您究竟从哪里获得该示例？它看起来不完整。

只需将API调用的输出保存到某个变量，然后返回client_secretfor example：

$intent = $stripe->paymentIntents->create([
  'amount' => 1200,
  'currency' => 'usd',
  'payment_method_types' => ['card']
]);

$this->response([ 'success' =>'1' ,'status' => 'success', 'message' => $intent->client_secret], REST_Controller::HTTP_OK);
