有没有办法在日志中保存 Info + Errors 而无需调试？
调试级别如何显示信息？
如果我想记录信息“帐户 ID 4345 已被管理员删除”，为什么我需要查看所有这些:

谢谢

最佳答案

你不会在 codeigniter 2 中遇到这个问题

$config['log_threshold'] = array(1, 3);

在 config/config.php 中

和

log_message('info', 'The purpose of some variable is to provide some value.');

你想记录的地方只会将该消息打印到日志文件，没有多余的调试代码。

但是

在codeIgniter 3中，很多系统核心文件都有

log_message('info', ******************);

喜欢

log_message('info', 'Config Class Initialized');
log_message('info', 'Controller Class Initialized');
log_message('info', 'Hooks Class Initialized');
............

这就是为什么

$config['log_threshold'] = array(1, 3);

或

$config['log_threshold'] = array(3);

或

$config['log_threshold'] = 3;

然后所有不需要的日志消息都出现在日志文件中。

因此，解决此问题的一种方法是扩展所有核心文件并进行更改

log_message('info'

到

log_message('debug' 

或者创建一个新的阈值，比如

在 config/config.php 中

$config['log_threshold'] = array(1, 5);

在核心/MY_Log.php

protected $_levels = array('ERROR' => '1', 'DEBUG' => '2', 'INFO' => '3', 'ALL' => '4', 'USER_INFO' => '5');

完整的核心/MY_Log.php 文件

class MY_Log extends CI_Log

    protected $_log_path;
    protected $_threshold = 1;
    protected $_date_fmt = 'Y-m-d H:i:s';
