如何将数组传递给okhttp android

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

import java.io.IOException;

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

        // 构建要发送的数组
        String[] array = {"item1", "item2", "item3"};

        // 将数组转换为JSON字符串
        String json = toJson(array);

        // 设置请求体的媒体类型为JSON
        MediaType mediaType = MediaType.parse("application/json; charset=utf-8");

        // 构建请求体
        RequestBody requestBody = RequestBody.create(mediaType, json);

        // 构建请求
        Request request = new Request.Builder()
                .url("https://example.com/api")
                .post(requestBody)
                .build();

        try {
            // 发送请求并获取响应
            Response response = client.newCall(request).execute();

            // 处理响应
            if (response.isSuccessful()) {
                String responseData = response.body().string();
                System.out.println("Response: " + responseData);
            } else {
                System.out.println("Request failed");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    // 将数组转换为JSON字符串的方法，这里使用了简单的拼接方式，实际项目中可以使用JSON库进行转换
    private static String toJson(String[] array) {
        StringBuilder jsonBuilder = new StringBuilder();
        jsonBuilder.append("[");
        for (int i = 0; i < array.length; i++) {
            jsonBuilder.append("\"").append(array[i]).append("\"");
            if (i < array.length - 1) {
                jsonBuilder.append(",");
            }
        }
        jsonBuilder.append("]");
        return jsonBuilder.toString();
    }
}
