Dav*_*vid 4 php dependency-injection inversion-of-control laravel
我试图围绕依赖注入和IoC容器,我正在使用我的UserController作为示例.我正在定义UserController在其构造函数中所依赖的内容,然后使用App :: bind()将这些对象绑定到它.如果我正在使用Input :: get()facade/method/thing我没有利用我刚刚注入的Request对象?我是否应该使用以下代码,现在注入Request对象或者doInput :: get()解析为同一个Request实例?我想使用静态外墙,但如果他们决定解除未注入的物体,则不会.
$this->request->get('email');

依赖注入
<?php
App::bind('UserController', function() {
$controller = new UserController(
new Response,
App::make('request'),
App::make('view'),
App::make('validator'),
App::make('hash'),
new User
);
return $controller;
});

public function __construct(
Response $response,
\Illuminate\Http\Request $request,
\Illuminate\View\Environment $view,
\Illuminate\Validation\Factory $validator,
\Illuminate\Hashing\BcryptHasher $hasher,
User $user
){
$this->response = $response;
$this->request = $request;
$this->view = $view;
$this->validator = $validator;
$this->hasher = $hasher;
$this->user = $user;
}
public function index()
{
//should i use this?
$email = Input::get('email');
//or this?
$email = $this->request->get('email');
//should i use this?
return $this->view->make('users.login');
//or this?
return View::make('users.login');
