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

2.填写应用信息

3.创建之后，记下API Key 和 Secret Key，等会会用到

4.打开Unity，建一个简单的聊天场景

5.加入测试代码

<code>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));

}

private IEnumerator GetToken()

{

//获取token的api地址

string _token_url = string.Format("https://aip.baidubce.com/oauth/2.0/token" + "?client_id={0}&client_secret={1}&grant_type=client_credentials" , api_key, secret_key);

using (UnityWebRequest request = new UnityWebRequest(_token_url, "POST"))

{

request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();

yield return request.SendWebRequest();

if (request.isDone)

{

string msg = request.downloadHandler.text;

TokenInfo mTokenInfo = JsonUtility.FromJson<TokenInfo>(msg);

//保存Token

token = mTokenInfo.access_token;

}

}
