Laravel - 阅读所有可用语言，但所有翻译都是德语

Question

我在laravel 有一个服务提供商，它从locale 读取所有可用的语言并将它们保存在缓存文件中。一切正常，但所有翻译都是德语。我希望以de 和en 的语言获得它们。 这是来自ServiceProvider的代码：

$minutes = 24 * 60;
Cache::remember('translations', $minutes, function () {
    $directories = array('de', 'en');
    $collection = new \stdClass;
    foreach ($directories as $directory) {
        $path = resource_path('lang/' . $directory);
        $allTranslations = collect(File::allFiles($path))->flatMap(function ($file, $directory) {
            return [
                ($translation = $file->getBasename('.php')) => trans($translation, array(), null, $directory),
            ];
        });
        $allModuleTranslations = collect(File::allFiles($path . '/modul'))->flatMap(function ($file, $directory) {
            return [
                ($translation = $file->getBasename('.php')) => trans('modul/' . $translation, array(), null, $directory),
            ];
        });
        $collection->$directory = $allTranslations->merge($allModuleTranslations);
    }
    return json_encode($collection);
});

谁能看到，为什么它会返回所有德语单词？

结果如下：

{
   de:
      auth:
         failed: "Diese Zugangsdaten wurden nicht in unserer Datenbank gefunden."
         throttle: "Zu viele Login Versuche. Versuchen Sie es bitte in :seconds Sekunden."
   en:
      auth:
         failed: "Diese Zugangsdaten wurden nicht in unserer Datenbank gefunden."
         throttle: "Zu viele Login Versuche. Versuchen Sie es bitte in :seconds Sekunden."
}

Answer 1

1. 您必须使用use 从父作用域导入$directory 变量，它不会通过flatMap() 回调传递

2. trans 只有 3 个参数，但您传递了 4 个参数

    mixed trans(string $key, array $replace = [], string|null $locale = null)

这应该可行：

$minutes = 24 * 60;
Cache::remember('translations', $minutes, function () {
    $directories = array('de', 'en');
    $collection = new \stdClass;
    foreach ($directories as $directory) {
        $path = resource_path('lang/' . $directory);
        $allTranslations = collect(File::allFiles($path))
            ->flatMap(function ($file) use ($directory) {
                return [
                    ($translation = $file->getBasename('.php')) => trans($translation, array(), $directory),
                ];
            });
        $allModuleTranslations = collect(File::allFiles($path . '/modul'))
            ->flatMap(function ($file) use ($directory) {
                return [
                    ($translation = $file->getBasename('.php')) => trans('modul/' . $translation, array(), $directory),
                ];
            });
        $collection->$directory = $allTranslations->merge($allModuleTranslations);
    }
    return json_encode($collection);
});
