java如何调用chatgpt

在Java中调用ChatGPT，可以使用OpenAI的相关API来实现。下面是一个简单的示例代码：

import okhttp3.OkHttpClient;
import okhttp3.MediaType;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class ChatGPTCaller {
    private static final String API_URL = "https://api.openai.com/v1/chat/completions";
    private static final String API_KEY = "YOUR_API_KEY";

    public static void main(String[] args) {
        OkHttpClient client = new OkHttpClient();

        MediaType mediaType = MediaType.parse("application/json");
        RequestBody body = RequestBody.create(mediaType, "{\"model\": \"gpt-3.5-turbo\",\"messages\": [{\"role\": \"system\",\"content\": \"You are a helpful assistant.\"},{\"role\": \"user\",\"content\": \"Who won the world series in 2020?\"},{\"role\": \"assistant\",\"content\": \"The Los Angeles Dodgers won the World Series in 2020.\"},{\"role\": \"user\",\"content\": \"Where was it played?\"},{\"role\": \"assistant\",\"content\": \"The World Series in 2020 was played in Arlington, Texas at the Globe Life Field, which was the new home stadium for the Texas Rangers.\"}]}\n");
        Request request = new Request.Builder()
                .url(API_URL)
                .post(body)
                .addHeader("Authorization", "Bearer " + API_KEY)
                .addHeader("Content-Type", "application/json")
                .build();

        try {
            Response response = client.newCall(request).execute();
            String responseBody = response.body().string();
            System.out.println(responseBody);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

在上面的代码中，你需要替换`YOUR_API_KEY`为你自己的API密钥。还需要根据对话的内容设置`messages`数组中不同角色的消息。

在这个示例中，我们将使用OpenAI的GPT-3.5-turbo模型，它不需要设置初始文本。你可以根据自己的需求进行调整。

请确保你已经正确引入OkHttp库，并且已经获取到了有效的API密钥。
