百度API服务和风天气获取当前天气信息，有需要的朋友可以参考下。工具类：package com.weather.import java.io.BufferedRimport java.io.InputSimport java.io.InputStreamRimport java.net.HttpURLCimport java.net.URL;public class WeatherUtil {/*** @param urlAll*
:请求接口* @param httpArg*
:参数* @return 返回结果*/public String request(String httpUrl, String httpArg) {BufferedReader reader =String result =StringBuffer sbf = new StringBuffer();httpUrl = httpUrl + &?& + httpAtry {URL url = new URL(httpUrl);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setRequestMethod(&GET&);// 填入apikey到HTTP headerconnection.setRequestProperty(&apikey&,&&);connection.connect();InputStream is = connection.getInputStream();reader = new BufferedReader(new InputStreamReader(is, &UTF-8&));String strRead =while ((strRead = reader.readLine()) != null) {sbf.append(strRead);sbf.append(&/r/n&);}reader.close();result = sbf.toString();} catch (Exception e) {e.printStackTrace();}}}调用方：public static String httpUrl = &/heweather/weather/free&;public static String httpArg = &city=guilin&;String jsonResult = weatherUtil.request(httpUrl, httpArg);javascript&jquery:function weather(){
var weather =${jsonResult};/*EL表达式接收jsonResult*/
var weat = JSON.stringify(weather);
weat = weat.replace(&HeWeather data service 3.0&,&weather&);/*修改名称为：weather方便调用*/
var weJson = JSON.parse(weat);
var nowWeather = weJson.weather[0].basic.city+
& &+weJson.weather[0].now.cond.txt+
& &+weJson.weather[0].now.tmp+&°&+
& &+weJson.weather[0].now.wind.dir+weJson.weather[0].now.wind.
$(&#nowWeather&).html(nowWeather);/*nowWeather显示：城市
天气状况描述
alert(nowWeather);
weather();参考:/apiworks/servicedetail/478.html和风天气文档:/documents/condition-code
