📥网站在线客服系统源码开源uniapp下载 ▏PHP/Java全栈开发 ▏支持AI机器人+多国语言
一、系统架构与技术栈概述
1.1 整体架构设计
在线客服系统采用前后端分离架构，前端基于uniapp实现跨平台界面开发，后端支持PHP或Java技术栈，通过RESTful API或WebSocket实现数据交互。系统核心模块包括：用户管理、客服管理、消息通信、AI智能应答、多语言切换等。
源码：s.zxkfym.top
1.2 技术栈详情
前端：uniapp（Vue.js）、Vuex、uni-socket.io
后端（PHP）：Laravel/Slim框架、PHP 7.4+、WebSocket（Ratchet）
后端（Java）：Spring Boot 2.7+、WebSocket（Spring WebSocket）、MyBatis
数据库：MySQL 8.0/PostgreSQL、Redis（缓存）
AI集成：OpenAI API/阿里云小蜜、自然语言处理（NLP）
多语言：Vue I18n、后端国际化配置
二、uniapp前端开发实践
2.1 项目结构与跨平台配置
创建uniapp项目后，核心目录结构如下：
bash
my-chat-system/
├── pages/ 页面文件
│ ├── login/ 登录页
│ ├── chat/ 聊天页
│ ├── agent-list/ 客服列表页
├── static/ 静态资源
│ ├── i18n/ 多语言文件
│ ├── images/ 图标
├── src/
│ ├── store/ Vuex状态管理
│ ├── api/ 接口请求
│ ├── utils/ 工具函数
│ ├── sockets/ WebSocket连接
├── manifest.json 应用配置
├── pages.json 页面路由配置
└── uni.scss 全局样式
2.2 多语言功能实现
在`static/i18n/`目录下创建语言文件，如`zh-CN.json`和`en-US.json`：
json
// zh-CN.json
{
“login”: {
“title”: “用户登录”,
“username”: “用户名”,
“password”: “密码”,
“submit”: “登录”
},
“chat”: {
“input_placeholder”: “请输入消息…”,
“send”: “发送”,
“ai_response”: “智能客服为您解答：”
}
}
// en-US.json
{
“login”: {
“title”: “User Login”,
“username”: “Username”,
“password”: “Password”,
“submit”: “Login”
},
“chat”: {
“input_placeholder”: “Type your message…”,
“send”: “Send”,
“ai_response”: “AI Assistant: “
}
}
在`main.js`中配置Vue I18n：
javascript
import Vue from vue
import App from ./App
import i18n from @/utils/i18n // 自定义i18n工具
Vue.config.productionTip = false
Vue.prototype.$i18n = i18n
App.mpType = app
const app = new Vue({
i18n,
…App
})
app.$mount()
2.3 聊天页面核心代码
vue
<template>
<view class=”chat-container”>
<!-消息列表 –>
<scroll-view scroll-y class=”message-list”>
<view
v-for=”(msg, index) in messages”
:key=”index”
:class=”[ message-item , msg.fromUser ? user-msg : agent-msg ]”
>
<text class=”msg-content”>{{ msg.content }}</text>
<text class=”msg-time”>{{ formatTime(msg.time) }}</text>
</view>
<!-AI机器人提示 –>
<view v-if=”showAiTip” class=”ai-tip”>{{ $t( chat.ai_response ) }}</view>
</scroll-view>
<!-输入区域 –>
<view class=”input-area”>
<input
v-model=”inputMsg”
placeholder=”{{ $t( chat.input_placeholder ) }}”
@confirm=”sendMessage”
/>
<button @click=”sendMessage” class=”send-btn”>{{ $t( chat.send ) }}</button>
</view>
</view>
</template>

this.callAIAPI(message.content).then(aiResult => {
if (aiResult.isSuccess) {
this.messages.push({

})
this.showAiTip = true
setTimeout(() => {

})
})
},
// 加载历史消息

}))
}
}
})
},
// 格式化时间
formatTime(time) {
const date = new Date(time)
return date.toLocaleTimeString()
}
}
}

