获取天气预报及天气预警接口数据

对于接口不熟悉，源自于一次项目需要，体会到学习的重要性，好好学习，天天向上！

//1.发送请求

String url="http://...";
String resultString = HttpClientUtil.doPost(url);
//2. 解析返回值
ResultEntity resultEntity = jm.fromJson(resultString, ResultEntity.class);
//3.获取数据
Map data = (Map)resultEntity.getData();
Map todayWeather = (Map)data.get("todayWeather");
model.addAttribute("todayWeather", todayWeather);

前端获取数据：

<div class="weather">天气：
<c:choose>
<c:when test="${todayWeather.tempdescday == todayWeather.tempdescnight}">
${todayWeather.tempdescday}
</c:when>
<c:otherwise>
${todayWeather.tempdescday }转${todayWeather.tempdescnight}
</c:otherwise>
</c:choose>
&nbsp&nbsp&nbsp${todayWeather.temphigh}℃~${todayWeather.templow}℃</div>
</div>
