import com.theokanning.openai.completion.CompletionRequest;

import java.io.*;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;

public class OpenAiApi {
    public static String OpenAiAnswerer(CompletionRequest request, String openAiApiKey) {

        // 代理IP
        String proxyHost = "127.0.0.1";
        // 代理端口
        int proxyPort = 7890;
        // 请求地址
        String url = "https://api.openai.com/v1/completions";
        // json为请求体

                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                StringBuilder response = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                result = response.toString();
            }
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        return result;
    }

3.测试运行

    public static void main(String[] args){
        showModels();
    }

    /**
     * 显示模型
     * 根据不同的功能和语言选择合适的模型，可以在官网的模型概述中查看
     * https://platform.openai.com/docs/models/overview
     */
    public static void showModels(){
        CompletionRequest completionRequest = CompletionRequest.builder()
                .model("text-davinci-003")
                .prompt("今天天气怎么样？")
                .temperature(0.5)
                .build();
        String result = OpenAiApi.OpenAiAnswerer(completionRequest, "使用自己的apiKey替代");
        System.out.println(result);
    }
