微信公众号开发引入外部接口查询天气预报

    // 配置申请的KEY

    public static final String APPKEY = "6d5b277db885b2df42672cb10c412345";

    // 1.根据城市查询天气

    public static String findWeather(String city) {

        String result = null;

        String url = "http://op.juhe.cn/onebox/weather/query";// 请求接口地址

        Map params = new HashMap();// 请求参数

        params.put("cityname",city );// 要查询的城市，如：温州、上海、北京

        params.put("key", APPKEY);// 应用APPKEY(应用详细页查询)

        params.put("dtype", "");// 返回数据的格式,xml或json，默认json

        String resp = "";

        try {

            result = MyUtil.net(url, params, "GET");

            JSONObject object = JSONObject.fromObject(result);

            if(!object.getString("reason").equals("查询成功!")){

                return resp = "请输入正确城市名";

            }

            JSONObject obj = object.getJSONObject("result")

                    .getJSONObject("data").getJSONObject("realtime");

            resp = "城市: " + obj.getString("city_name") + "\n" + "阳历: "

                    + obj.getString("moon") + "\n" + "气温:"

                    + obj.getJSONObject("weather").getString("temperature")+ "度\n天气状况:"

                    + obj.getJSONObject("weather").getString("info") + "\n"

                    + "风向: " + obj.getJSONObject("wind").getString("direct")
