无法在 Codeigniter4 中触发 ChromeLogger 处理程序

Question

我是php及其框架的新手。我遵循了有关如何在Logger.php中添加ChromeLogger的官方指南。我还为Chrome Logger添加了chrome扩展程序。

如何查看控制器上的任何日志记录信息？

记录器.php

<?php
namespace Config;
use CodeIgniterConfigBaseConfig;
class Logger extends BaseConfig
{
...
public $handlers = [
//--------------------------------------------------------------------
// File Handler
//--------------------------------------------------------------------
'CodeIgniterLogHandlersFileHandler' => [
/*
* The log levels that this handler will handle.
*/
'handles'         => [
'critical',
'alert',
'emergency',
'debug',
'error',
'info',
'notice',
'warning',
],
/*
* Leave this BLANK unless you would like to set something other than the default
* writeable/logs/ directory. Use a full getServer path with trailing slash.
*/
'path'            => WRITEPATH . 'logs/',
/*
* The default filename extension for log files. The default 'php' allows for
* protecting the log files via basic scripting, when they are to be stored
* under a publicly accessible directory.
*
* Note: Leaving it blank will default to 'php'.
*/
'fileExtension'   => 'php',
/*
* The file system permissions to be applied on newly created log files.
*
* IMPORTANT: This MUST be an integer (no quotes) and you MUST use octal
* integer notation (i.e. 0700, 0644, etc.)
*/
'filePermissions' => 0644,
],
/**
* The ChromeLoggerHandler requires the use of the Chrome web browser
* and the ChromeLogger extension. Uncomment this block to use it.
*/
'CodeIgniterLogHandlersChromeLoggerHandler' => [
/*
* The log levels that this handler will handle.
*/
'handles' => [
'critical', 'alert', 'emergency', 'debug',
'error', 'info', 'notice', 'warning'
],
]
];
}

新闻.php

<?php
namespace AppControllers;
use AppModelsNewsModel;
use CodeIgniterController;

class News extends Controller
{
public function index()
{
log_message('info', 'News Index page is visited');
$model = new NewsModel();
$data = [
'news'  => $model->getNews(),
'title' => 'News archive',
];
echo view('templates/header', $data);
echo view('news/overview', $data);
echo view('templates/footer');
}
}

Answer 1

首先在app\Config\Logger.php中检查您的阈值：

public $threshold = 4;

出厂默认值为 4，但要记录"信息"级别的消息$threshold应为 7！

其次，您可以验证您的服务器是否正在浏览器开发工具(网络 -> 标头 -> 响应(中发送 ChromeLogger 数据。页眉：

X-ChromeLogger-Data：...

应该包括在内。

第三，看起来原始的ChromeLogger扩展程序在Chrome中不起作用，但在Firefox中运行良好。日志消息应位于开发工具控制台中。

我安装了这个扩展程序：

服务器日志 作者：拉斯穆斯·舒尔茨

它的工作原理是在新的开发工具选项卡"服务器日志"中添加日志信息。 它还支持新的日志标头X-ServerLog-Location。
