WebService身份验证

Web Service身份验证解决方案一：通过通过SOAP Header身份验证。

1.我们实现一个用于身份验证的类，文件名MySoapHeader.cs

MySoapHeader类继承自System.Web.Services.Protocols.SoapHeader。且定义了两个成员变量，UserName和PassWord，还定义了一个用户认证的函数ValideUser。它提供了对UserName和PassWord检查的功能

 
 

using?System; ?
  
  
using?System.Data; ?
  
  
using?System.Configuration; ?
  
  
using?System.Web; ?
  
  
using?System.Web.Security; ?
  
  
using?System.Web.UI; ?
  
  
using?System.Web.UI.HtmlControls; ?
  
  
using?System.Web.UI.WebControls; ?
  
  
using?System.Web.UI.WebControls.WebParts; ?
  
  
using?System.Web.Services; ?
  
  
using?System.Web.Services.Protocols; ?
  
  
///? ?
  
  
///MySoapHeader?的摘要说明 ?
  
  
///? ?
  
  

public?class?MySoapHeader:SoapHeader ?

  
  
{ ?
  
  
????public?MySoapHeader() ?
  
  
????{ ?
  
  
????????// ?
  
  
????????//TODO:?在此处添加构造函数逻辑 ?
  
  
????????// ?
  
  
????} ?
  
  
????public?string?UserName; ?
  
  
????public?string?PassWord; ?
  
  
????public?bool?ValideUser(string?in_UserName,?string?in_PassWord)??? ?
  
  
????{ ?
  
  

????????if?((in_UserName?==?"zxq")?&&?(in_PassWord?==?"123456")) ?

  
  
????????{ ?
  
  
????????????return?true; ?
  
  
????????} ?
  
  
????????else ?
  
  
????????{ ?
  
  
????????????return?false; ?
  
  
????????} ?
  
  
????} ?
  
  
}?
 
 

2.下面我们创建WebService.asmx??? WebService.cs代码如下:

using?System.Collections; ?
  
  
using?System.Web; ?
  
  
?
  
  
///? ?
  
  
///WebService?的摘要说明 ?
  
  
///? ?
  
  

[WebService(Namespace?=?"http://tempuri.org/")] ?

  
  

[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();? ?
  
  
????} ?
  
  

????public?MySoapHeader?header;?////定义用户身份验证类变量header ?

  
  

????[WebMethod(Description?=?"用户验证测试")] ?

  
  

????[System.Web.Services.Protocols.SoapHeader("header")]//用户身份验证的soap头? ?

  
  
????public?string?HelloWorld(string?contents) ?
  
  
????{ ?
  
  
????????//验证是否有权访问? ?
  
  
????????if?(header.ValideUser(header.UserName,?header.PassWord)) ?
  
  
????????{ ?
  
  
????????????return?contents?+?"执行了"; ?
  
  
????????{ ?
  
  
????????????return?"您没有权限访问"; ?
  
  
} ?
 
 

3.客户端 创建个Default.aspx

 
 

Default.aspx?.cs代码 ?
  
  
?
  
  
using?System; ?
  
  
using?System.Configuration; ?
  
  
using?System.Data; ?
  
  
using?System.Web; ?
  
  
using?System.Web.Security; ?
  
  
using?System.Web.UI; ?
  
  
using?System.Web.UI.HtmlControls; ?
  
  
using?System.Web.UI.WebControls; ?
  
  
using?System.Web.UI.WebControls.WebParts; ?
  
  
?
  
  
public?partial?class?_Default?:?System.Web.UI.Page? ?
  
  
{ ?
  
  
????protected?void?Page_Load(object?sender,?EventArgs?e) ?
  
  
????{ ?
  
  

????????com.cn1yw.WebService?test?=?new?com.cn1yw.WebService();//web引用(改成您自己的) ?

  
  

????????com.cn1yw.MySoapHeader?Header?=?new?com.cn1yw.MySoapHeader();//web引用创建soap头对象(改成您自己的) ?

  
  
????????//设置soap头变量 ?
  
  

????????Header.UserName?=?"zxq"; ?

  
  

????????Header.PassWord?=?"123456"; ?

  
  

????????test.MySoapHeaderValue?=?Header; ?

  
  
????????//调用web?方法 ?
  
  
????????Response.Write(test.HelloWorld("我是强")); ?
  
  
????} ?
  
  
}?
 
 

Web Service身份验证解决方案二：通过集成windows身份验证。

1. 将web服务程序设为集成windows身份验证

2.客户端web引用代码?

Test.WebReference.Service1?wr?=?new?Test.WebReference.Service1();?//生成web?service实例? ?
  
  

wr.Credentials?=?new?NetworkCredential("guest","123");?//guest是用户名，该用户需要有一定的权限? ?

  
  

lblTest.Text?=?wr.Add(2,2).ToString();?//调用web?service方法??

 
 

该方案的优点是比较安全，性能较好，缺点是不便于移植，部署工作量大。
