E/JSON解析器：解析数据时出错[java.lang.Integer类型的值60无法转换为JSONObject] 60（97）

-1

我是android编程的新手。我有一个问题，当我试图从Android中使用JSON从MySQL数据库中获取数据。这是我的方法。这是我收到错误：类型的值60 java.lang.Integer中不能转换到的JSONObjectE/JSON解析器：解析数据时出错[java.lang.Integer类型的值60无法转换为JSONObject] 60（97）

private void getData(final String mac_Address){ 
    //Creating a string request 
    // Tag used to cancel the request 
    String tag_string_req = "req_monitor"; 
    StringRequest stringRequest = new StringRequest(Request.Method.POST, AppConfig.URL_MONITOR_HEALTH_PARAMETERS, 
      new Response.Listener<String>() { 
       @Override 
       public void onResponse(String response) { 
        JSONObject j = null; 
        try { 

         //Parsing the fetched Json String to JSON Object 
         j = new JSONObject(response); 
         //boolean error = j.getBoolean("error"); 

         //j = new JSONObject().append("userid", new JSONArray(json).getInt(0)); 
         //boolean error = j.getBoolean("error"); 
         //return new JSONObject(json.substring(json.indexOf("{"), json.lastIndexOf("}") + 1)); 

         //Storing the Array of JSON String to our JSON Array 
         result = j.getJSONArray("result"); 
         //new JSONObject().append("pulse_rate", new JSONArray(result).getInt(0)); 
         //JSONArray k = null; 
         for(int i=0;i<result.length();i++){ 
          try { 
           //Getting json object 
           JSONObject json = result.getJSONObject(i); 

           pulse_rate.add(json.getInt("pulse_rate")); 
           pulse_oxygen_saturation.add(json.getInt("pulse_oxygen_saturation")); 
           Log.d(TAG, "Fetching pulse rate from mysql: " +pulse_rate+" Fetching pulse rate from mysql: "+pulse_oxygen_saturation); 
          } catch (JSONException e) { 
           e.printStackTrace(); 
          } 
         } 

         //Calling method getMonitoringData to get the students from the JSON Array 
         // getMonitoringData(result); 
        } catch (JSONException e) { 
         e.printStackTrace(); 
         Log.e("JSON Parser", "Error parsing data [" + e.getMessage()+"] "+response); 
        } 
       } 
      }, 
      new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 

       } 

      }) 
    { 

     @Override 
     protected Map<String, String> getParams() { 
      // Posting parameters to monitor url 
      Map<String, String> params = new HashMap<String, String>(); 
      params.put("mac_Address", mac_Address); 
      return params; 
     } 

    }; 

    //Creating a request queue 
    //RequestQueue requestQueue = Volley.newRequestQueue(this); 

    // Adding request to request queue 
    AppController.getInstance().addToRequestQueue(stringRequest, tag_string_req); 

    //Adding request to the queue 
    //requestQueue.add(stringRequest); 

}

这是我的PHP代码

$query = "SELECT pulse_rate, pulse_oxygen_saturation from health_para"; 
if ($result = mysqli_query($link, $query)) { 

/* fetch associative array */ 
$result1 = array(); 
while ($row = mysqli_fetch_row($result)) { 
    printf ("%s (%s)\n", $row[0], $row[1]); 
array_push($result1,array(
    'pulse_rate'=>$row[0], 
    'pulse_oxygen_saturation'=>$row[1], 
)); 
    //$response[]=$row; 
    //echo json_encode($response); 
    echo json_encode(array('result'=>$result1)); 
} 

/* free result set */ 
mysqli_free_result($result); 
} 

/* close connection */ 
mysqli_close($link); 

    } else { 
// required post params is missing 
$response["error"] = TRUE; 
$response["error_msg"] = "Required parameters mac_address is missing!"; 
echo json_encode($response); 
}

这是在我的日志我的JSON响应：这是我的日志：

请张贴您的JSON响应。你的json响应和解析它的方式似乎有些不同。 –

{“result”：[{“pulse_rate”：“60”，“pulse_oxygen_saturation”：“97”}]} 60（97） {“result”：[{“pulse_rate”：“60”，“pulse_oxygen_saturation” “97”}，{“pulse_rate”：“60”，“pulse_oxygen_saturation”：“97”}]} 59（97） – hermeshabib

它看起来不像一个有效的JSON。请发布正确和有效的JSON响应。 –

试试这个。

pulse_rate.add(json.getString("pulse_rate")); 
          pulse_oxygen_saturation.add(json.getString("pulse_oxygen_saturation"));
