教程: CodeIgniter 整合 UCenter 全攻略

2015-03-31 11:46 来源:codeigniter.org.cn 编辑:admin

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

    image

  • 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:
    <?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);
            }
        }
    
    
    • 修改 views/welcome_message.php 中的 div#container 如下:

      <div id="container">
        <h1>Welcome to CodeIgniter!</h1>
        <div id="body">
            <?php if ($user): ?>
                <p>欢迎你, <?php echo $user['username']; ?><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>
      
      
    • 在 UCenter 中添加新应用

    看图:image

    • 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
        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');
    
    
    • 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:

      <?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。
      *
