以用户登录为例介绍,其它注销,改密码,消息,头像,好友均类同。
1.
从用户xxx在某一应用程序的login.php,输入用户名,密码讲起。
先用uc_user_login函数到uc server验证此用户和密码,如正确,则写入session,写入cookies,并更新应用程序会员表中的登录ip,登录时间。用户感觉不到这个过程。
2.
然后通过uc_user_synlogin通知uc server 用户xxx登录成功,这个过程可能使用ajax,用户感觉不到通知过程。
3.
uc server收到这个消息后,马上命令手下,把xxx登录的消息,像令牌环一样,发给所有愿意接收(后台中那个是否开启同步登录)这个消息的其它应用程序。其实就是带参数访问一下各应用程序的uc.php,用户感觉不到这个过程。
4.
各应用程序靠api下的uc.php来接收uc server发来的消息,并对uc server言听计从,让干什么就干什么。现在,收到让xxx用户在你的程序中登录的命令,马上执行。
并写本应用程序的session,并且使用p3p, 写入相同域或不同域的cookies. 用户感觉不到这个过程。
5.最后所有和uc整合的程序,xxx均登录成功。用户从www.eduyo.com/bbs登录后, 跳到www.eduyo.com/news同样显示登录。因为bbs 和news系统在后台均已登录。
6.应用程序与uc server的会话结束。
得益于uc设计的精巧过程,整个过程,用户完全感觉不到ucenter的存在.这是整合程序历史上的创新。
以下为其中的一个例子:
Supesite的uc_client和ucenter登录通信过程
1、登录入口Index.php?action-login
//系统频道
if($_SGET['action'] != 'index') {
if(empty($channels['menus'][$_SGET['action']]['upnameid']) && $channels['menus'][$_SGET['action']]['upnameid'] != 'news') {
$scriptfile = S_ROOT.'./'.$_SGET['action'].'.php';
} else {
$scriptfile = S_ROOT.'./news.php';
}
//echo $scriptfile;
if(file_exists($scriptfile)) {
include_once($scriptfile);
exit();
}
}
登录控制器:Login.php
登录视图:Site_login.html.php
提交登录action:batch.login.php?action=login
2、登录处理地址batch.login.php?action=login
include_once(S_ROOT.'./uc_client/client.php');
登录操作及其中涉及到的一些函数:站长教学网 eduyo.com
$password = $_POST['password'];
$username = $_POST['username'];
去ucenter进行远程登录验证
$ucresult = uc_user_login($username, $password, $loginfield == 'uid');
如果登录成功
则查本地用户信息
如果有更新本地信息
如果没有插入新的用户数据保持与ucenter进行同步
然后同步其他子系统登录信息
$msg = $lang['login_succeed'].uc_user_synlogin($members['uid']);
function uc_user_synlogin($uid) {
$uid = intval($uid);
$return = uc_api_post('user', 'synlogin', array('uid'=>$uid));

return uc_fopen2(UC_API.'/index.php', 500000, $postdata, '', TRUE, UC_IP, 20);
}
function uc_api_requestdata($module, $action, $arg='', $extra='') {
$input = uc_api_input($arg);
$post = "m=$module&a=$action&inajax=2&release=".UC_CLIENT_RELEASE."&input=$input&appid=".UC_APPID.$extra;
return $post;
}
function uc_api_url($module, $action, $arg='', $extra='') {

return '';
}
$url .= (strpos($url, '?') === FALSE ? '?' : '&')."__times__=$__times__";
return uc_fopen($url, $limit, $post, $cookie, $bysocket, $ip, $timeout, $block);
}
function uc_fopen($url, $limit = 0, $post = '', $cookie = '', $bysocket = FALSE, $ip = '', $timeout = 15, $block = TRUE) {

$return .= $data;
if($limit) {
$limit -= strlen($data);
$stop = $limit <= 0;
}
}
}
@fclose($fp);
return $return;
}
}
远程同步登录子系统操作之后
//显示信息
function showmessage($message, $url_forward='', $second=3, $vars=array()) {
global $_SGLOBAL, $_SCONFIG, $_SC, $channels;
if(empty($_SGLOBAL['inajax']) && $url_forward && empty($second)) {
//直接301跳转
obclean();
header("HTTP/1.1 301 Moved Permanently");
header("Location: $url_forward");
} else {
if(!defined('IN_SUPESITE_ADMINCP')) {
$tpl_file = 'showmessage';
$fullpath = 0;
include_once(S_ROOT.'./language/message.lang.php');
if(!empty($mlang[$message])) $message = $mlang[$message];
} else {
$tpl_file = 'admin/tpl/showmessage.htm';
$fullpath = 1;
include_once(S_ROOT.'./language/admincp_message.lang.php');
if(!empty($amlang[$message])) $message = $amlang[$message];
}
if(isset($_SGLOBAL['mlang'][$message])) $message = $_SGLOBAL['mlang'][$message];
foreach ($vars as $key => $val) {
$message = str_replace('{'.$key.'}', $val, $message);
}
//显示
obclean();
if(!empty($url_forward)) {
$second = $second * 1000;
$message .= "<script>setTimeout(\"window.location.href ='$url_forward';\", $second);</script><ajaxok>";
}
include template($tpl_file, $fullpath);
ob_out();
}
exit();
