android集成百度文心一言实现对话功能，实战项目讲解，人人都能拥有一款ai应用

大家好，今天给大家讲解下如何实现一个基于百度文心一言的app功能，app内部同时集成了讯飞的语音识别。本文适用于有android基础的小伙伴阅读，文章末尾放上本项目用到的全部实例代码，在使用前请务必看完本文章。

先来给大家看看效果。

百度文心一言API权限申请及创建应用

第一步：打开百度文心一言的api开发者平台-千帆

百度智能云千帆大模型平台ModelBuilder

第二步：创建应用

第三步：打开android studio创建一个app

这个步骤相信大家都会，不会的就说明不适合本篇文章，可以退出阅读了。

第四步：文心一言api封装实例（从项目中提取出来的）

下面代码封装了整个文心一言的对话请求，此处用的基类，为了方便如果有不同的请求需要。

AiExample.java

/**
**封装文心一言请求
**/
public abstract class AiExample {Context mContext;static List<ChatWxyyRequestBean> chatWxyyRequestBeanList = new ArrayList<>();//用于存储文心一言的对话listpublic AiExample(Context context) {this.mContext = context;}private static final String API_URL_35 = Const.OpenAi.url35;private static final String API_URL_40 = Const.OpenAi.url40;private List<String> dialogHistory = new ArrayList<>();//定义个OkHttpClient对象static OkHttpClient client = new OkHttpClient.Builder().connectTimeout(1, TimeUnit.DAYS).readTimeout(1, TimeUnit.DAYS).callTimeout(1, TimeUnit.DAYS).build();private String context = ""; // 当前的对话上下文/*** 将当前的上下文清空,开启新对话时用到** @param chatGptExample*/public void clearContext(AiExample chatGptExample) {if (chatGptExample != null) {chatGptExample.context = "";chatWxyyRequestBeanList.clear();}}//第一次请求回调public interface FirstCallback {public void callback(String msg);}/*** 请求文心一言** @param message 请求的文字* @param tag*/public void startChatWithWxyy(String message, int tag, String API_KEY, String SECRET_KEY) {//开始第一次请求try {getAccessToken(API_KEY, SECRET_KEY, new FirstCallback() {@Overridepublic void callback(String msg) {//第一次请求成功后，获取的msg为access_tokenLog.e("tag", "文心一言的access_token=" + msg);if (!StringUtils.isBlank(msg)) {//开始进行第二次请求try {Log.e("tag", "第二次请求的messsge:" + message);requestSecond(msg, message);} catch (IOException e) {throw new RuntimeException(e);}}}});} catch (IOException e) {throw new RuntimeException(e);}}/*** 从用户的AK，SK生成鉴权签名（Access Token）** @param API_KEY* @param SECRET_KEY* @return 鉴权签名（Access Token）* @throws IOException IO异常*/public void getAccessToken(String API_KEY, String SECRET_KEY, FirstCallback firstCallback) throws IOException {final String[] access_token = {""};MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");RequestBody body = RequestBody.create("grant_type=client_credentials&client_id=" + API_KEY+ "&client_secret=" + SECRET_KEY, mediaType);Request request = new Request.Builder().url("https://aip.baidubce.com/oauth/2.0/token").method("POST", body).addHeader("Content-Type", "application/x-www-form-urlencoded").build();client.newCall(request).enqueue(new Callback() {@Overridepublic void onFailure(@NonNull Call call, @NonNull IOException e) {Log.e("tag", "获取access token 失败");}@Overridepublic void onResponse(@NonNull Call call, @NonNull Response response) throws IOException {JSONObject jsonObject = JSONObject.parseObject(response.body().string());String access_token1 = jsonObject.getString("access_token");if (!StringUtils.isBlank(access_token1)) {access_token[0] = access_token1;firstCallback.callback(access_token[0]);Log.e("tag", "获取access token==" + access_token[0]);}}});}public void requestSecond(String access_token, String message) throws IOException {Gson gson = new Gson();ChatWxyyRequestBean chatWxyyRequestBean = new ChatWxyyRequestBean();chatWxyyRequestBean.setRole("user");chatWxyyRequestBean.setContent(message);ChatWxyyBodyBean chatWxyyBodyBean = new ChatWxyyBodyBean();chatWxyyRequestBeanList.add(chatWxyyRequestBean);chatWxyyBodyBean.setMessages(chatWxyyRequestBeanList);chatWxyyBodyBean.setTemperature(0.95);chatWxyyBodyBean.setTop_p(0.8);chatWxyyBodyBean.setPenalty_score(1);chatWxyyBodyBean.setDisable_search(false);chatWxyyBodyBean.setEnable_citation(false);chatWxyyBodyBean.setResponse_format("text");chatWxyyBodyBean.setStream(true);//支持流式输出String jsonStr = gson.toJson(chatWxyyBodyBean);//比如将对话对话打包{\"messages\":[{\"role\":\"user\",\"content\":\"你好\"}]}Log.e("tag", "构造的json数据:" + jsonStr);
//        设置请求头MediaType mediaType = MediaType.parse("application/json;charset=utf-8");RequestBody requestBody = RequestBody.create(jsonStr, mediaType);Request request = null;Log.e("tag", "这里是getAccessToken(API_KEY,SECRET_KEY)==" + access_token);request = new Request.Builder().url("https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/ernie-3.5-8k-0205?access_token=" + access_token).method("POST", requestBody).addHeader("Content-Type", "application/json").build();client.newCall(request).enqueue(new Callback() {@Overridepublic void onFailure(@NonNull Call call, @NonNull IOException e) {//Failed callbackcallback.onFailed("请求失败的原因：" + e.getMessage());}@Overridepublic void onResponse(@NonNull Call call, @NonNull Response response) throws IOException {if (!response.isSuccessful()) {throw new IOException("Unexpected code " + response);} else {StringBuffer sb = new StringBuffer();BufferedReader bf = new BufferedReader(response.body().charStream());String line;while ((line = bf.readLine()) != null) {if (line.equals("")) {continue;}// 提取JSON字符串（去掉"data: "前缀）String jsonString = line.substring(line.indexOf(':') + 1).trim();//直接提取后面的{}内的字符串，data: {"id":"as-vdb8b44zzu","object":"chat.completion","created":1717511275,"sentence_id":0,"is_end":false,"is_truncated":false,"result":"你好，","need_clear_history":false,"finish_reason":"normal","usage":{"prompt_tokens":1,"completion_tokens":0,"total_tokens":1}}JSONObject jsonObject = JSON.parseObject(jsonString);// 获取result字段的值String ret = jsonObject.getString("result");sb.append(ret);handleUI(callback,sb.toString());
//                        callback.onSuccess(sb.toString());//将获取到result字符串回调给homefragment中}handleContent(callback,sb.toString());}}});}/*** 处理获取到ai结果的后续* @param callback* @param result*/public abstract void handleContent(AiExample.ICallback callback,String result);///*** 处理获取到ai结果后的UI更新* @param callback* @param result*/public abstract void handleUI(AiExample.ICallback callback,String result);//----------------------------------------------------分割线---------------------------------------------------------/***回调接口,向外暴露回调信息，比如让activity，或者fragment继承此接口，然后设置接口就可以*/public interface ICallback {public void onSuccess(String s);public void onFailed(String errMsg);}ICallback callback;public void setListener(ICallback callback) {this.callback = callback;}}

