Android爬取网页JSON数据详细教程【新手向】

这几天做一个Android获取JSON的任务，发现jsoup只能获取静态页面，无法获取动态页面的Json数据。

有同学给我更正：Jsoup可以爬取动态页面，但必须要加请求头(data)，以下为正确例子：

String url = "你的网页接口";
Map data = Maps.newHashMap();
data.put("countryCode", "+86");
data.put("mobile", mobile);
data.put("passWord", "f20332f07cdaab9ec0472655a83438d4");
data.put("invitionCode", "PU9HFMNMZ2FL");
data.put("validateCode", codeCallable);
data.put("geetest_challenge", challenge);
data.put("geetest_validate", validate);
data.put("geetest_seccode", validate + "|jordan");
String json = JSON.toJSONString(data);
Connection.Response response = Jsoup.connect(url).ignoreContentType(true).data(data).requestBody(json)
.header("Accept", "application/json, text/plain, *
                    String NewsData = stringBuffer.toString();
                    JSONObject jb = JSON.parseObject(NewsData);
                    String Newsdata2 = jb.getString("data");
                    JSONObject jb1 = JSON.parseObject(Newsdata2);
                    String Newsdata3 = jb1.getString("list");
                    Log.e("Newsdata3", "Newsdata3"+Newsdata3);
                    List DNews = JSON.parseArray(Newsdata3, News.class);
                    for (News TT:DNews)
                    {
                        jsonTeacherEntity = new News();
                        int id = TT.getId();
                        String game_name = TT.getGame_name();
                        int is_grandslm = TT.getIs_grandslm();
                        String game_level = TT.getGame_level();
                        String ground_name = TT.getGround_name();
                        String match_time = TT.getMatch_time();
                        jsonTeacherEntity.setId(id);
                        jsonTeacherEntity.setGame_name(game_name);
                        jsonTeacherEntity.setGame_level(game_level);
                        jsonTeacherEntity.setIs_grandslm(is_grandslm);
                        jsonTeacherEntity.setGround_name(ground_name);
                        jsonTeacherEntity.setMatch_time(match_time);
                        NewsList.add(jsonTeacherEntity);
                    }
                }
            } catch (MalfORMedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }
        @Override
        protected void onPostExecute(Object o) {
            super.onPostExecute(o);
            //通知适配器发生改变
            myAdapter.notifyDataSetChanged();
            //取消进度条对话框
            progressDialog.cancel();
        }
    }
}
