Steps to reproduce

请问通过API 访问/chat-messages 接口如何增加上下文知识库和前置一些数据信息RAG，在文档中只看到了访问对话，没有说怎么增加上下文知识库参数

{"inputs":{"maxTokens":0,"temperature":0.0},"query":"报销金额","response_mode":"streaming","conversation_id":"","user":"app_id","files":[{"type":"knowledge_base","transfer_method":"file_id","file_id":"af898965-7372-4553-a4d3-183075c63f0b"}]}

Hello @284658474! 👋 I'm here to help you with any bugs, questions, or becoming a contributor. Let's squash those bugs together!

I found a similar discussion that might be relevant to your question: API 扩展能从页面传入自定义信息, which is currently unsolved [1].

Regarding your question about adding context knowledge base and RAG (Retrieval-Augmented Generation) data to the /chat-messages API, I couldn't find specific information in the available documentation. However, the inputs parameter in the API request allows you to enter various variable values defined by the app. This parameter contains key/value pairs for each variable, and if the variable is of file type, you should specify an object with the keys described in the files parameter [2][3][4].

For including additional data, the files parameter can be used to specify an array of file objects, each containing properties like type, transfer_method, and url [5].

If you need more detailed guidance on integrating RAG or context knowledge base, you might want to explore the discussions or documentation further, as the specific integration details were not found in the current sources.

To continue talking to Dosu, mention @dosu.
