Question

我正在尝试将jsonArray发布到php服务器但是在发布org.json.JSONArray时收到错误无法转换为JSON对象

请让我知道这个问题

JSONArray jArr = SubstationDb.getResults（）; Ë JSONObject postDataParams = new JSONObject（jArr.toString（））;

        JSONArray data = postDataParams.getJSONArray("");
        for(int i=0;i<=jArr.length();i++)
        {
            JSONObject c = data.getJSONObject(i);

           postDataParams.putOpt("did",c.getString("did"));
            postDataParams.put("bid",c.getString("bid"));
            postDataParams.put("vid", c.getString("vid"));
            postDataParams.put("substn_name", c.getString("substn_name"));
            postDataParams.put("sub_height", c.getString("sub_height"));
            postDataParams.put("latitude", c.getString("latitude"));
            postDataParams.put("longitude", c.getString("longitude"));
            postDataParams.put("serial_number", c.getString("serial_number"));
            postDataParams.put("nickname", c.getString("nickname"));
            postDataParams.put("substn_pic", c.getString("substn_pic"));
            postDataParams.put("substn_status", c.getString("substn_status"));
            postDataParams.put("uploadedtime", c.getString("uploadedtime"));
            postDataParams.put("sid", c.getString("sid"));
        }

Answer 1

JSONArray postDataParams = new JSONArray();

首先创建一个postDataParams数组，然后将其推送到JSONObject并将其发送到后端。

我试图将jsonArray发布到php但是得到错误org.json.JsonArray无法转换
