傳遞的JSONObject到的AsyncTask然後使用HttpPost發送到PHP服務器

Question

做大量的研究，我一直沒能在傳遞JSONObject，然後檢索服務器端找到使用AsyncTask有人HttpPost一個JSONObject後。我正在填寫JSONObject通過多個HashMaps。

當我通過JSONObject到AsyncTask我得到了什麼看起來像JSONObject引用，從這一點，我不確定如何解析正確，PHP服務器端。

JSONObject構建器方法和AsyncTask呼叫者：

HashMap<Integer, HashMap<String, String>> finalHash; 
HashMap<String, String> semiFinalHash; 
private void completeSurvey() throws JSONException { 

    finalHash = new HashMap<Integer, HashMap<String, String>>(); 
    semiFinalHash = new HashMap<String, String>(); 

    JSONArray jArray = new JSONArray(); 
    JSONObject joMap = new JSONObject(); 
    for (int indexInt = 0; indexInt <= lightingMap.size(); indexInt++) { 
     if (lightingMap.containsKey(indexInt) && !placeholderHashMap.containsKey(indexInt)) { 
      int checkId = indexInt; 
      placeholderHashMap.put(checkId, "null"); 
     } 
    } 

    Log.i("", "" + placeholderHashMap.toString()); 
    for (int finalOutPut = 0; finalOutPut < lightingMap.size(); finalOutPut++) { 
     JSONObject jo = new JSONObject(); 
     try { 
      int id = finalOutPut + 1; 
      jo.put("id", id); 
      jo.put("SurveyPhoto", placeholderHashMap.get(id)); 
      jo.put("Lighting", lightingMap.get(id)); 
      jo.put("Notes", signSpecNotesMap.get(id)); 
      jo.put("AdditionalService", chkBxMap.get(id)); 
      //jo.put("Coordinates", latLngMap.get(id)); 
      jArray.put(jo); 

     } catch (Exception e) { 
      Log.e("", "" + e.getMessage()); 
     } 
    } 
    joMap.put(businessName, jArray); 
    Log.i("JSONObject", joMap.toString()); 
    new CompleteSurveyAsync().execute(joMap); 
} 

AsyncTask類別：

class CompleteSurveyAsync extends AsyncTask<JSONObject, Void, String> { 

    public ProgressDialog progressDialog = new ProgressDialog(Main.this); 

    protected void onPreExecute() { 
     progressDialog.setMessage("Submitting Data to Server..."); 
     progressDialog.show(); 
     progressDialog.setOnCancelListener(new OnCancelListener() { 
      public void onCancel(DialogInterface diaInterface) { 
       CompleteSurveyAsync.this.cancel(true); 
       diaInterface.dismiss(); 
      } 
     }); 
    } 

    String inString, parameterPass; 
    JSONObject jobject; 
    @Override 
    protected String doInBackground(JSONObject... jObject) { 

     parameterPass = jObject.toString(); 
     Log.i("doInBackground", parameterPass); 
     String url_select = "http://www.somewebsite.com/db/completedSurvey.php"; 
     HttpResponse response; 
     try { 

      HttpPost httpPost = new HttpPost(url_select); 
      HttpClient httpClient = new DefaultHttpClient(); 

      httpPost.setEntity(new ByteArrayEntity(jObject.toString().getBytes("UTF8"))); 
      httpPost.setHeader("Accept", "application/json"); 
      httpPost.setHeader("Content-type", "application/json"); 
      response = (HttpResponse) httpClient.execute(httpPost); 

      HttpEntity entity = response.getEntity(); 

      if(entity != null) { 
       InputStream in = response.getEntity().getContent(); 
       inString = in.toString(); 
       Log.i("InputStream", "" + in.toString()); 
      } 

     } catch (UnsupportedEncodingException e1) { 
      Log.e("UnsupportedEncodingException", e1.toString()); 
      e1.printStackTrace(); 
     } catch (ClientProtocolException e2) { 
      Log.e("ClientProtocolException", e2.toString()); 
      e2.printStackTrace(); 
     } catch (IllegalStateException e3) { 
      Log.e("IllegalStateException", e3.toString()); 
      e3.printStackTrace(); 
     } catch (IOException e4) { 
      Log.e("IOException", e4.toString()); 
      e4.printStackTrace(); 
     } 
     return parameterPass; 
    } 

    protected void onPostExecute(String s) { 
     this.progressDialog.dismiss(); 
     Log.i("onPostExecute", s); 
     Toast.makeText(Main.this, s, Toast.LENGTH_LONG).show(); 
    } 

}

這使我的logcat的輸出：

11-13 09:52:45.606: I/JSONObject(2601): {"SOME COMPANY":[{"Notes":"null","SurveyPhoto":"[B@427a1fa8","id":1,"Lighting":1,"AdditionalService":0},{"Notes":"null","SurveyPhoto":"null","id":2,"Lighting":0,"AdditionalService":0},{"Notes":"null","SurveyPhoto":"null","id":3,"Lighting":1,"AdditionalService":0},{"Notes":"null","SurveyPhoto":"null","id":4,"Lighting":1,"AdditionalService":0}]} 
11-13 09:52:45.626: I/doInBackground(2601): [Lorg.json.JSONObject;@416ad478 
11-13 09:52:45.786: I/InputStream(2601): org.apache.http.conn.EofSensorInputStream@416c51d0 
11-13 09:52:45.816: I/onPostExecute(2601): [Lorg.json.JSONObject;@416ad478 

我驗證了JSON，構建它工作正常，但經過AsyncTask當我開始變得[Lorg.json.JSONObject;@4158c990，這是一個對象引用？如果是這樣，我該如何解析這個PHP服務器端？

我當前的PHP設置爲只寫入一個文件：

$json = file_get_contents('php://input'); 
$jsonObj = json_decode($json, true); 

$jsonFile = "json.txt"; 
$fh = fopen($jsonFile, 'a'); 

fwrite($fh, $json); 
fwrite($fh, "\n"); 
fwrite($fh, $jsonObj); 
fwrite($fh, "\n"); 

fclose($fh); 

輸出（json.txt）：

[Lorg.json.JSONObject;@416ad478 

Answer 1

JSONObject... jObject意味着jObject不是JSONObject ...它是一個可變參數/陣列

嘗試

if(jObject.length > 0) 
{ 
    final JSONObject realjObject = jObject[0]; 
    //rest of code goes here and instead of jObject we are using realjObject 
} 

編輯： 代替：

httpPost.setEntity(new ByteArrayEntity(jObject.toString().getBytes("UTF8"))); 

使用（只是爲了乾淨的代碼:)）：

httpPost.setEntity(new StringEntity(jObject.toString(), "UTF8"));
