利用微擎开发些微信公众号还是非常方便的；模块机制分析主要从其安装、卸载、使用角度，

一、安装

安装界面，主要是module_get_all_unistalled获取未安装模块

1.  
   if ($do == 'not_installed') {
2.  
   if (empty($_W['isfounder'])) {
3.  
   itoast('非法访问！', referer(), 'info');
4.  
   }
5.  
   $_W['page']['title'] = '安装模块 - 模块 - 扩展';
6.  
    
7.  
   $status = $_GPC['status'] == 'recycle'? 'recycle' : 'uninstalled';
8.  
   $letters = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
9.  
   $title = $_GPC['title'];
10.  
    $letter = $_GPC['letter'];
11.  
    $pageindex = max($_GPC['page'], 1);
12.  
    $pagesize = 20;
13.  
     
14.  
    $uninstallModules = module_get_all_unistalled($status, false);
15.  
    $total_uninstalled = $uninstallModules['module_count'];
16.  
    $uninstallModules = (array)$uninstallModules['modules'];
17.  
    if (!empty($uninstallModules)) {
18.  
    foreach($uninstallModules as $name => &$module) {
19.  
    if (!empty($letter) && strlen($letter) == 1) {
20.  
    $first_char = get_first_pinyin($module['title']);
21.  
    if ($letter != $first_char) {
22.  
    unset($uninstallModules[$name]);
23.  
    continue;
24.  
    }
25.  
    }
26.  
    if (!empty($title)) {
27.  
    if (!strexists($module['title'], $title)) {
28.  
    unset($uninstallModules[$name]);
29.  
    continue;
30.  
    }
31.  
    }
32.  
     
33.  
    if (file_exists(IA_ROOT.'/addons/'.$module['name'].'/icon-custom.jpg')) {
34.  
    $module['logo'] = tomedia(IA_ROOT.'/addons/'.$module['name'].'/icon-custom.jpg');
35.  
    } elseif (file_exists(IA_ROOT.'/addons/'.$module['name'].'/icon.jpg')) {
36.  
    $module['logo'] = tomedia(IA_ROOT.'/addons/'.$module['name'].'/icon.jpg');
37.  
    } else {
38.  
    $module['logo'] = tomedia($module['thumb']);
39.  
    }
40.  
    if (!empty($module['main_module'])) {
41.  
    $main_module_installed = module_fetch($module['main_module']);
42.  
    if ($main_module_installed) {
43.  
    $module['main_module_logo'] = $main_module_installed['logo'];
44.  
    } else {
45.  
    if ($module['from'] == 'cloud') {
46.  
    $module['main_module_logo'] = tomedia($uninstallModules[$module['main_module']]['thumb']);
47.  
    } else {
48.  
    if (file_exists(IA_ROOT.'/addons/'.$module['main_module'].'/icon-custom.jpg')) {
49.  
    $module['main_module_logo'] = tomedia(IA_ROOT.'/addons/'.$module['main_module'].'/icon-custom.jpg');
50.  
    } elseif (file_exists(IA_ROOT.'/addons/'.$module['main_module'].'/icon.jpg')) {
51.  
    $module['main_module_logo'] = tomedia(IA_ROOT.'/addons/'.$module['main_module'].'/icon.jpg');
52.  
    }
53.  
    }
54.  
    }
55.  
    }
56.  
    }
57.  
    }
58.  
    $total = count($uninstallModules);
59.  
    $uninstallModules = array_slice($uninstallModules, ($pageindex - 1)*$pagesize, $pagesize);
60.  
    $pager = pagination($total, $pageindex, $pagesize);
61.  
    }

module_get_all_unistalled 函数源码，可以看到先判断是否有缓存（微擎的缓存实现机制还是很清晰易懂的，数据库、文件、memcache、Redis），没有再取，关键是cache_build_uninstalled_module；可以看到有云模块的请求，当然这部分你可以干掉，我还是坚持用正版哈

1.  
   function module_get_all_unistalled($status, $cache = true) {
2.  
   global $_GPC;
3.  
   load()->func('communication');
4.  
   load()->model('cloud');
5.  
   load()->classs('cloudapi');
6.  
   $status = $status == 'recycle' ? 'recycle' : 'uninstalled';
7.  
    