第五步：如何调用封装类方法实现文心一言请求。

5.1.继承父类AiExample。

如下所示：

WXYYService.java

public class WXYYService extends AiExample{public WXYYService(Context context) {super(context);}@Overridepublic void handleContent(ICallback callback,String result) {if(callback!=null){callback.onSuccess(TextReplaceUtils.replaceText(result));//将获取到result字符串回调给homefragment中//将回复的内容作为下次请求的参数ChatWxyyRequestBean chatWxyyRequestBean1 = new ChatWxyyRequestBean();chatWxyyRequestBean1.setRole("assistant");chatWxyyRequestBean1.setContent(result.toString());chatWxyyRequestBeanList.add(chatWxyyRequestBean1);//这里直接把生成的文章存储到数据库中，如果不是用于展示对话的记录，下面这段可以不需要String title = ArticleUtils.convertArticleTitle(TextReplaceUtils.replaceText(result));//获取文章标题String content = ArticleUtils.convertArticleContent(TextReplaceUtils.replaceText(result));//获取文章内容ArticleHistoryBean articleHistoryBean = new ArticleHistoryBean();articleHistoryBean.setArticle_title(title);articleHistoryBean.setArticle_content(content);new ArticleHistoryDao().insert(articleHistoryBean);}}@Overridepublic void handleUI(ICallback callback, String result) {if(callback!=null){callback.onSuccess(result);}}}

5.2如何使用调用请求

关键代码：创建一个封装好的业务对象

 chatGptExample = new WXYYService(getActivity());//new 一个WXYYService对象

继承回调接口：

public class HomeFragment extends Fragment implements View.OnClickListener, View.OnTouchListener, AiExample.ICallback {

回调设置好了以后设置监听对象，用于文心一言的返回文本供UI显示

        chatGptExample.setListener(this);//设置监听器，为了回调显示UI

在回调接口中更新你的UI信息，需要在UI线程中：

 @Overridepublic void onSuccess(String data) {Log.e("tag", "进入回调监听成功");chatMsgList.get(chatMsgList.size() - 1).setContent(data);//将流对象拼接字符串到显示框中try {getActivity().runOnUiThread(new Runnable() {@Overridepublic void run() {if (chatMsgList != null && data != null) {
//                        chatAdapter.notifyItemInserted(chatMsgList.size() - 1);
//                        chatAdapter.notifyItemChanged(chatMsgList.size() - 1);//当有新消息时，刷新RecyclerView中的显示chatAdapter.notifyDataSetChanged();chatAdapter.notifyItemRangeChanged(0, chatMsgList.size());linearLayoutManagerWrap.setStackFromEnd(true);recyclerView.setLayoutManager(linearLayoutManagerWrap);recyclerView.scrollToPosition(chatMsgList.size() - 1);//将RecyclerView定位到最后一行editText.setText("");showContent(data);//显示界面}}});} catch (Exception e) {}}
