我的网页上有简单的登录表单。它使用javascript登录用户并且工作正常。问题是用户直接在地址栏中输入登录页面网址,他可以直接访问该页面而无需登录。如果他没有登录,我想将他重定向到登录页面。以下是loding和target page的链接。

登录:http ://samdesign.comli.com/protected/index.html

目标:http ://samdesign.comli.com/protected/user-soft.html

这是使用的脚本如下..

<form>
<table align=center>
  <tr>
     <td>Username:</td>
     <td><input type="text" name="username" style="background:#bfbfbf;color:#212121;border-color:#212121;" onFocus="this.style.background = '#ffffff';" onBlur="this.style.background = '#bfbfbf';"></td>
  </tr>

  <tr>
     <td>Password:</td>
     <td><input type="password" name="password" style="background:#bfbfbf;color:#212121;border-color:#212121;" onFocus="this.style.background = '#ffffff';" onBlur="this.style.background = '#bfbfbf';"></td>
  </tr>

  <tr>
  <td></td>
  <td align=right><input type="button" value="Login" onClick="Login(this.form);" style="background:#bfbfbf;color:#000000;border-color:#212121;" onMouseOver="this.style.color = '#404040';" onMouseOut="this.style.color = '#000000';" onFocusr="this.style.color = '#404040';" onBlur="this.style.color = '#000000';"></td>
  </tr>
</table>
</form>

脚本是这个

function Login(form) {
username = new Array("numair","sam","u3","u4","u5","u6","u7","u8","u9","u10","temporary");
password = new Array("nk1994","sf1993","p3","p4","p5","p6","p7","p8","p9","p10","user");
page = "/protected/user-soft.html";
if (form.username.value == username[0] && form.password.value == password[0] || form.username.value == username[1] && form.password.value == password[1] || form.username.value == username[2] && form.password.value == password[2] || form.username.value == username[3] && form.password.value == password[3] || form.username.value == username[4] && form.password.value == password[4] || form.username.value == username[5] && form.password.value == password[5] || form.username.value == username[6] && form.password.value == password[6] || form.username.value == username[7] && form.password.value == password[7] || form.username.value == username[8] && form.password.value == password[8] || form.username.value == username[9] && form.password.value == password[9] || form.username.value == username[10] && form.password.value == password[10]) {
self.location.href = page;
}
else {
alert("Either the username or password you entered is incorrect.\nPlease try again.");
form.username.focus();
}
return true;
}

任何人都可以帮忙吗?

// Put this in your login function, just before the redirect
var sessionTimeout = 1; //hours
var loginDuration = new Date();
loginDuration.setTime(loginDuration.getTime()+(sessionTimeout*60*60*1000));
document.cookie = "CrewCentreSession=Valid; "+loginDuration.toGMTString()+"; path=/";


// Put this at the top of index page
if (document.cookie.indexOf("CrewCentreSession=Valid") == -1) {
  location.href = "/Login.html";
}

这不是进行身份验证的正确方法,您必须在服务器端保留身份验证逻辑,您可以在服务器端使用Node.js/Ruby-on-Rails(ROR)/JSP/ASP.NET(等任何您想要的)。

为了使您的页面安全,您必须在服务器端过滤器之前添加(这将检查用户的会话)。

JavaScript 身份验证??这不安全。所有身份验证都应在服务器端完成。
