Sharetronix代码分析_随笔01

1. 所有连接请求都经过根目录里的.htaccess处理了url rewrite
    

   <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?%{QUERY_STRING} [NE,L]
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
   IfModule>

2. 现在所有请求都发送给index.php作为参数
3. index.php仅加载 ./system/LOADER.php
4. LOADER.php
   

   $SCRIPT_START_TIME  = microtime(TRUE);
   //microtime() 函数返回当前 Unix 时间戳和微秒数。
   //如果给出了 get_as_float 参数并且其值等价于 TRUE，该函数将返回一个浮点数。
   chdir(dirname(__FILE__));
   //切换路径到当前文件所属路径： ./system/
   require_once('./helpers/func_main.php');
   //调用库函数，func_main.php的第一个__autoload方法会自动加载system/class/目录下的所有类
   require_once('./conf_system.php');
   //调用配置参数，主要是会引用conf_main.php，一个安装后生成的配置文件，有数据库信息
   session_start();   //开启php session机制
   $cache  = new cache();   //创建一个system/classes/class_cache.php类的实例
   $db1 = new mysql($C->DB_HOST, $C->DB_USER, $C->DB_PASS, $C->DB_NAME);
   $db2 = &$db1;
   if( ! $C->INSTALLED ) {   //conf_main.php里定义的
       exit;
   }
   $network    = new network();   //class_network.php
   $network->LOAD();
   $user       = new user();   //class_user.php
   $user->LOAD();
   ob_start('ob_gzhandler', 6);   //缓存输出，callback调用ob_gzhandler
   $page       = new page();
   $page->LOAD();

5. conf_main.php
    

   
   $C->DOMAIN      = 'localhost';
   $C->SITE_URL    = 'http://localhost/';
   // Random identifier for this installation on this server
   $C->RNDKEY  = '15009';
   $C->DB_HOST = 'localhost';
   $C->DB_USER = 'root';
   $C->DB_PASS = '123456';
   $C->DB_NAME = 'db_name';
   $C->DB_MYEXT = 'mysqli'; // 'mysqli' or 'mysql'
   // CACHE SETTINGS
   $C->CACHE_MECHANISM = 'filesystem'; // 'apc' or 'memcached' or 'mysqlheap' or 'filesystem'
   $C->CACHE_EXPIRE        = 3600;
   $C->CACHE_KEYS_PREFIX   = '15009';
   // If 'memcached':
   $C->CACHE_MEMCACHE_HOST = '';
   $C->CACHE_MEMCACHE_PORT = '';
   // If 'filesystem':
   $C->CACHE_FILESYSTEM_PATH   = $C->INCPATH.'cache/';
   // IMAGE MANIPULATION SETTINGS
   $C->IMAGE_MANIPULATION  = 'gd'; // 'p_w_picpathmagick_cli' or 'gd'
   // if 'p_w_picpathmagick_cli' - /path/to/convert
   $C->IM_CONVERT  = 'convert';
   // DEFAULT LANGUAGE
   $C->LANGUAGE    = 'en';
   // USERS ACCOUNTS SETTINGS
   // if urls are user.site.com or site.com/user
   // this setting is still beta and it is not working properly
   $C->USERS_ARE_SUBDOMAINS    = FALSE;
   // RPC PING SETTINGS
   $C->RPC_PINGS_ON        = TRUE;
   $C->RPC_PINGS_SERVERS   = array('http://rpc.pingomatic.com');
   // TWITTER & FACEBOOK CONNECT SETTINGS
   // To activate Facebook Connect, check out the README.txt file
   $C->FACEBOOK_API_KEY        = '';
   // To activate Twitter OAuth login, check out the README.txt file
   $C->TWITTER_CONSUMER_KEY    = '';
   $C->TWITTER_CONSUMER_SECRET = '';
   // Bit.ly Integration - used for sharing posts to twitter
   $C->BITLY_LOGIN         = 'blogtronixmicro';
   $C->BITLY_API_KEY           = 'R_ffd756f66a4f5082e37989f1bc3301a6';
   // For inviting Yahoo contacts. Check out the README.txt file
   $C->YAHOO_CONSUMER_KEY      = '';
   $C->YAHOO_CONSUMER_SECRET   = '';
   // FOOTER "Powered by Blogtronix" BACKLINK
   // The License requires you to keep this backlink. To remove it, visit this page
   // and follow the instructions: http://sharetronix.com/sharetronix/linkremoval
   // Otherwise you are not allowed to modify this variable or remove the link.
   $C->FOOTER_REMOVE_BACKLINK  = FALSE;
   // IF YOUR SERVER SUPPORTS CRONJOBS, READ THE FILE ./system/cronjobs/readme.txt
   $C->CRONJOB_IS_INSTALLED    = FALSE;
   // DO NOT REMOVE THIS
   $C->INSTALLED   = TRUE;
   $C->VERSION     = '1.5.4';
   $C->DEBUG_USERS     = array();
   ?>

6. 还没看到怎么调用控制器的，继续查代码
    (page类里的_parse_input()方法貌似是处理url字符，做路由选择控制器的)
    (load_template()方法应该是调用视图的 )
7. 预留
