本文旨在实现如何在.NET环境下调用WebServer，以天气接口为例进行说明。
WebServer地址：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx
1、创建程序。本例创建的是ASP.NET网站，可以根据个人需求创建不同的项目。
2、添加Web窗体。
3、页面设计采用BootStrap，在项目中引入相应的JS和CSS文件
4、在程序中添加WebServer服务。
①项目中右键，选择添加，找到服务引用，单击进入。如下图
②进入到如下界面，选择高级。
③选择左下角的添加Web引用。
④如图操作
5、添加实体类Weather.cs
using System;
/// <summary>
/// Summary description for weather
/// </summary>
namespace Model
{
public class Weather
{
public String Provinces { get; set; } //省份
public String CityName { get; set; } //城市
public String CityCode { get; set; } //城市代码
public String CityPicture { get; set; } //城市图片
public String UpdateTime { get; set; } //天气预报的更新时间
public String TodayWeather { get; set; } //当天温度
public String TodaySurvey { get; set; }
public String TodayWindDirection { get; set; }
public String TodayStarPic { get; set; }
public String TodayEndPic { get; set; }
public String Detail { get; set; } //天气实况
public String LifeIndex { get; set; } //生活指数
public String TomorrowWeather { get; set; } //第二天的气温
public String TomorrowSurvey { get; set; }//第二天的概况
public String TomorrowWindDirection { get; set; }//第二天的风向和风力
public String TomorrowStarPic { get; set; }//第二天的图标一
public String TomorrowEndPic { get; set; }//第二天的图标二
public String TDATWeather { get; set; }//第三天的气温
public String TDATSurvey { get; set; }//第三天的概况
public String TDATWindDirection { get; set; }//第三天的风向和风力
public String TDATStarPic { get; set; }//第三天的图标一
public String TDATEndPic { get; set; } //第三天的图标二
public String CityDetail { get; set; } //被查询的城市或地区的介绍 }
}
6、页面代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta name="viewport" content="width=device-width, minimum-scale=1.0, maximum-scale=1.0,user-scalable=no" />
<link rel="stylesheet" href="/public/bootstrap/3.3.4/css/bootstrap.min.css" />
<link rel="stylesheet" href="/public/bootstrap/3.3.4/css/bootstrap-theme.min.css" />
<script src="public/jquery/jquery.min.js"></script>
<script src="public/bootstrap/3.3.4/js/bootstrap.min.js"></script>
<title>天气预报</title>
<script>
$(document).ready(function () {
$("#BtnSearch").click(function () {
var cityName = document.getElementById("TxtCityName").value;
if (cityName == "" || cityName == null) {
alert("请输入要查询的城市名称！");
return false;
}
$.ajax({
type: "GET",
async: false,
url: "Ajax/GetWeatherInfo.ashx?CityName=" + cityName,
success: function (data) {
var obj = JSON.parse(data);
if (obj.CityName == "" || obj.CityName == null) {
alert("查询结果为空！这城市或区域暂时不支持查询，请检查输入城市是否有误！");
return false;
}
document.getElementById("todayWeatherDetail").style.display = "block";
document.getElementById("tomorrowWeatherDetail").style.display = "block";
document.getElementById("tdatWeatherDetail").style.display = "block";
document.getElementById("cityDetail").style.display = "block"; //当天
document.getElementById("todaySurvey").innerHTML = obj.TodaySurvey;
document.getElementById("todayWeather").innerHTML = obj.TodayWeather;
document.getElementById("todayWindDirection").innerHTML = obj.TodayWindDirection;
document.getElementById("detail").innerHTML = obj.Detail;
document.getElementById("lifeIndex").innerHTML = obj.LifeIndex;
//第二天
document.getElementById("tomorrowSurvey").innerHTML = obj.TomorrowSurvey;
document.getElementById("tomorrowWeather").innerHTML = obj.TomorrowWeather;
document.getElementById("tomorrowWindDirection").innerHTML = obj.TomorrowWindDirection;
//第三天
document.getElementById("taftSurvey").innerHTML = obj.TDATSurvey;
document.getElementById("TDATWeather").innerHTML = obj.TDATWeather;
document.getElementById("TDATWindDirection").innerHTML = obj.TDATWindDirection;
//城市简介
document.getElementById("cityName").innerHTML = obj.CityName + "简介";
document.getElementById("CityDetail").innerHTML = obj.CityDetail;
}
});
});
});
</script>
</head>
<body>
<div class="container">
<div style="margin-top: 10px;" class="container">
<div class="form-group" style="width: 70%; float: left; margin-right: 20px;">
<input class="form-control" id="TxtCityName" placeholder="请输入城市名称" />
</div>
<button id="BtnSearch" class="btn btn-primary">查询</button>
</div>
<div class="container">
<div class="panel panel-success" style="display: none;margin-top:3px;" id="todayWeatherDetail">
<div class="panel-heading">
<a data-toggle="collapse" data-parent="#accordion" href="#todayWeathercollapse" aria-expanded="true" aria-controls="collapse">
<label id="todaySurvey"></label>
</a>
</div>
<div id="todayWeathercollapse" class="panel-collapse collapse in">
<div class="panel-body">
<p><label id="todayWeather"></label></p>
<p><label id="todayWindDirection"></label></p>
<p><label id="detail"></label></p>
<p><label id="lifeIndex"></label></p>
</div>
</div>
</div> <div class="panel panel-warning" style="display: none;" id="tomorrowWeatherDetail">
<div class="panel-heading">

