甚至在解碼後，node.js中的JSON解析錯誤URL

Question

data={"convID":"E40E92FD4B410","serverDate":"2012/06/15 07:51:07 PM","masterInfo":{"instance":"808477149_R_BDD72269D1C1E98A32D8C83EC58CF471","appVersion":"0.97.13.D","depth":4,"jsonURL":"//testtn","scenario":"R","serverDate":"2012/06/15 07:51:07 PM ","deviceName":"M’s","localDate":"2012/5/6 11:14:59 AM PDT"}} 

JSON.parse(data); 

給出錯誤。這是由ruby腳本中的JSON.generate生成的，併發送給節點http服務器，應用decodeURIComponent獲取上面打印的數據。還是JSON解析失敗，此錯誤：

undefined:1 
ate":"2012/06/15 
^ 
SyntaxError: Unexpected token d 
at Object.parse (native) 

Answer 1

在你的代碼示例data是JS對象。但是JSON.parse以字符串作爲參數，而不是對象。所以，你的代碼必須是：

data='{"convID":"E40E92FD4B410","serverDate":"2012/06/15 07:51:07 PM","masterInfo":{"instance":"808477149_R_BDD72269D1C1E98A32D8C83EC58CF471","appVersion":"0.97.13.D","depth":4,"jsonURL":"//testtn","scenario":"R","serverDate":"2012/06/15 07:51:07 PM ","deviceName":"M’s","localDate":"2012/5/6 11:14:59 AM PDT"}}'; 

JSON.parse(data); 

所以，檢查值和data變量您的真實代碼的類型。
