要調用ChatGPT接口，你可以使用Java中的HTTP請求來發送POST請求，并將ChatGPT的API端點作為目標URL。以下是一個簡單的Java代碼示例，用于調用ChatGPT接口：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
public class ChatGPTClient {
????public?static?void?main(String[]?args)?{
????????String?apiEndpoint?=?“https://api.openai.com/v1/chat/completions”;
????????String?apiKey?=?“YOUR_API_KEY”;?//?請替換為你的API密鑰
????????try?{
????????????URL?url?=?new?URL(apiEndpoint);
????????????HttpURLConnection?conn?=?(HttpURLConnection)?url.openConnection();
????????????
????????????//?設置請求頭
????????????conn.setRequestMethod(“POST”);
????????????conn.setRequestProperty(“Authorization”,?"Bearer?"?+?apiKey);
????????????conn.setRequestProperty(“Content-Type”,?“application/json”);
????????????//?設置請求體
????????????String?data?=?“{"prompt":?"What?is?the?weather?like?today?",?"max_tokens":?50}”;
????????????
????????????conn.setDoOutput(true);
????????????OutputStream?outputStream?=?conn.getOutputStream();
????????????outputStream.write(data.getBytes());
????????????outputStream.flush();
????????????
????????????//?發送請求并獲取響應
????????????int?responseCode?=?conn.getResponseCode();
????????????BufferedReader?reader?=?new?BufferedReader(new?InputStreamReader(conn.getInputStream()
????????????));
????????????String?line;
????????????StringBuilder?response?=?new?StringBuilder();
????????????while?((line?=?reader.readLine())?!=?null)?{
????????????????response.append(line);
????????????}
????????????reader.close();
????????????
????????????//?處理響應
????????????if?(responseCode?==?200)?{
????????????????System.out.println(“成功調用ChatGPT接口”);
????????????????System.out.println(“響應結果：”?+?response.toString());
????????????????//?在這里對響應進行進一步處理
????????????}?else?{
????????????????System.out.println(“調用ChatGPT接口失敗，HTTP狀態碼：”?+?responseCode);
????????????????//?在這里處理錯誤情況
????????????}
????????????
????????????conn.disconnect();
????????}?catch?(IOException?e)?{
????????????e.printStackTrace();
????????}
????}
}
在上面的代碼示例中，你需要將apiEndpoint變量設置為ChatGPT的API端點URL，將apiKey變量設置為你的OpenAI API密鑰。然后，你可以根據需要設置請求體中的prompt和max_tokens字段。發送請求后，你可以通過conn.getResponseCode()方法獲取HTTP狀態碼，通過conn.getInputStream()方法獲取響應數據。請根據實際的業務邏輯對響應進行進一步處理。
