Question

我正在尝试将数据从sqlite发送到服务器作为json对象。它正在捕获数据，但只有一个数据（行）进入服务器。

我的json代码是

JSONObject jobj = new JSONObject();


 if (c.moveToFirst()) {
        do {
            jobj.put("add_fld1", "Test1");
            jobj.put("add_fld2", "Test2");
            jobj.put("add_fld3", "Test3");

            jobj.put("credated_dt", c.getString(6));
            // jobj.put("id", c.getInt(0));

            jobj.put("emp_code", c.getString(5));
            jobj.put("location", c.getString(3));

            jobj.put("name", c.getString(1));

            jobj.put("phone", c.getString(2));
            jobj.put("remarrks", c.getString(4));

        }
        while (c.moveToNext());
    }

         return jobj.toString();
    }

更新

JsonArray正在运行，但服务器现在没有显示数据。

JsonArray代码

    private String getQuery() throws UnsupportedEncodingException, JSONException {

    Cursor c = sqLiteHelper.getData("SELECT * FROM DETAILS");
    JSONObject jobj = new JSONObject();
    JSONArray jsonArray = new JSONArray();

        while (c.moveToNext()) {


            jobj.put("add_fld1", "Test1");
            jobj.put("add_fld2", "Test2");
            jobj.put("add_fld3", "Test3");

            jobj.put("credated_dt", c.getString(6));
            // jobj.put("id", c.getInt(0));

            jobj.put("emp_code", c.getString(5));
            jobj.put("location", c.getString(3));

            jobj.put("name", c.getString(1));

            jobj.put("phone", c.getString(2));
            jobj.put("remarrks", c.getString(4));
            jsonArray.put(jobj);


        }


    return jsonArray.toString();

}

Json Array正在捕获所有数据并且响应成功但服务器没有显示JsonArray数据，但它显示了jsonobject数据。

您应该制作一个arraylist并将所有数据放入其中并将数据发送到服务器

JSONObject jobj = new JSONObject();

ArrayList<JSONObject> arrayList=new ArrayList();
 if (c.moveToFirst()) {
        do {
            jobj.put("add_fld1", "Test1");
            jobj.put("add_fld2", "Test2");
            jobj.put("add_fld3", "Test3");

            jobj.put("credated_dt", c.getString(6));
            // jobj.put("id", c.getInt(0));

            jobj.put("emp_code", c.getString(5));
            jobj.put("location", c.getString(3));

            jobj.put("name", c.getString(1));

            jobj.put("phone", c.getString(2));
            jobj.put("remarrks", c.getString(4));
           arrayList.add(jobj);
        }
        while (c.moveToNext());
    }

         return arrayList;
    }

现在你可以从这个arraylist获得所有记录。它帮帮我，请检查一下。

您应该创建一个JSONArray并将所有数据放入其中并将数据发送到服务器

JSONArray jsonArray = new JSONArray();

    if (c.moveToFirst()) {
        do {
            JSONObject jobj= new JSONObject();
            jobj.put("add_fld1", "Test1");
            jobj.put("add_fld2", "Test2");
            jobj.put("add_fld3", "Test3");

            jobj.put("credated_dt", c.getString(6));
            // jobj.put("id", c.getInt(0));

            jobj.put("emp_code", c.getString(5));
            jobj.put("location", c.getString(3));

            jobj.put("name", c.getString(1));

            jobj.put("phone", c.getString(2));
            jobj.put("remarrks", c.getString(4));
            jsonArray.put(jobj);

        }
        while (c.moveToNext());
    }

    return jsonArray.toString();
}

<强>解决方案：

再次将JSONArray转换为JSONObject并逐个发送它解决了我的问题

 protected String doInBackground(String... params) {
 boolean flag = false;


        try {
            URL url = new URL();
            JSONArray ja = getQuery();
            for (int i = 0; i < ja.length(); i++) {
                JSONObject jj = ja.getJSONObject(i);
                HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
                httpURLConnection.setDoInput(true);
                httpURLConnection.setDoOutput(true);
                httpURLConnection.setRequestProperty("Accept", "application/json");
                httpURLConnection.setRequestProperty("Content-type", "application/json");
                httpURLConnection.setRequestMethod("POST");

                outputStream = httpURLConnection.getOutputStream();
                BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream));
                bufferedWriter.write(jj.toString());
                Log.e("posted", "" + jj);
                Log.e("doInBackground", "postDataParams");
                bufferedWriter.flush();
                bufferedWriter.close();
                int statusCode = httpURLConnection.getResponseCode();
                Log.d("this", " The status code is " + statusCode);
                if (statusCode == 200) {
                    inputStream = new BufferedInputStream(httpURLConnection.getInputStream());
                    flag =true;
                }
                inputStream.close();
                outputStream.close();
                httpURLConnection.disconnect();
            }
        } catch (Exception e) {
            Log.e("streams1", "The response is " + e.getLocalizedMessage());
        } finally {
          Log.e("Delete", "Going to delete");
          sqLiteHelper.deleteAll();
        }
        if(flag)
                return "success";
        return null;
    }

只有一行通过JSON发布到服务器
