android volley 注册时响应代码 500

Question

我使用 volley 库连接到服务器。我有登录和注册方法。它们是相同的，但具有不同的参数。登录方式:

    private void login(String url){
    RequestQueue requestQueue = MyVolley.getRequestQueue();

    Map<String, String> params = new HashMap<String, String>();
    params.put("email", "aubree@wisoky.biz");
    params.put("password", "123456789");
    params.put("person", "0");

    JsonObjectRequest jor = new JsonObjectRequest(Request.Method.POST,
            url,
            new JSONObject(params),
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    conTV.setText(response.toString());

                    Log.d("Reger", response.toString());
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    conTV.setText(error.getMessage());
                }
            }){
        @Override
        public String getBodyContentType() {
            return "application/json; charset=utf-8";
        }
    };

    requestQueue.add(jor);
}

及注册方式:

    private void register(String url){

    RequestQueue requestQueue = MyVolley.getRequestQueue();
    Map<String, String> params = new HashMap<String, String>();
    params.put("email", "lork@more.com");
    params.put("password", "123456789");
    params.put("name", "Lurk");
    params.put("surname", "More");
    params.put("person", "0");

    JsonObjectRequest jor = new JsonObjectRequest(Request.Method.POST,
            url,
            new JSONObject(params),
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    conTV.setText(response.toString());
                    Log.d("Reger", response.toString());
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    conTV.setText(error.toString());
                }
    }){
        @Override
        public String getBodyContentType() {
            return "application/json; charset=utf-8";
        }
    };

    requestQueue.add(jor);
}

问题出在注册方法日志中:

E/Volley﹕ [1608] BasicNetwork.performRequest: Unexpected response code 500 for http://server/api/v1/register

不知道为什么？第一种方法正确但第二种方法不正确。

正如@bharat 所说，看起来您的服务器不可用。我建议您像这样处理此类错误 onErrorResponse:

        NetworkResponse networkResponse = error.networkResponse;
        if (networkResponse != null) {
            Log.e("Volley", "Error. HTTP Status Code:"+networkResponse.statusCode);
        }

        if (error instanceof TimeoutError) {
            Log.e("Volley", "TimeoutError");
        }else if(error instanceof NoConnectionError){
            Log.e("Volley", "NoConnectionError");
        } else if (error instanceof AuthFailureError) {
            Log.e("Volley", "AuthFailureError");
        } else if (error instanceof ServerError) {
            Log.e("Volley", "ServerError");
        } else if (error instanceof NetworkError) {
            Log.e("Volley", "NetworkError");
        } else if (error instanceof ParseError) {
            Log.e("Volley", "ParseError");
        }
