想要使用文心一言，首先要登录百度智能云千帆控制台

https://cloud.baidu.com/product/wenxinworkshop?track=developer_qianfan_tanchuang

1.在控制台找到应用接入 - 然后点击创建应用

在这里插入图片描述

2.填写应用信息

在这里插入图片描述

3.创建之后，记下API Key 和 Secret Key，等会会用到

在这里插入图片描述

4.打开Unity，建一个简单的聊天场景

在这里插入图片描述

5.加入测试代码

public class ChatAI: MonoBehaviour{    public string token;    //这里填写百度千帆大模型里的应用api key    public string api_key = "xxxxxx";    //这里填写百度千帆大模型里的应用secret key    public string secret_key = "xxxxxxxxx";    //发送按钮    public Button sendBtn;    //输入框    public TMP_InputField info;    //AI回应    public TextMeshProUGUI responseText;    // 历史对话    private List<message> historyList = new List<message>();    public void Awake()    {        //初始化文心一言,获取token        StartCoroutine(GetToken());        sendBtn.onClick.AddListener(OnSend);    }       public void OnSend()    {        OnSpeak(info.text);    }    //开始对话    public void OnSpeak(string talk )    {        StartCoroutine(Request(talk));
