项目效果图：

1.基于webman，所以需要先安装webman框架，若不会使用webman我已将完整项目放置文末，windows下双击.bat文件就能运行。

2.然后安装 OpenAI 的官方php库

composer require openai-php/client

3.安装guzzlehttp扩展

composer require guzzlehttp/guzzle

4.需要准备一个本地代理，作为请求api的代理

5.将代码放到控制器目录下即可，运行方式然后访问http://域名/chatgpt，如果有模块则访问http://域名/模块/chatgpt

完整代码：

<?php
namespace app\controller;
use support\Request;
use OpenAI;

// openai 的 key
// 全局代理后,在这里注册登录 https://platform.openai.com/signup
define('OPENAI_KEY', '');//你的key

class ChatgptController{
    // 初始化获取全部已回答
    public function all(Request $request){
        $messages = $request->session()->get('messages', []);

        return json([
            "code"=>0,
            "msg"=>"ok",
            "data"=>$messages
        ]);
    }
    // 单次查询
    public function query(Request $request){
        
        $messages = $request->session()->get('messages', []);
        $messages[] = ['role' => 'user', 'content' => $request->input('message')];
        $current=[];
        try {
            $response = OpenAI::factory()
                ->withApiKey(OPENAI_KEY)
                ->withHttpClient(new \GuzzleHttp\Client([
                    "proxy"=>""//代理地址例如 127.0.0.1:7890
                ]))->make()->chat()->create([
                'model' => 'gpt-3.5-turbo',
                'messages' => $messages
            ]);
            $current = ['role' => 'assistant', 'content' => nl2br($response->choices[0]->message->content)];
        } catch (\Exception $e) {
            $current = ['role' => 'assistant', 'content' => $e->getMessage()];
        }
        $messages[]=$current;
        $request->session()->put('messages', $messages);
        return json([
            "code"=>0,
            "msg"=>"ok",
            "data"=>$current['content']
        ]);
    }
    // 清除
    public function clear(Request $request){
        $request->session()->delete("messages");
        return redirect("/Chatgpt/index");
    }

    public function index(Request $request){
    
        $ip=$request->getRealIp($safe_mode=true);
        file_put_contents("user_ip.txt",$ip.PHP_EOL,FILE_APPEND);
