调用WebService时加入身份验证，以拒绝未授权的访问
众所周知，WebService是为企业需求提供的在线应用服务,其他公司或应用软件能够通过Internet来访问并使用这项在线服务。但在有些时候的某些应用服务不希望被未授权访问，那么此时我们可以一下几种方法来实现身份验证。
方法一：在WebService中引入SoapHeader
view plaincopy to clipboardprint?
#region 配置登录标头
/// <summary>
/// Code CreateBy BanLao
/// </summary>
public class MySoapHeader : SoapHeader
{
private string strUserName = string.Empty;
private string strPassWord = string.Empty;
public MySoapHeader() { }
public MySoapHeader(string username, string password)
{
this.strUserName = username;
this.strPassWord = password;
}
#region 构造 用户名|密码
/// <summary>
/// 用户名
/// </summary>
public string UserName
{
get { return strUserName; }
set { strUserName = value; }
}
/// <summary>
/// 密码
/// </summary>
public string PassWord
{
get { return strPassWord; }
set { strPassWord = value; }
}
#endregion
#region 检测是否正确登录
/// <summary>
/// 检测是否正确登录
/// </summary>
/// <returns></returns>
public bool CheckLogin()
{
if (strUserName == "合法登录名" && strPassWord == "合法登录密码")
{
return true;
}
else
{
return false;
}
}
#endregion
}
#endregion
#region 配置登录标头
/// <summary>
/// Code CreateBy BanLao
/// </summary>
public class MySoapHeader : SoapHeader
{
private string strUserName = string.Empty;
private string strPassWord = string.Empty;
public MySoapHeader() { }
public MySoapHeader(string username, string password)
{
this.strUserName = username;
this.strPassWord = password;
}
#region 构造 用户名|密码
/// <summary>
/// 用户名
/// </summary>
public string UserName
{
get { return strUserName; }
set { strUserName = value; }
}
/// <summary>
/// 密码
/// </summary>
public string PassWord
{
get { return strPassWord; }
set { strPassWord = value; }
}
#endregion
#region 检测是否正确登录
/// <summary>
/// 检测是否正确登录
/// </summary>
/// <returns></returns>
public bool CheckLogin()
{
if (strUserName == "合法登录名" && strPassWord == "合法登录密码")
{
return true;
}
else
{
return false;
}
}
#endregion
}
#endregion
加入一个服务用于测试：
view plaincopy to clipboardprint?
#region 测试连接
[System.Web.Services.Protocols.SoapHeader("myHeader")]
[WebMethod(Description = "判断用户是否开通", EnableSession = true)]
public string _GetValue(string strInputValue)
{
if (myHeader.CheckLogin())
{
string strReturnValue = strInputValue + "@CopyRight By BanLao 2010";
return strReturnValue;
}
else
{
return "无效的身份验证，请重试！";
}
}
#endregion
#region 测试连接
[System.Web.Services.Protocols.SoapHeader("myHeader")]
[WebMethod(Description = "判断用户是否开通", EnableSession = true)]
public string _GetValue(string strInputValue)
{
if (myHeader.CheckLogin())
{
string strReturnValue = strInputValue + "@CopyRight By BanLao 2010";
return strReturnValue;
}
else
{
return "无效的身份验证，请重试！";
}
}
#endregion
至此我们想要的需要通过身份验证的服务配置好了，下面让我们进行一些测试，新建一个webForm在Page_Load中：
view plaincopy to clipboardprint?
WebLogon.MySoapHeader myHeader = new WebLogon.MySoapHeader();
myHeader.UserName = "约定的合法用户";
myHeader.PassWord = "约定的合法密码";
WebLogon.Service This_Service = new WebLogon.Service();
This_Service.MySoapHeaderValue = myHeader;
Response.Write(This_Service._GetValue("This is BanLao's Test Application For SoapHeader. "));
WebLogon.MySoapHeader myHeader = new WebLogon.MySoapHeader();
myHeader.UserName = "约定的合法用户";
myHeader.PassWord = "约定的合法密码";
WebLogon.Service This_Service = new WebLogon.Service();
This_Service.MySoapHeaderValue = myHeader;
Response.Write(This_Service._GetValue("This is BanLao's Test Application For SoapHeader. "));
当运行这个WebForm时，如果用户名和密码是正确的我们将看到:
This is BanLao's Test Application For SoapHeader. @CopyRight By BanLao 2010
否则
无效的身份验证，请重试！
方法二：Web Service以Session方式验证
view plaincopy to clipboardprint?
[WebMethod(Description = "检测是否正确登录", EnableSession = true)]
public bool CheckLogin(string strUserName, string strPassword)
{
if (strUserName.Equals("admin") && strPassword.Equals("123456"))
{
Session["LoginState"] = true;
}
else
{
Session["LoginState"] = false;
}
return (bool)Session["LoginState"];
}
#region 测试连接
[WebMethod(Description = "测试连接", EnableSession = true)]
public string _GetValue(string strInputValue)
{
if (Session["LoginState"] == null || Session["LoginState"].Equals(false))
{
return "无效的身份验证，请重试！";
}
else
{
string strReturnValue = strInputValue + "@CopyRight By BanLao 2010";
return strReturnValue;
}
}
#endregion
[WebMethod(Description = "检测是否正确登录", EnableSession = true)]
public bool CheckLogin(string strUserName, string strPassword)
{
if (strUserName.Equals("admin") && strPassword.Equals("123456"))
{
Session["LoginState"] = true;
}
else
{
Session["LoginState"] = false;
}
return (bool)Session["LoginState"];
}
#region 测试连接
[WebMethod(Description = "测试连接", EnableSession = true)]
public string _GetValue(string strInputValue)
{
if (Session["LoginState"] == null || Session["LoginState"].Equals(false))
{
return "无效的身份验证，请重试！";
}
else
{
string strReturnValue = strInputValue + "@CopyRight By BanLao 2010";
return strReturnValue;
}
}
#endregion
调用该服务，
view plaincopy to clipboardprint?
WebLogon.Service This_Service = new WebLogon.Service();
This_Service.CookieContainer = new System.Net.CookieContainer();
if (This_Service.CheckLogin("admin", "123456"))
{
Response.Write(This_Service._GetValue("This is BanLao's Test Application For Session. "));
}
WebLogon.Service This_Service = new WebLogon.Service();
This_Service.CookieContainer = new System.Net.CookieContainer();
if (This_Service.CheckLogin("admin", "123456"))
{
Response.Write(This_Service._GetValue("This is BanLao's Test Application For Session. "));
}
当运行这个WebForm时，如果用户名和密码是正确的我们将看到:
This is BanLao's Test Application For Session. @CopyRight By BanLao 2010
否则
无效的身份验证，请重试！
注：如果需要多个合法用户，可以在WebService中声明判断即可
