[C#] 图文解说调用WebServer实例

时间：2021-08-01 17:43:05

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

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：

                        document.getElementById("TDATWeather").innerHTML = obj.TDATWeather;

                        document.getElementById("TDATWindDirection").innerHTML = obj.TDATWindDirection;

                        //城市简介

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;

        }

    }

}
