博客系统-3.0CodeIgniter系统SAE版本的配置 application/config/

1. autoload.php(系统启动时自动加载的文件：包，类库，驱动，方法助手，配置)
1. $autoload['libraries'] = array('database', 'access', 'pagination');//类库：数据库/权限类/分页类
2. $autoload['drivers'] = array('session');//驱动：session
3. $autoload['helper'] = array('url', 'file', 'cookie', 'form', 'array');//方法：url，文件，cookie，表单，数组
4. $autoload['config'] = array('app');//配置：项目
2. config.php 项目公共配置
1. $config['enable_hooks'] = TRUE;//使用钩子
2. $config['log_threshold'] = 0;//日志记录级别
3. $config['log_path'] = '';//日志路径
4. $config['cache_path'] = '';//缓存路径
5. $config['encryption_key'] = 'blog_;//session加密
6. $config['sess_expiration']        = 3600;//session过期时间
7. $config['sae_output_cache'] = 'kvdb';//输出类页面缓存配置
3. constants.php 静态变量
1. define('PAGE_LIMIT', 10);//每页条数
4. database.php 数据库，判断是否SAE环境，调用不同配置
1. 判断是否是SAE环境

   if ( ! function_exists('is_sae'))
   {
       /**
        * 检查是否是SAE环境
        *
        * @return    bool  TRUE 代表是SAE
        */
       function is_sae()
       {
           return function_exists('sae_debug');
       }
   }

//根据环境选择数据库配置
$query_builder = TRUE;
if (is_sae()) {
    $active_group = 'sae';
    $db['sae'] = array(
        'dsn'    => '',
        'hostname' => SAE_MYSQL_HOST_M,
        'hostname_s' => SAE_MYSQL_HOST_S,

        'dbdriver' => 'mysqli',
        'dbprefix' => '',
        'pconnect' => FALSE,
        'db_debug' => TRUE,
        'cache_on' => FALSE,
        'cachedir' => '',//SAE数据库缓存, 使用kvdb进行缓存. 此配置值为key前缀, 例如 "dbcache_". 若不设置, 则不缓存
        'char_set' => 'utf8',
        'dbcollat' => 'utf8_general_ci',
        'swap_pre' => '',
        'autoinit' => TRUE,
        'encrypt' => FALSE,
        'compress' => FALSE,
        'stricton' => FALSE,
        'failover' => array(),
        'save_queries' => TRUE
    );
}
else {
    $active_group = 'local';
    $db['local'] = array(
        'dsn'    => '',
        'hostname' => '127.0.0.1',
        'username' => 'root',
        'password' => 'root',
        'database' => 'blog',
        'port' => '3306',
        'dbdriver' => 'mysqli',
        'dbprefix' => '',
        'pconnect' => FALSE,
        'db_debug' => TRUE,
        'cache_on' => FALSE,
        'cachedir' => '',
        'char_set' => 'utf8',
        'dbcollat' => 'utf8_general_ci',
        'swap_pre' => '',
        'autoinit' => TRUE,
        'encrypt' => FALSE,
        'compress' => FALSE,
        'stricton' => FALSE,
        'failover' => array(),
        'save_queries' => TRUE
    );
}

1. routes.php 默认路由

$route['default_controller'] = 'site';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
