本文实例讲述了java调用中国天气网api获得天气预报信息的方法。分享给大家供大家参考。具体实现方法如下：

//以冰城哈尔滨为例通过中国天气api调用天气信息 private String getWeatherInfo2(){ StringBuilder info = new StringBuilder(); try { DefaultHttpClient httpclient = new DefaultHttpClient(); HttpGet httget = new HttpGet("http://m.weather.com.cn/data/101050101.html"); ResponseHandler<String> responseHandler = new BasicResponseHandler(); String responseBody = httpclient.execute(httget, responseHandler); System.out.println(responseBody); JsonParser jp = new JsonParser(); JsonElement jse = jp.parse(responseBody); JsonObject jso = jse.getAsJsonObject().get("weatherinfo").getAsJsonObject(); // String updTime = jso.get("fchh").getAsString(); // if(updTime != null){ // //温度 // String j = jso.get("temp1").getAsString();//今天 // String m = jso.get("temp2").getAsString();//明天 // //天气情况 // String j_weather = jso.get("weather1").getAsString();//今天 // String m_weather = jso.get("weather2").getAsString();//明天 // //风向风力 // String j_wind = jso.get("wind1").getAsString();//今天 // String m_wind = jso.get("wind2").getAsString();//明天 // info.append("今天：").append(j).append(" ").append(j_weather).append(" ").append(j_wind).append("n"); // info.append("明天：").append(m).append(" ").append(m_weather).append(" ").append(m_wind).append("n"); // } String updTime = jso.get("fchh").getAsString(); if(updTime != null){ if(!updTime.trim().equals("18")){ //温度 String j = jso.get("temp1").getAsString();//今天 String m = jso.get("temp2").getAsString();//明天 //天气情况 String j_weather = jso.get("weather1").getAsString();//今天 String m_weather = jso.get("weather2").getAsString();//明天 //风向风力 String j_wind = jso.get("wind1").getAsString();//今天 String m_wind = jso.get("wind2").getAsString();//明天 info.append("今天：").append(j).append(" ").append(j_weather).append(" ").append(j_wind).append("n"); info.append("明天：").append(m).append(" ").append(m_weather).append(" ").append(m_wind).append("n"); }else{ //18 //温度 String temp1 = jso.get("temp1").getAsString();//今天 String temp2 = jso.get("temp2").getAsString();//今天 String temp3 = jso.get("temp3").getAsString();//今天 String j = temp1.split("~")[1] + "~" + temp2.split("~")[0]; String m = temp2.split("~")[1] + "~" + temp3.split("~")[0];//明天 //天气情况 String weather1 = jso.get("weather1").getAsString(); String weather2 = jso.get("weather2").getAsString(); String weather3 = jso.get("weather3").getAsString(); String j_weather = ""; String j_weather_part1 = ""; String j_weather_part2 = ""; //判断是否有转 if(weather1.indexOf("转") > 0){ //有 j_weather_part1 = weather1.split("转")[1]; }else{ j_weather_part1 = weather1; } if(weather2.indexOf("转") > 0){ //有 j_weather_part2 = weather2.split("转")[0]; }else{ j_weather_part2 = weather2; } if(j_weather_part1.equalsIgnoreCase(j_weather_part2)){ j_weather = j_weather_part1;//今天 }else{ j_weather = j_weather_part1 + "转" + j_weather_part2;//今天 } String m_weather = ""; String m_weather_part1 = ""; String m_weather_part2 = ""; //判断是否有转 if(weather2.indexOf("转") > 0){ //有 m_weather_part1 = weather2.split("转")[1]; }else{ m_weather_part1 = weather2; } if(weather3.indexOf("转") > 0){ //有 m_weather_part2 = weather3.split("转")[0]; }else{ m_weather_part2 = weather3; } if(m_weather_part1.equalsIgnoreCase(m_weather_part2)){ m_weather = m_weather_part1;//今天 }else{ m_weather = m_weather_part1 + "转" + m_weather_part2;//明天 } //风向风力 String j_wind = jso.get("wind2").getAsString();//今天 String m_wind = jso.get("wind3").getAsString();//明天 info.append("今天：").append(j).append(" ").append(j_weather).append(" ").append(j_wind).append("n"); info.append("明天：").append(m).append(" ").append(m_weather).append(" ").append(m_wind).append("n"); } } } catch (Exception e) { } return info.toString(); }

希望本文所述对大家的java程序设计有所帮助。
