//一：JSONObject转JSONArray
//json字符串转JSONObject
JSONObject json = (str); //json = {"settings":{"strategy":{"default":3,"ios":4},"ttl":36000000},"audience":["aaa","bbb"],"request_id":"1111111111112"}
//方法一： 调用JSONArray的add方法，将JSONObject对象添加到JSONArray中
JSONArray jsonArray = new JSONArray();
(json);
("方法一："+jsonArray); //jsonArray = [{"settings":{"strategy":{"default":3,"ios":4},"ttl":36000000},"audience":["aaa","bbb"],"request_id":"1111111111112"}]
//方法二：直接在json前后加上 [] 符号
String jsonArr = "["+json+"]";
("方法二："+jsonArr); // jsonArr = [{"settings":{"strategy":{"default":3,"ios":4},"ttl":36000000},"audience":["aaa","bbb"],"request_id":"1111111111112"}]
