淘宝无货源运营流程 3.1 上架 - 下载淘宝天猫详情页数据包、图片、视频到同一目录
访问电商记网站（ dianshangji.com ）安装电商记插件和流程管理系统可使用本功能。 点击文章底部 [ 阅读原文 ] 链接可查看插件安装说明。
学习步骤
本教程将整套淘宝无货源经营流程分解为一百多个任务节点，其中大部分节点均为自动运行的网页流程，可使用电商记插件进行开发，其余节点则是需要人工操作的步骤。任务内容从选词选品、到发布宝贝、处理差异化、到下单发货等环节全有涉及，用户按照序号进行逐个学习和开发即可。开发过程其实很简单，分3个基础阶段：
-
选词
-
选品
-
上架
上架 - 下载淘宝天猫详情页数据包、图片、视频到同一目录
流程管理系统基于流程8384采集淘宝或天猫详情页上的标题、价格、主图、视频、SKU列表、商品属性、详情描述等各种信息（参看《采集天猫详情页数据包使用说明》），以宝贝ID为目录名，将数据包存为本地json文件（data/taobaoitemdetail.json），从数据包中提取图片链接和视频链接，将所有对应的网络内容下载到以宝贝ID命名的目录中。
用户需将指定的一组宝贝ID输入到流程图中。双击“注入”节点，编辑“msg.payload”字段：
在图示的“宝贝ID”数组中，逐个添加一组宝贝ID：
流程图的配置内容如下所示，用户可复制后导入到自己的流程管理系统。
