项目发现ECmobile的应用首页的特价区只显示1个商品和分类区只显示2个商品，需要按要求显示
于是查找了接口文件/Controller/Home/Data.php
发现代码 function gz_get_promote_goods($cats = ”)中的如下代码
/* 取得促销lbi的数量限制 */
$num = get_library_number(“recommend_promotion”);
那么recommend_promotion在哪设置的？
于是又去找函数位置get_library_number（）在哪
发现在\includes\lib_main.php中
代码如下：
<span class="pln"></span><span class="com">/*** 取得某模板某库设置的数量* @param string $template 模板名，如index* @param string $library 库名，如recommend_best* @param int $def_num 默认数量：如果没有设置模板，显示的数量* @return int

发现，它是在ecs_template中设置的，那么就简单了，就到数据库查询设置的显示数量，修改了即可了，开源没有文档真的很坑爹，
