分享一个单文件的 ChatGPT api接口实现

banro512

一个非常简单的单文件 ChatGPT api接口实现

最终效果图如下.


使用说明

  1. 基于webman,首先要安装好webman

  2. 然后安装 OpenAI 的官方php库

    composer require openai-php/client
    composer require guzzlehttp/guzzle

  3. api在国内已被墙,但官方库(< v0.4.0)不支持使用代理,所以需要手动修改官方库,添加代理支持

打开 vendor\openai-php\client\src\OpenAI.php
将在 第29行 附近的代码 $client = new GuzzleClient(); 改为

  $client = new GuzzleClient([
            "proxy"=>"你的代理 http://ip:端口"
  ]);

比如我的代理地址是 127.0.0.1:7890 则修改后是:

        $client = new GuzzleClient([
            "proxy"=>"http://127.0.0.1:7890"
        ]);

新版 >= 0.4 以后 openai库有变化,无需再改动官方库了

  1. 将该文件放在某个控制器目录下,然后访问 http://域名/chatgpt 如果有模块,则访问 http://域名/模块/chatgpt

  2. php start.php restart 重启你的应用

全部代码如下


<?php
namespace app\controller;
use support\Request;
use OpenAI\Client;
// openai 的 key
// 全局代理后,在这里注册登录 https://platform.openai.com/signup 
define('OPENAI_KEY', '填写你的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 {
            // 旧版 <0.4 OpenAI 库 使用该代码 
            $response = OpenAI::client(OPENAI_KEY)->chat()->create([
                'model' => 'gpt-3.5-turbo',
                'messages' => $messages
            ]);
            // 新版 >=0.4 OpenAI 库使用该代码 
            /*
            $response=OpenAI::factory()
                ->withApiKey(OPENAI_KEY)
                ->withHttpClient(new \GuzzleHttp\Client([
                        "proxy"=>"你的代理 http://ip:端口"
              ]))->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

https 域名的怎么代理呢

截图
这里没有$client = new GuzzleClient();这行代码怎么整

  • banro512 2023-03-20

    新版的 OpenAI 库有变化,不要手动去修改官方库了
    直接将请求时的代码

    $response = OpenAI::client(OPENAI_KEY)->chat()->create([
                    'model' => 'gpt-3.5-turbo',
                    'messages' => $messages
                ]);

    改为

            $response=OpenAI::factory()
                ->withApiKey(OPENAI_KEY)
                ->withHttpClient(new \GuzzleHttp\Client([
                        "proxy"=>"你的代理 http://ip:端口"
              ]))->make()->chat()->create([
                'model' => 'gpt-3.5-turbo',
                'messages' => $messages
            ])

    {
    "code": 500,
    "msg": "OpenAI\Factory::withHttpClient(): Argument #1 ($client) must be of type Psr\Http\Client\ClientInterface, GuzzleHttp\Client given, called in D:\Desktop\chatGptApi\app\controller\ChatgptController.php on line 30",

    }

    替换完之后报这个错了

    <?php
    use OpenAI\Client;

    $response=OpenAI::factory()
                    ->withApiKey('sk-********************')
                    ->withHttpClient(new \GuzzleHttp\Client([
                            "proxy"=>"http://127.0.0.1:8581"
                  ]))->make()->chat()->create([
                    'model' => 'gpt-3.5-turbo',
                    'messages' => [['role' => 'user', 'content' => '写一段python代码,输出hello world']]
                ]);
    print_r($response);     
    

    实测无问题,有可能你的 guzzlehttp库太久了吧。更新下composer require guzzlehttp/guzzle

    升级后可以了,感谢分享
