將無效的json轉換為有效的json

[英]Convert invalid json into valid json

我試圖從Web服務器讀取.json文件。 據我所知,我從服務器收到的JSON在http://jsonlint.com/上無效:

它顯示以下測試結果:

Parse error on line 1:
{    preOpen: "900",    
-----^
Expecting 'STRING', '}'

如何在使用PHP解析之前將其轉換為VALID JSON?

所有 (preOpen,preClose,...)必須是字符串,因此它們需要雙引號。

{
    "preOpen": "900",
    "preClose": "908",
    ...
}

===更新===

如果您有一個無效的Json-String,您可以使用以下腳本轉換它:

$sInvalidJson = '{
    preOpen: "900",
    preClose: "908"
}';
$sValidJson = preg_replace("/(\n[\t ]*)([^\t ]+):/", "$1\"$2\":", $sInvalidJson);

另請參見此示例

(此腳本僅適用於上述無效JSON,否則必須更改模式。)

===更新===

$sValidJson = preg_replace("/([{,])([a-zA-Z][^: ]+):/", "$1\"$2\":", $sInvalidJson);

這個更新的例子也是

提供的大多數解決方案都存在許多問題,主要是冒號。

我寫了一個json到數組函數,克服了這個問題。

它還檢查json字符串周圍的圓括號,並在json_decode之前將其刪除。

這是功能:

function jsonDecode($string, $assoc=true, $fixNames=true){
  if(strpos($string, '(') === 0){
    $string = substr($string, 1, strlen($string) - 2); // remove outer ( and )
  }
  if($fixNames){
    $string = preg_replace("/(?<!\"|'|\w)([a-zA-Z0-9_]+?)(?!\"|'|\w)\s?:/", "\"$1\":", $string);
  }
  return json_decode($string, $assoc);
}

它還檢查冒號前的空格,並從變量名中排除它們。

這是我測試的示例字符串:

({style:“border:5px solid pink;”,class:“test”,“correct”:“value”,test:true,var5:“some escapeped”string“})

轉換后:

Array
(
    [style] => border: 5px solid pink;
    [class] => test
    [correct] => value
    [test] => 1
    [var5] => some escaped" string
)

到目前為止,它看起來像防彈。

如果你找到一個洞,請告訴我。

我相信正確的JSON字符串也需要圍繞所有鍵名稱雙引號。 你展示的是一個有效的JavaScript對象,但是當字符串化為JSON時,所有鍵都應該有雙引號。

是的,這是錯誤的 - 關鍵名稱缺少引號。 您需要自己將其解析為字符串...或更改服務器上的文件。

需要引用屬性名稱。 有關示例,請參見http://json.org/example.html 我會更改服務器以生成適當的JSON。

它應該產生像{ "preOPen": "900", .... }
