String转换为json对

JSONObject jsonObject = new JSONObject();
jsonObject.put("json", upKbmsKnowledgeList);
String jsonString =jsonObject.getString("json");

String sTotalString = "{/"status/":0,/"info/":/"\u7b7e\u540d\u9519\u8bef/"}";

/**根据返回成功的信息，取出里面的字符串转换为json进行取值*/
JSONObject obj = JSONObject.fromObject(sTotalString);
/**状态**/
String status ="";
String info ="";
/*转换为json对象后，取出值**/
if(sTotalString.indexOf("status")>0){
status = obj.getString("status");

}
if(sTotalString.indexOf("info")>0){
info = obj.getString("info");

}
