Lumen使用tideways加中间件记录慢接口以及对应接口执行的SQL

先上代码：

<?php

namespace App\Http\Middlewares;

use Closure;
use Illuminate\Support\Facades\DB;

class ProfilerMiddleware
{
    public function handle($request, Closure $next)
    {
        $extension = extension_loaded('tideways');

        if (! $extension) {
            return $next($request);
        }

        tideways_enable(TIDEWAYS_FLAGS_CPU | TIDEWAYS_FLAGS_MEMORY);
        
        $begin = microtime(true);

        $query = [];
        DB::listen(function ($sql) use (&$query){
            $bindings = $sql->bindings;
            foreach ($bindings as $i => $binding) {
                if ($binding instanceof \DateTime) {
                    $bindings[$i] = $binding->format('\'Y-m-d H:i:s\'');
                } else {
                    if (is_string($binding)) {
                        $bindings[$i] = "'$binding'";
                    }
                }
            }

            // Insert bindings into query
            $tmpQuery = str_replace(['%', '?'], ['%%', '%s'], $sql->sql);

            $query[] = vsprintf($tmpQuery, $bindings);
        });
        $result = $next($request);
        $end = microtime(true);

        if ($end - $begin > env('APP_MAX_RESPONSE_TIME', 1)) {
            $dir = storage_path('logs');
            $file = 'profiler.' . route_name() . '.log';
            $content = json_encode(tideways_disable());

            file_put_contents($dir . '/' . $file, $content);

            // Save the query to file
            $logFile = fopen(storage_path('logs' . DIRECTORY_SEPARATOR . 'slow-db-query-' . date('Y-m-d') . '.log'), 'a+');
            foreach ($query as $item){
                fwrite($logFile, date('Y-m-d H:i:s') . ': ' . $item . PHP_EOL);
            }
            fclose($logFile);
        }

        return $result;
    }
}

代码解释：

• 使用tideways扩展+中间件记录执行慢的接口和请求分析所需数据：首先lumen中的中间件会在执行代码中的$next($request)后，执行后续的全部操作，最终$result变量存储的是最终的response，而tideways是php分析代码执行的扩展
• 使用DB监听记录执行的SQL，并记录
