發送JSON數組對象作爲參數從Android

發送JSON數組對象PHP服務作爲參數從Android PHP服務我有一個JSON對象有許多字符串數據和jsonarray數據發送JSON數組對象作爲參數從Android

**ArrayList<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(); 
    HttpResponse httpResponse = null; 

    // Making HTTP request 
    try { 
     // defaultHttpClient 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     JSONArray product_array = null; 
     /* 
     * namevaluepair.add(new BasicNameValuePair("val1",val1)); 
     * namevaluepair.add(new BasicNameValuePair("val2",val2)); 
     */ 

     try { 
      nameValuePair = new ArrayList<NameValuePair>(); 
      nameValuePair.add(new BasicNameValuePair("n", jsonParams 
        .getString("n"))); 
      nameValuePair.add(new BasicNameValuePair("e", jsonParams 
        .getString("e"))); 
      nameValuePair.add(new BasicNameValuePair("p", jsonParams 
        .getString("p"))); 
      nameValuePair.add(new BasicNameValuePair("a", jsonParams 
        .getString("a"))); 
      nameValuePair.add(new BasicNameValuePair("t", jsonParams 
        .getString("t"))); 
      nameValuePair.add(new BasicNameValuePair("m", jsonParams 
        .getString("m"))); 
      product_array = jsonParams.getJSONArray("pj"); 
      Log.i(TAG + "PPPPJJJ", product_array.toString()); 
     // nameValuePair.add(new BasicNameValuePair("pj", product_array 
       // .toString())); 
     } catch (Exception e) { 
      Log.e(TAG, "2:" + e.getMessage()); 
     } 

     String enc_url = URLEncoder.encode(url); 
     HttpPost httpPost = new HttpPost(enc_url); 
     httpPost.addHeader("accept", "application/json"); 
     httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair)); 
     httpResponse = httpClient.execute(httpPost); 


    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    }**

但它不是轉發JSON數組到服務器，服務器的PHP文件是沒有收到該數組數據，但與瀏覽器工作正常因此，我認爲問題是在我的代碼。

執行代碼時出現以下錯誤。

你想將數據發送到服務器的數據庫？ –

試試這個 – WISHY

是啊，我正在裝盤這些數據發送到服務器 –

您可以使用droidQuery發送此很容易：

$.ajax(new AjaxOptions().url("http://www.example.com")//switch with real URL 
         .type("POST") 
         .dataType("json") 
         .data(jsonParams)//your JSON Object 
         .context(this) 
         .success(new Function() { 
          @Override 
          public void invoke($ droidQuery, Object... params) { 
           //if you are expecting a JSONObject: 
           JSONObject response = (JSONObject) params[0]; 
           //TODO: handle response 
          } 
         }) 
         .error(new Function() { 
          @Override 
          public void invoke($ droidQuery, Object... params) { 
           AjaxError error = (AjaxError) params[0]; 
           $.toast(error.status + ": " + error.reason, Toast.LENGTH_LONG); 
           //retry once 
           $.ajax(error.request, error.options.error($.noop())); 
          } 
         }));

這是我認爲它應該做的事：

URL url = new URL("//ip of your PHP function on your web server"); 
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); 
StringBuilder postDataBuilder = new StringBuilder(); 
postDataBuilder.append(URLEncoder.encode("005", "UTF-8")); 
urlConnection.setDoOutput(true); 
urlConnection.setRequestMethod("POST"); 
urlConnection.setUseCaches(false); 
urlConnection.setConnectTimeout(10000); 
urlConnection.setReadTimeout(10000); 
urlConnection.setRequestProperty("Content-Type","application/json"); 
urlConnection.connect(); 
JSONObject jsonParam = new JSONObject(); 
jsonParam.put("item 1", "value 1"); 
//Add other pairs here, as you are doing 
OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream()); 
out.write(jsonParam.toString()); 
out.close(); 
InputStream is = urlConnection.getInputStream(); 
BufferedReader br = new BufferedReader(new InputStreamReader(is)); 
String line; 
StringBuffer response = new StringBuffer(); 
while((line = br.readLine()) != null){ 
    response.append(line); 
    response.append('\n'); 
} 
if (urlConnection.getResponseCode() == HttpURLConnection.HTTP_OK) { 
System.out.println(response.toString()); 
} 
else {          
    System.out.println("Incorrect response code"); 
} 
br.close(); 
urlConnection.disconnect();

此代碼允許您使用InputStream和BufferedReader發送JSON對象，然後得到響應。希望這有幫助！

mattpic >我有很多其他的參數，只是字符串，只有一個參數我應該作爲json數組傳遞 –

現在它工作我解決了問題，String enc_url = URLEncoder.encode（url）; HttpPost httpPost = new HttpPost（enc_url）; httpPost.addHeader（「accept」，「application/json」）; –

我很高興我能幫上忙。如果這有助於您找到解決方案，請標記答案正確 – mattpic

JSONObject j = new JSONObject(); try { 
     j.put("n", jsonParams 
       .getString("n")); 
     j.put("e", jsonParams 
       .getString("e")); 
     j.put("p", jsonParams 
       .getString("p")); 
     j.put("e", jsonParams 
       .getString("p")); 
      j.put("a", jsonParams 
       .getString("a")); 
     j.put("t", jsonParams 
       .getString("t")); 
     j.put("m", jsonParams 
       .getString("m")); 
     product_array = jsonParams.getJSONArray("pj"); 
     Log.i(TAG + "PPPPJJJ", product_array.toString()); 

     j.put("array", product_array); 
    } catch (Exception e) { 
     Log.e(TAG, "2:" + e.getMessage()); 
    } 

    String enc_url = URLEncoder.encode(url); 
    HttpPost httpPost = new HttpPost(enc_url); 
    httpPost.addHeader("accept", "application/json"); 
    httpPost.setEntity(new UrlEncodedFormEntity(j)); 
    httpResponse = httpClient.execute(httpPost); 


} catch (UnsupportedEncodingException e) { 
    e.printStackTrace(); 
} catch (ClientProtocolException e) { 
    e.printStackTrace(); 
} catch (IOException e) { 
    e.printStackTrace(); 
}**
