Question

我使用快速Json解析Json字符串的格式检索所有歌曲的标题

我正在使用的API是歌曲API。我试图解析哈希映射，但我得到null。如果有人能告诉我如何解析hashmap以获得标题

        JsonParserFactory factory=JsonParserFactory.getInstance();
        JSONParser parser = factory.newJsonParser();
        Map jsonData=parser.parseJson(StringJson);
        String f = (String)jsonData.get("response");

Answer 1

下面给出了所有标题的列表:

  List f =  (List) (((Map) jsonData.get("response")).get("songs"));
   Iterator iter =   f.iterator();
  while(iter.hasNext()){
     System.out.println(((Map) iter.next()).get("title"));
  }
