使用 volley 向 android 发送 Json 数组 POST 请求 [英] Send a Json array POST request with android using volley

问题描述

我正在开发应用程序，在该应用程序中我使用 volley 将数据发送到服务器，现在我想以 json 数组的形式将数据发送到服务器，但不知道如何在数组中发送??

i am developing application in which i send data to server using volley now i want to send data to server in json array but not know how to send in array??

    Map<String, String> postParam = new HashMap<String, String>();

    postParam.put("Token", "U2FsdGVkX13CFEM=");
    postParam.put("AppDB", "day");
    postParam.put("ContentTypeName", "Users");



    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.POST,
            AppConfig.URL_REGISTER_WITHOUT_IMG, new JSONObject(postParam),
            new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {
                    Log.d(TAG, response.toString());
                    //     msgResponse.setText(response.toString());
                    //  hideProgressDialog();
                }
            }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d(TAG, "Error: " + error.getMessage());
            // hideProgressDialog();
        }
    }) {

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

    jsonObjReq.setTag(TAG);
    // Adding request to request queue
    Volley.newRequestQueue(this).add(jsonObjReq);

}

现在我想以预期的json数组发送数据{"AppDb":"天","ContentTypeName":"用户","令牌":"U2FsdGVkX13CFEM=",过滤数据":[{"FilterName":"EmailId","FilterValue":"通过用户在此处输入电子邮件进行检查"}]

now i want to send data in array expected json { "AppDb":"day", "ContentTypeName":"Users", "Token":"U2FsdGVkX13CFEM=", "FilterData":[ {"FilterName":"EmailId","FilterValue":" Pass the user enter email here to check"} ]

}

推荐答案

试试这个:

JSONArray jsonArray=new JSONArray();
JSONObject jsonObj=new JSONObject();
try {
    jsonObj.put("filterName","EmailId");
    jsonObj.put("FilterValue",// user email);
} catch (JSONException e) {
    e.printStackTrace();
}
jsonArray.put(jsonObj);

像这样将其添加到您的参数中:

Add it to your params like this:

postParam.put("FilterData",jsonArray);
