?完全適用ASP.NET的認證機制
–可以使用FormsAuthentication
?WebService方法可以操作Cookie
–Impersonation
–PrincipalPermission

aspx
????<form?id="form1"?runat="server">
????????<asp:ScriptManager?runat="server"?ID="ScriptManager1"?ScriptMode="Debug">
????????????<Services>
????????????????<asp:ServiceReference?Path="Services/SecurityService.asmx"?InlineScript="true"?/>
????????????</Services>
????????</asp:ScriptManager>????
????????
????????<input?type="button"?value="Call"?onclick="call()"?/>
????
????????<script?language="javascript"?type="text/javascript">
????????????function?call()
????????????{
????????????????SecurityService.HelloWorld(onSucceeded);
????????????}
????????????
????????????function?onSucceeded(result)
????????????{
????????????????alert(result);
????????????}
????????</script>????
????</form>
cs
????protected?void?Page_Load(object?sender,?EventArgs?e)
????{
????????FormsAuthentication.SetAuthCookie("Jeffrey?Zhao",?false);
????} 如果不加上這一句，WebService就會跑出異常“Please log in first”

SecurityService.asmx
<%@?WebService?Language="C#"?Class="SecurityService"?%>
