有没有开放的知识库url，可以用代码通过接口或者其他方式把存放在存储中的文件放入知识库而不是人工通过maxkb界面上传？
整了一上午整明白了
将文档通过接口形式放入知识库分为两部分：
* 1.获取身份识别码
* 2.将文件分段并拿到分段值
* 3.将分段值传入知识库上传文档接口，完成上传操作
第一步需要获取身份识别码，没有这个码在上传的时候会被身份验证卡住报401
第二步里需要将文档通过接口分段 通过接口的返回值获取到分段后的数据
第三步将分段后的数据传入报错接口
以下是java代码

import org.json.JSONObject;
import com.fasterxml.jackson.databind.ObjectMapper;

想问下您这个通过java调用api接口的方式社区版可以实现吗，还是要付费版
开放API是企业版支持的功能~
