Post webservice在Android中不工作

-1

我是Android新手，還有webservices。我從來沒有使用過發佈web服務。嘗試如下，但它既不顯示成功也不失敗。Post webservice在Android中不工作

如果我使用高級rest客戶端chrome擴展，我能夠測試和webservice完美地工作，只是它需要很多時間。

當試圖從代碼運行時，它立即顯示 - 在調用webservices之後 - toast msg - >表示它沒有調用web服務。

花了2天，但沒有運氣。有什麼建議麼？

public void borrowBook(String barCode, String patronId) 
    { 
     final int DEFAULT_TIMEOUT = 200000 * 1000000000; 

     // Make RESTful webservice call using AsyncHttpClient object 
     AsyncHttpClient client = new AsyncHttpClient(); 
     client.setTimeout(DEFAULT_TIMEOUT); 

     progress.setMessage("Please Wait..."); 
     progress.setIndeterminate(false); 
     progress.setCancelable(false); 
     progress.show(); 

     RequestParams params = new RequestParams(); 

     Toast.makeText(getActivity().getApplicationContext(), "B4 calling webservice", Toast.LENGTH_LONG).show(); 

     client.post("http://43.555.6.111:8081/SIPServices/SIc.svc/Checkout?barcode=B12&patron=thi", new TextHttpResponseHandler() { 
        @Override 
        public void onSuccess(int i, Header[] headers, String response) { 
         Toast.makeText(getActivity().getApplicationContext(), "Response: " + response, Toast.LENGTH_LONG).show(); 
         Log.d("TAG", "Success"); 
        } 

        @Override 
        public void onFailure(int statusCode, Header[] headers, String response, Throwable error) { 
         Toast.makeText(getActivity().getApplicationContext(), "Status code :" + statusCode + "errmsg : " + error.getMessage(), Toast.LENGTH_LONG).show(); 
         Toast.makeText(getActivity().getApplicationContext(), "Unexpected Error occcured! [Most common Error: Device might not be connected to Internet or remote server is not up and running]", Toast.LENGTH_LONG).show(); 
         Log.d("TAG", "Failure"); 
        } 

       } 
     ); 
     progress.dismiss(); 
     Toast.makeText(getActivity().getApplicationContext(), "After calling webservice", Toast.LENGTH_LONG).show(); 
    }

您不會將參數設置爲任何值，也不會發送它們。另外，你正在嘗試做一個post調用，但URL是與獲取參數：「http://43.555.6.111:8081/SIPServices/SIc.svc/Checkout?barcode=B12&patron=thi」

也考慮實施onStart方法並記錄它，看看它是否開始。

我試着分別傳遞參數，但仍然無法正常工作。 client.post（「http://43.555.6.222:8091/Sices/SIc.svc/Checkout」，params，new TextHttpResponseHandler（）{ – Dep

）也歡迎任何其他建議。 – Dep

這是我的自定義類來處理請求。我在這裏使用json，你可以返回並鍵入你想要的。所有你需要的是

網址：http://43.555.6.111:8081/SIPServices/SIc.svc/Checkout
方法：「POST」

PARAMS：鍵和值的ArrayList：條碼= B12 &靠山= THI

HashMap<String, String> mValueParams = new HashMap<>(); 
mValueParams.put("barcode", "B12"); 
mValueParams.put("patron", "thi"); 

JSONObject json = jsonParser.makeHttpRequest(url, "POST",mValueParams);

公衆的JSONObject makeHttpRequest（String url，String method， HashMap params）{

sbParams = new StringBuilder(); 
    int i = 0; 
    for (String key : params.keySet()) { 
     try { 
      if (i != 0) { 
       sbParams.append("&"); 
      } 
      sbParams.append(key).append("=") 
        .append(URLEncoder.encode(params.get(key), charset)); 

     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     } 
     i++; 
    } 

    if (method.equals("POST")) { 
     // request method is POST 
     try { 
      urlObj = new URL(url); 

      conn = (HttpURLConnection) urlObj.openConnection(); 

      conn.setDoOutput(true); 

      conn.setRequestMethod("POST"); 

      conn.setRequestProperty("Accept-Charset", charset); 

      conn.setReadTimeout(10000); 
      conn.setConnectTimeout(15000); 

      conn.connect(); 

      paramsString = sbParams.toString(); 

      wr = new DataOutputStream(conn.getOutputStream()); 
      wr.writeBytes(paramsString); 
      wr.flush(); 
      wr.close(); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } else if (method.equals("GET")) { 
     // request method is GET 

     if (sbParams.length() != 0) { 
      url += "?" + sbParams.toString(); 
     } 

     try { 
      urlObj = new URL(url); 

      conn = (HttpURLConnection) urlObj.openConnection(); 

      conn.setDoOutput(false); 

      conn.setRequestMethod("GET"); 

      conn.setRequestProperty("Accept-Charset", charset); 

      conn.setConnectTimeout(15000); 

      conn.connect(); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

    } 

    try { 
     //Receive the response from the server 
     int status = conn.getResponseCode(); 
     InputStream in = new BufferedInputStream(conn.getInputStream()); 
     BufferedReader reader = new BufferedReader(new InputStreamReader(in, "iso-8859-1"), 8); 
     result = new StringBuilder(); 
     String line; 
     while ((line = reader.readLine()) != null) { 
      result.append(line); 
     } 

    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    conn.disconnect(); 

    // try parse the string to a JSON object 
    try { 
     jObj = new JSONObject(result.toString()); 
    } catch (Exception e) { 
     Log.e("JSON Parser", "Error parsing data " + e.toString()); 
    } 

    // return JSON Object 
    return jObj; 
}
