UCenter 的中文意思就是“用户中心”，其中的 U 代表 User 也代表 You ，取其中的含义就是“用户中心”，或者说“你（最终用户）的中心”。 UCenter 是 Comsenz 旗下各个产品之间信息直接传递的一个桥梁，通过 UCenter站长可以无缝整合 Comsenz 系列产品，实现用户的一站式注册、登录、退出以及社区其他数据的交互的php框架。

下载相应的软件

CodeIgniter 2.1.4

UCenter 1.6.0

Discuz! X3

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

127.0.0.1 ci.connect.uc

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 Discuz!X

访问http://ci.connect.uc/discuz，按照向导，第二步时候选择只安装 Discuz!X，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。

$config['encryption_key'] = sha1('whatever it is!');

修改默认控制器 welcome.php 如下：

load->library('session'); $data['user'] = $this->session->userdata('user'); $this->load->view('welcome_message', $data); } }

修改 views/welcome_message.php 中的div#container如下：

在 UCenter 中添加新应用

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

从 UCenter 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：
