java实现chatgpt流式接口

Java实现ChatGPT的流式接口可以使用OpenAI GPT-3的REST API进行通信。下面是一个简单的示例代码：

import okhttp3.*;
import org.json.JSONObject;

import java.io.IOException;

public class ChatGPTClient {
    private static final String API_ENDPOINT = "https://api.openai.com/v1/engines/davinci/completions";

    private final OkHttpClient client;
    private final String apiKey;

    public ChatGPTClient(String apiKey) {
        this.apiKey = apiKey;
        this.client = new OkHttpClient();
    }

    public String sendMessage(String message) throws IOException {
        RequestBody requestBody = new FormBody.Builder()
                .add("model", "davinci")
                .add("prompt", message)
                .build();

        Request request = new Request.Builder()
                .url(API_ENDPOINT)
                .header("Authorization", "Bearer " + apiKey)
                .post(requestBody)
                .build();

        try (Response response = client.newCall(request).execute()) {
            JSONObject json = new JSONObject(response.body().string());
            String completions = json.getJSONArray("choices").getJSONObject(0).getString("text");
            return completions;
        }
    }

    public static void main(String[] args) {
        ChatGPTClient client = new ChatGPTClient("YOUR_API_KEY");

        try {
            String message = "Hello!";
            while (!message.equals("bye")) {
                String response = client.sendMessage(message);
                System.out.println("AI: " + response);
                // 接收用户输入
                // ...
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

上述代码使用了OkHttp库进行HTTP请求，并使用JSONObject解析响应结果。请确保你替换`YOUR_API_KEY`为你的OpenAI API密钥。

这个示例代码只是一个基本的实现，你可以根据自己的需求进行扩展和优化。
