Flex 调用添加了SoapHeader的web service

1.NET中撰写需要使用SoapHeader验证的Web Service

代码1：WebService.cs

using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://www.microsoft.com/")] //名字空间，注意FLEX中调用的时候要手工填写
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
         public class WebService : System.Web.Services.WebService {

         public WebService () {}

         public AuthenticationInfo authenticationInfo;

         [WebMethod]
         [SoapHeader("authenticationInfo")] //为服务添加SoapHeader
         public string HelloWorld() {
                  if (authenticationInfo == null)  {
                           return "验证信息不能为空."
                  }
                  else{
                           if (Authentication.Check(authenticationInfo.username, authenticationInfo.password))  {
                                   return "Hello world!"
                           }
                           else{
                                    return "用户名密码验证失败，你没有权力访问此服务。"
                           }
                  }
         }
}

//用户密码验证类
public class Authentication {
         public static bool Check(string username, string password) {
                 return ((username == "user") && (password == "password"));
         }        
}

 

代码2:AuthenticationInfo.cs

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

/// <summary>
/// AuthenticationInfo 的摘要说明
/// </summary>
public class AuthenticationInfo:System.Web.Services.Protocols.SoapHeader{
         public AuthenticationInfo() { }
         public AuthenticationInfo(string username ,string password)         {
                  this.username = username;
                  this.password = password;
         }
         public string username;
         public string password;
}

 

2 在.NET中调用使用了SoapHeader的Web Service

代码3:Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1{
         public partial class Form1 : Form{
                  public Form1() {
                           InitializeComponent();
                  }
                  private void button1_Click(object sender, EventArgs e){
                           localhost.WebService service = new WindowsApplication1.localhost.WebService();
                           localhost.AuthenticationInfo au = new WindowsApplication1.localhost.AuthenticationInfo();
                           au.username = textBox1.Text;
                           au.password = textBox2.Text;
                           service.AuthenticationInfoValue = au;
                           label3.Text = service.HelloWorld();
                  }
         }
}

 

3 在Flex调用此Web Service

代码4：SoapHeaderTest.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" fontFamily="simsun" fontSize="12">
<mx:Script>
<![CDATA[
        import mx.rpc.events.FaultEvent;
        import mx.rpc.events.ResultEvent;
        import mx.rpc.soap.SOAPHeader;
        private function Invoke():void{
                ws.clearHeaders(); //先清理一下
                var auinfo:Authentication = new Authentication(txtUser.text,txtPassword.text); //
                ws.addHeader(auinfo); //添加
                ws.HelloWorld(); //调用服务
        }
        private function wsResult(event:ResultEvent):void{
                lblInformation.text= event.result.toString();
        }
        private function wsFault(event:FaultEvent):void{
                lblInformation.text= event.message.toString();
        }
]]>
</mx:Script>
<mx:WebService id="ws" wsdl="http://localhost:4443/WebSites/WebService.asmx?WSDL"
result="wsResult(event)" fault="wsFault(event)"/>
<mx:TextInput id="txtUser" x="98" y="94"/>
<mx:TextInput id="txtPassword" x="98" y="124"/>
<mx:Label x="29" y="98" text="User:"/>
<mx:Label x="29" y="128" text="Password:"/>
<mx:Button x="193" y="166" label="Invoke" click="Invoke()"/>
<mx:Label x="29" y="213" text="Label" id="lblInformation"/>
</mx:Application>

代码5:AuthenticationInfo.as

package{
        public class AuthenticationInfo{ //字段名称需和.NET端一致
                public var username:String;
                public var password:String;
        }
}

代码6:Authentication.as

package{
        import mx.rpc.soap.SOAPHeader;

        public class Authentication extends SOAPHeader{
                public var username:String;
                public var password:String;
                public function Authentication(user:String,password:String){
                        var content:AuthenticationInfo = new AuthenticationInfo();
                        content.username = user;
                        content.password = password;
                        var qname:QName = new QName("http://www.microsoft.com/","AuthenticationInfo");
                        super(qname, content);
                }
        }
}