3.2 RESTful API接口示例（基于Laravel框架）
3.2.1 用户登录接口
php
// app/Http/Controllers/AuthController.php
<?php
namespace AppHttpControllers;
use AppModelsUser;
use IlluminateHttpRequest;
use IlluminateSupportFacadesHash;
use IlluminateSupportFacadesAuth;
class AuthController extends Controller
{
public function login(Request $request)
{
$request->validate([
username => required ,
password => required
]);
$user = User::where( username , $request->username)->first();
if (!$user || !Hash::check($request->password, $user->password)) {
return response()->json([
status => false,
message => 用户名或密码错误
], 401);
}
// 生成JWT令牌
$token = auth( api )->login($user);
return response()->json([
status => true,
data => [
user => $user,
token => $token,
expires_in => auth( api )->factory()->getTTL() * 60
]
]);
}
}
3.2.2 发送消息接口
php
// app/Http/Controllers/ChatController.php
<?php
namespace AppHttpControllers;
use AppModelsChatMessage;
use AppModelsUser;
use AppModelsAgent;
use IlluminateHttpRequest;
use IlluminateSupportFacadesAuth;
class ChatController extends Controller
{
/
* 发送聊天消息
*/
public function sendMessage(Request $request)
{
$request->validate([
agent_id => required|exists:agents,id ,
content => required|string|max:2000
]);
$user = Auth::guard( api )->user();
$agent = Agent::findOrFail($request->agent_id);
// 保存消息到数据库
$message = ChatMessage::create([
user_id => $user->id,
agent_id => $agent->id,
content => $request->content,
from_user => 1,
is_ai => 0
]);
// 调用AI接口（示例）
$aiResult = $this->callAIAPI($request->content, $user->language);
if ($aiResult[ is_success ]) {
// AI能解答，保存AI回复
ChatMessage::create([
user_id => $user->id,
agent_id => $agent->id,
content => $aiResult[ answer ],
from_user => 0,
is_ai => 1
]);
// 推送AI回复给用户（通过WebSocket）
event(new AppEventsAIChatResponseEvent($user->id, $aiResult[ answer ]));
} else {
// AI无法解答，推送给人工客服（通过WebSocket）
event(new AppEventsNewChatMessageEvent($user->id, $agent->id, $request->content));
}
return response()->json([
status => true,
data => $message
]);
}
/
* 调用AI接口
*/
private function callAIAPI($message, $language)
{
// 实际项目中替换为真实的AI接口（如OpenAI、阿里云等）
$apiKey = config( services.ai.api_key );
$apiUrl = config( services.ai.api_url );
// 示例：模拟AI响应
$isSuccess = strpos(strtolower($message), 你好 ) !== false;
return [
is_success => $isSuccess,
answer => $isSuccess ?
($language === zh-CN ? 您好！我是智能客服，请问有什么可以帮您？ : Hello! I am an AI assistant. How can I help you? ) :
($language === zh-CN ? 抱歉，这个问题我暂时无法解答，我将为您转接人工客服。 : Sorry, I can t answer this question for now. I will transfer you to a human agent. )
];
}
}
3.2.3 WebSocket服务（基于Ratchet）
php
// app/Http/Controllers/WebSocket/ChatServer.php
<?php
namespace AppHttpControllersWebSocket;
use RatchetMessageComponentInterface;
use RatchetConnectionInterface;
use AppModelsUser;
use AppModelsAgent;
use AppServicesChatService;
class ChatServer implements MessageComponentInterface
{
protected $clients = []; // 存储客户端连接
public function onOpen(ConnectionInterface $conn)
{
// 解析JWT令牌获取用户信息
$token = $conn->WebSocket->request->getQuery()[ token ] ?? null;
if (!$token) {
$conn->close(4001, 认证失败 );
return;
}
try {
$user = User::find(auth( api )->setToken($token)->user()->id);
if (!$user) {
$conn->close(4001, 用户不存在 );
return;
}
// 记录连接
$this->clients[$conn->resourceId] = [
conn => $conn,
user_id => $user->id,
type => user
];
// 通知客服用户上线
$chatService = new ChatService();
$chatService->notifyAgents($user->id, online );
echo “用户 {$user->id} 已连接
“;
} catch (Exception $e) {
$conn->close(4001, 认证失败: . $e->getMessage());
}
}
public function onMessage(ConnectionInterface $from, $msg)
{
$data = json_decode($msg, true);
if (!$data || !isset($data[ agent_id ]) || !isset($data[ content ])) {
return;
}
$agentId = $data[ agent_id ];
$content = $data[ content ];
// 查找客服连接
$agentConnection = null;
foreach ($this->clients as $id => $client) {
if ($client[ type ] === agent && $client[ agent_id ] === $agentId) {
$agentConnection = $client[ conn ];
break;
}
}
if ($agentConnection) {
// 发送给客服
$agentConnection->send($msg);
} else {
// 客服不在线，返回提示
$from->send(json_encode([
type => system ,
content => 客服当前不在线，消息将被记录
]));
}
}
// onClose和onError方法省略…
}
四、Java后端核心实现（Spring Boot）

