Question

您好我正在尝试从用户对象生成令牌，如下所示：

<?php
namespace App\Http\Controllers\API\Auth;

use App\Models\User;
use App\Http\Controllers\Controller;
use Auth;
use Response;

class LoginController extends Controller
{
    public function login() { 
        $content = [];
        if(Auth::attempt(['email' => request('username'), 'password' => request('password')])){
            $user = Auth::user();
            $role = $user->roles()->first()->name;
            $content['access_token'] = $user->createToken('Token Name')->accessToken;
            $status = 200;
        }
        else{
            $content['error'] = "Unauthorised";
            $content['message'] = "Your email or password are incorrect";
            $status = 401;
        }
        return response()->json($content, $status); 
    }
}

我收到500服务器错误：

Trying to get property of non-object

我在User模型上有HasApiTokens，并且使用内置的Passport路由生成令牌没有问题。

这是Stack Trace的第一部分：

Answer 1

尝试使用以下命令创建客户端ID和密码： php artisan护照：客户

了解更多详情： https://laravel.com/docs/5.6/passport#client-credentials-grant-tokens

Answer 2

护照安装可能有问题。

尝试一下： php artisan护照：安装--force

Answer 3

这可能已经晚了，但是为了那些遇到类似问题的人，

运行后，将“ client-id”替换为Client ID的值

php artisan passport:client --personal.

如此

Passport::personalAccessClientId('client-id');

应替换为Passport::personalAccessClientId('4'); //其中4是生成的客户端ID //此代码位于AuthServiceProvider的boot（）函数中
