利用Web Service实现的登陆验证演示(代码调试通过)

本示例完成了利用Web Service实现登陆验证功能,在此基础上可以实现更强大的功能,比如做一个单点登陆(类微软的passport)等

.asmx.cs代码
[WebMethod]
  public bool LoginFlag(string name,string pass){
   bool flag=false;
   if (name.Length>8){
   name=name.Substring(0,8);
   }
   if(pass.Length>8){
   pass=pass.Substring(0,8);
   }
   if (name=="qianqian"&&pass=="888888")
   {
    flag=true;
   }
   return flag;
  }
.aspx代码
<form id="Form1" method="post" runat="server">
   <FONT face="宋体">
    <TABLE id="Table1" style="WIDTH: 360px; HEIGHT: 113px" cellSpacing="1" cellPadding="1"
     width="360" border="1">
     <TR>
      <TD style="WIDTH: 89px"></TD>
      <TD>登陆Web Service演示</TD>
     </TR>
     <TR>
      <TD style="WIDTH: 89px">用户名：</TD>
      <TD>
       <asp:TextBox id="name" runat="server"></asp:TextBox></TD>
     </TR>
     <TR>
      <TD style="WIDTH: 89px">密 码：</TD>
      <TD>
       <asp:TextBox id="pass" runat="server"></asp:TextBox></TD>
     </TR>
     <TR>
      <TD style="WIDTH: 89px"></TD>
      <TD>
       <asp:Button id="loginButton" runat="server" Text="登 陆"></asp:Button></TD>
     </TR>
    </TABLE>
   </FONT>
  </form>

.aspx.cs代码
private void loginButton_Click(object sender, System.EventArgs e)
  {//调用web Service服务
   webServiceShow.localhost.login wss=new webServiceShow.localhost.login();
   if(wss.LoginFlag(name.Text,pass.Text))
   {
    Response.Write("登陆成功");
   }
   else{
    Response.Write("登陆失败");
   }
  }
