使用 PHP 解析 BackupPC 的输出

Question

我尝试解析“BackupPC_serverMesg status Hosts”的输出。

我得到的输出：

Got reply: %Status = (" admin " => {"endTime" => "1645958205","activeJob" => 0,"state" => "Status_idle"},"192.168.1.50" => {"lastGoodBackupTime" => "1645944158","deadCnt" => 0,"reason" => "Reason_nothing_to_do","activeJob" => 0,"state" => "Status_idle","aliveCnt" => 1560,"endTime" => "","needLink" => 0,"startTime" => "1645970401","type" => "incr","userReq" => undef}," trashClean " => {"endTime" => "1642317435","activeJob" => 1,"state" => "Status_link_running"}," admin1 " => {"endTime" => "1645956676","activeJob" => 0,"state" => "Status_idle"});

我不知道如何解析它。 我需要来自“192.168.1.50”的所有内容。

你知道如何解决吗？

谢谢你的帮助

根据文档 https://backuppc.github.io/backuppc/ BackupPC_serverMesg 命令您始终会获得输出在 Perl hash 的文本版本中，您需要在 Perl 中进行 eval() ，然后只有您可以在 PHP 中获得 JSON 格式。

以下是主机的 cmd 输出之一：-

bin/BackupPC_serverMesg status jobs
bin/BackupPC_serverMesg status hosts
bin/BackupPC_serverMesg status info
bin/BackupPC_serverMesg status queues

我编写了一些代码来解析 PHP

<?php //php 7.2.24

$code = 'Got reply: %Status = (" admin " => {"endTime" => "1645958205","activeJob" => 0,"state" => "Status_idle"},"192.168.1.50" => {"lastGoodBackupTime" => "1645944158","deadCnt" => 0,"reason" => "Reason_nothing_to_do","activeJob" => 0,"state" => "Status_idle","aliveCnt" => 1560,"endTime" => "","needLink" => 0,"startTime" => "1645970401","type" => "incr","userReq" => undef}," trashClean " => {"endTime" => "1642317435","activeJob" => 1,"state" => "Status_link_running"}," admin1 " => {"endTime" => "1645956676","activeJob" => 0,"state" => "Status_idle"});';

// Let's fix this to JSON String 

$code = str_replace('Got reply: %Status = ','',$code);
$code = str_replace('(','{',$code);
$code = str_replace(')','}',$code);
$code = str_replace('=>',':',$code);
$code = str_replace(';','',$code);
$code = stripslashes($code);
$code = str_replace('" ', '"',$code);
$code = str_replace(' "', '"',$code);
$code = str_replace('undef', '"undef"',$code);
$code = trim($code);

$data = json_decode($code, true);

print_r($data["192.168.1.50"]);

?>

输出中的此输出字符串：

Array
(
    [lastGoodBackupTime] => 1645944158
    [deadCnt] => 0
    [reason] => Reason_nothing_to_do
    [activeJob] => 0
    [state] => Status_idle
    [aliveCnt] => 1560
    [endTime] => 
    [needLink] => 0
    [startTime] => 1645970401
    [type] => incr
    [userReq] => undef
)

此外，要在 Perl 中对日志的所有输出进行此解析，请检查此存储库代码 https://github.com/plepe/backuppc-print-status/blob/master/backuppc-status-json
