我正在尝试在Java和toString的两个工作表之间发送数组

import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;

public class ArraySender {
    public static void main(String[] args) {
        // 要发送的数组
        int[] array = {1, 2, 3, 4, 5};

        try {
            // 创建URL对象
            URL url = new URL("http://example.com/api"); // 替换为实际的目标URL

            // 创建HttpURLConnection对象
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);

            // 将数组转换为字符串
            String arrayString = arrayToString(array);

            // 设置请求体内容
            byte[] requestBody = arrayString.getBytes(StandardCharsets.UTF_8);
            connection.setRequestProperty("Content-Type", "application/json");
            connection.setRequestProperty("Content-Length", String.valueOf(requestBody.length));

            // 发送请求
            OutputStream outputStream = connection.getOutputStream();
            outputStream.write(requestBody);
            outputStream.close();

            // 处理响应
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 请求成功
                // TODO: 处理响应数据
            } else {
                // 请求失败
                // TODO: 处理错误
            }

            // 关闭连接
            connection.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // 将数组转换为字符串
    private static String arrayToString(int[] array) {
        StringBuilder sb = new StringBuilder();
        sb.append("[");
        for (int i = 0; i < array.length; i++) {
            sb.append(array[i]);
            if (i < array.length - 1) {
                sb.append(", ");
            }
        }
        sb.append("]");
        return sb.toString();
    }
}
