数据处理所有算子对 meta文件夹的免干扰： doc转 md ， md 分支转json , 然后 json 数据转换，去替换手机号, 手机号替换报错

[zanguixuan3]

doc转 md , md 分支转json ,然后 json 去替换手机号。 md转 json 的结果记录 影响后续算子计算的转化。
客户想要流畅丝滑的操作体验。不想手动去删除 meta文件夹。

报错如下：

在下面这两个功能里加个j是否生成meta选项吧，默认不生成meta文件夹及meta.json文件，只有选中再生成。这样就不会出现影响数据处理的流程了meta文件夹了。

1. 数据采集格式转换功能
2. md2json tool功能

改个文件名叫meta/meta.log, 在页面上加个是 否生成meta选项，默认不要选中。
