VB 地大 web service 论文.doc

eb Services即Web服务。所谓服务就是系统提供一组接口，并通过接口使用系统提供的功能。同在Windows系统中应用程序通过API接口函数使用系统提供的服务一样，在Web站点之间，如果想要使用其他站点的资源，就需要其他站点提供服务，这个服务就是Web服务。和WebService同类的微软通信技术有wcf， .net remoting，命名管道等，虽然微软早就在2004年就不在维护此项技术，并且在同年推出WCF这个集大成者。但是 WebService毕竟还是有其优势之处。方便，简洁，跨平台，等都是其优点。但是缺点也有很多，比如安全性，无连接。通俗些说webservice就是个对外的接口，里面有函数方法可供外部客户调用（注意：里面同样有客户不可调用的函数）。假若我们是服务端，我们写好了个webservice，然后把它给了客户（同时我们给了他们调用规则），客户就可以在从服务端获取信息时处于一个相对透明的状态。即使客户不了解（也不需要）其过程，他们只获取数据。 webservice传递的数据只能是序列化的数据，典型的就是xml数据。在RFIDWebService 项目的web服务中，简单谈一下 webservice.看下目录结构，可以知道对外接口的文件时 service.asmx文件 ，我们打开：里面只有这句，当iis服务器解析它的时候回去 到service.cs 文件里去。我们在打开 我们发现public class Service : System.Web.Services.WebServicepublic Service () /如果使用设计的组件，请取消注释以下行/InitializeComponent();/ / 导购员登录/ / / / WebMethodpublic bool SalesLog ( string employeeName, string employeePassword )LogDAL logDAL = DALHelper.
