消息”：“在邮递员上使用POST请求时，类App \\ Http \\ Requests \\ SignupRequest不存在

Question

1. 命名空间App \ Http \ Controllers;

   使用Illuminate \ Http \ Request;使用Illuminate \ Support \ Facades \ Auth; 使用App \ Http \ Controllers \ Controller;

   AuthController类扩展了控制器{

   public function __construct()
   {
       $this->middleware('auth:api', ['except' => ['login']]);
   }
   
   
   public function login(Request $request)
   {
       $credentials = $request->only('email', 'password');
   
       if ($token = $this->guard()->attempt($credentials)) {
           return $this->respondWithToken($token);
       }
   
       return response()->json(['error' => 'Unauthorized'], 401);
   }
   
   
   public function me()
   {
       return response()->json($this->guard()->user());
   }
   
   
   public function logout()
   {
        $this->guard()->logout();
   
        return response()->json(['message' => 'Successfully logged out']);
   }
   
   
   public function refresh()
   {
       return $this->respondWithToken($this->guard()->refresh());
   }
   
   
   protected function respondWithToken($token)
   {
       return response()->json([
           'access_token' => $token,
           'token_type' => 'bearer',
           'expires_in' => $this->guard()->factory()->getTTL() * 60
       ]);
   }
   
   /**
    * Get the guard to be used during authentication.
    *
    * @return \Illuminate\Contracts\Auth\Guard
    */
   public function guard()
   {
       return Auth::guard();
   } }
   

这是我从jwt官方网站上抄袭的代码，但遇到问题
