如何在Volley，Android中返回带有getParams的JsonObject？

public class CustomRequest extends JsonObjectRequest {
    private Map<String, String> params;

    public CustomRequest(int method, String url, JSONObject jsonRequest, Response.Listener<JSONObject> listener, Response.ErrorListener errorListener, Map<String, String> params) {
        super(method, url, jsonRequest, listener, errorListener);
        this.params = params;
    }

    @Override
    protected Map<String, String> getParams() throws AuthFailureError {
        return params;
    }
}

// 创建一个HashMap来存储请求参数
Map<String, String> params = new HashMap<>();
params.put("param1", "value1");
params.put("param2", "value2");

// 创建一个请求队列
RequestQueue requestQueue = Volley.newRequestQueue(context);

// 创建一个JsonObjectRequest对象，并传入自定义的Request类
CustomRequest request = new CustomRequest(Request.Method.POST, url, null,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                // 处理返回的JsonObject
            }
        },
        new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                // 处理错误
            }
        },
        params);

// 将请求添加到请求队列中
requestQueue.add(request);
