实现了如下功能（使用react实现，原创）
实现功能：
1、对接gpt35模型问答，并实现了流式传输（在java端）
2、在实际使用中，我们的问答历史会经常分享给他人，所以下图的 copy all 按钮，可以copy成一个json然后通过社交软件发送给别人，别人就可以轻松应用你的问答历史。
3、选择文件，在我们预想当中，我们可能会经常遇到向文档提问（当时还不知道embedding的知识哈哈哈），通过拆分文档，一段段跟gpt提问，当前段落是否和用户内容相关，相关就回答段落问题（段落拆分通过java实现）
4、我们需要经常保存我们的聊天记录，特别是在调试我们的prompt的时候，所以加了一个缓存功能，可以随时提取缓存记录来提问。
5、利用这个分享的时候，设计了很多便利我去学习英语的prompt,避免老是手打提示词
role.js
