JSON Escaping double quotes not working

Question

I'm getting errors on a screen when it's trying to eval some json, it's giving me the error unexpected identifier..

The data causing the issue and how it's coming back when I check the Json response is:

"itemDescription":"STANDARD \\"B\\" RED BOX",

I'm using the below code in the java to handle the double quotes:

itemDescription = itemDescription.replaceAll("\\r|\\n", "");
itemDescription = itemDescription.replaceAll("\"", "\\\\\"");
itemDescription = itemDescription.replaceAll("'", "'");

Any idea why this wouldn't be working? If I remove the double quotes, I no longer get any errors.

Item descriptions such as "itemDescription":"STANDARD 16\\" RED BOX" go through fine..

Thanks!

Answer 1

You need two more backslashes at line 2:

itemDescription = itemDescription.replaceAll("\"", "\\\\\\\"").

So that " is replaced by \\\\\\" and not \\\\" .

Answer 2

尝试使用StringEscapeUtils ：

itemDescription  = StringEscapeUtils.escapeJson(itemDescription);