8.  
    
9.  
    
10.  
    $uninstallModules = cache_load(cache_system_key('module:all_uninstall'));
11.  
     
12.  
    if (!$cache && $status == 'uninstalled') {
13.  
    $cloud_api = new CloudApi();
14.  
    $get_cloud_m_count = $cloud_api->get('site', 'stat', array('module_quantity' => 1), 'json');
15.  
    $cloud_m_count = $get_cloud_m_count['module_quantity'];
16.  
    } else {
17.  
     
18.  
    if(is_array($uninstallModules)){
19.  
    $cloud_m_count = $uninstallModules['cloud_m_count'];
20.  
    }
21.  
    }
22.  
    if (empty($uninstallModules['modules']) || intval($uninstallModules['cloud_m_count']) !== intval($cloud_m_count) || is_error($get_cloud_m_count)) {
23.  
     
24.  
    $uninstallModules = cache_build_uninstalled_module();
25.  
    }
26.  
    if (ACCOUNT_TYPE == ACCOUNT_TYPE_APP_NORMAL) {
27.  
    $uninstallModules['modules'] = (array)$uninstallModules['modules'][$status]['wxapp'];
28.  
    $uninstallModules['module_count'] = $uninstallModules['wxapp_count'];
29.  
    return $uninstallModules;
30.  
    } elseif (ACCOUNT_TYPE == ACCOUNT_TYPE_OFFCIAL_NORMAL) {
31.  
    $uninstallModules['modules'] = (array)$uninstallModules['modules'][$status]['app'];
32.  
    $uninstallModules['module_count'] = $uninstallModules['app_count'];
33.  
    return $uninstallModules;
34.  
    } else {
35.  
    return $uninstallModules;
36.  
    }
37.  
    }

cache_build_uninstalled_module源码，现在知道为什么模块要放在addons下了，最后还把模块信息写入缓存，以便下次直接使用

1.  
   function cache_build_uninstalled_module() {
2.  
   load()->model('cloud');
3.  
   load()->classs('cloudapi');
4.  
   load()->model('extension');
5.  
   load()->func('file');
6.  
   $cloud_api = new CloudApi();

8.  
   $cloud_m_count = $cloud_api->get('site', 'stat', array('module_quantity' => 1), 'json');

12.

14.  
    $uninstallModules = array('recycle' => array(), 'uninstalled' => array());
15.  
    $recycle_modules = pdo_getall('modules_recycle', array(), array(), 'modulename');
16.  
    $recycle_modules = array_keys($recycle_modules);
17.  
    $cloud_module = cloud_m_query();
18.  
     
19.

24.

还有个地方值得学习，模块的信息定义在manifest.xml中，有点java的感觉，具体信息读取都在extension.mod.php中，代码如下

1.  
   function ext_module_manifest_parse($xml) {
2.  
   if (!strexists($xml, '<manifest')) {
3.  
   $xml = base64_decode($xml);
4.  
   }
5.  
   if (empty($xml)) {
6.  
   return array();
7.  
   }
8.  
   $dom = new DOMDocument();
9.  
   $dom->loadXML($xml);
10.  
    $root = $dom->getElementsByTagName('manifest')->item(0);
11.  
    if (empty($root)) {
12.  
    return array();
13.  
    }
14.  
    $vcode = explode(',', $root->getAttribute('versionCode'));
15.  
    $manifest['versions'] = array();
16.  
    if (is_array($vcode)) {
17.  
    foreach ($vcode as $v) {
18.  
    $v = trim($v);
19.  
    if (!empty($v)) {
20.  
    $manifest['versions'][] = $v;
21.  
    }
22.  
    }
23.

24.
