User Authentication in Lumen

问题

I'm trying to enable basic user authentication username, and password into my Lumen application.

In app.php file, the following has been uncommented as explained in https://lumen.laravel.com/docs/5.4/authentication

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

My Route looks like this:

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

My Controller looks like this:

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'];
}
}

I have been getting a combination of weird and wonderful errors, currently I'm getting:

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

I've done some extensive google searching, but there doesn't seem to be many documented uses of user auth in Lumen so looking for a pointer as to what I've missed here.

My initial error: I was looking for a method of logging in a user, what I should have been looking for was authentication. Thinking about what I actually needed to achieve I came up with the below functions:

1. Create user
2. Delete user
3. Verify user

With that in mind I ended up with something like the below:

<?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);
    }

}

I'm not really sure what you want to achieve with UserRepository and Auth. Lumen is a stateless framework, meaning that Auth::login() never will have any effect. Also, as far as I'm concerned, UserRepository is a Laravel thing. Not a Lumen thing.

Create the user with App\User::create($request->all()) and access it through the Eloquent model. You can enable Eloquent in bootstrap/app.php
