Java Convert this string to JSONArray [closed]

问题:

I am getting the following String response from a server:

{"fid":"1272","uri":"http://someurl/services/file/1272"} 

I need to convert it into a JSONArray. Any help?

By the way, I tried this and it does not work:

String response=getResponseFromServer(); JSONArray array = new JSONArray(response); 

I get the error:

org.json.JSONException: Value {"fid":"1272","uri":"http://someurl/services/file/1272"} of type org.json.JSONObject cannot be converted to JSONArray

If you're talking about using the JSON in java library, then since your input string is a JSON object, not a JSON array, you should first load it using JSONObject:

String response=getResponseFromServer(); JSONObject jsonObject = new JSONObject(response); 

After that, you can use toJSONArray() to convert a JSONObject to JSONArray given an array of key strings:

String[] names = JSONObject.getNames(jsonObject); JSONArray jsonArray = jsonObject.toJSONArray(new JSONArray(names));

If you do a search right here on StackOverflow for Java String to JSONArray, you should get this answer: Converting from JSONArray to String then back again

JSONArray jArray; String s = jArray.toString(); // basically what you have ;) JSONArray newJArray = new JSONArray(s);
