我有一个服务提供商：
<?php namespace App'Providers;
use Carbon'Carbon;
use Illuminate'Support'Collection;
use Illuminate'Support'ServiceProvider;
use Illuminate'Contracts'Cache'Store;
use File;
use App'Models'Translation;
class ModuleTranslationsServiceProvider extends ServiceProvider {
protected $cache;
public function __construct (Store $cache) {
$this->cache = $cache;
}
/**
* Load the config from the database.
*
* @return void
*/
public function register()
{
$translations = $this->cache->remember('translations', function() {
//Load and return translations.
});
$this->app->singleton('translations', function($app) use ($translations) {
return $translations;
});
}
}
然而，当应用程序运行时（工匠或浏览器），我得到以下错误：
ErrorException]
Argument 1 passed to App'Providers'ModuleTranslationsServiceProvider::__construct() must be an instance of Illuminate'Contracts'Cache'Store, instance of Illuminate'Foundation'Application given, called in /home/user/projects/AppPlatform/vendor/laravel/framework/
src/Illuminate/Foundation/ProviderRepository.php on line 150 and defined
通常，Laravel通过构造函数自动注入合同。这是对服务提供商的限制吗？还是我做错了？
编辑：
我更改了代码以反映Iamzozo:的建议
public function boot(Store $cache) {
$this->cache = $cache;
}
但这只回来了：
[Symfony'Component'Debug'Exception'FatalErrorException]
Call to a member function remember() on null
所以我尝试从应用程序实例化：
$cache = $this->app['Illuminate'Cache'CacheManager'];
但这只回来了：
[ReflectionException]
Class cache does not exist
尝试实例化合同：
$cache = $this->app['Illuminate'Contracts'Cache'Store'];
给我一个：
[Illuminate'Container'BindingResolutionException]
Target [Illuminate'Contracts'Cache'Store] is not instantiable.
我所知道的最后一件事：使用门面：
use Cache;
//...
$translations = Cache::remember( [...]
但这反过来又回来了：
[Symfony'Component'Debug'Exception'FatalErrorException]
Call to undefined method Illuminate'Support'Facades'Cache::remember()
所以我检查了我的提供商阵列：
'providers' => [
/*
* ...
*/
'Illuminate'Cache'CacheServiceProvider',
/*
* ...
*/
'App'Providers'ModuleTranslationsServiceProvider',
],
所以缓存是在我的服务提供商之前加载的。
在这一点上我没有新的想法。
php版本是通过Apache在php-FPM上运行的5.6.4。Laravel版本为5.0。
也许我不清楚我的答案，所以我更新了整个解决方案，这个解决方案适用于Laravel 5.1:
<?php namespace App'Providers;
use Carbon'Carbon;
use Illuminate'Support'Collection;
use Illuminate'Support'ServiceProvider;
use Illuminate'Cache'CacheManager as Cache;
use File;
use App'Models'Translation;
class ModuleTranslationsServiceProvider extends ServiceProvider {
/**
* Load the config from the database.
*
* @return void
*/
public function register()
{
// Update for redis:
$this->app->register('Illuminate'Redis'RedisServiceProvider::class);
$cache = new Cache($this->app);
$translations = $cache->remember('translations', function() {
//Load and return translations.
});
$this->app->singleton('translations', function($app) use ($translations) {
return $translations;
});
}
}
我没有意识到，你尝试使用的Cache'Store是一个接口。
