yii怎么记录api接口执行时间

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("%s\n\tmemory 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' => 'yii\log\FileTarget',
    'levels' => ['info'],
    'categories' => ['debug', 'sql', 'elastic', 'py'],
    'logVars' => [],
    'logFile' => '@runtime/logs/info.log'
]
