Question

我正在开发一个与我编写的RESTful Web服务进行通信的Android应用程序。使用Volley进行GET方法时，表的名称很棒且容易，但是我不能把手指放在他没有表名的get方法上

我如何从我的帖子请求的回复中获取字段这是我的回复

enter code here

 [
 {
    "fullname": "IDRISS SAMI",
    "accountnumber": "0825005896788",
    "rib": "10403082500589678844",
    "iban": "",
    "name": "COMPTE SPECIAL EPARGNE",
    "balance": "1462,6580"
},
{
    "fullname": "IDRISS SAMI",
    "accountnumber": "0821006348788",
    "rib": "10403082100634878827",
    "iban": "",
    "name": "COMPTE CHEQUE",
    "balance": "6105,5590"
}

] 这是我的代码

enter code here
 JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    try {
                        JSONArray jsonArray = response.getJSONArray("");

                        for (int i = 0; i < jsonArray.length(); i++) {
                            JSONObject employee = jsonArray.getJSONObject(i);

                            String firstName = response.getString("fullname");
                            int age = employee.getInt("accountnumber");
                            String mail = employee.getString("name");
                             Toast.makeText(ActivityUserProfile.this, "ok"+firstName, Toast.LENGTH_LONG).show();


                            mTextViewResult.append(firstName + ", " + String.valueOf(age) + ", " + mail + "\n\n");
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
        }
    });

    mQueue.add(reques);
}

}

看起来你得到一个JSONArray作为响应，在这种情况下你需要使用JSONArrayRequest。

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

- (void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

W / System.err：at com.android.volley.toolbox.JsonObjectRequest.parseNetworkResponse（JsonObjectRequest.java:73）