<div class="panel-body">
<p><label id="tomorrowWeather"></label></p>

</div>
</div>
</div> <div class="panel panel-danger" style="display: none;" id="tdatWeatherDetail">
<div class="panel-heading">
<a data-toggle="collapse" data-parent="#accordion" href="#tdatWeathercollapse" aria-expanded="true" aria-controls="collapse">

</a>
</div>
<div id="tdatWeathercollapse" class="panel-collapse collapse">
<div class="panel-body">
<p><label id="TDATWeather"></label></p>
<p><label id="TDATWindDirection"></label></p>
</div>
</div>
</div> <div class="panel panel-info" style="display: none;" id="cityDetail">
<div class="panel-heading">
<a data-toggle="collapse" data-parent="#accordion" href="#cityDetailcollapse" aria-expanded="true" aria-controls="collapse">
<label id="cityName"></label>
</a>
</div>
<div id="cityDetailcollapse" class="panel-collapse collapse">
<div class="panel-body">
<label id="CityDetail">
</label>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
7、一般处理程序的代码如下：调用WebServer的代码在此体现，详细请看代码注释。
<%@ WebHandler Language="C#" Class="GetWeatherInfo" %> using System;
using System.Web; public class GetWeatherInfo : IHttpHandler
{ public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string cityName = context.Request.Params["CityName"]; Model.Weather weather = new Model.Weather(); Weather.WeatherWebService w = new Weather.WeatherWebService(); //调用WebServer，其中Weather是引入WebServer服务是取的引用名
string[] res = new string[];
res = w.getWeatherbyCityName(cityName); //调用getWeatherbyCityName方法 weather.Provinces = res[]; //省份
weather.CityName = res[]; //城市
weather.CityCode = res[]; //城市代码
weather.CityPicture = res[]; //城市图片
weather.UpdateTime = res[]; //天气预报的更新时间
weather.TodayWeather = res[]; //当天温度
weather.TodaySurvey = res[];
weather.TodayWindDirection = res[];
weather.TodayStarPic = res[];
weather.TodayEndPic = res[];
weather.Detail = res[]; //天气实况
weather.LifeIndex = res[]; //生活指数
weather.TomorrowWeather = res[]; //第二天的气温
weather.TomorrowSurvey = res[]; //第二天的概况
weather.TomorrowWindDirection = res[]; //第二天的风向和风力
weather.TomorrowStarPic = res[]; //第二天的图标一
weather.TomorrowEndPic = res[]; //第二天的图标二
weather.TDATWeather = res[]; //第三天的气温
weather.TDATSurvey = res[]; //第三天的概况
weather.TDATWindDirection = res[]; //第三天的风向和风力
weather.TDATStarPic = res[]; //第三天的图标一
weather.TDATEndPic = res[]; //第三天的图标二
weather.CityDetail = res[]; //被查询的城市或地区的介绍 System.Text.StringBuilder stringBuilder = new System.Text.StringBuilder();
System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer(); jss.Serialize(weather, stringBuilder); context.Response.Write(stringBuilder);
} public bool IsReusable
{
get
{
return false;
}
} }
8、运行效果如下：
