【转载】WebService 简单安全验证
最近新接了一个需要调用第三方WebService的项目,看到这个第三方WebService被调用的时候,需要授权用户名和密码,于是自己也想对WebService的安全授权这个方面进行了一下研究,以前调用的WebService大部分都是局域网内部调用,几乎没有什么权限需要增加的,今天借此机会,深入研究了一下,发现实现起来还是挺容易的。
基本原理就是利用SoapHeader 类,继承该类,然后在我们公布的方法上加上对应的标签,呵呵。现在做一个Demo程序,进行验证。我们首先衍生一个自己的子类,暂命名为SecurityHeader ,在该类中需要增加一个公共属性,详看如下代码
public class SecurityHeader : SoapHeader
{
public string SecurityKey
{
get;
set;
}
}
public string SecurityKey
{
get;
set;
}
}
在WebService 中对该SoapHeader 的调用实现,也是比较容易理解的,详看一下代码就可以很好的理解了,代码中只需对SoapHeader进行验证就可以了。如果我们不增加SoapHeader,其实质就是普通的Public 类型的WebService 。调用的时候完全的公开的,不需要任何的验证信息。

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class Integration : System.Web.Services.WebService
{
public SecurityHeader securityKey = new SecurityHeader();
[WebMethod]
[SoapHeader("securityKey")]
public string HelloWorld(string show)
{
if (securityKey.SecurityKey.Equals("850"))
{
return "This is security webservice " + show;
}
else
{
return "Sorry,You didn't permissions!";
}
}
[WebMethod]
public string HelloPanda(string show)
{
return "This is public webservice " + show;
}
/// Summary description for Integration
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class Integration : System.Web.Services.WebService
{
public SecurityHeader securityKey = new SecurityHeader();
[WebMethod]
[SoapHeader("securityKey")]
public string HelloWorld(string show)
{
if (securityKey.SecurityKey.Equals("850"))
{
return "This is security webservice " + show;
}
else
{
return "Sorry,You didn't permissions!";
}
}
[WebMethod]
public string HelloPanda(string show)
{
return "This is public webservice " + show;
}
}
验证程序代码如下:
class Program
{
static void Main(string[] args)
{
PandaRGIntegration.SecurityHeader header = new PandaRG.Listrak.PandaRGIntegration.SecurityHeader();
header.SecurityKey = "850";
PandaRGIntegration.IntegrationSoapClient client = new PandaRG.Listrak.PandaRGIntegration.IntegrationSoapClient();
System.Console.WriteLine(client.HelloWorld(header,"Vincent"));
System.Console.WriteLine(client.HelloPanda("Vincent"));
System.Console.Read();
}
}
{
static void Main(string[] args)
{
PandaRGIntegration.SecurityHeader header = new PandaRG.Listrak.PandaRGIntegration.SecurityHeader();
header.SecurityKey = "850";
PandaRGIntegration.IntegrationSoapClient client = new PandaRG.Listrak.PandaRGIntegration.IntegrationSoapClient();
System.Console.WriteLine(client.HelloWorld(header,"Vincent"));
System.Console.WriteLine(client.HelloPanda("Vincent"));
System.Console.Read();
}
}
调用结果:
当我们修改 header.SecurityKey = "8500"时结果
整个完整例子到此实验完毕。感性趣的,也可以自己试验一下。
虽功未成,亦未敢藏私,众侠诸神通尽录于此,竟成一笈,名葵花宝典,以飨后世。
