【问题描述】：

我使用本指南制作 jwt-auth https://medium.com/mesan-digital/tutorial-4-how-to-build-a-laravel-5-4-jwt-powered-mobile-app-api-4c59109d35f 当我尝试注册用户时，我发现了这个问题。这是 composer.json 的要求

  "require": {
        "php": ">=7.1.3",
        "fideloper/proxy": "~4.0",
        "laravel/framework": "5.5.*",
        "laravel/tinker": "~1.0",
        "tymon/jwt-auth": "1.0.0-rc.1"
    },

这里是 user.php "

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Tymon\JWTAuth\Contracts\JWTSubject;

class User extends Authenticatable implements JWTSubject
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
    /**
     * Get the identifier that will be stored in the subject claim of the JWT.
     *
     * @return mixed
     */
    public function getJWTIdentifier()
    {
        return $this->getKey();
    }
    /**
     * Return a key value array, containing any custom claims to be added to the JWT.
     *
     * @return array
     */
    public function getJWTCustomClaims()
    {
        return [];
    }
}"

【问题讨论】：

如果你在命令行中运行composer show tymon/jwt-auth会得到什么？
以防万一，运行composer dump-autoload
什么也没发生：(
@IonMîndru 你解决了吗？

标签： php laravel jwt-auth

【解决方案1】：

我认为你应该看看这个thread，用这个依赖更新你的composer.json：

"tymon/jwt-auth": "^1.0.0-beta.3@dev"

然后运行composer update。
