一、通过SOAP Header身份验证

此方法是通过设置SOAP Header信息来验证身份，主要通过以下几步：

1、在服务端实现一个SOAP Header类

public class CredentialSoapHeader : System.Web.Services.Protocols.SoapHeader

{    //验证身份的用户名    public string UserId    {        get;        set;    }    //验证身份的密码    public string Password    {        get;        set;    }}

2、创建WebService

[WebService(Namespace=)]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]public class WebService : System.Web.Services.WebService{    public WebService()    {        //如果使用设计的组件，请取消注释以下行        //InitializeComponent();    }     //生成一个CredentialSoapHeader类的实例    public CredentialSoapHeader header;    [WebMethod(Description="用户验证测试")]    [System.Web.Services.Protocols.SoapHeader("header")] //用户身份验证的soap header    public string HelloWorld(string contents)    {        //验证是否有权访问（当然，也可以通过查询数据库实现，具体视项目要求）        if(header.UserId.equals("admin") && header.Password.equals("admin"))        {            return "Hello World " + contents;        }        else        {            return "无权使用此服务";        }    }}

3、调用WebService

protected void Button1_Click(object sender, EventArgs e)

{    localhost.WebService service = new localhost.WebService();    localhost.CredentialSoapHeader header = new localhost.CredentialSoapHeader();    //设置SOAP Header    Header.UserId = "admin";    Header.Password = "admin";    service.CredentialSoapHeader = header;    //调用Web方法    Response.Write(service.HelloWorld("测试"));}

 

二、通过集成windows身份验证

1、将WebService设为集成Windows身份验证

2、客户端引用代码

localhost.WebService service = new localhost.WebService();

service.Credentials = new NetworkCredential("guest","123"); //guest是用户名，123是密码string result = service.HelloWorld("测试");
