使用Java调用openai api key程序开发实例

在Java中调用OpenAI API通常需要通过HTTP请求库，如Apache HttpClient、OkHttp或者Spring的RestTemplate来进行。以下是一个简单的示例，展示如何使用HttpClient发送GET请求并处理JSON响应：

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class OpenAIAPICaller {
    private static final String OPENAI_API_KEY = "your_openai_api_key";
    private static final String OPENAI_ENDPOINT = "https://api.openai.com/v1/engines/davinci-codex/completions";

    public static void main(String[] args) throws Exception {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        try {
            HttpGet httpGet = new HttpGet(OPENAI_ENDPOINT);
            httpGet.setHeader("Authorization", "Bearer " + OPENAI_API_KEY);

            CloseableHttpResponse response = httpClient.execute(httpGet);
            try {
                HttpEntity entity = response.getEntity();
                if (entity != null) {
                    String responseBody = EntityUtils.toString(entity, "UTF-8");
                    // 这里你可以解析返回的JSON数据，例如：
                    // JSONObject json = new JSONObject(responseBody);
                    // System.out.println(json.getString("text"));
                } else {
                    System.out.println("No data received from the API.");
                }
            } finally {
                response.close();
            }
        } finally {
            httpClient.close();
        }
    }
}

在这个例子中，你需要替换`your_openai_api_key`为你实际的OpenAI API密钥，并确保你已经添加了必要的依赖于处理HTTP请求和JSON。
