php json解码奇怪的格式

Question

我正在尝试解码来自我的 IP 警报系统的一些数据。我被告知数据是 json，并且查看 html 文件，有对 json 的引用。问题是它看起来有点奇怪:-)

以下是警报的原始输出：

/*-secure- {    senrows : [ {no : "1", type : "Door Contact", zone : "1", name : "zone1", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "2", type : "Door Contact", zone : "2", name : "zone2", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "3", type : "Door Contact", zone : "3", name : "zone3", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "4", type : "Door Contact", zone : "4", name : "zone4", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "5", type : "Door Contact", zone : "5", name : "zone5", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "6", type : "Door Contact", zone : "6", name : "zone6", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "7", type : "Door Contact", zone : "7", name : "zone7", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "8", type : "Door Contact", zone : "8", name : "zone8", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "9", type : "Door Contact", zone : "9", name : "zone9", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "10", type : "IR Sensor", zone : "10", name : "zone10", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "11", type : "Remote Keypad", zone : "11", name : "zone11", attr : "",cond : "", battery : "", tamp : "", bypass : "No"}] } */

如何解码这个数据？？ :-)

json_decode() 不起作用：-/

Answer 1

嗯，你仍然应该首先要求给你这个输出的人修复他们的代码并实际交付 JSON。

不过，我还是有几分钟的时间享受编码练习，为您的数据编写快速修复程序。
它仅在您的代码始终以相同的 -secure- 开头时才有效，否则您必须对其进行调整。

如果由于某种原因你有一个包含封装字符串的字段，比如 a:"text\"moretext\"finaltext"，或者如果提供者引入任何其他错误，它将失败或产生奇怪的结果除了你的例子中显示的那些。

<?php
$data = /*your not-JSON-string*/;

function fix_botched_json($data) {
    //remove comment-section, we don't need it
    $data = substr($data, 10, strlen($data)-12);
    $seek = '/(\w+)/';
    $exploded = explode('"', $data);
    //explode so we only replace *outside* of strings

    $outside = true;
    foreach($exploded as &$item) {
        if($outside) {
            //the regex matches only word characters.
            $item = preg_replace($seek, '""', $item);
        }
        //alternating between inside and outside of strings
        $outside = !$outside;
    }
    //piece it back together
    $imploded = implode('"', $exploded);

    return $imploded;
}


$final = json_decode(fix_botched_json($data), true);

非常棘手的解决方案，不能保证与您可能拥有的其他字符串一起使用。有很多方法可以处理这种情况，最好的方法可能是要求警报系统的创建者开始生成有效的 JSON !

<?php

$string = '/*-secure- {    senrows : [ {no : "1", type : "Door Contact", zone : "1", name : "zone1", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "2", type : "Door Contact", zone : "2", name : "zone2", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "3", type : "Door Contact", zone : "3", name : "zone3", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "4", type : "Door Contact", zone : "4", name : "zone4", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "5", type : "Door Contact", zone : "5", name : "zone5", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "6", type : "Door Contact", zone : "6", name : "zone6", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "7", type : "Door Contact", zone : "7", name : "zone7", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "8", type : "Door Contact", zone : "8", name : "zone8", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "9", type : "Door Contact", zone : "9", name : "zone9", attr : "Burglar", cond : "", battery : "", tamp : "", bypass : "No"}, {no : "10", type : "IR Sensor", zone : "10", name : "zone10", attr : "Burglar", cond : "", battery : "Low", tamp : "", bypass : "No"}, {no : "11", type : "Remote Keypad", zone : "11", name : "zone11", attr : "",cond : "", battery : "", tamp : "", bypass : "No"}] } */';

function fix_json($st){
    $regex = '/([a-zA-Z0-9_]+)(\s)(?=:)/i';
    return preg_replace($regex, '""', $st);
}

$step1 = strstr($string, '{');
$step2 = rtrim($step1, '*/');


$data = fix_json($step2);

var_dump(json_decode($data, true));
