Laravel使用用户图像内置身份验证

Question

我使用的是Laravel内置的auth系统，可以在新的Laravel项目中运行php artisan make:auth命令轻松找到。 注册时，我也想给予用户上传他们个人资料图片的能力。

因此，我在注册表格中添加了一个名为profile_picture的新字段。 我如何从后端接收文件？ 我尝试将Request $request参数添加到数组$ data之后的create方法中，但是它说：

类型错误：传递给App \\ Http \\ Controllers \\ Auth \\ RegisterController :: create（）的参数1必须是Illuminate \\ Http \\ Request的实例，没有给出，在/ home / tawsif / laravel / repto_events / vendor / laravel /中调用第33行的framework / src / Illuminate / Foundation / Auth / RegistersUsers.php

寄存器控制器：

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;


class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after login / registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
            'profession' => 'required|min:3',
            'phone' => 'required|digits:11',
            'address' => 'required|min:5'
            // 'profile_picture' => 'required|image'
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(Request $request, array $data )
    {

         $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'phone' => $data['phone'],
            'ssc_year' => $data['ssc'],
            'hsc_year' => $data['hsc'],
            'profession' => $data['profession'],
            'address' => $data['address'],
        ]);

      $file = $request->file('profile_picture');
      $thumbnail_path = public_path('uploads/propic/thumbnail/');
      $original_path = public_path('uploads/propic/original/');
      $file_name = 'user_'. $user->id .'_'. str_rand(32) . '.' . $file->getClientOriginalExtension();
        Image::make($file)
              ->resize(261,null,function ($constraint) {
                $constraint->aspectRatio();
                 })
              ->save($original_path . $file_name)
              ->resize(90, 90)
              ->save($thumbnail_path . $file_name);

      $user->update(['profile_picture' => $file_name]);
      return $user;
    }
}

Answer 1

尝试将$ request移到第一个位置：

protected function create(Request $request, array $data)
    {
    .....

PS：如果返回用户创建的用户，则不起作用...或者仅是测试？，xD

Answer 2

添加新的__contruct方法，如下所示：

protected $request;

public function __contruct(Request $request)
{
    $this->request = $request;
}

并在您的创建方法中：

protected function create(Request $request, array $data )
    {

         $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'phone' => $data['phone'],
            'ssc_year' => $data['ssc'],
            'hsc_year' => $data['hsc'],
            'profession' => $data['profession'],
            'address' => $data['address'],
        ]);

      $file = $this->request->file('profile_picture');
      $thumbnail_path = public_path('uploads/propic/thumbnail/');
      $original_path = public_path('uploads/propic/original/');
      $file_name = 'user_'. $user->id .'_'. str_rand(32) . '.' . $file->getClientOriginalExtension();
        Image::make($file)
              ->resize(261,null,function ($constraint) {
                $constraint->aspectRatio();
                 })
              ->save($original_path . $file_name)
              ->resize(90, 90)
              ->save($thumbnail_path . $file_name);

      $user->update(['profile_picture' => $file_name]);
      return $user;
    }
