标题: fastadmin中对CDN的逻辑梳理
CDN的全称是Content Delivery Network，CDN 指的是内容分发网络

app/config.php中
// 视图输出字符串内容替换,留空则会自动进行计算
'view_replace_str'    => [
      '__PUBLIC__' => '',
      '__ROOT__' => '',
      '__CDN__' => '/dba',
],

以首页帐号图标的显示入手分析:1、原代码
<div class="pull-left image">
<a href="general/profile" class="addtabsit"><img src="{$admin.avatar|cdnurl|htmlentities}" class="img-circle" /></a>
</div>

2、解析后的代码
<img class="profile-user-img img-responsive img-circle" src="<?php echo htmlentities(cdnurl($admin['avatar'] ?? '') ?? ''); ?>" alt="">

3、找到代码
>>>>c:\apache24\htdocs\application50\common.php<<<<<
function cdnurl($url, $domain = false)

结论：
thinkphp/library/think/App.php

//1. 加载模块配置
         $config = Config::load(CONF_PATH . $module . 'config' . CONF_EXT);

//2. 读取数据库配置文件
         $filename = CONF_PATH . $module . 'database' . CONF_EXT;
         Config::load($filename, 'database');

//3. 读取扩展配置文件
         if (is_dir(CONF_PATH . $module . 'extra')) {
            $dir = CONF_PATH . $module . 'extra';
            $files = scandir($dir);
            foreach ($files as $file) {
                  if ('.' . pathinfo($file, PATHINFO_EXTENSION) === CONF_EXT) {
                     $filename = $dir . DS . $file;
                     Config::load($filename, pathinfo($file, PATHINFO_FILENAME));
                  }
            }
         }

//3. 加载应用状态配置
         if ($config['app_status']) {
            Config::load(CONF_PATH . $module . $config['app_status'] . CONF_EXT);
         }
