AI 对话

以下版本除了最简单的AI对话，还完善了一下功能。

以下是部分代码，完整代码请移步GIT。

v0版本：基础

聊天

v1版本：对话

新建新对话

可以置顶（取消置顶）、删除、修改对应的对话

数据表

create table tag
(id       int auto_incrementprimary key,user_id  int           not null,tag_name varchar(16)   not null,top      int default 0 null
);create table conversation
(id           int auto_incrementprimary key,tag_id       int         null,user_message text        null,bot_message  text        null,create_time  varchar(32) null,username     varchar(16) null
);

tag.js

v2版本：回复中

用户发送问题之后，显示回复中，得到回复后显示。

前端发送请求之后，先会得到“回复中”；
之后，去轮询获取最新回复。

后端接受请求之后，先存入到数据库中一个未回复请求。
然后异步得到回复之后，再去更新数据库。

textarea.js

var textarea = document.getElementById("messageInput");var isSendingMessage = false; // 添加一个变量用于标识是否正在发送消息textarea.addEventListener("keydown", function(event) {if (event.key === "Enter" && !event.shiftKey) {event.preventDefault();if (isSendingMessage) {// 如果正在发送消息，则在文本框中添加换行符textarea.value += "\n";} else{var message = textarea.value.trim();textarea.value = "";if(!message){alertBox("输入内容不能为空！");return false;}var tagId=$.getUrlParam("tagId");;if(!tagId){alertBox("没有对应的参数");return false;}isSendingMessage = true; // 设置为true表示正在发送消息$.ajax({type: "POST",url: SERVER_PATH+"/chat/chat",data:{"tagId": tagId,"content":message},xhrFields: {withCredentials: true},success:function(result){isSendingMessage = false; // 发送完成后设置为falseif (result.status) {alertBox(result.data.message);return false;}//请求成功之后list(tagId);getChat(result.data.id);}});}}
});textarea.addEventListener("keydown", function(event) {if (event.key === "Enter" && event.shiftKey) {// 在 Shift+Enter 情况下允许换行textarea.value += "\n";event.preventDefault();}
});function getChat(chatId){var tagId=$.getUrlParam("tagId");;$.ajax({type: "GET",url: SERVER_PATH+"/chat/getChat",data:{"id": chatId,},xhrFields: {withCredentials: true},success:function(result){isSendingMessage = false; // 发送完成后设置为falseif (result.status) {alertBox(result.data.message);return false;}if (result.data.botMessage == "回复中...") {// 继续轮询，100ms 一次setTimeout(function() {getChat(chatId);}, 100);} else {// 获取到最终回复// 处理回复逻辑list(tagId);}}});
}

ChatController

    @PostMapping("/chat")public ResponseModel chat(Integer tagId,String content){if (tagId==null){throw new BusinessException(PARAMETER_ERROR,"没有指定响应的tag");}if (StringUtils.isEmpty(content)){throw new BusinessException(PARAMETER_ERROR,"输入内容不能为空");}Tag tag = tagService.searchById(tagId);if (tag==null){throw new BusinessException(NOT_FIND,"没有找到对应的对话");}String username=userService.selectUserById(tag.getUserId()).getUsername();Conversation conversation = new Conversation(null, tagId,username, content, "回复中...", format(new Date()));chatService.addChat(conversation);// 异步处理AI回复CompletableFuture.runAsync(() -> {Integer id=conversation.getId();String res = null;try {res = qianfanUtil.addMessage(content);} catch (Exception e) {res = "回复失败";}Conversation aiConversation = new Conversation();aiConversation.setId(id);aiConversation.setBotMessage(res);chatService.updateChat(aiConversation);});return new ResponseModel(conversation);}

v3版本：流式输出

流式输出，终止生成。

前端实现，让消息一个字符一个字符显示

chatLast.js

var lastId;
var interval;$(document).ready(function () {$("#stopButton").on("click", function() {var latestReply = $(".latest-reply");var latestReplyText = latestReply.text();clearInterval(interval); // 停止字符流输出$("#stopButton").hide();updateStop(lastId,latestReplyText);});});function listLastReply(tagId) {$.ajax({type: "GET",url: SERVER_PATH + "/chat/list",data: {tagId: tagId},xhrFields: {withCredentials: true},success: function (result) {if (result.status) {alertBox(result.data.message);return false;}set_conversations_last(result.data);}});
}function set_conversations_last(conversations) {if (!conversations) {return false;}$(".conversation-list").empty();var len=conversations.length;$.each(conversations, function (i, conversation) {var questionDiv = '<div class="question-container">' +'<table class="question">' +'<td>' +'<span>' + conversation.createTime + '</span>' +'<div class="user-message">' + conversation.userMessage + '</div>' +'</td>' +'<td type="text">' + conversation.username + '</td>' +'</table>' +'</div>';var answerDiv = '<div class="answer-container">' +'<table class="answer">' +'<td type="text">AI</td>' +'<td>' +'<span>' + conversation.createTime + '</span>' +'<div class="bot-message">' + conversation.botMessage + '</div>' +'</td>' +'</table>' +'</div>';if(i!=len-1){$(".conversation-list").append(questionDiv);$(".conversation-list").append(answerDiv);}});// 获取最新对话的回复var lastConversation = conversations[len - 1];lastId=lastConversation.id;var questionDiv = '<div class="question-container">' +'<table class="question">' +'<td>' +'<span>' + lastConversation.createTime + '</span>' +'<div class="user-message">' + lastConversation.userMessage + '</div>' +'</td>' +'<td type="text">' + lastConversation.username + '</td>' +'</table>' +'</div>';$(".conversation-list").append(questionDiv);var answerDiv = '<div class="answer-container">' +'<table class="answer">' +'<td type="text">AI</td>' +'<td>' +'<span>' + lastConversation.createTime + '</span>' +'<div class="bot-message latest-reply">' + lastConversation.botMessage + '</div>' +'</td>' +'</table>' +'</div>';$(".conversation-list").append(answerDiv);// 逐字显示最新回复var latestReply = $(".latest-reply");var latestReplyText = latestReply.text();latestReply.empty();var index = 0;interval = setInterval(function() {if (index < latestReplyText.length) {$("#stopButton").show();latestReply.append(latestReplyText.charAt(index));index++;} else {clearInterval(interval);$("#stopButton").hide();}}, 10); // 逐字显示的速度，您可以根据需要调整}function updateStop(tagId,message){$.ajax({type: "POST",url: SERVER_PATH + "/chat/updateStop",data: {id: tagId,botMessage: message},xhrFields: {withCredentials: true},success: function (result) {if (result.status) {alertBox(result.data.message);return false;}}});
}

