最近更新时间：2025-11-27 20:56:33

非流式请求及返回内容

当您未对stream参数进行设置时，模型默认为非流式返回。

request

curl -X POST https://kspmas.ksyun.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $KSC_API-KEY" \
  -d '{
        "model": "deepseek-v3.1",
        "messages": [
            {
            "role": "user",
            "content": "你好"
            }
        ],
    }'

  }
}

流式请求及返回内容

当您需要模型进行流式返回内容时，将stream参数的值设定为true即可。

request

curl -X POST https://kspmas.ksyun.com/v1/chat/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer {API-KEY}" \
  -d '{
        "model": "deepseek-v3.1",
        "messages": [
            {
            "role": "user",
            "content": "nihao"
            }
        ],
        "stream": true
    }'
