php - 如何修复 laravel 中的 JWT 身份验证错误？

Question

我正在设计登录 api，当我尝试签入邮递员时，它会引发错误，TypeError：传递给 Tymon\JWTAuth\JWT::fromUser() 的参数 1 必须是 Tymon\JWTAuth\Contracts\JWTSubject 的实例，App 的实例\Models\User 给定，我在 .env 中设置所有警卫、提供者密钥，并且发布也已完成，请帮我解决这个问题。 Error when i am trying to login

 TypeError: Argument 1 passed to Tymon\JWTAuth\JWT::fromUser() must be an instance of Tymon\JWTAuth\Contracts\JWTSubject, instance of App\Models\User given, called in C:\Users\VICKY\Desktop\8\laravel-bookstore\vendor\tymon\jwt-auth\src\JWTAuth.php on line 54 in file C:\Users\VICKY\Desktop\8\laravel-bookstore\vendor\tymon\jwt-auth\src\JWT.php on line 88
