 * 建议：
 * 传参 ?type=url&params=../json/采集静态.json$1
 * 传参 ?type=url&params=../json/采集[zy]静态.json$1
 * 传参 ?type=url&params=../json/采集[密]静态.json$1
 * hipy-server支持@改名比如:

    update_info: `
20240706:
1.静态json数据支持cate_excludes分类名称列表过滤无数据分类
2.更新采集分类生成器增加过滤筛选模式
20240705:
1.支持传参json后面增加$1 这样的额外标识，用于搜索结果精准匹配
2.支持传参json后面增加$1$1 这样的额外标识，用于强制获取搜索图片。$1$不显示图片。默认是搜索强制有图片的[已实现详情页请求使用批量]
3.修复二级数据无序匹配搜索列表图片的问题
4.修改搜索精准和图片显示额外参数间隔符从#变为$
20240703:
1.采集json支持"searchable": 0,用于搜索时排除这个源
20240604:
1.首页推荐取消硬控等待。增加随机推荐功能。
2.首页推荐新增更新日志查看功能
【特别说明】目前只支持标准json格式的采集站(资源站一般都提供xml和json两种接口，目前没有支持xml的想法，没什么必要)
有些资源站的json接口不是标准的/api.php/provide/vod/,需要自己在采集静态.json中编辑对应的api属性填写比如:/api.php/provide/vod/at/json/
有些资源站的采集数据是加密后的切片片段，可能需要采集站特定的解析接口，需要自己编辑json里的parse_url属性
资源站部分大分类下无数据很正常，可以自行编辑json里cate_exclude属性排除掉自己测试过无数据的分类(小程序无法自动识别，只能人工测好哪些分类无数据)
