailcatcher-larabostad-networks (172.23.0.2): icmp_seq=2 ttl=64 time=0.138 ms

新错误

  "exception": "Swift_TransportException",

compose 中的所有 docker 服务都在一个网络中工作（默认情况下）。如果您想从一项服务连接到另一项服务，请使用他们的名称。而且，因为您连接到专用网络 - 使用标准端口

MAIL_HOST=mailcatcher
MAIL_PORT=1025
