在 basecontroller 中继承父类的 beforeaction 和 afteraction 勾子，记录api运行开始，以及结束时间。
示例：
private $actionStart = 0; private $actionEnd = 0; // beforeAction, afterAction 用来记录API请求接口，以及耗时 public function beforeAction($action){ $this->actionStart = microtime(true); return parent::beforeAction($action); } public function afterAction($action, $result){ $this->actionEnd = microtime(true); $afterAction = parent::afterAction($action, $result); // 记录API请求接口，耗时took logInfo(print_r(["api" => request()->url, "took" => sprintf("%.5f", $this->actionEnd - $this->actionStart)], true)); return $afterAction;}
（推荐教程：yii框架）
logInfo 日志记录方法，这个方法是对 YII info日志的二次封装
// yii日志组件记录日志if (!function_exists("logInfo")) { function logInfo($message, $category = "debug") { // 记录info日志，用于调试 $logEnable = Yii::$app->params["log_enable"]; if (is_null($logEnable) || $logEnable === false) { return; } Yii::info(sprintf("%sntmemory used %d bytes [%.3f KB]", $message, memory_get_usage(), memory_get_usage()/1024), $category); }}
日志输出如下：
2019-03-14 02:46:31 [127.0.0.1][-][-][info][debug] Array ( [api] => /protocol?page=1&limit=12&unit=10m&time[]=1551854884755&time[]=1552459684755&q=&es_type=http&src_ip=&src_port=&dst_ip=&dst_port=&sensor_id=&uids=&prs_debug=1 [took] => 0.18194 ) memory used 8996368 bytes [8785.516 KB] in /Users/tophant.yunfei/work/prs-rebirth-php/common/utils/function.php:316 in /Users/tophant.yunfei/work/prs-rebirth-php/backend/controllers/RestBaseController.php:61
Yii-log 配置如下：
[ 'class' => 'yiilogFileTarget', 'levels' => ['info'], 'categories' => ['debug', 'sql', 'elastic', 'py'], 'logVars' => [], 'logFile' => '@runtime/logs/info.log' ]
