2、查看 \vendor\laravel\telescope\src\Watchers\EventWatcher.php:91
if (is_string($listener)) { return Str::contains($listener, '@') ? $listener : $listener.'@handle'; } elseif (is_array($listener)) { return get_class($listener[0]).'@'.$listener[1]; }
3、查看 EventServiceProvider
/** * The event listener mappings for the application. * * @var array */ protected $listen = [ ThemeUpdated::class => [ ThemeUpdatedWebhookListener::class ], ];
4、这看起来像一个 Bug,我看到有一个新的提交正好解决了这个问题。提交:https://github.com/laravel/telescope/commit/a69fc6f4f5fd5b0ac5a242981e162774cbb69e17 。support new listeners syntax。如图2
5、我暂未升级,而是参考提交的变更,编辑 \vendor\laravel\telescope\src\Watchers\EventWatcher.php
if (is_string($listener)) { return Str::contains($listener, '@') ? $listener : $listener.'@handle'; } elseif (is_array($listener) && is_string($listener[0])) { return $listener[0].'@'.$listener[1]; } elseif (is_array($listener) && is_object($listener[0])) { return get_class($listener[0]).'@'.$listener[1]; }
6、再次运行程序,不再报错。后续决定升级 Laravel Telescope 至包含这个提交的版本。
