Web Service 使用

浏览数：8 / 时间：2015年06月09日

SOAP、WSDL、UDDI
SOAP(Simple Object Access Protocal)，是在分散或在分布式环境中交换信息的简单协议。
WSDL 对WebService 的解释说明文档
UDDI （通用发现、说明和集成）是Web服务的黄页
趣味理解：
Web Service 好比是一个服务供应商；
SOAP 就像是两个公司之间签的合同，约束双方按照一定的规范和标准做事；
WSDL就像说明书，告诉别人你有什么，能给别人提供什么服务；
UDDI好比你的公司需要在黄页或工商注册，方便别人查询

调用代码：

using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using  WebApplicationTestWebService.ServiceReference1;

namespace WebApplicationTestWebService

    public partial class WebForm1 : System.Web.UI.Page

        protected void Page_Load(object sender, EventArgs e)
        {
            using (TestWebService1SoapClient client = new TestWebService1SoapClient())
            {
                MySoapHeader myHeader = new MySoapHeader();
                myHeader.UserName = "admin";
                myHeader.Password = "123";//用户名和密码要和调用的Web Service 一致
                Response.Write(client.HelloWorld(myHeader, "yxl") + "</br>");
                Response.Write("<hr/>");
                Student[] students = client.GetStudent();
                foreach (var student in students)
                {
                    Response.Write(student.Name+"</br>");
                }
                Response.Write("<hr/>");

                foreach (var student in client.GetStudentResultByStudentList(students))
                {
                    Response.Write(student.Name + "</br>");
                }
            }
