org.json.JSONException: Unterminated string at 737 [character 738 line 1]

Question

I'm using the org.json.JSONObject to parse some json being sent to my servlet by an iphone. I was stuck for a while by why I would be getting an error message at all. The error message was:

org.json.JSONException: Unterminated string at 737 [character 738 line 1]

After printing out what I received, I see that the string sent was indeed cut short and stopped mid-json. I can't understand why it would be cut short. There's no limit on String size is there (or at least only a memory limit surely).

Has anyone else had thins error?

Cheers

Answer 1

json适用于\\ n但是如果你的meesage中有任何其他特殊字符，如\\，@，＆，＃etc ..首先将它们转换为各自的HEX值然后发送你的消息。

Answer 2

If you're using the HTTP GET method to send data using query parameters, realize that there's a practical limit on the amount of data you can send that way. It's about 2000 characters (varies by server and client). You can easily exceed that when URL encoding a shorter string.

Answer 3

Json won't work if received string contain new line character like \\n. Try to check for it and escape the character.
