Your Question

I have built a knowledge base that works normally in conversation mode, but I want to use Python to call it through API. However, only the basic dialogue function of the LLM is available, and the knowledge base cannot be used. The prompt word examples given in api-doc do not have the relevant usage of knowledge_base, so I am seeking help from everyone.

Here is my Payload example:

BASE_URL = "http://127.0.0.1:9000/v1/chat/completions"

HEADERS = {
    "accept": "application/json",
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

PAYLOAD=
    {
      "model": "dashscope:qwen3.5-plus",
       "messages": [
            {"role": "system", "content": "【 System Instructions 】 Answer strictly according to the content of the knowledge base and prohibit free expression. If there is no relevant answer in the knowledge base, a response must be given stating 'unable to answer based on existing information''"},
            {"role": "user", "content": "What are the functions of the big data analysis module for social governance in the government industry?"}
        ],
      "temperature": 1,
      "knowledgebase": "KB-Test",
      "max_tokens": 1,
      "stream": false  
    }

I have tried "knowledgebase","knowledgeBase","knowledge-base","KB" and "knowledge_base" in payload, but none of them work. :<

Thank you!
