我们用这个封装方法来解析Json数组
public static <T> List<T> getObjectList(String jsonString,Class<T> cls){ List<T> list = new ArrayList<T>(); try { Gson gson = new Gson(); JsonArray arry = new JsonParser().parse(jsonString).getAsJsonArray(); for (JsonElement jsonElement : arry) { list.add(gson.fromJson(jsonElement, cls)); } } catch (Exception e) { e.printStackTrace(); } return list; }
用这个方法来对URL进行解析和设置
public static String getUrlForHero(String strURL) throws IOException { URL url = new URL(strURL); HttpURLConnection httpConn = (HttpURLConnection) url.openConnection(); httpConn.setRequestMethod("GET"); httpConn.connect(); BufferedReader reader = new BufferedReader(new InputStreamReader( httpConn.getInputStream())); String line; StringBuffer buffer = new StringBuffer(); while ((line = reader.readLine()) != null) { buffer.append(line); } reader.close(); httpConn.disconnect(); String result = new String(buffer.substring(20,buffer.length()-27));//这里把不用的数据去掉,保留heroes之后的数组，status,count不要。 //JSONArray jsonArray = JSONArray.fromObject(result); return result; }
最后这样调用
private void addHeroFromSteamAPI() throws IOException { String jsonArray = URLUtil.getUrlForHero("https://api.steampowered.com/IEconDOTA2_570/GetHeroes/v1/?key=id&format=json&language=Chinese"); List<Hero> heroes = GsonUtil.getObjectList(jsonArray,Hero.class); for (Hero hero:heroes){ HeroBean heroBean = new HeroBean(); heroBean.setId(hero.getId()); heroBean.setName(hero.getName()); heroBean.setLocalizedName(hero.getLocalized_name()); heroService.addHeroFromSteamAPI(heroBean); } }
