android - Volley 库使服务器无响应

Question

我是 volley 的新手，我在我的应用程序中添加了 volley 库，当我向它发出请求时，它将完美工作 1 或 2 天，之后该应用程序停止并给出 volley 服务器未响应错误。我已经检查了很多关于它的链接，但问题仍然得到解决。这是我的截击请求代码:

StringRequest stringRequest = new StringRequest(Request.Method.POST, mainUrl, new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
        try {
            JSONObject obj = new JSONObject(response);
            mainWVUrl = obj.getString("url");
            Log.d(TAG, "MainWVUrl" + mainWVUrl);
            JSONArray jsonArray = obj.getJSONArray("timeRange");
            for (int i = 0; i < jsonArray.length(); i++) {
                minTime = jsonArray.getInt(0);
                maxTime = jsonArray.getInt(1);
            }
            Boolean WVVisible = obj.getBoolean("visible");

            Bundle args1 = new Bundle();
            args1.putString(MAINURL, mainWVUrl);
            args1.putBoolean(WVBOOLEAN, WVVisible);
            broadcastIntent.putExtra(BUNDLE1, args1);
            TimeOut = TimeUnit.SECONDS.toMillis(obj.getInt("timeout"));
            String javaScriptUrl = obj.getString("smsUrl");
            Util.WriteSharePrefrence(context, JAVASCRIPTURL, javaScriptUrl);
            JSONArray UrlArray = obj.getJSONArray("urls");
            for (int j = 0; j < UrlArray.length(); j++) {
                JSONObject jsonObject = UrlArray.getJSONObject(j);
                String subUrl = jsonObject.getString("url");
                long time = jsonObject.getInt("time");

                UrlTimeModel urlTimeModel = new UrlTimeModel();
                urlTimeModel.setSubUrl(subUrl);
                urlTimeModel.setTime(time);
                modelArrayList.add(urlTimeModel);
            }
            if (startService.equalsIgnoreCase("start")) {
                Bundle args = new Bundle();
                args.putSerializable(LIST, (Serializable) modelArrayList);
                args.putLong(TIMEOUT, TimeOut);
                broadcastIntent.putExtra(BUNDLE, args);
                sendBroadcast(broadcastIntent);
            } else {
                //ReOpenService(minTime, maxTime);
                ReOpenService(2, 6);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
},
new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Log.d(TAG, "VolleyError" + error);
    }) {
    @Override
    protected Map<String, String> getParams() throws AuthFailureError {
        Map<String, String> stringMap = new HashMap<>();
        stringMap.put("?device=", Util.DeviceId(AutoOpenAppService.this));
        stringMap.put("&rand=", UUID.randomUUID().toString());
        Log.d(TAG, "VolleyMap" + stringMap);
        return stringMap;
    }
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);

我使用 POST 请求发送数据。

您需要像这样更改请求参数键..

@Override
    protected Map<String, String> getParams() throws AuthFailureError {
        Map<String, String> stringMap = new HashMap<>();
        stringMap.put("device", Util.DeviceId(AutoOpenAppService.this));
        stringMap.put("rand", UUID.randomUUID().toString());
        Log.d(TAG, "VolleyMap" + stringMap);
        return stringMap;
    }
