asp.net 2.0中傻瓜式使用soap header

在websevrice 中,soap header是十分重要的哦，主要是安全性的考慮，在asp.net 2.0中,可以簡單地應用soap header來
進行傻瓜式的應用，更複雜的應用當然要更深入地去看了,

首先，我們寫個簡單的helloworld的webservice

using System;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

 

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

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

 

public class Service : System.Web.Services.WebService

{

    public ValidationSoapHeader Authentication;

    private const string DEV_TOKEN = "12345";

    public Service()

    {

        //Uncomment the following line if using designed components

        //InitializeComponent();

    }

 

    [SoapHeader("Authentication")]

    [WebMethod]

 

    public string HelloWorld()

    {

        if (Authentication != null && Authentication.DevToken == DEV_TOKEN)

        {

            return "Hello World";

        }

        else

        {

            throw new Exception("Authentication Failed");

        }

    }

}

可以看到，首先必須在[webmethod]前添加[SoapHeader("Authentication")]，這裡我們判斷來自用戶端的soap header是否有效，並且看其tokern是否等於我們預先定義好的token,如果是的話就輸出hello world,否則拋出異常
這裡我們編寫一個ValidationSoapHeader類，其中是繼承了soap header,如下

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;

using System.Web.Services.Protocols;

 

/// <summary>

/// Summary description for ePhoneCredentials

/// </summary>

public class ValidationSoapHeader : SoapHeader

{

    private string _devToken;

    public ValidationSoapHeader()

    {
    }

    public ValidationSoapHeader(string devToken)

    {

        this._devToken = devToken;

    }

    public string DevToken

    {

        get { return this._devToken; }

        set { this._devToken = value; }

    }

}
這裡只不過是一些屬性的設定讀取，然後編寫一個用戶端，如下，顯式指定要傳遞soap header

//ConsoleMyCsharpClient是建立用戶端的工程名
localhost.ValidationSoapHeader header = new ConsoleMyCsharpClient.localhost.ValidationSoapHeader();

header.DevToken = "12345";

localhost.Service ws = new ConsoleMyCsharpClient.localhost.Service();

ws.ValidationSoapHeaderValue = header;

Console.WriteLine(ws.HelloWorld());
Console.ReadLine();

這樣，當用戶端傳遞12345給WS後，能正確顯示HELLO WORLD，否則不能正確顯示
