Java中免费使用gpt3_java使用chatgpt免费版本的gpt3-api

使用Java免费使用gpt3

由于OpenAI官方并未提供适用于Java的jar包, 所以只能另辟蹊径。如果你知道其他Java调用OpenAI接口的方法, 欢迎分享。

1.前期准备

1.1. 环境要求

• 安装Java 8+
• 安装Python 3+

1.2. 领取免费gpt3的api key

访问 https://free.gpt.ge/github 领取gpt3的api key,需要使用github账号登录

2.准备Python代码

import os
import openai
import sys
import json

openai.api_key = "输入你获取的apikey"

openai.base_url = "https://free.gpt.ge/v1/"  #中转
openai.default_headers = {"x-foo": "true"}

while True:
    try:
        input_data = sys.stdin.readline().strip()
        if not input_data:
            continue
        message_content = json.loads(input_data)["message"]
        
        if message_content.lower() == "quit":
            break

        completion = openai.chat.completions.create(
            model="gpt-3.5-turbo",
            messages=[
                {
                    "role": "user",
                    "content": message_content,
                },
            ],
        )
        print(completion.choices[0].message.content + "response_end")
        sys.stdout.flush()
    except Exception as e:
        print(f"异常: {e}")
        sys.stdout.flush()

package com.t.demo;

import java.io.*;
import java.util.Scanner;

public class ChatGptController {
    public static void main(String[] args) {
        try {
            // 设置ProcessBuilder,使用绝对路径
            ProcessBuilder pb = new ProcessBuilder("python", "C:\\Users\\locky\\Documents\\code\\demo\\src\\main\\java\\com\\t\\demo\\test.py");
            pb.environment().put("PYTHONIOENCODING", "UTF-8");
            Process process = pb.start();

            // 获取进程的输入输出流
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));

            Scanner sc = new Scanner(System.in);
            while (true) {
                System.out.print("你：");
                String messageContent = sc.nextLine();
                if (messageContent.equals("quit")) break;

                writer.write("{\"message\":\"" + messageContent + "\"}\n");
                writer.flush();

                StringBuilder output = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    output.append(line).append("\n");
                    if (line.contains("response_end")) { // 确保读取到完整的响应
                        break;
                    }
                }
                System.out.println("ChatGPT：" + output.toString().replace("response_end", "").trim());
            }
            writer.close();
            reader.close();            
            process.destroy(); //关闭python进程
        } catch (Exception e) {
            System.out.println("异常!!");
            e.printStackTrace();
        }
    }
}
