WebService 用户名密码验证
在项目开发的过程中,WebService是经常要用的,当调用WebService方法时,需要经过服务的验证才可以调用,一般就是用户名/密码验证,还有一个就是证书.下面程序使用的是用户名/密码的方式,很简单的一个程序.

先看服务端的代码(ws_Service)
MySoapHeader.cs 这里通过继承SoapHeader实现对用户名/密码的验证
public class MySoapHeader:System.Web.Services.Protocols.SoapHeader
{
private string userID = string.Empty;
private string userPW = string.Empty;
public string UserId
{
get { return userID; }
set { userID = value; }
}
public string UserPW
{
get { return userPW; }
set { userPW = value; }
}
public MySoapHeader()
{ }
public MySoapHeader(string name, string password)
{
userID = name;
userPW = password;
}
private bool IsValid(string nUserId, string nPassWord, out string nMsg)
{
nMsg = "";
try
{
if (nUserId == "admin" && nPassWord == "admin")
{
return true;
}
else
{
nMsg = "对不起,你无权调用Web服务";
return false;
}
}
catch
{
nMsg = "对不起,你无权调用Web服务";
return false;
}
}
public bool IsValid(out string nMsg)
{
return IsValid(userID,userPW,out nMsg);
}
}
Service1.asmx文件代码:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{
public MySoapHeader myHeader = new MySoapHeader();
[WebMethod]
public string GetMsg()
{
Thread.Sleep(5000);
return "Hello World";
}
[SoapHeader("myHeader")]
[WebMethod(Description="获取用户列表")]
public string GetMain()
{
string msg = "";
if (!myHeader.IsValid(out msg))
{
return msg;
}
return "Main";
}
}
这里面有两个方法,其中GetMsg方法是不需要验证的,而GetMain方法需要进行用户名/密码的验证,这个可以在客户端调用时进行验证.
客户端添加对服务端的引用…
Program.cs文件
class Program
{
static void Main(string[] args)
{
localhost.Service1SoapClient proxy = new ws_Client.localhost.Service1SoapClient();
MySoapHeader header = new MySoapHeader();
header.UserId = "admin";
header.UserPW = "admin";
string result = proxy.GetMain(header);
//string result = proxy.GetMsg();
Console.WriteLine(result);
Console.ReadKey();
}
}
