本文實例講述了java調用中國天氣網api獲得天氣預報信息的方法。分享給大家供大家參考。具體實現方法如下：
//以冰城哈爾濱為例通過中國天氣api調用天氣信息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){// //溫度// String j = jso.get("temp1").getAsString();//今天// String m = jso.get(" temp2").getAsString();//明天// //天氣情況// String j_weather = jso.get("weather1").getAsString();//今天// String m_weather = jso.get("weather2" ).getAsString();//明天// //風向風力// 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")){ //溫度String j = jso.get("temp1").getAsString();//今天String m = jso.get("temp2").getAsString();//明天//天氣情況String j_weather = jso.get("weather1" ).getAsString();//今天String m_weather = jso.get("weather2").getAsString();//明天//風向風力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 //溫度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//天氣情況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 = ""; //判斷是否有轉if(weather1.indexOf("轉") > 0){ //有j_weather_part1 = weather1.split("轉")[1]; }else { j_weather_part1 = weather1; } if(weather2.indexOf("轉") > 0){ //有j_weather_part2 = weather2.split("轉")[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 + "轉" + j_weather_part2;//今天} String m_weather = ""; String m_weather_part1 = ""; String m_weather_part2 = ""; //判斷是否有轉if(weather2.indexOf("轉") > 0){ //有m_weather_part1 = weather2.split("轉")[1]; }else{ m_weather_part1 = weather2; } if(weather3.indexOf("轉") > 0){ //有m_weather_part2 = weather3.split("轉")[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 + "轉" + m_weather_part2;//明天} //風向風力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();}希望本文所述對大家的java程序設計有所幫助。
