如何让用户在 Laravel 7.x 中更改自己的密码？

Question

有numerousposts关于如何允许用户更改密码，但其中许多是针对旧版本的 Laravel。 2020年Laravel v7.x的正确做法是什么？

Answer 1

首先，让我们为用户创建一个表单。

关于此表格的几点说明：

• 我使表单尽可能简单以使其可读 - CSRF 令牌由 Form::open 自动创建

• 您应该只使用“密码”作为密码管理员应该自动填充的字段名称。一些答案建议使用“密码”作为新密码字段名称，这会造成非常糟糕的用户体验

  {{Form::open(array('url' => '/account/change-password'))}}
  <input type="hidden" name="_token" value="{{ csrf_token() }}">
  
  <div class="form-group">
  
      <div class="row">
          <div class="col">
              <label for="password" class="control-label">Current Password</label>
          </div>
          <div class="col">
              {{Form::password('password', array('id' => 'password', 'class' => 'form-control', 'placeholder' => 'Password'))}}
          </div>
      </div>
  </div>
  
  <div class="form-group">
      <div class="row">
          <div class="col">
              <label for="new-password" class="control-label">New Password</label>
          </div>
          <div class="col">
              {{Form::password('new-password', array('id' => 'new-password', 'class' => 'form-control', 'placeholder' => 'New Password'))}}
          </div>
      </div>
  </div>
  
  <div class="form-group">
      <div class="row">
          <div class="col">
              <label for="new-password-confirmation" class="control-label">Re-enter
                  Password</label>
          </div>
          <div class="col">
              {{Form::password('new-password-confirmation', array('id' => 'new-password-confirmation', 'class' => 'form-control', 'placeholder' => 'Confirm Password'))}}
          </div>
      </div>
  </div>
  
  <div class="form-group">
      <button type="submit" class="btn btn-danger">Change Password</button>
  </div>
  {{Form::close()}}
  

现在在您要处理请求的控制器中，让我们更改密码。

关于此的几点说明：

• 我们确认密码不是通用密码 - 此处使用的列表并非详尽无遗（全部小写），我建议您使用等于或大于您的最小长度的 the common passwords 更新它
• 说到最小长度，8 个字符应该是你在这个时代的起点
• 最后，不要验证密码确认的长度 - 它只会给你两个错误（因为它已经完成了）
• 最后，这不会审核密码更改。使用 Laravel Auditing 之类的东西，甚至只是发送电子邮件。

Account.php

use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Validation\Rule;

 /**
 * Change users password
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\RedirectResponse
 */
public function changePassword(Request $request)
{
    if(Auth::Check())
    {
        $requestData = $request->All();
        $validator = $this->validatePasswords($requestData);
        if($validator->fails())
        {
            return back()->withErrors($validator->getMessageBag());
        }
        else
        {
            $currentPassword = Auth::User()->password;
            if(Hash::check($requestData['password'], $currentPassword))
            {
                $userId = Auth::User()->id;
                $user = User::find($userId);
                $user->password = Hash::make($requestData['new-password']);;
                $user->save();
                return back()->with('message', 'Your password has been updated successfully.');
            }
            else
            {
                return back()->withErrors(['Sorry, your current password was not recognised. Please try again.']);
            }
        }
    }
    else
    {
        // Auth check failed - redirect to domain root
        return redirect()->to('/');
    }
}

/**
 * Validate password entry
 *
 * @param array $data
 * @return \Illuminate\Contracts\Validation\Validator
 */
public function validatePasswords(array $data)
{
    $messages = [
        'password.required' => 'Please enter your current password',
        'new-password.required' => 'Please enter a new password',
        'new-password-confirmation.not_in' => 'Sorry, common passwords are not allowed. Please try a different new password.'
    ];

    $validator = Validator::make($data, [
        'password' => 'required',
        'new-password' => ['required', 'same:new-password', 'min:8', Rule::notIn($this->bannedPasswords())],
        'new-password-confirmation' => 'required|same:new-password',
    ], $messages);

    return $validator;
}

/**
 * Get an array of all common passwords which we don't allow
 *
 * @return array
 */
public function bannedPasswords(){
    return [
        'password', '12345678', '123456789', 'baseball', 'football', 'jennifer', 'iloveyou', '11111111', '222222222', '33333333', 'qwerty123'
    ];
