ThinkPHP 6 + UniApp环境下接入DeepSeek到微信生态的完整解决方案

大家好，欢迎来到IT知识分享网。

以下是在 后端ThinkPHP 6 + 前端UniApp环境下接入DeepSeek到微信生态的完整解决方案，包含详细步骤和代码示例：

一、准备工作

1. 微信生态配置

小程序

– 设置服务器域名：登录微信公众平台 -> 开发管理 -> 服务器域名

request合法域名：https://yourdomain.com

socket合法域名：wss://yourdomain.com

公众号

– 服务器配置： URL：
https://yourdomain.com/wechat

Token：自定义令牌 EncodingAESKey：随机生成

2. ThinkPHP 6项目初始化

composer create-project topthink/think tp6_deepseek cd tp6_deepseek composer require topthink/think-multi-app # 多应用支持

二、后端开发（ThinkPHP 6）

1. 目录结构

app ├── deepseek │ ├── controller │ │ └── Index.php # DeepSeek接口控制器 │ └── service │ └── DeepseekService.php # 服务层 └── wechat └── controller └── Index.php # 公众号消息处理

2. 核心代码

(1) DeepSeek服务类 //
app/deepseek/service/DeepseekService.php

<?php namespace app\deepseek\service; class DeepseekService { private $apiKey = 'sk-xxx'; // 从.env获取 private $apiUrl = 'https://api.deepseek.com/v1/chat/completions'; public function chat($prompt) { $data = [ 'model' => 'deepseek-chat', 'messages' => [['role' => 'user', 'content' => $prompt]], 'max_tokens' => 1000 ]; $ch = curl_init(); curl_setopt_array($ch, [ CURLOPT_URL => $this->apiUrl, CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => [ 'Content-Type: application/json', 'Authorization: Bearer ' . $this->apiKey ], CURLOPT_POST => true, CURLOPT_POSTFIELDS => json_encode($data) ]); $response = curl_exec($ch); curl_close($ch); return json_decode($response, true); } } 

(2) 控制器实现 //
app/deepseek/controller/Index.php

<?php namespace app\deepseek\controller; use app\BaseController; use app\deepseek\service\DeepseekService; class Index extends BaseController { public function chat() { $input = json_decode(file_get_contents('php://input'), true); $service = new DeepseekService(); $result = $service->chat($input['prompt'] ?? ''); return json([ 'code' => isset($result['choices']) ? 200 : 500, 'data' => $result['choices'][0]['message']['content'] ?? '服务繁忙' ]); } } 

(3) 公众号消息处理 //
app/wechat/controller/Index.php

<?php namespace app\wechat\controller; use app\BaseController; use app\deepseek\service\DeepseekService; class Index extends BaseController { // 验证服务器 public function index() { if ($this->request->get('echostr')) { return $this->request->get('echostr'); } // 处理消息 $xml = $this->request->getContent(); $data = simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA); $service = new DeepseekService(); $response = $service->chat((string)$data->Content); return $this->response->xml([ 'ToUserName' => $data->FromUserName, 'FromUserName' => $data->ToUserName, 'CreateTime' => time(), 'MsgType' => 'text', 'Content' => $response['choices'][0]['message']['content'] ?? '请稍后再试' ]); } } 

3. 路由配置

// config/route.php use think\facade\Route; // DeepSeek接口 Route::post('deepseek/chat', 'deepseek.Index/chat'); // 公众号消息入口 Route::any('wechat', 'wechat.Index/index'); 

三、前端开发（UniApp）

1. 页面实现 <!– pages/chat/index.vue –>

<template> <view class="container"> <!-- 消息列表 --> <scroll-view class="chat-box" scroll-y> <view v-for="(msg,index) in messages" :key="index" :class="['message', msg.role]"> <text>{{ msg.content }}</text> </view> </scroll-view> <!-- 输入区 --> <view class="input-box"> <input v-model="inputMsg" placeholder="输入问题..." @confirm="send"/> <button @click="send">发送</button> </view> </view> </template> <script> export default { data() { return { inputMsg: '', messages: [] } }, methods: { async send() { if (!this.inputMsg.trim()) return; this.messages.push({ role: 'user', content: this.inputMsg }); const msg = this.inputMsg; this.inputMsg = ''; try { const { code, data } = await uni.request({ url: 'https://yourdomain.com/deepseek/chat', method: 'POST', header: { 'Content-Type': 'application/json' }, data: { prompt: msg } }); if (code === 200) { this.messages.push({ role: 'assistant', content: data }); } else { uni.showToast({ title: '服务异常', icon: 'none' }); } } catch (e) { uni.showToast({ title: '网络错误', icon: 'none'}) } } }

四、部署与调试建议

1. Nginx配置建议

server {
    listen 80;
    server_name yourdomain.com;

    location / {
    root /path/to/tp6/public;
    index index.php index.html;

    if (!-e $request_filename) {
    rewrite ^/(.*)$ /index.php/$1 last;
    }
    }

    location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

2. 常见调试技巧

# 实时查看DeepSeek请求日志 tail -f /var/log/nginx/deepseek_access.log | grep "POST /deepseek/chat" # ThinkPHP调试模式 # 修改.env文件 APP_DEBUG = true # 微信接口调试工具 curl -X POST "https://yourdomain.com/wechat" \ -d '<xml>...</xml>' \ -H "Content-Type: text/xml" 

3. 性能优化建议

 // 在DeepseekService中使用连接池 $pool = new Swoole\Coroutine\Channel(10); for ($i = 0; $i < 10; $i++) { $pool->push(new Swoole\Coroutine\Http\Client('api.deepseek.com', 443, true)); } // 请求时复用连接 $client = $pool->pop(); $client->post('/v1/chat/completions', json_encode($data)); $response = $client->body; $pool->push($client);

以上为完整实现方案，可根据实际业务需求调整参数和扩展功能模块。
