php - Laravel 扩展供应商类

Question

我尝试扩展一个 Illuminate 类翻译器

我创建了一个类并扩展到翻译器然后我将这一行添加到我的 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(bind)必须通过接口(interface)..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);
    });        
}

出现这个错误

Illuminate\Contracts\Container\BindingResolutionException with message 'Target [Illuminate\Translation\LoaderInterface] is not instantiable while building [App\Repositories\Translation\TranslationTranslator].'

您可以使用闭包来解析类

$this->app->bind(\Illuminate\Translation\Translator::class, function(){

    return new \App\Repositories\Translation\TranslationTranslator;
});

其次翻译器在使用翻译器别名时与laravel绑定(bind)。

您也可以覆盖它。

$this->app->bind('translator', function(){
        return new \App\Repositories\Translation\TranslationTranslator; 
    })
