Laravel ServiceProvider Class 未在包中找到

Question

我已经在我的 Windows 7 64 位 Uwamp 本地服务器中安装了 Laravel 5.4 最新版本。

我已经在我的 "Custom" 包中创建了以下文件，我正尝试在 Laravel 中注册：

packages/custom/timeshow/composer.json:

{
    "name": "custom/timeshow",
    "description": "Show Time in All Timezones",
    "type": "composer-plugin",
    "license": "GPL",
    "authors": [
        {
            "name": "Test Author",
            "email": "test1234@gmail.com"
        }
    ],
    "minimum-stability": "dev",
    "require": {},
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\": "app/",
            "Custom\Timeshow\": "packages/custom/timeshow/src"
        }
    }
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php -r \"copy('.env.example', '.env');\"",
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

packages\custom\timeshow\src\TimeshowServiceProvider.php

<?php

namespace Custom\Timeshow;

use Illuminate\Support\ServiceProvider;

class TimeshowServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        include __DIR__.'/routes.php';
        $this->app->make('Custom\Timeshow\TimeshowController');
    }
}

packages\custom\timeshow\src\TimeshowController.php

<?php
namespace Custom\Timeshow;

use App\Http\Controllers\Controller;
use Carbon\Carbon;

class TimeshowController extends Controller
{
    public function index($timezone)
    {
        echo Carbon::now($timezone)->toDateTimeString();
    }
}

packages\custom\timeshow\src\routes.php

<?php
Route::get('timeshow/{timezone}', 'Custom\Timeshow\TimeshowController@index');

还在 config/app.php 中包含我的服务提供商，如下所示：

Custom\Timeshow\TimeshowServiceProvider::class,

但即便如此，当我运行命令 php artisan serve 时，我仍收到以下错误：

[Symfony\Component\Debug\Exception\FatalErrorException]
  Class 'Custom\Timeshow\TimeshowServiceProvider' not found

谁能指出其中的错误并协助解决？

Answer 1

我认为您现在还不能在您的提供商上调用 app->make()。先在AppServiceProvier的register()方法中注册，如：

$this->app->register(Custom\Timeshow\TimeshowServiceProvider::class);

之后您应该能够从应用程序容器中解析它。或者您可以致电：

$this->app->singleton(Custom\Timeshow\TimeshowServiceProvider::class, function (Application $app) {
    return new TimeshowServiceProvider();
});

在您的包裹服务提供商内。我通常在我编写的包中绑定单例实例。

编辑

另一种想法，将您的包命名空间也添加到您的应用程序 composer.json：

"psr-4": {
    "Custom\Timeshow\": "packages/custom/timeshow/src"
}

将自定义包添加到 composer 后，您应该运行在命令下方

composer dump-autoload

和

php artisan optimize
