我試圖從Web服務器讀取.json文件。我從服務器接收的JSON報道是無效的http://jsonlint.com/將無效的json轉換爲有效的json

它顯示了以下測試結果:

Expecting 'STRING', '}' 

我怎樣才能將其轉換爲VALID JSON解析之前使用PHP?

鍵必須用雙引號 - 所以preOpen:「900」必須是「preOpen」:「900」,依此類推。不確定如何解決它,如果你不能控制json源碼。您可以使用正則表達式 - 在冒號前查找單個單詞並將其包含在雙引號中。 – 2012-01-11 07:30:18

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

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

=== UPDATE ===

如果你有一個無效的JSON字符串你可以用下面的腳本轉換它:

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

也看到這個example

(該腳本僅具有上述無效JSON工作,否則模式已經被改變。)

我使用下面的代碼沒有成功:'$ url ='http://abc/abc.json'; $ session = curl_init($ url); ($; session,CURLOPT_USERAGENT,'Mozilla/5.0(Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13)Gecko/20080311 Firefox/2.0.0.13'); curl_setopt($ session,CURLOPT_POST,true); curl_setopt($ session,CURLOPT_HEADER,false); curl_setopt($ session,CURLOPT_RETURNTRANSFER,true); $ json = curl_exec($ session); echo $ json; echo「

我相信正確的JSON字符串也需要在所有鍵名稱周圍加雙引號。你所展示的是一個有效的JavaScript對象,但是當把字符串化成JSON時,應該在所有的鍵周圍加雙引號。

+0

是的,通過使用'JSON.stringify(eval({preOpen:「900」,....}))',返回有效的JSON。 @ Sandy505然而,使用eval是危險的,特別是如果數據來自第三方來源,因爲您不知道可以傳遞什麼。它也可能是惡意代碼注入您的網頁。無論如何,這不是PHP方面。 – 2012-01-11 07:36:01

屬性名稱需要引用。一個例子見http://json.org/example.html。我會更改服務器以生成適當的JSON。

應該產生類似 { "preOPen": "900", .... }

是啊,它的格式不正確 - 缺左右鍵名報價。你需要自己將其解析爲字符串...或者在服務器上更改文件。

大多數解決方案都存在一些問題,主要是冒號。

我寫了一個json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之前刪除它。

下面是函數:

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); 
} 

它還檢查空格冒號之前和變量名排除。

下面是我測試的示例串:

({風格: 「邊境:5px的固體粉紅色;」 類: 「測試」, 「正確」: 「值」, 測試:真實, VAR5: 「一些逃出\」 串「})

轉換後:

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

到目前爲止,它看起來防彈

如果你發現一個洞,讓我知道。
