黑莓passport discuz Passport 通行证 整合笔记

//该文档保存为login.php

//首先将接口技术文档里的加密解密函数拷贝

//为了不让代码太乱，我拷贝到文档的结尾处

//假设自己的用户数据库表里用户名字段为UserName, 密码字段为Pwd, Email字段为 Email

//注册页实现方法差不多，可自行实现，疑问加我QQ:2666556

$act=(isset($_GET[‘act’]))?$_GET[‘act’]:”login”;

if(function_exists($act)) $act();else login();

function login()

{

$ErrMsg=UserCheck();

if($ErrMsg!=””)echo $ErrMsg;

//后面加上显示你的登陆表单的代码 如

?>用户名:

密码:

<?php

}//end function

function logout()//登出

{

$passportkey=”1234567890″;//这里换成你论坛通行证设置的passportkey

$auth=$_COOKIE[‘auth’];

setcookie(“auth”, “”,time() – 3600);

$forward=$_GET[‘forward’];

if($forward==””)$forward=”../../index.php”;//这里换成你的主页绝对地址或相对地址

$verify = md5(‘logout’.$auth.$forward.$passportkey);

$auth=rawurlencode($auth);

$forward=rawurlencode($forward);

//===========验证输入=====================

if(!isset($_POST[‘submit’])) return; // login表单的按钮需要与此同名

$usnm=$_POST[‘username’];//username换成你登陆表单里的用户名域

$pwd=$_POST[‘password’];//password换成你登陆表单里的密码域

if($usnm==””) return “请输入用户名!”;

if($pwd==””) return “请输入密码!”;

//=========数据库处理==========================

$db=mysql_connect(“localhost”, “root”, “”);

//==============header到bbs=====================
