## Feed knowledge
|
|
|
|
Use the feed knowledge interface to feed knowledge into the database. Before that, you need to create an Agent to manage the Chatbot, and the Agent's `id` is needed in subsequent operations.
|
|
`http://localhost:5500/knowledge/{agentId}`, You can add `startPageNum` and `endPageNum` to select useful parts of the document.
