请用java写一份调用 文心一言api的 示例代码

以下是一个使用Java调用文心一言API的示例代码：

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

public class WenxinYiyanApiDemo {
    public static void main(String[] args) {
        String apiUrl = "https://v1.hitokoto.cn"; // API地址
        String charset = "utf-8"; // 字符集
        String responseType = "text/plain"; // 响应类型

        try {
            URL url = new URL(apiUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Accept-Charset", charset);
            connection.setRequestProperty("Accept", responseType);

            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), charset));
            String line;
            StringBuilder responseBuilder = new StringBuilder();

            while ((line = reader.readLine()) != null) {
                responseBuilder.append(line);
            }

            reader.close();
            connection.disconnect();

            String response = responseBuilder.toString();
            System.out.println(response);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

此代码使用Java的URL和HttpURLConnection类来发送GET请求，并使用BufferedReader类读取响应。在请求的头部中，需要设置Accept-Charset和Accept属性来指定字符集和响应类型。读取响应后，将其转换为字符串并输出。
