  1 | # CodeIgniter 整合 UCenter 全攻略
  2 | 
  3 | > 本文默认你已详细阅读过 UCcenter 官方手册并对 CodeIgniter 有一定的了解。
  4 | 
  5 | ## 下载相应的软件
  6 | 
  7 | * [CodeIgniter 2.1.4](http://codeigniter.org.cn/download)
  8 | * [Ucenter 1.6.0](http://www.comsenz.com/downloads/install/ucenter#down_open)
  9 | * [Discuz! X3](http://www.comsenz.com/downloads/install/discuzx)
 10 | 
 11 |   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。
 12 | 
 13 | ## 前置条件
 14 | 
 15 | - 项目目录结构如下
 16 | 
 17 |   ![image](screenshots/tree.png)
 18 | 
 19 | 
 20 | - 搭建服务器
 21 | 
 22 |   根目录指向 codeIgniter-ucenter
 23 | 
 24 |   我设置了 hosts
 25 | 
 26 |     ```
 27 |     127.0.0.1   ci.connect.uc
 28 |     ```
 29 | 
 30 |   这个任意的，这里只是为了突出主题.
 31 | 
 32 | ## 开始集成
 33 | 
 34 | - 安装 UCenter
 35 | 
 36 |   访问 http://ci.connect.uc/uc ，按照向导安装即可。
 37 | 
 38 |   ![image](screenshots/install_uc.png)
 39 | 
 40 | - 安装 DiscuzX
 41 | 
 42 |   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 UCenter 的安装信息。
 43 | 
 44 |   ![image](screenshots/install_discuz.png)
 45 | 
 46 | - 配置 CodeIgniter
 47 | 
 48 |   * 配置 application/config.php, 为使用 Session 类，需要设置 encryption_key，值任意。
 49 | 
 50 |     ```
 51 |     $config['encryption_key'] = sha1('whatever it is!');
 52 |     ```
 53 | 
 54 |   * 修改默认控制器 welcome.php 如下：
 55 | 
 56 |     ```php
 57 | 
 58 |     <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
 59 | 
 60 |         class Welcome extends CI_Controller {
 61 | 
 62 |             public function index()
 63 |             {
 64 |                 $this->load->library('session');
 65 |                 $data['user'] = $this->session->userdata('user');
 66 |                 $this->load->view('welcome_message', $data);
 67 |             }
 68 |         }
 69 | 
 70 |     ```
 71 | 
 72 |   * 修改views/welcome_message.php中的 **div#container** 如下：
 73 | 
 74 |      ```html
 75 | 
 76 |       <div id="container">
 77 |           <h1>Welcome to CodeIgniter!</h1>
 78 |           <div id="body">
 79 |               <?php if ($user): ?>
 80 |                   <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>
 81 |               <?php else: ?>
 82 |                   <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>
 83 |               <?php endif; ?>
 84 |           </div>
 85 |           <p class="footer">Page rendered in <strong>{elapsed_time}</strong> seconds</p>
 86 |       </div>
 87 | 
 88 |      ```
 89 | 
 90 |   * 在Ucenter中添加新应用
 91 | 
 92 |     看图：
 93 |     ![image](screenshots/add_new_app.png)
 94 | 
 95 |   * 在CI目录application/config/目录下新建文件ucenter.php
 96 | 
 97 |     内容为Ucenter为新加应用生成的配置文件
 98 | 
 99 |     ```php
100 | 
101 |     <?php
102 |         define('UC_CONNECT', 'mysql');
103 |         define('UC_DBHOST', 'localhost');
104 |         define('UC_DBUSER', 'root');
105 |         define('UC_DBPW', 'root');
106 |         define('UC_DBNAME', 'ucenter');
107 |         define('UC_DBCHARSET', 'utf8');
108 |         define('UC_DBTABLEPRE', '`ucenter`.uc_');
109 |         define('UC_DBCONNECT', '0');
110 |         define('UC_KEY', 'whatever you wanna set!');
111 |         define('UC_API', 'http://ci.connect.uc/uc');
112 |         define('UC_CHARSET', 'utf-8');
113 |         define('UC_IP', '');
114 |         define('UC_APPID', '2');
115 |         define('UC_PPP', '20');
116 | 
117 |     ```
118 | 
119 |     * 从uc安装包中复制uc_client到ci根目录
120 | 
121 |     * 新增控制器api/uc.php
122 | 
123 |       内容如下：
124 | 
125 |       ```php
126 | 
127 |       <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
128 |   
129 |       /**
130 |        *  Ucenter接口通知处理控制器
131 |        *
132 |        *  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。
133 |        *  具体请仔细阅读ucenter自带的手册。
