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);