4.2 实体类设计
java
// src/main/java/com/chat/entity/User.java
package com.chat.entity;
import javax.persistence.*;
import java.time.LocalDateTime;
@Entity
@Table(name = “users”)
public class User {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String username;
private String password;
private String language = “zh-CN”; // 默认语言

}
// src/main/java/com/chat/entity/ChatMessage.java
package com.chat.entity;
import javax.persistence.*;
import java.time.LocalDateTime;
@Entity
@Table(name = “chat_messages”)
public class ChatMessage {

private LocalDateTime createTime;
// 构造函数、getter和setter省略…
}
4.3 WebSocket配置与服务
java
// src/main/java/com/chat/websocket/ChatWebSocketConfig.java
package com.chat.websocket;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;
@Configuration
public class ChatWebSocketConfig {
@Bean
public ServerEndpointExporter serverEndpointExporter() {
return new ServerEndpointExporter();
}
}
// src/main/java/com/chat/websocket/ChatWebSocket.java
package com.chat.websocket;
import com.chat.entity.User;
import com.chat.service.UserService;
import com.chat.utils.JwtUtil;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.websocket.*;
import javax.websocket.server.PathParam;
import javax.websocket.server.ServerEndpoint;
import java.io.IOException;
import java.util.concurrent.ConcurrentHashMap;
@ServerEndpoint(“/ws/chat/{token}”)
@Component
public class ChatWebSocket {
private static final Logger logger = LoggerFactory.getLogger(ChatWebSocket.class);
private static final ObjectMapper objectMapper = new ObjectMapper();
// 存储连接会话
private static final ConcurrentHashMap<Long, Session> userSessions = new ConcurrentHashMap<>();
private static final ConcurrentHashMap<Long, Session> agentSessions = new ConcurrentHashMap<>();
@Autowired
private UserService userService;
@Autowired
private JwtUtil jwtUtil;
@OnOpen
public void onOpen(Session session, @PathParam(“token”) String token) {
try {
// 解析JWT获取用户ID
Long userId = jwtUtil.getUserIdFromToken(token);
User user = userService.findById(userId);
if (user == null) {
session.close(new CloseReason(CloseReason.CloseCodes.CANNOT_ACCEPT, “用户不存在”));
return;
}
// 记录会话
if (user.isAgent()) { // 客服
agentSessions.put(userId, session);
logger.info(“客服 {} 已连接”, userId);
} else { // 普通用户
userSessions.put(userId, session);
logger.info(“用户 {} 已连接”, userId);
}
// 通知其他客户端
broadcastOnlineStatus(userId, true);
} catch (Exception e) {
try {
session.close(new CloseReason(CloseReason.CloseCodes.CANNOT_ACCEPT, “认证失败: ” + e.getMessage()));
} catch (IOException ex) {
logger.error(“关闭会话失败”, ex);
}
}
}
@OnMessage
public void onMessage(Session session, String message) {
try {
// 解析消息
ChatMessageDto msgDto = objectMapper.readValue(message, ChatMessageDto.class);
Long agentId = msgDto.getAgentId();
// 调用AI接口
AIChatResponse aiResponse = callAIAPI(msgDto.getContent(), msgDto.getLanguage());