ChatController

    @PostMapping("/updateStop")public ResponseModel updateStop(Integer id,String botMessage){Conversation conversation=new Conversation();conversation.setId(id);conversation.setBotMessage(botMessage);chatService.updateChat(conversation);return new ResponseModel();}

v4版本：多轮对话

实现上下文有关的对话

多次调用qianfan.addMessage().addMessage()

QianfanUtil

    public String addMessagePlus(List<Message> messages, String content) {ChatResponse response = qianfan.chatCompletion().messages(messages).addMessage("user", content).temperature(0.7).execute();return response.getResult();}

ChatController

@PostMapping("/chat")public ResponseModel chat(Integer tagId, String content) {if (tagId == null) {throw new BusinessException(PARAMETER_ERROR, "没有指定响应的tag");}if (StringUtils.isEmpty(content)) {throw new BusinessException(PARAMETER_ERROR, "输入内容不能为空");}Tag tag = tagService.searchById(tagId);if (tag == null) {throw new BusinessException(NOT_FIND, "没有找到对应的对话");}String username = userService.selectUserById(tag.getUserId()).getUsername();Conversation conversation = new Conversation(null, tagId, username, content, "回复中...", format(new Date()));chatService.addChat(conversation);// 异步处理AI回复CompletableFuture.runAsync(() -> {Integer id = conversation.getId();String res = null;try {
//                res = qianfanUtil.addMessage(content);res = qianfanUtil.addMessagePlus(getMessages(tagId), content);} catch (Exception e) {res = "回复失败";}Conversation aiConversation = new Conversation();aiConversation.setId(id);aiConversation.setBotMessage(res);chatService.updateChat(aiConversation);});return new ResponseModel(conversation);}public List<Message> getMessages(Integer tagId) {List<Message> messages = new ArrayList<>();List<Conversation> conversations = chatService.searchByTagId(tagId);int size = conversations.size() - 1;//最新的不需要for (int i = 0; i < size; i++) {Conversation conversation = conversations.get(i);Message userMessage = new Message();userMessage.setRole("user");userMessage.setContent(conversation.getUserMessage());messages.add(userMessage);Message botMessage = new Message();botMessage.setRole("assistant");botMessage.setContent(conversation.getBotMessage());messages.add(botMessage);}return messages;}

v5：其他修改

前端样式：跳转到最后一个消息

在aichat.html中

		<script>function scrollToLastMessage() {// 找到消息容器var messageContainer = document.querySelector(".message-container");// 找到消息容器中最后一个子元素var lastMessage = messageContainer.lastElementChild;// 将最后一个消息元素滚动到可见区域lastMessage.scrollIntoView({ behavior: 'auto', block: 'end' });}function onLoad() {setTimeout(scrollToLastMessage, 100); // 添加100毫秒的延迟}window.addEventListener('load', onLoad);</script>

前端样式：Message保留空白符

savePre(conversation.userMessage)
savePre(conversation.botMessage)

function savePre(content){return content.replace(/\n/g, "<br>").replace(/ /g, "<span>&nbsp;</span>");
}

前端样式：最新回复保留空白符

   var botMessageWithBrAndSpace = lastConversation.botMessage.replace(/\n/g, "\\n");var answerDiv = '<div class="answer-container">' +'<table class="answer">' +'<td type="text">AI</td>' +'<td>' +'<span>' + lastConversation.createTime + '</span>' +'<div class="bot-message latest-reply">' + botMessageWithBrAndSpace + '</div>' +'</td>' +'</table>' +'</div>';$(".conversation-list").append(answerDiv);// 逐字显示最新回复var latestReply = $(".latest-reply");var latestReplyText = botMessageWithBrAndSpace;latestReply.empty();var index = 0;interval = setInterval(function() {if (index < latestReplyText.length) {$("#stopButton").show();if (latestReplyText.charAt(index) === "\\") {if (latestReplyText.charAt(index + 1) === "n") {latestReply.append("<br>");index++; // 跳过"n"} else {latestReply.append(latestReplyText.charAt(index));}} else if(latestReplyText.charAt(index)===' '){latestReply.append("&nbsp;");}else {latestReply.append(latestReplyText.charAt(index));}index++;} else {clearInterval(interval);$("#stopButton").hide();}}, 25); // 逐字显示的速度，您可以根据需要调整}
