如何自定义JsonObjectRequest，以便重写volley库中的getParams方法

import com.android.volley.Response;
import com.android.volley.toolbox.JsonObjectRequest;
import org.json.JSONObject;

public class CustomJsonObjectRequest extends JsonObjectRequest {

    public CustomJsonObjectRequest(int method, String url, JSONObject jsonRequest,
                                   Response.Listener<JSONObject> listener, Response.ErrorListener errorListener) {
        super(method, url, jsonRequest, listener, errorListener);
    }

    @Override
    protected Map<String, String> getParams() {
        // 在这里重写getParams方法，自定义请求参数
        Map<String, String> params = new HashMap<>();
        params.put("param1", "value1");
        params.put("param2", "value2");
        return params;
    }
}

String url = "https://example.com/api";
JSONObject jsonRequest = new JSONObject();
// 添加请求体参数
try {
    jsonRequest.put("key1", "value1");
    jsonRequest.put("key2", "value2");
} catch (JSONException e) {
    e.printStackTrace();
}

CustomJsonObjectRequest request = new CustomJsonObjectRequest(Method.POST, url, jsonRequest,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            // 请求成功的回调处理
        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // 请求失败的回调处理
        }
    });

// 将请求添加到请求队列中
RequestQueue queue = Volley.newRequestQueue(context);
queue.add(request);
