Can't connect to my localhost with Volley to my Symfony2 api

Question

I'm actually trying to do a simply GET request using Volley to my Symfony2 api hosted in my pc, first I tried some tutorials getting the JSON from here http://httpbin.org/get?site=code&network=tutsplus and it worked pretty well... Then I started trying to get the JSON from my api but I get some errors and I cant figure why, here is the log:

The request is as simple as:

@Override protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
String url = "http://192.168.1.44/api/fincas/1";

final JsonObjectRequest jsonRequest = new JsonObjectRequest
        (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                // the response is already constructed as a JSONObject!
                System.out.println(response.toString());
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                error.printStackTrace();
            }
        });

Volley.newRequestQueue(this).add(jsonRequest);
setContentView(R.layout.activity_main);

My AndroidManifest :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.alvaro.pruebarequests">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".Main2Activity"></activity>
    </application>

</manifest>

And the JSON it should get is [{"id":1,"irrigation_type":"type","plant_variety":"variety","hand_number":722,"born_register":"2005-05-05T00:00:00+0000"}]

Im very frustated with this, since I couldn't fix it...

How does the webserver run?

With embed php server, nginx, apache, other web server? (what is the vhost conf)

Answer 2

好吧，我想出了解决方案，我没有标题“ Accept json”，如果有人遇到这个问题，这是解决方法:)只需添加标题
