打开https://xinghuo.xfyun.cn/sparkapi，往下滑找到spark lite，目前免费开放的是spark lite，点击立即体验

跳转到控制台，需要登录然后创建一个应用，我这里已经创建好

点进去应用，可以看到详情，这里可以测试对话

点击左侧的spark lite，可以看到有无限量的token，右侧有访问API是需要用到的key

不同的平台有不同的访问方式

这里我们详细说一下怎么通过HTTP的方式进行调用：

请求地址

https://spark-api-open.xf-yun.com/v1/chat/completions

请求头：

Content-Type: application/json
Authorization: Bearer YOUR_APIPassword

一个完整的请求：

curl -i -k -X POST 'https://spark-api-open.xf-yun.com/v1/chat/completions' \
--header 'Authorization: Bearer YOUR_APIPassword' \
--header 'Content-Type: application/json' \
--data '{
    "model":"lite",
    "messages": [
        {
            "role": "user",
            "content": "来一个只有程序员能听懂的笑话"
        }
    ],
    "stream": true
}'

请求参数：

错误时的响应参数：

{
    "error": {
        "message": "invalid user",
        "type": "api_error",
        "param": null,
        "code": null
    }
}

非流式的响应参数：

{
    "code": 0,
    "message": "Success",
    "sid": "cha000b0003@dx1905cd86d6bb86d552",
    "choices": [
        {
            "message": {
                "role": "assistant",
                "content": "你好，我是由科大讯飞构建的星火认知智能模型。\n如果你有任何问题或者需要帮助的地方，请随时告诉我！我会尽力为你提供解答和支持。请问有什么可以帮到你的吗？"
            },
            "index": 0
        }
    ],
    "usage": {
        "prompt_tokens": 6,
        "completion_tokens": 42,
        "total_tokens": 48
    }
}

流式请求成功时的响应格式：
