我無法使用JSON.parse()函數解析以下字符串。 起初我試圖刪除最初和最後的雙引號。然後我刪除了轉義字符。如何用轉義字符解析字符串包含的json對象?

如何解析這種類型的JSON響應?

首先,它解析正確。 [樣品](https://jsfiddle.net/g98p5rt7/)。其次,如果您遇到錯誤,您可以與我們分享嗎? – Rajesh

我認爲你想要做的就是兩次傳球。看起來這是通過對主體進行字符串化創建的,將其添加到主對象並再次將整個事件串聯起來。試試:'JSON.parse(JSON.parse(theObj).body)' –

沒有工作。你可以給我看一個JSFiddle嗎? – Reza

假設它是一個真正的字符串(例如,從網絡請求或類似的),你就可以使用JSON.parse。然後,由於body屬性是一個包含JSON的字符串(例如,由於某種原因,其內容已被雙字符串化),因此您再次解析該字符串。

例子:

var json = '{\n' + 
 
' "timestamp": 1490545425158,\n' + 
 
' "reports": {\n' + 
 
' "statusCode": 200,\n' +

' }\n' + 
 
'}'; 
 
var parsed = JSON.parse(json); 
 
parsed.reports.body = JSON.parse(parsed.reports.body); // This is the second parse 
 
console.log(parsed);

:理想情況下,你要修復這是不必要的雙字符串化body源。

當然,如果有什麼地方已經完成了第一解析爲您(例如,許多庫會自動解析JSON通過AJAX檢索),那麼你當然不需要,首先解析:

您需要解析正文:

JSON.parse(object.reports.body)

剩下的已經是 「已解析」。
