php - Laravel 如何使用 auth :user() 返回选定的列

Question

这几天开始用Passport学习Laravel，关注了这篇精彩的文章Create REST API in Laravel with authentication using Passport .

我已经创建了登录、注册、详细信息列表 API，但在登录 API 中，我试图以 JSON 格式返回登录的用户详细信息，它返回所有信息，但我只想要 id, name, email, phone那么如何申请select('id', 'name', 'email', 'phone')在 $user = Auth::user()
我可以使用 PHP unset 函数轻松删除数据，但我不想使用它。我只想选择需要的列，所以有可能吗？

我的 Controller 源代码:

<?php

namespace App\Http\Controllers\API;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\User;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Validator;

class PassportController extends Controller
{
    public function login()
    {
        if (Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
            $user = Auth::user();
            $success['token'] = $user->createToken('MyApp')->accessToken;

            return response()->json(['data' => $user, 'success' => $success], 200);
        } else {
            return response()->json(['error' => 'Unauthorised'], 401);
        }
    }
}

API JSON 结果:

{
    "data": {
        "id": 1,
        "name": "Abraham Hess",
        "first_name": "Abraham",
        "last_name": "Hess",
        "phone": "982595360",
        "email": "abraham@mailinator.com",

        "updated_at": "2018-05-29 16:58:55"
    },
    "success": {

你可以用 ->only 来做:

return response()->json([
    'data' => $user->only(['id', 'name', 'phone', 'email']),
    ...
]);
