Laravel 5.5 Api Registration issue - laravel

Question

I have been trying to get this api up and running and keep on experiencing this error when I test in Postman.
1. api.php
Route::group(['middleware' => ['api','cors']], function () {
Route::post('auth/register', 'Auth\RegisterController#create');
});
2. RegisterController
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}}
Postman configuration set to Post, the body is set to raw and JSON(application/json) Below is the postman json code.
{
"name": "Walter White",
"email": "wwhite#someemaildomain.net",
"password": "testpassword"
}
Below is the error
Too few arguments to function App\Http\Controllers\Auth\RegisterController::create(), 0 passed and exactly 1 expected in file C:\xampp\examplestuff

Answer 1

In order to fix your registration you should change your route definition to:
Route::group(['middleware' => ['api','cors']], function () {
Route::post('auth/register', 'Auth\RegisterController#register');
});
I assume your RegisterController is using the trait RegistersUsers. This trait is providing the register method, which is using the RegisterController::create method to create the new user itself.

Answer 2

Pass Request to your create function like:
protected function create(Request $request){...
and access your data like this:
$request->name

Answer 3

you have to do validation also plz check below answer
protected function create(Request $request)
{
$data = $request->json()->all();
$validator = Validator::make($data, [
'name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:6|confirmed',
]);
if ($validator->fails()) {
foreach ($validator->messages()->getMessages() as $field_name => $message){
$messages[] = $message[0];
}
$messages = $messages;
$message = implode(',',$messages);
$response = $messages;
return $response;
}else{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}
}
