JSONObject traversing get key

JSONObject traversing get the key:

JSONObject hostObject = new JSONObject(str);
Iterator<String> sIterator = hostObject.keys();
while(sIterator.hasNext()){
	// 获得key
	String key = sIterator.next();
	// 根据key获得value, value也可以是JSONObject,JSONArray,使用对应的参数接收即可
	String value = hostObject.getString(key);
	System.out.println("key: "+key+",value"+value);
}
