功能描述 / Feature Description from langchain.memory.chat_memory import BaseChatMemory 改行源码在哪里,是如何实现上下文记忆的?
The text was updated successfully, but these errors were encountered:
BaseChatMemory 实现上下文记忆的方式主要体现在 ConversationBufferDBMemory 类中。它通过以下方法管理和检索对话历史:
BaseChatMemory
ConversationBufferDBMemory
存储消息:BaseChatMemory 本身不直接存储消息,而是通过 filter_message 函数从数据库中检索消息。message_limit 属性决定了检索的最大消息数量。
filter_message
message_limit
检索消息:buffer 属性负责从数据库中按时间倒序获取消息,然后将其顺序反转以保持时间顺序。它将这些消息构造成 HumanMessage 和 AIMessage 对象列表,代表对话历史。
buffer
HumanMessage
AIMessage
修剪消息:如果缓冲区中的令牌总数超过 max_token_limit,则会修剪最旧的消息,直到令牌数在限制范围内。这通过迭代地从列表开始移除消息来实现。
max_token_limit
返回历史:load_memory_variables 方法根据 return_messages 标志返回对话历史,格式可以是字符串或消息列表。历史记录使用 human_prefix 和 ai_prefix 来区分人类和 AI 消息。
load_memory_variables
return_messages
human_prefix
ai_prefix
这些方法确保系统能够动态检索和管理对话历史,从而保持对话上下文的记忆 [1][2][3]。

ConversationBufferDBMemory类是在整个项目的哪个环节被调用的,上下文记忆的逻辑处理是按照什么样的形式调用?
ConversationBufferDBMemory 类在项目中的 libs/chatchat-server/chatchat/server/memory/conversation_db_buffer_memory.py 部分被调用。上下文记忆的逻辑处理通过 buffer 属性来调用,该属性从数据库中检索并处理对话历史。它使用 conversation_id 定位特定对话,并将消息格式化为 HumanMessage 和 AIMessage 对象列表。load_memory_variables 方法进一步处理此缓冲区,以返回适合生成响应的对话历史格式。此外,该类包含修剪聊天消息的逻辑,以确保对话历史保持在可管理的范围内 [1][2][3]。
