大家好 我刚才在写java天气预报 我用json解析的数据怎样放到java界面？

可以在JFrame中添加几个Label控件或其他文本控件用来展示解析出来的结果

创新互联坚持“要么做到，要么别承诺”的工作理念，服务领域包括：成都网站建设、成都做网站、企业官网、英文网站、手机端网站、网站推广等服务，满足客户于互联网时代的安远网站设计、移动媒体设计的需求，帮助企业找到有效的互联网解决方案。努力成为您成熟可靠的网络建设合作伙伴！

java调天气预报

①取出地址中的返回值（getWeatherReader方法）

②解析json格式的字符串

③形成你要展示的天气预报效果

public static String getWeatherReader() {//取得接口字符串

String currentLine = "";

String strReturn = "";

URL url = null;

HttpURLConnection conn = null;

InputStream in = null;

BufferedReader buff = null;

try {

url = new URL("");

System.out.println(url.toURI());

//打开地址链接

conn = (HttpURLConnection)url.openConnection();

conn.connect();

//接收数据

in = conn.getInputStream();

//如有乱码注意编码方式，如：UTF-8

buff = new BufferedReader(new InputStreamReader(in, "gb2312"));

while((currentLine = buff.readLine()) != null) {

strReturn += currentLine;

}

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

in.close();

buff.close();

} catch (IOException e) {

return "8EF0000";

}

}

return strReturn;

}

java调用天气预报api怎么写

//通过中国天气api调用

private String getWeatherInfo2(){

StringBuilder info = new StringBuilder();

try {

DefaultHttpClient httpclient = new DefaultHttpClient();

HttpGet httget = new HttpGet("");

ResponseHandlerString 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

}else{

j_weather_part2 = weather2;

}

if(j_weather_part1.equalsIgnoreCase(j_weather_part2)){

j_weather = j_weather_part1;//今天

}else{

return info.toString();

java web service实现天气预报功能

前台js界面代码：

//省份

function LoadProvince() {

$.ajax({

type: "POST",

url: "ashx/weatherHandler.ashx",

data: "option=province",

success: function (result) {

$(".sel-province option").remove();

var arry = result.split('|');

var obj = null;

for (var i = 0; i  arry.length; i++) {

if (arry[i] != null  arry[i] != "") {

obj = arry[i].split(',');

$(".sel-province").append("option value='" + obj[1] + "'" + obj[0] + "/option");

}

}

$(".sel-province").find("option[text='北京']").attr("selected", "selected");

},

error: function (errorMsg) {

$(".result-table tr").remove();

$(".result-table").append("trtd省份请求出现错误，请您稍后重试。。。/td/tr");

}

});

}

//城市

function LoadCity(provinceid) {   

$.ajax({

type: "POST",

}

},

error: function (errorMsg) {

$(".result-table tr").remove();

$(".result-table").append("trtd城市请求出现错误，请您稍后重试。。。/td/tr");

}

});

}

//加载天气

function GetWeather(cityid) {

$.ajax({

type: "POST",

url: "ashx/weatherHandler.ashx",

}

},

error: function (errorMsg) {

$(".result-table tr").remove();

$(".result-table").append("trtd天气数据请求出现错误，请您稍后重试。。。/td/tr");

}

});

}

html代码：

body

form id="form1" runat="server"

div class="head-div"

table

tr

td

select class="sel-province sel"

/select

/td

td

select class="sel-city sel"

/select

/td

td

input type="button" class="btn-search" value="查询" /

/td

/tr

/table

/div

div class="result-div"

table class="result-table"

/table

/div

/form

/body

由于js不支持跨域，直接ajax+ashx一般处理程序（在里面调用天气接口）。一般处理程序代码如下：

using System.Web;

using System.Text;

namespace WeatherTest.ashx

string option = context.Request.Form["option"];

switch (option)

{

case "province":

result = GetProvinces();

break;

case "city":

result = GetCitys(context.Request.Form["provinceid"]);

break;

case "weather":

result = GetWeather(context.Request.Form["cityid"], null);

break;

}

string str = ConvertToString(result, option);

context.Response.Write(str);

}

/// summary

private string ConvertToString(string[] result, string option)

{

foreach (string item in result)

{

sb.Append(item+"|");

}

return sb.ToString();

}

/// summary
