我有一个大约需要15秒的Web服务才能将JSON响应返回到front-end.My代码如下所示：
控制器代码：
public function getDetailReport($data){
$user_id = $data->user_id;
$test_id = $data->test_id;
$result_obj = new TestSetDetailResultTable();
$data_array = $result_obj->getDetailReportByUser($user_id, $test_id);
if($data_array['status'] == 1) {
echo $this->successMessage('successfully Executed',$data_array['record']);
} else {
echo $this->failMessage($data_array['error'],$data_array['message']);
}
exit;
}

我正在尝试调试此代码，但我不知道我在这里缺少什么。这需要15秒的时间才能返回响应？我做错了什么吗？
答案 0 :(得分：0)
当您调试而不是使用microtime（true）计算所需的时间时，我的猜测是例如DB查询：
$start=microtime(true);
$answer_list = $this->loadRowList($query);
$stop=microtime(true);
$neededTime=$stop-$start;
echo "Time for answer_list $neededTime s for query $query";
比你看到什么需要最长的时间。然后查看您的查询，查看您的数据库架构。在大多数情况下，您可以通过在db表上添加一些索引来解决该问题。你可以＆＃34;调试＆＃34;在sql级别上使用explain进行查询，这将显示您是否使用索引。
