User Authentication in Lumen - php

Question

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:
Create user
Delete user
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
