How can I write this laravel syntax error?

Use the Registry ticket that comes with laravel5.2 to add a verification code entry to it and submit the Verification Code together with the original form. The controller verification method is as follows: {code ...} because a verification code is added, it becomes like this: 1. A Request $ request parameter is added; 2. A line is added... use the Registry ticket provided by laravel5.2 to add a verification code entry to it and submit the Verification Code together with the original form. The controller verification method is as follows:

protected function validator(array $data){    return Validator::make($data, [        'name' => 'required|max:255',        'email' => 'required|email|max:255|unique:users',        'password' => 'required|confirmed|min:6',            ]);}

This is because a verification code is added:
1. addedRequest $requestParameters;
2. added a line of code.$verification_code_session = $request->session()->get('verification_code', '');)

protected function validator(array $data,Request $request){    $verification_code_session = $request->session()->get('verification_code', '');    return Validator::make($data, [        'name' => 'required|max:255',        'email' => 'required|email|max:255|unique:users',        'password' => 'required|confirmed|min:6',        'verification_code' => 'required|in:' . $verification_code_session    ]);

The error message is as follows:

Type error: Argument 2 passed to App\Http\Controllers\Auth\AuthController::validator() must be an instance of Illuminate\Http\Request, none given, called in D:\wnmp\www\laravel-entrust\vendor\laravel\framework\src\Illuminate\Foundation\Auth\RegistersUsers.php on line 69

In short, the parameter syntax is incorrect. I don't know how to write the syntax. Let's take a look.

Do not inject the Request class in the form of dependency injection.

Directly

$verification_code_session = Request::session()->get('verification_code', '');

Write on mobile phone, just understand what it means

Besides static callsRequest::session()(Facade) and direct callrequest()->session()(Helper), if you must use dependency injection, you must put the parameters that require dependency injection in front of the brackets, as shown below:

protected function validator(Request $request, array $data){    //...}
