Laravel 扩展供应商类

Question

我尝试扩展 Illuminate Class Translator

我创建了一个类并扩展到翻译器，然后将此行添加到我的 RepositoryServiceProvider

$this->app->bind(\Illuminate\Translation\Translator::class, \App\Repositories\Translation\TranslationTranslator::class);

但它不起作用

我究竟做错了什么？

类如下

<?php

namespace App\Repositories\Translation;

use Countable;
use Illuminate\Support\Arr;
use Illuminate\Support\Str;
use Illuminate\Support\Collection;
use Illuminate\Support\Traits\Macroable;
use Illuminate\Support\NamespacedItemResolver;
use Symfony\Component\Translation\MessageSelector;
use Symfony\Component\Translation\TranslatorInterface;


class TranslationTranslator extends \Illuminate\Translation\Translator
{
    /**
     * Parse a key into namespace, group, and item.
     *
     * @param  string  $key
     * @return array
     */
    public function parseKey($key)
    {
        \Log::info('got in');
        die;
        $segments = parent::parseKey($key);

        if (is_null($segments[0])) {
            $segments[0] = @explode('.', $segments[2])[0];
        }
        if ($segments[1] == 'translatable') {
            $segments[1] = @explode('.', $segments[2])[0] . '_' . @explode('.', $segments[2])[1];
        }
        return $segments;
    }
}

更新

显然 Translator 类有一个构造函数

 public function __construct(LoaderInterface $loader, $locale)
    {
        $this->loader = $loader;
        $this->locale = $locale;
    }

所以我的绑定必须通过接口..无法实例化

 public function boot()
{
    $app = $this->app;
    $this->app->bind(\Illuminate\Translation\Translator::class, function() use ($app){
        return $app->make(\App\Repositories\Translation\TranslationTranslator::class);
    });        
}

并收到此错误

Illuminate\Contracts\Container\BindingResolutionException 消息“Target [Illuminate\Translation\LoaderInterface] 在构建 [App\Repositories\Translation\TranslationTranslator] 时不可实例化。”

尝试将其更改为这样：

$this->app->instance(\Illuminate\Translation\Translator::class, \App\Repositories\Translation\TranslationTranslator::class);

然后应该更改接口的实例。

更新

如果您只是想添加一个新方法，则 Translator 类是 Macroable。所以你可以执行以下操作

Translator::macro('parseKey', function ($key) {
    \Log::info('got in');
    die;
    $segments = parent::parseKey($key);

    if (is_null($segments[0])) {
        $segments[0] = @explode('.', $segments[2])[0];
    }
    if ($segments[1] == 'translatable') {
        $segments[1] = @explode('.', $segments[2])[0] . '_' . @explode('.', $segments[2])[1];
    }
    return $segments;
});

然后您就可以像平常一样调用您的方法。例如：

app(Translator::class)->parseKey($key);