}
private static class AIChatResponse {

}
}
五、AI机器人与多语言集成
5.1 AI智能问答集成示例
以下是使用OpenAI API实现智能问答的PHP示例：
php
<?php
// app/Services/AIService.php
namespace AppServices;
class AIService
{
private $apiKey;
private $apiUrl = https://api.openai.com/v1/chat/completions ;
public function __construct($apiKey)
{
$this->apiKey = $apiKey;
}
/
* 调用OpenAI API进行智能问答
*/
public function chat($message, $language = zh-CN )
{
$headers = [
Content-Type: application/json ,
Authorization: Bearer . $this->apiKey
];
// 根据语言设置提示词
$systemPrompt = $language === zh-CN ?
你是一个智能客服，需要简洁明了地回答用户的问题。如果无法回答，需要引导用户联系人工客服。 :
You are an AI customer service assistant. Answer user questions concisely. If you can t answer, guide users to contact human agents. ;
$data = [
model => gpt-3.5-turbo ,
messages => [
[ role => system , content => $systemPrompt],
[ role => user , content => $message]
],
temperature => 0.7
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $this->apiUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($httpCode >= 200 && $httpCode < 300) {
$responseData = json_decode($response, true);
if (isset($responseData[ choices ][0][ message ][ content ])) {
return [
is_success => true,
answer => trim($responseData[ choices ][0][ message ][ content ])
];
}
}
return [
is_success => false,
answer => $language === zh-CN ? 抱歉，当前无法为您解答，请联系人工客服。 : Sorry, I can t answer now. Please contact human agent.
];
}
}
5.2 多语言动态加载实现
在Java后端中实现多语言动态加载：
java
// src/main/java/com/chat/service/LanguageService.java
package com.chat.service;
import com.chat.entity.LanguagePack;
import com.chat.repository.LanguagePackRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@Service
public class LanguageService {
@Autowired
private LanguagePackRepository languagePackRepository;
// 缓存语言包
private Map<String, Map<String, Map<String, String>>> languageCache = new HashMap<>();
/
* 获取语言包内容
*/
public String getMessage(String langCode, String module, String key) {
// 从缓存获取
Map<String, Map<String, String>> moduleCache = languageCache.get(langCode);
if (moduleCache == null) {
// 缓存不存在，从数据库加载
loadLanguagePackToCache(langCode);
moduleCache = languageCache.get(langCode);
}
if (moduleCache == null) {
return “[” + langCode + “:” + module + “:” + key + “]”; // 未找到时返回占位符
}
Map<String, String> keyCache = moduleCache.get(module);
if (keyCache == null) {
return “[” + langCode + “:” + module + “:” + key + “]”;
}
return keyCache.get(key) != null ? keyCache.get(key) : “[” + key + “]”;
}
/
* 加载语言包到缓存
*/
private void loadLanguagePackToCache(String langCode) {
List<LanguagePack> packs = languagePackRepository.findByLangCode(langCode);
Map<String, Map<String, String>> moduleMap = new HashMap<>();
for (LanguagePack pack : packs) {
Map<String, String> keyMap = moduleMap.computeIfAbsent(pack.getModule(), k -> new HashMap<>());
keyMap.put(pack.getKey(), pack.getValue());
}
languageCache.put(langCode, moduleMap);
}
/
* 刷新语言包缓存
*/
public void refreshCache(String langCode) {
languageCache.remove(langCode);
loadLanguagePackToCache(langCode);
}
}
