如何使用Repository模式

某天，你无端想起一个人，她曾让你对明天有所期许，但是却完全没有出现在你的明天里。
这里我们介绍一种laravel开发的模式,用于解决控制器过于肥大的问题.

路由 routes.php

<?php
Route::get('/user', 'UserController@getUser');

控制器 app\Http\Controllers\UserController.php

将新建的库依赖注入

<?php

namespace App\Http\Controllers;

use App\Repository\UserRepository;

class UserController extends Controller
{
    protected $userRepository;

    public function __construct(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function getUser()
    {
        return $this->userRepository->getUser();
    }
}

模型 app\User.php

<?php

namespace App;

use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

新建库 app\Repository\UserRepository.php

class UserRepository
{
    protected $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function getUser()
    {
        return $this->user->all();
    }
    
}
