java输出一个chatgpt

作为AI语言模型的GPT，需要通过API接口进行调用，获取相应的文本输出。以下是使用Java调用OpenAI GPT-3 API输出chatbot的示例代码：

import java.net.*;
import java.io.*;
import java.util.*;

public class Chatbot {
    public static void main(String[] args) throws Exception {
        String prompt = "Hello, how are you today?";
        String apikey = "YOUR_API_KEY_HERE";
        String url = "https://api.openai.com/v1/engines/davinci-codex/completions";

        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("POST");
        con.setRequestProperty("Content-Type", "application/json");
        con.setRequestProperty("Authorization", "Bearer " + apikey);

        String postJsonData = "{\"prompt\": \"" + prompt + "\", \"max_tokens\": 100, \"temperature\": 0.7}";

        con.setDoOutput(true);
        OutputStream os = con.getOutputStream();
        os.write(postJsonData.getBytes());
        os.flush();
        os.close();

        int responseCode = con.getResponseCode();
        System.out.println("Response Code : " + responseCode);

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        String output = response.toString();
        output = output.substring(output.indexOf("\"text\":") + 8, output.length() - 3);
        System.out.println(output);
    }
}

需要将YOUR_API_KEY_HERE替换为你的OpenAI API密钥。运行程序后，将输出一个与输入prompt相关的chatbot回复。
