RunnableWithMessageHistory 是一个包装器,可以让链自动处理历史消息的填充和存储过程。 以下是一个使用 RunnableWithMessageHistory 的示例: importdotenvfromlangchain_community.chat_message_historiesimportFileChatMessageHistoryfromlangchain_core.chat_historyimportBaseChatMessageHistoryfromlangchain_core.output_parsersimpo...
具体来说,RunnableWithMessageHistory在将消息传递给Runnable之前加载会话中以前的消息,并在调用Runnable之后将生成的响应保存为消息。RunnableWithMessageHistory还通过用session_id保存每个会话来实现启用多个会话,因此它希望在调用Runnable时在配置中传递session_id,并使用它来查找相关的会话历史记录。 在第五期 LangChain学习...

Feedback that RunnableWithMessageHistory is unwieldy compared to ConversationChain and similar legacy abstractions is common. Legacy chains using memory typically had no explicit notion of threads or separate sessions. To use RunnableWithMessageHistory,
console.log(`Finished with result: ${data.result}`); } (error: unknown) { console.error(`Error occurred: ${(error as Error).message}`); } //自定义执行逻辑 async invoke(name: string): Promise<string> { this.onStart({ input: name }); ...
{...to, replace: true}) // hack方法 确保addRoutes已完成 ,set the replace: true so the navigation will not leave a history record }) }) .catch(() => { store.dispatch('FedLogOut').then(() => { Message.error('验证失败, 请重新登录') next({path: '/login'}) }) }) } else ...
