原文:https://github.com/CodeIgniter-Chinese/ucenter-how-to
本文默认你已详细阅读过 UCenter 官方手册并对 CodeIgniter 有一定的了解。
下载相应的软件
简体 UTF-8,可以不下载 Discuz!,这里只是用来最后检验同步登录/登出是否成功。
前置条件
- 项目目录结构如下
- 搭建服务器
根目录指向codeIgniter-ucenter
我设置了hosts这个任意的,这里只是为了突出主题。
开始集成
- 安装 Ucenter
访问http://ci.connect.uc/uc,按照向导安装即可。
- 安装 DiscuzX
访问http://ci.connect.uc/discuz,按照向导,第二步时候选择只安装DiscuzX,如下图,信息填写uc的安装信息
- 配置 CodeIgniter
- 配置application/config.php, 为使用session类,需要设置encryption_key,值任意.
PHP复制代码 $config['encryption_key'] = sha1('whatever it is!'); 复制代码
PHP复制代码 <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index ()
{
$this->load->library('session');
$data['user'] = $this->session->userdata('user');
$this->load->view('welcome_message', $data);
}
} 复制代码
- 修改 views/welcome_message.php中的 div#container 如下:
HTML复制代码 <div id="container">
<h1>Welcome to CodeIgniter! </h1>
<div id="body">
<?php if ($user): ?>
<p>欢迎你, <?php echo $user['username']; ?>到 <a target="_blank" href="http://ci.connect.uc/discuz">DiscuzX </a>退出后再刷新这个页面吧! </p>
<?php else: ?>
<p>尚未登录,到 <a target="_blank" href="http://ci.connect.uc/discuz">DiscuzX </a>登录后再刷新这个页面吧! </p>
<?php endif; ?>
</div>
<p class="footer">Page rendered in <strong>0.0455 </strong> seconds </p>
</div> 复制代码
- 在Ucenter中添加新应用
看图:
- 在CI目录application/config/目录下新建文件ucenter.php
内容为UCenter为新加应用生成的配置文件
PHP复制代码 <?php
define('UC_CONNECT', 'mysql');
define('UC_DBHOST', 'localhost');
define('UC_DBUSER', 'root');
define('UC_DBPW', 'root');
define('UC_DBNAME', 'ucenter');
define('UC_DBCHARSET', 'utf8');
define('UC_DBTABLEPRE', '`ucenter`.uc_');
define('UC_DBCONNECT', '0');
define('UC_KEY', 'whatever you wanna set!');
define('UC_API', 'http://ci.connect.uc/uc');
define('UC_CHARSET', 'utf-8');
define('UC_IP', '');
define('UC_APPID', '2');
define('UC_PPP', '20'); 复制代码
- 从uc安装包中复制uc_client到ci根目录
- 新增控制器api/uc.php
内容如下:
PHP复制代码 <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* Ucenter接口通知处理控制器
*
* 本类根据ucenter提供的通知处理实例代码编写,具体处理部分需要根据不同应用的逻辑自行编写处理逻辑。
* 具体请仔细阅读ucenter自带的手册。

本教程不含自带用户数据库的情况下,在自有用户表的情况下,处理逻辑类似,要有一个字段记录ucenter的唯一用户id,同步登录和退出的逻辑里使用该id进行相应的操作。 |
