利用微擎開發些微信公眾號還是非常方便的；模組機制分析主要從其安裝、解除安裝、使用角度，

 

一、安裝

安裝介面，主要是module_get_all_unistalled獲取未安裝模組

 

1.   if ($do == 'not_installed') {
2.   if (empty($_W['isfounder'])) {
3.   itoast( '非法訪問！', referer(), 'info');
4.   }
5.   $_W[ 'page']['title'] = '安裝模組 - 模組 - 擴充套件';
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 函式原始碼，可以看到先判斷是否有快取（微擎的快取實現機制還是很清晰易懂的，資料庫、檔案、memcache、Redis），沒有再取，關鍵是cache_build_uninstalled_module；可以看到有云模組的請求，當然這部分你可以幹掉，我還是堅持用正版哈

 

 

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原始碼，現在知道為什麼模組要放在addons下了，最後還把模組資訊寫入快取，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');

15.   $recycle_modules = pdo_getall( 'modules_recycle', array(), array(), 'modulename');
16.   $recycle_modules = array_keys($recycle_modules);
17.   $cloud_module = cloud_m_query();
18.    
19.   if (!empty($cloud_module) && !is_error($cloud_module)) {
20.   foreach ($cloud_module as $module) {

還有個地方值得學習，模組的資訊定義在manifest.xml中，有點java的感覺，具體資訊讀取都在extension.mod.php中，程式碼如下

 

 

 

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.   $manifest[ 'versions'][] = '0.52';
24.   $manifest[ 'versions'][] = '
