记录 phpflo 网络执行以进行调试或分析。

跟踪事件

每次您想要调试您的流程时，您都需要查看您组件之间数据转换，连接/断开等。

使用这个库，您现在可以这样做。

设置

它几乎与使用 phpflo 本身一样简单。添加 composer require phpflo/flowtrace 并初始化如下

<?php
require __DIR__ . '/../../vendor/autoload.php';

$traceableNetwork = new \PhpFlo\FlowTrace\TraceableNetwork(
    new PhpFlo\Core\Network(
        new PhpFlo\Core\Builder\ComponentFactory()
    ),
    new \PhpFlo\FlowTrace\Logger\SimpleFile(__DIR__ . DIRECTORY_SEPARATOR . 'flow.log', 'info')
);
$traceableNetwork
    ->boot(__DIR__.'/count.fbp')
    ->run($fileName, "ReadFile", "source")
    ->shutdown();

这将把所有您的数据流程输出到 flow.log 中，您可以在以后进行审查。如您所注意到的，日志记录器有一个“级别”给出，这是 PSR3 兼容的——事实上，整个 SimpleFile 日志记录器只是 PSR3 AbstractLogger 的基本实现。您可以轻松地将此日志记录器替换为您自己的 PSR 兼容版本。提供一定级别将为您提供更多详细信息。“debug”将提供所有连接/断开，而“info”只提供数据流和数据。

日志

日志与 flowbased/flowtrace 兼容，并在 Flowhub 中重现流程。
