自己开发一个天气预报服务
作者：贺星河(hxhbluestar) 时间：2005-1-16 [文章导读] 本文介绍了在基于Smartphone操作系统的智能手机上开发一个天气预报服务的程序。 我们都知道QQ有一个免费提供给Blog引用的天气预报服务网址http://appnews.qq.com/cgi-bin/news_qq_search?city=上海（上海是我自己所在城市，如果想看自己的城市，在浏览器中改成城市名称即可），现在我使用QQ提供的这个服务，将其包装部署为一个Web服务，并编写程序使得我的多普达565智能手机能使用这个Web服务。 [正文] PC开发环境：Windows XP SP2，Visual Studio 2003.NET,.NET Framework 1.1 SP1 操作系统：Windows Mobile(TM) 2003第二版，版本4.21.1088(Build 14235.2.0.0) 智能手机型号：多普达565 一、安装必备的环境 注意：必须安装.NET Mobile所需要的开发环境
2、Microsoft SMARTPHONE 2003 SDK.msi 1、建立一个名为WeatherService的WebService，并将QQ的天气服务转为XML WebService服务，部署在一台具有固定IP的服务器上。 2、新建一个WeatherDataSet.XSD，存储我们的天气信息 ?<?xml version="1.0" encoding="utf-8" ?> <xs:schema id="WeatherDataSet" targetNamespace="Ezhi.Services.WeatherService" elementFormDefault="qualified" ???? attributeFormDefault="qualified" xmlns="Ezhi.Services.WeatherService" xmlns:mstns="Ezhi.Services.WeatherService" ???? xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata"> ???? <xs:element name="WeatherDataSet" msdata:IsDataSet="true"> ???????? <xs:complexType> ????????????? <xs:choice maxOccurs="unbounded"> ?????????????????? <xs:element name="WeatherDS"> ?????????????????????? <xs:complexType> ??????????????????????????? <xs:sequence> ???????????????????????????????? <xs:element name="CityName" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="Date1" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="Weather1" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="Temp1" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="WindPower1" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="Date2" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="Weather2" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="Temp2" type="xs:string" minOccurs="0" /> ???????????????????????????????? <xs:element name="WindPower2" type="xs:string" minOccurs="0" /> ??????????????????????????? </xs:sequence> ?????????????????????? </xs:complexType> ?????????????????? </xs:element> ????????????? </xs:choice> ???????? </xs:complexType> ???? </xs:element> </xs:schema> 3 WeatherService的源代码如下 using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.Web; using System.Web.Services; using System.IO; using System.Net; using System.Text; #endregion namespace WeatherService { ???? /// <summary> ???? /// Service1 的摘要说明。 ???? /// </summary> ????

图4－部署解决方案 选择“部署”，“部署”完成后，手机上将显示如下界面
图5、手机界面之一－部署 因为我的PC机器上安装了.NET Framework1.1SP1，所以会提示这个界面，选择“确定”，继续执行安装部署：
图6、手机界面之二－选择安装位置 选择安装位置为”Sotrage Card”,选择“完成”,这个时候程序就部署完毕了， 使用Resco Explore 2003，找到安装部署后程序所在的目录，在 /Sorage/Program Files/WeatherService/ 目录下面，执行程序WeatherService.exe，将出现如下画面：
图7、手机界面之三－开始执行程序 选择“是”，之所以出现这个画面，是因为程序没有经过系统的认证，也是微软安全方面的一个体现，即时这个程序会正常执行，也不会冒然打出电话！ 程序执行之后，会出现如下画面，选择需要查询的城市名称，点“确定”
图8、手机界面之四－程序界面 之后程序标题会变为“正在下载…”，程序通过GPRS上网读取部署在Internet上的WebService
图9、手机界面之五－运行界面 稍等几秒钟之后，便会看到所需要的天气信息数据
图10、手机界面之六－运行结果 全文完 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
