如何像格式数组一样用monolog记录多行条目? [英] How to log multiline entries with monolog like a formatted array?

问题描述

我正在尝试在symfony中用monolog记录一个数组.

I am trying to log an array with monolog in symfony.

$logger = $this->get('logger');
$logger->info(=print_R($user,true));

我得到的输出未格式化为预期的print_r.它全部记录在一行上.

the output i get is not formatted as a print_r would be expected. It logs it all on one line.

我的config.yml中没有任何独白设置，并且怀疑这可能是问题所在.

I do not have any monolog settings in my config.yml and suspect this may be the issue.

如何使用独白记录print_r(array)，以便它以tail -f格式显示?

How can I log a print_r(array) using monolog so it displays formatted in a tail -f?

推荐答案

Monolog默认使用Monolog\Formatter\LineFormatter，不带任何参数.格式化程序基本上是负责最终输出日志的对象.查看构造函数定义:

Monolog uses Monolog\Formatter\LineFormatter by default without any arguments. Formatter is basically object that is responsible for final output in your logs. Look at constructor definition:

public function __construct($format = null, $dateFormat = null, $allowInlineLineBreaks = false, $ignoreEmptyContextAndExtra = false)

如您所见，由于第三个参数，LineFormatter从print_r输出创建了一行.您需要使用LineFormatter的自定义参数定义新服务.

As you can see LineFormatter creates one line from your print_r output because of third argument. You need to define new service with custom arguments for LineFormatter.

# app/config/services.yml - for example
services:
    monolog.my_line_formatter: # Your name
        class: Monolog\Formatter\LineFormatter
        arguments: [~, ~, true]

现在找到您的独白定义并使用格式化程序满足您的需求.

Now find your monolog definition and use formatter for what you need.

# Example from default config_dev.yml
monolog:
    handlers:
        main:
            type:   stream
            path:   "%kernel.logs_dir%/%kernel.environment%.log"
            level:  debug
            formatter: monolog.my_line_formatter
