在app/Http/Kernel.php下$middleware加入下面代码

\Guandeng\Tracer\Middleware\TraceMiddleware::class

配置config/opentracing.php

<?php

declare(strict_types=1);

use Zipkin\Samplers\BinarySampler;

return [
    'default' => env('TRACER_DRIVER', 'zipkin'),
    'middleware' => [
        'excluded_paths' => env('TRACER_EXCLUDED_PATHS', ''), // 路径黑名单
        'included_paths' => env('TRACER_INCLUDED_PATHS', null), // 路径白名单

use Guandeng\Tracer\Listeners\RpcListener;

$subscriber = new RpcListener();
// $name 定义的Span名称, $request  
$subscriber->onJobProcessing($request);// 监听开始

// your code

$subscriber->onJobProcessed();// 监听结束
