Java escape JSON String?

Question

I have the following JSON string that i am sending to a NodeJS server:

String string = \"{\\\"id\\\":\\\"\" + userID + \"\\\",\\\"type\\\":\\\"\" + methoden

I would use a library to create your JSON String for you. Some options are:

• GSON
• Crockford's lib

This will make dealing with escaping much easier. An example (using org.json) would be:

JSONObject obj = new JSONObject();

obj.put("id", userID);
obj.put("type", methoden);
obj.put("msg", msget);

// etc.

final String json = obj.toString(); // <-- JSON string
