如何在android中将变量数组传递给REST URL？

import android.net.Uri;
import android.util.Log;

import org.json.JSONArray;

import java.net.MalformedURLException;
import java.net.URL;

public class RestUrlUtils {
    private static final String BASE_URL = "https://api.example.com";

    public static URL buildUrlWithVariables(String[] variables) {
        Uri.Builder builder = Uri.parse(BASE_URL).buildUpon();

        // 将变量数组转换为字符串
        String variablesString = new JSONArray(variables).toString();

        // 添加路径参数
        builder.appendPath("path")
                .appendPath("to")
                .appendPath("resource")
                .appendPath(variablesString);

        // 添加查询参数
        builder.appendQueryParameter("param", variablesString);

        URL url = null;
        try {
            url = new URL(builder.build().toString());
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }

        return url;
    }
}
