1、json数字
{ "age":30 }
2、json对象
{ "name":"快递6666" , "url":"www.kuidi6666.com" }
3、json数组
{ "sites": [ { "name":"学习java" , "url":"www.xuexi.com" }, { "name":"google" , "url":"www.xiaoyou.com" }, { "name":"微博" , "url":"www.weibo.com" } ] }
4、json解析
String s = "{\"error\":0,\"status\":\"success\",\"results\":[{\"currentCity\":\"青岛\",\"index\":[{\"title\":\"穿衣\",\"zs\":\"较冷\",\"tipt\":\"穿衣指数\",\"des\":\"建议着厚外套加毛衣等服装。年老体弱者宜着大衣、呢外套加羊毛衫。\"},{\"title\":\"紫外线强度\",\"zs\":\"最弱\",\"tipt\":\"紫外线强度指数\",\"des\":\"属弱紫外线辐射天气,无需特别防护。若长期在户外,建议涂擦SPF在8-12之间的防晒护肤品。。\"}],}]}";
JSONObject jsonObject = JSONObject.fromObject(s); //提取出error为 0
int error = jsonObject.getInt("error");
System.out.println("error:" + error);
//提取出status为 success
String status = jsonObject.getString("status");
System.out.println("status:" + status);
//注意:results中的内容带有中括号[],所以要转化为JSONArray类型的对象
JSONArray result = jsonObject.getJSONArray("results");
for (int i = 0; i < result.size(); i++) {
//提取出currentCity为 青岛
String currentCity = result.getJSONObject(i).getString("currentCity");
System.out.println("currentCity:" + currentCity);
//注意:index中的内容带有中括号[],所以要转化为JSONArray类型的对象
JSONArray index = result.getJSONObject(i).getJSONArray("index");
for (int j = 0; j < index.size(); j++) {
String title = index.getJSONObject(j).getString("title");
System.out.println("title:" + title);
}
}
通过以上步骤即可完成json多层嵌套的解析!!
