使用Sanctum API认证， 获取用户不稳定，刚登录是可以获取到的，多请求就此就获取不到了

auth.php

'guards' => [
    'web' => [
    'driver' => 'session',
    'provider' => 'users',
    ],
    'api' => [
    'driver' => 'sanctum',
    'provider' => 'sanctumUsers',
    ],
],

'providers' => [
  'users' => [
  'driver' => 'eloquent',
  'model' => App\Models\User::class,
  ],
  'sanctumUsers' => [
  'driver' => 'eloquent',
  'model' => App\Models\User::class,
  ],
],

route.php

Route::group([
  'middleware' => ['auth:api']
], function ($router) {
  //当前用户信息
  Route::get('user/info', 'UserController@info')->name('user.info');
  Route::post('user/changepw', 'UserController@changePw')->name('user.changepw');
  //用户退出
  Route::post('user/logout', 'UserController@logout')->name('user.logout');
});

UserController.php

public function login(Request $request)
{
    $data = $request->validate([
      'name' => 'required',
      'password' => 'required',
    ]);

    $user = User::query()->where('name', $request->name)->first();

    if (!$user || !Hash::check($request->password, $user->password)) {
    return response([
    'message' => ['用户名或者密码错误']
    ], 404);
    }

      $token = $user->createToken($request->device_name ?? 'pc')->plainTextToken;

    $response = [
        'user' => $user,
        'token' => $token
    ];

     return ResultHelper::json('200', 'success', $response);

}


public function info(Request $request)
{
  $user = $request->user('api');

  return ResultHelper::json('200', 'success', $user);
}

sanctum.php 这个文件没有改
