Lumen 中的用户身份验证答案

【问题标题】：User Authentication in LumenLumen 中的用户身份验证
【发布时间】：2017-09-11 14:05:42
【问题描述】：

我正在尝试在我的 Lumen 应用程序中启用基本用户身份验证 username 和 password。

在app.php 文件中，如https://lumen.laravel.com/docs/5.4/authentication 中所述，以下内容已取消注释

 $app->withFacades();
 $app->routeMiddleware([
    'auth' => App\Http\Middleware\Authenticate::class,
 ]);
  $app->register(App\Providers\AuthServiceProvider::class);

我的路线如下所示：

 $app->post('auth/register', ['uses' => 'Auth\AuthController@postRegister']);

我的控制器如下所示：

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Repositories\UserRepository;
use Illuminate\Http\Request;
use Auth;
use App\User;
 class AuthController extends Controller {

/**
 * Create a new authentication controller instance.
 *
 * @return void
 */
public function __construct()
{

}

public function postRegister(Request $request, UserRepository $userRepository)
{
    $this->validate($request, [
        'name' => 'required|max:255',
        'email' => 'required|email|max:255|unique:users',
        'password' => 'required|confirmed|min:6',
    ]);

    $user = $userRepository->store($request);

    Auth::login($user);

    return ['result' => 'success'];
}
}

我遇到了一些奇怪而奇妙的错误，目前我得到的是：

ReflectionException in BoundMethod.php line 155:
Class App\Repositories\UserRepository does not exist

我已经进行了一些广泛的谷歌搜索，但 Lumen 中用户身份验证的使用记录似乎并不多，因此寻找关于我在这里错过的内容的指针。

【问题讨论】：

您需要缩小问题范围。那么UserRepository类没有被服务容器解析？仔细检查你是否没有在类名或路径上犯任何错误。

我最初的错误：我正在寻找一种登录用户的方法，我应该寻找的是身份验证。考虑到我实际需要实现什么，我想出了以下功能：

创建用户
删除用户
验证用户

考虑到这一点，我最终得到了如下内容：

<?php
namespace App\Http\Controllers\Auth;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
//Required to hash the password
use Illuminate\Support\Facades\Hash;

class AuthController extends Controller {
    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {

    }

    public function validateRequest(Request $request) {
      $rules = [
          'email' => 'required|email|unique:users',
          'password' => 'required|min:6'
      ];
      $this->validate($request, $rules);
    }


    //Get the input and create a user
    public function store(Request $request) {
        $this->validateRequest($request);
        $user = User::create([
            'email' => $request->get('email'),
            'password'=> Hash::make($request->get('password'))
        ]);
        return response()->json(['status' => "success", "user_id" => $user->id], 201);
    }


   //delete the user
   public function destroy($id) {
          $user = User::find($id);
          if(!$user){
              return response()->json(['message' => "The user with {$id} doesn't exist"], 404);
          }
          $user->delete();
          return response()->json(['data' => "The user with with id {$id} has been deleted"], 200);
        }


    //Authenticate the user
    public function verify(Request $request) {
      $email = $request->get('email');
      $password = $request->get('password');
      $user = User::where('email', $email)->first();
      if($user && Hash::check($password, $user->password)) {
        return response()->json($user, 200);
      }
      return response()->json(['message' => "User details incorrect"], 404);
    }


    //Return the user
    public function show($id) {
      $user = User::find($id);
      if(!$user) {
        return response()->json(['status' => "invalid", "message" => "The userid {$id} does not exist"], 404);
      }
        return response()->json(['status' => "success", 'data' => $user], 200);
    }

    //Update the password
    public function update(Request $request, $id) {
      $user = User::find($id);
      if(!$user){
          return response()->json(['message' => "The user with {$id} doesn't exist"], 404);
      }
      $this->validateRequest($request);
      $user->email        = $request->get('email');
      $user->password     = Hash::make($request->get('password'));
      $user->save();
      return response()->json(['data' => "The user with with id {$user->id} has been updated"], 200);
    }

}

【解决方案2】：

我不太确定你想用 UserRepository 和 Auth 实现什么。 Lumen 是一个无状态框架，这意味着Auth::login() 永远不会有任何影响。另外，就我而言，UserRepository 是 Laravel 的东西。不是流明的事情。

使用App\User::create($request->all()) 创建用户并通过 Eloquent 模型访问它。你可以在bootstrap/app.php启用Eloquent
