chatchat已经部署好了,请问如何实现我调知识库,通过几行代码传入“问题”,chatchat直接返回检索的top3文档?

请问如何实现这一过程,现在只有web界面,我想把chatchat返回的内容作为我另一个需求的输入。@dosu-bot

要通过代码从 chatchat 检索并返回 top3 文档,可以使用 kb_chat 函数,并设置 top_k 参数为 3。以下是一个示例代码片段,展示如何实现这一过程:

from fastapi import Body

# 假设你已经设置了其他必要的参数
query = "你的查询内容"
kb_name = "你的知识库名称"

# 调用 kb_chat 函数,设置 top_k 为 3
response = await kb_chat(
    query=Body(query),
    mode=Body("local_kb"),
    kb_name=Body(kb_name),
    top_k=Body(3),  # 设置为3以返回top3文档
    score_threshold=Body(0.5),  # 可根据需要调整
    return_direct=Body(True)  # 直接返回检索结果
)

# 处理返回的文档
for doc in response:
    print(doc)

在这个代码片段中,top_k 参数被设置为 3,以确保返回的文档数量为 top3。return_direct 参数被设置为 True,以便直接返回检索结果而不经过 LLM 处理[1].
