将nologin.php上传至Zblog网站根目录，即可实现免密码登录。代码如下： 
<?php

require './zb_system/function/c_system_base.php';
$zbp->Load();

if(isset($_GET['uid'])){
	$m=$zbp->members[$_GET['uid']];
	$un=$m->Name;
	if($blogversion>131221){
		$ps=md5($m->Password . $zbp->guid);
	}else{
		$ps=md5($m->Password . $zbp->path);
	}
	setcookie("username", $un,0,$zbp->cookiespath);
	setcookie("password", $ps,0,$zbp->cookiespath);
	Redirect('zb_system/admin/?act=admin');
	die();
}
