在 Laravel 6、Module 中，自定义验证规则的 message 中翻译不可用的排查(延迟提供者的使用导致)
1、参考：https://www.shuijingwanwq.com/2022/04/26/6341/
2、在一段时间后，突然发现自定义验证规则的 message 中翻译不可用。验证失败时响应的 message 未被翻译。如图1

3、参考：https://www.shuijingwanwq.com/2022/06/29/6707/ ，当删除 implements DeferrableProvider 后，再清空目录：/bootstrap/cache 后，翻译正常工作。如图2

4、在模块的服务提供者中的现有实现如下
1 2 3 4 5 6 7 8 9 10 11 12 | class GraphQlResolverServiceProvider extends ServiceProvider implements DeferrableProvider{ /** * @return void */ public function register() { $this->registerTranslations(); // ... }} |
5、参考：/vendor/laravel/framework/src/Illuminate/Translation/TranslationServiceProvider.php ，代码调整如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 | class GraphQlResolverServiceProvider extends ServiceProvider implements DeferrableProvider{ /** * @return void */ public function register() { $this->registerLoader(); $this->app->singleton('translator', function ($app) { $loader = $app['translation.loader']; // When registering the translator component, we'll need to set the default // locale as well as the fallback locale. So, we'll grab the application // configuration so we can easily get both of these values from there. $locale = $app['config']['app.locale']; $trans = new Translator($loader, $locale); $trans->setFallback($app['config']['app.fallback_locale']); return $trans; }); $this->registerTranslations(); // ... } /** * Register the translation line loader. * * @return void */ protected function registerLoader() { $this->app->singleton('translation.loader', function ($app) { return new FileLoader($app['files'], $app['path.lang']); }); } /** * Register translations. * * @return void */ public function registerTranslations() { $langPath = resource_path('lang/modules/' . $this->moduleNameLower); if (is_dir($langPath)) { $this->loadTranslationsFrom($langPath, $this->moduleNameLower); } else { $this->loadTranslationsFrom(__DIR__ . '/../Resources/lang', $this->moduleNameLower); } } /** * 获取由提供者提供的服务。 * * @return array */ public function provides() { return ['translator', 'translation.loader']; }} |
6、翻译正常运行。但是这样的话，感觉代码冗余得厉害。决定再次调整一下，将延迟加载的服务单独剥离出一个类。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | class OnlineStoreThemeGraphQLServiceProvider extends ServiceProvider{ private $moduleNameLower = 'online_store_theme_graphql'; /** * @return void */ public function register() { $this->app->register(ResolverServiceProvider::class); $this->registerTranslations(); } /** * Register translations. * * @return void */ public function registerTranslations() { $langPath = resource_path('lang/modules/' . $this->moduleNameLower); if (is_dir($langPath)) { $this->loadTranslationsFrom($langPath, $this->moduleNameLower); } else { $this->loadTranslationsFrom(__DIR__ . '/../Resources/lang', $this->moduleNameLower); } } /** * 获取由提供者提供的服务。 * * @return array */ public function provides() { return []; }} |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | class ResolverServiceProvider extends ServiceProvider implements DeferrableProvider{ /** * Register the service provider. * * @return void */ public function register() { $this->app->singleton(SettingPersistenceInterface::class, function($app){ return new DbSettingPersister(); }); $this->app->singleton(ThemeAssetRepositoryInterface::class, function($app){ return new ThemeAssetRepository(); }); } /** * Get the services provided by the provider. * * @return array */ public function provides() { return [SettingPersistenceInterface::class, ThemeAssetRepositoryInterface::class]; }} |
7、翻译正常工作。如图3
