java请求chatGpt

要请求使用ChatGPT，您需要使用OpenAI的API密钥和适当的REST API请求。以下是使用Java进行ChatGPT请求的基本示例代码：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;

public class ChatGPTRequest {
    public static void main(String[] args) {
        try {
            String apiKey = "YOUR_API_KEY";
            String prompt = "Hello, how are you?";
            String url = "https://api.openai.com/v1/engines/davinci-codex/completions?prompt=" + URLEncoder.encode(prompt, "UTF-8") + "&max_tokens=150&n=1";
            URL obj = new URL(url);
            HttpURLConnection con = (HttpURLConnection) obj.openConnection();
            con.setRequestMethod("POST");
            con.setRequestProperty("Content-Type", "application/json");
            con.setRequestProperty("Authorization", "Bearer " + apiKey);
            BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();
            System.out.println(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

在上面的示例代码中，您需要替换 `YOUR_API_KEY` 为您的OpenAI API密钥， `prompt` 变量设置为您想要发送给ChatGPT的消息。此代码将返回ChatGPT响应的JSON格式。您可以从响应中提取ChatGPT的回复。请注意，此示例代码仅适用于OpenAI的Davinci Codex引擎。如果您使用其他引擎，则需要更改URL。
