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: 实际上,我实际上是在尝试使用Volley对PC上托管的Symfony2 api进行简单的GET请求,首先,我尝试了一些教程,可从此处http://httpbin.org/get?site=code&network=tutsplus获取JSON并成功很好...然后我开始尝试从api中获取JSON,但是出现一些错误,我无法弄清楚为什么,这是日志:

The request is as simple as: 该请求很简单:
@Override protected void onCreate(Bundle savedInstanceState) { @Override受保护的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 : 我的AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

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"}]
它应该获取的JSON是[{"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... 我对此感到非常沮丧,因为我无法修复它...
How does the webserver run? 网络服务器如何运行?
With embed php server, nginx, apache, other web server? 与嵌入php服务器,nginx,apache或其他网络服务器? (what is the vhost conf) (什么是vhost conf)
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
