使用Volley的发布方法不起作用

json

嗨,我正在使用Volley我的登录页面。我需要像这样传递数据

{
userID : '-988682425884628921',
email :'aditya@vyas.com',
passwd : '123ss'
}

我正在使用POST方法发送数据,我已经在DHC中进行了检查,Api在DHC中工作正常,并且我正在获取JSON
Response
,但是当我尝试使用Volley时,我无法获得响应。甚至在我的logcat中也没有任何错误。

JAVA代码

 RequestQueue mVolleyQueue = Volley.newRequestQueue(this);

    CustomRequest req = new CustomRequest(Request.Method.POST,url,null,
            new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    Log.v("tag","login response " + response);
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.v("tag","login error response " + error.getMessage());
        }
    }){
        @Override
        public Map<String, String> getParams() throws AuthFailureError {
            Map<String, String>  params = new HashMap<String, String>();

            params.put("userID", "-988682425884628921");
            params.put("email", "aditya@vyas.com");
            params.put("passwd", "123ss");
            return params;
        }


            @Override
            public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> headers = new HashMap<String, String>();
                headers.put("Content-Type", "application/json; charset=utf-8");
                return headers;
        }
    };
    mVolleyQueue.add(req);

解决了您的问题。刚刚使用JsonArrayRequest和传递的参数JsonObject形式:

    Map<String, String> params = new HashMap<String, String>();
    params.put("userID", "userid");
    params.put("email","email");
    params.put("passwd", "password");
    JsonArrayRequest request = new JsonArrayRequest(Request.Method.POST, "url", new JSONObject(params),
            new Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {
                    System.out.println("response -->> " + response.toString());
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    System.out.println("change Pass response -->> " + error.toString());
                }
            });

    request.setRetryPolicy(new

            DefaultRetryPolicy(60000,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));


    Volley.newRequestQueue(activity).add(request);

无需覆盖getParams()getHeaders()

问题:1 因为服务器接受了as 并且我们正在尝试提供数据,所以 您获得 响应代码500
params``JsonObject``String

问题:2
您正在使用,JsonObjectRequet但是来自服务器的响应已进入,JsonArray因此您需要使用JsonArrayRequest来接受JsonArray

尝试让我知道这是否有帮助:)
