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=" 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"> <a data-toggle="collapse" data-parent="#accordion" href="#tomorrowWeathercollapse" aria-expanded="true" aria-controls="collapse"> <label id="tomorrowSurvey"></label> </a> </div> <div id="tomorrowWeathercollapse" class="panel-collapse collapse"> <div class="panel-body"> <p><label id="tomorrowWeather"></label></p> <p><label id="tomorrowWindDirection"></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"> <label id="taftSurvey"></label> </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[23]; res = w.getWeatherbyCityName(cityName); //调用getWeatherbyCityName方法 weather.Provinces = res[0]; //省份 weather.CityName = res[1]; //城市 weather.CityCode = res[2]; //城市代码 weather.CityPicture = res[3]; //城市图片 weather.UpdateTime = res[4]; //天气预报的更新时间 weather.TodayWeather = res[5]; //当天温度 weather.TodaySurvey = res[6]; weather.TodayWindDirection = res[7]; weather.TodayStarPic = res[8]; weather.TodayEndPic = res[9]; weather.Detail = res[10]; //天气实况 weather.LifeIndex = res[11]; //生活指数 weather.TomorrowWeather = res[12]; //第二天的气温 weather.TomorrowSurvey = res[13]; //第二天的概况 weather.TomorrowWindDirection = res[14]; //第二天的风向和风力 weather.TomorrowStarPic = res[15]; //第二天的图标一 weather.TomorrowEndPic = res[16]; //第二天的图标二 weather.TDATWeather = res[17]; //第三天的气温 weather.TDATSurvey = res[18]; //第三天的概况 weather.TDATWindDirection = res[19]; //第三天的风向和风力 weather.TDATStarPic = res[20]; //第三天的图标一 weather.TDATEndPic = res[21]; //第三天的图标二 weather.CityDetail = res[22]; //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：
