Power BI Excel Power Query怎么调用DeepSeek?

(question as text) as text =>
let
    apiKey = "你申请的DeepSeekKey",
    baseUrl = "https://api.deepseek.com/v1/chat/completions/",
    requestBody = Json.FromValue([
        model = "deepseek-chat",
        messages = {
            [role = "system", content = "你是一个助手，回答用户的问题。"],
            [role = "user", content = question]
        }
    ]),
    headers = [
        #"Content-Type" = "application/json",
        #"Authorization" = "Bearer " & apiKey
    ],
    response = Web.Contents(baseUrl, [
        Headers = headers,
        Content = requestBody
    ]),
    jsonResponse = Json.Document(response),
    answer = jsonResponse[choices]{0}[message][content]
in
    answer

messages = {
            [role = "system", content = "你是一个语言大师，将用户的内容翻译为英文。"],
            [role = "user", content = question]
}
