LangGraph平台线程与助手工作异常技术问询

核心异常现象 #

• 线程消息串扰：创建两个独立线程Thread1、Thread2后，查询Thread2时返回的消息列表包含Thread1的消息内容
• Config线程ID不一致：查询线程返回的config对象中，thread_id字段值与创建线程时指定的ID完全不同，但指定的线程ID可正常被查询（证明线程已成功创建）

操作流程 #

1. 创建关联图的Assistant
2. 启动Thread1对话
3. 启动Thread2对话
4. 查询Thread2时发现消息串扰问题

命令与对象示例 #

启动Thread1 #

POST http://localhost:2024/threads/73db4e56-58b1-4b62-ad2d-bdd37bda4c4a/runs/wait

发送的Config对象：

Configuration(
recursion_limit=1000,
deployment_url='http://localhost:2024',
user_id='user_123456',
stories_category='general',
personality_role="You are a mischievious Discord bot. You are not lame or uncool or annoying. \nYou try to speak back in the same style as the user.\nYou are succinct and don't ramble.\n",
graph_name='analyst_create_analysts',
thread_id='73db4e56-58b1-4b62-ad2d-bdd37bda4c4a'
)

启动Thread2 #

POST http://localhost:2024/threads/2457e3c3-c626-4866-8a93-38b5de849098/runs/wait

发送的Config对象：

Configuration(
recursion_limit=1000,
deployment_url='http://localhost:2024',
user_id='user_123456',
stories_category='general',
personality_role="You are a mischievious Discord bot. You are not lame or uncool or annoying. \nYou try to speak back in the same style as the user.\nYou are succinct and don't ramble.\n",
graph_name='analyst_create_analysts',
thread_id='2457e3c3-c626-4866-8a93-38b5de849098'
)

参考文档（翻译版） #

LangGraph API参考：线程运行流接口，用于启动指定线程的运行并以流形式返回结果。接口路径为POST /threads/{thread_id}/runs/stream，其中{thread_id}为目标线程的ID。该接口触发与助手关联的图执行，执行过程中的输出会以流的形式返回，同时更新线程的状态和对话历史。
