我使用codeigniter 3为应用程序制作web服务。随机结果是一个致命的错误：
Severity: Core Warning --> Module 'tidy' already loaded Unknown 0
从我在日志中看到的内容看起来是两次请求。

START API CALL显示在控制器的构造函数中
END API显示在_return_output函数
中$this->output->set_header("Pragma: no-cache");
$this->output->set_header("Cache-Control: no-store, no-cache");
$this->output->set_status_header(200);
$this->output->set_content_type('application/json')->set_output(json_encode($content));
$this->output->_display();
log_message('debug', 'END API');
exit();
知道如何防止控制器被请求两次吗？
