如何在 laravel 5 中解析带有 make 参数的控制器?

How to resolve a controller with make parameter in laravel 5?

以前我可以这样做:

/var/www/laravel/app/Http/Controllers/HelloController.php

<?php namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Models\Hello\Hello as Hello;

class HelloController extends Controller {
    public function index() {

        $o = new Hello;

        $o = new Hello('changed1','changed1');

        var_dump($o);
    }
}

/var/www/laravel/app/Models/Hello

<?php namespace App\Models\Hello;

use Illuminate\Database\Eloquent\Model\Hello.php;


class Hello extends Model
{
    public function __construct($one='default1', $two='default2')
    {
        echo "First  Param: $one","\n<br>\n";
        echo "Second Param: $two","\n<br>\n";
        echo "\n<br>\n";
    }
}

routes.php

Route::get('tutorial', function() {
    $app = app(); 
    $app->make('Hello');
});

无需 make 即可实例化,但这会带来错误:

ReflectionException in Container.php line 776: Class Hello does not exist

你认为我在这里缺少什么?

因为您的 class 具有 App\Models\Hellonamespace,您必须在尝试实例化 class 时使用它的 namespace。因此,你的代码应该是这样的:

Route::get('tutorial', function() {
    $app = app(); 
    $app->make('App\Models\Hello\Hello');
});

为了在答案中扩展一点,您可以删除 make() 方法调用并只使用 app() 帮助程序,您最终会得到相同的结果:

Route::get('tutorial', function() {
    $app = app(); 
    $app->make('App\Models\Hello\Hello');

    // you can achieve the same with the
    // `app()` helper using less characters :)
    app('App\Models\Hello\Hello');
});
