PHP編程 SSO詳細(xì)介紹及簡(jiǎn)單實(shí)例

更新時(shí)間：2017年01月13日 15:36:32 投稿：lqh

這篇文章主要介紹了PHP編程 SSO詳細(xì)介紹及簡(jiǎn)單實(shí)例的相關(guān)資料,這里介紹了三種模式跨子域單點(diǎn)登陸、完全跨單點(diǎn)域登陸、站群共享身份認(rèn)證,需要的朋友可以參考下

PHP SSO詳解

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

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

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

第三種跨域,就是來(lái)回跳轉(zhuǎn)來(lái)回驗(yàn)證token略有麻煩

配置目錄結(jié)構(gòu)

在服務(wù)器根目錄下,新建三個(gè)項(xiàng)目目錄:

|–/網(wǎng)站根目錄/
|–|–/oa/
|–|–/bbs/
|–|–/blog/

在根目錄下新建functions.PHP腳本文件,具體內(nèi)容如下:

<?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(méi)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.$username);
    // 校驗(yàn)第三方站點(diǎn)過(guò)來(lái)時(shí)的token是否正確
    if ($_token == $token) {
      // 設(shè)置跳轉(zhuǎn)過(guò)來(lái)的網(wǎng)站的Cookie
      setCook($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;
  }
}

?>

在oa項(xiàng)目目錄下,新建index.php和login.php兩個(gè)腳本文件

編輯index.php文件

<?php

$username = isset($_COOKIE['username']) ? $_COOKIE['username'] : '';
$token = isset($_COOKIE['token']) ? $_COOKIE['token'] : '';

$salt = 'taoip';

$_token = md5($salt.$username);

if ($token != $_token) {
  header('location: login.php');
  exit();

  // 從庫(kù)中查詢用戶密碼

  mysql_query('use sso', $link);

    if (empty($url)) {
      header('location: index.php');
    } else {

    }

配置本地虛擬主機(jī)

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.

域名 /項(xiàng)目目錄/
oa.taoip.cn /oa/
bbs.taoip.cn /bbs/
dengpeng.cc /blog/

恭喜您,已經(jīng)完成了一個(gè)簡(jiǎn)單的SSO系統(tǒng)

配置完成后,記得重啟Web服務(wù)器.然后你只需要訪問(wèn)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.

感謝閱讀，希望能幫助到大家，謝謝大家對(duì)本站的支持！
