百度html的json解析,百度调用API返回json数据解析

在这里支队返回数据解析，不做请求数据

第一种格式json解析

String jsonresult

=”{"showapi_res_code":0,"showapi_res_error":"","showapi_res_body":{"list":[{"ct":"2016-02-01

04:10:14.665","p0":"5.02","p90":"5.08","p93":"5.38","p97":"5.68","prov":"河南"}],"ret_code":0}}“；

数据解析需要第三方 json-lib-2.2.3-jdk15.jar(这是我用的版本)

JSONObject json = JSONObject.fromObject(jsonResult);

int i = json.getInt("showapi_res_code"); //获取返回数据中的json数据

if(json.getInt("showapi_res_code")!=0){

System.out.println(json);

}

//获取返回数据中的json数据

JSONObject result =

(JSONObject) json.get("showapi_res_body");

System.out.println(result+"============");

//获取数组list

JSONArray list =

result.getJSONArray("list");

System.out.println(list+"-------------------");

//list中获取第一个元素，即json

JSONObject lists =

list.getJSONObject(0);

System.out.println(lists+"++++++++++++++");

String ct =(String)

list.getJSONObject(0).get("ct");

System.out.println(ct+"--------------------");

System.out.println(jsonResult);

解析结果

第二种格式json解析

String jsonresult=“{"HeWeather data service

JSONObject json = JSONObject.fromObject(jsonResult);

JSONArray array =

json.getJSONArray("HeWeather data service

3.0");//获取到内一层数组 System.out.println(array);

JSONObject basic = (JSONObject)

array.get(0);//获取数组中第一个元素json System.out.println(basic);

JSONObject basicjson =

basic.getJSONObject("basic");//获取数组中第一个元素json的对应的json System.out.println(basicjson);

JSONObject update =

basicjson.getJSONObject("update");//basicjson中所包含的json System.out.println(update);

String city =

basicjson.getString("city");//根据key获取对应的值 System.out.println(city);
