《PHP實(shí)戰(zhàn)：PHP編程 SSO詳細(xì)介紹及簡(jiǎn)單實(shí)例》要點(diǎn)：
本文介紹了PHP實(shí)戰(zhàn)：PHP編程 SSO詳細(xì)介紹及簡(jiǎn)單實(shí)例，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。
PHP實(shí)例PHP SSO詳解
PHP實(shí)例SSO有三種模式:①跨子域單點(diǎn)登陸②完全跨單點(diǎn)域登陸③站群共享身份認(rèn)證
PHP實(shí)例第一種模式很簡(jiǎn)單,只需要將Cookie的域設(shè)置成多個(gè)應(yīng)用的根域即可
PHP實(shí)例第二種方式,也很簡(jiǎn)單,就是將所以應(yīng)用的認(rèn)證地址更換成同一個(gè)認(rèn)證地址,每次查看是否在認(rèn)證中心登陸,如果登陸了,給調(diào)用應(yīng)用發(fā)放一個(gè)加密令牌即可
PHP實(shí)例第三種跨域,就是來回跳轉(zhuǎn)來回驗(yàn)證token略有麻煩
PHP實(shí)例配置目錄結(jié)構(gòu)
PHP實(shí)例在服務(wù)器根目錄下,新建三個(gè)項(xiàng)目目錄:
PHP實(shí)例|C/網(wǎng)站根目錄/
|C|C/oa/
|C|C/bbs/
|C|C/blog/
PHP實(shí)例在根目錄下新建functions.PHP腳本文件,具體內(nèi)容如下:
PHP實(shí)例
<?php
/**
* 獲取登陸token
* @param string $url 獲取token的地址
* 2017-01-03T13:08:43+0800
*/
function getToken($url)
{
$bool = isLogin();
if ($bool) {
// 如果登陸了跳轉(zhuǎn)到本站首頁(yè)
header('location: index.php');
exit();
}
// 否則沒有登陸,去另一個(gè)站點(diǎn)看是否登陸
header('location: '.$url);
}
// 校驗(yàn)令牌是否正確
function yzToken($domain)
{
$url = isset($_GET['url']) ? $_GET['url'] : '';
$username = isset($_GET['username']) ? $_GET['username'] : '';
$token = isset($_GET['token']) ? $_GET['token'] : '';
if (!empty($username) && !empty($token)) {
$salt = 'taoip';
$_token = md5($salt.$username);
// 校驗(yàn)第三方站點(diǎn)過來時(shí)的token是否正確
if ($_token == $token) {
// 設(shè)置跳轉(zhuǎn)過來的網(wǎng)站的Cookie
setCook($username, $_token, $domain);
header('location: index.php');
}
}
}
// 設(shè)置cookie
function setCook($username, $_password, $domain)
{
// 校驗(yàn)成功,開始登陸
setcookie('username', $username, time()+3600, '/', $domain);
setcookie('token', $_password, time()+3600, '/', $domain);
header('location: index.php');
}
// 判斷是否登陸
function isLogin()
{
$username = isset($_COOKIE['username']) ? $_COOKIE['username'] : '';
$token = isset($_COOKIE['token']) ? $_COOKIE['token'] : '';
$salt = 'taoip';
$_token = md5($salt.$username);
if ($token == $_token) {
return true;
} else {
return false;
}
}
?>
PHP實(shí)例在oa項(xiàng)目目錄下,新建index.php和login.php兩個(gè)腳本文件
PHP實(shí)例編輯index.php文件
PHP實(shí)例
<?php
// OA站點(diǎn)
// (1)開啟Session會(huì)話

session_start();
// (2)獲取用戶名和token進(jìn)行校驗(yàn)

$token = isset($_COOKIE['token']) ? $_COOKIE['token'] : '';
$salt = 'taoip';
$_token = md5($salt.$username);
if ($token != $_token) {
header('location: login.php');
exit();
}
echo "歡迎{$username}用戶,訪問OA站點(diǎn)";
?>
PHP實(shí)例編輯login.php文件
PHP實(shí)例
<?php

// (2)驗(yàn)證
yzToken('taoip.cn');

$url = isset($_GET['url']) ? $_GET['url'] : '';

PHP實(shí)例配置本地虛擬主機(jī)
PHP實(shí)例具體配置步驟,我想大家應(yīng)該都會(huì)了,不需要我一一贅述.你只需要按照我給的參照,配置和不同域名對(duì)應(yīng)目錄的映射即可.
PHP實(shí)例域名 /項(xiàng)目目錄/
oa.taoip.cn /oa/
bbs.taoip.cn /bbs/
dengpeng.cc /blog/
PHP實(shí)例恭喜您,已經(jīng)完成了一個(gè)簡(jiǎn)單的SSO系統(tǒng)
PHP實(shí)例配置完成后,記得重啟Web服務(wù)器.然后你只需要訪問這三個(gè)不同的站點(diǎn),即可實(shí)現(xiàn)一個(gè)站點(diǎn)登陸,其他站點(diǎn)不再發(fā)送登陸請(qǐng)求.
PHP實(shí)例感謝閱讀,希望能幫助到大家,謝謝大家對(duì)本站的支持!
