android如何发送int和double作为namevaluepair作为http post

Question

我有一个应用程序,我试图使用http帖子将数据发送到Web服务.用户数据是字符串int和double的混合.在应用程序中,所有都表示为字符串,因为当我使用AsyncTask来运行网络调用时(因此它不在主线程上),params数组是String类型.

我遇到的问题是服务器有时需要一个int.例如,compID是服务器期望的int.使用http帖子时,我使用NameValuePair.这只会接受字符串.如何将int或double传递给http帖子？

在我的活动中.

String[] params = new String[]{tagCompany, tagId, tagPerson, OUT,
                                null, null,null, null, null, null}; 
                        AsyncPostData apd = new AsyncPostData();
                        apd.execute(params);





private class AsyncPostData extends AsyncTask<String, Void, Void> {

        ProgressDialog progressDialog;

        @Override
        protected void onPreExecute()
        {
            progressDialog= ProgressDialog.show(NfcscannerActivity.this, 
                    "Connecting to Server"," Posting data...", true);            
        };  


        @Override
        protected Void doInBackground(String... params) {

            nfcscannerapplication.loginWebservice.postData(params[0], params[1], params[2], params[3], params[4],
                    params[5], params[6], params[7], params[8], params[9]);
            return null;
        }

         @Override
            protected void onPostExecute(Void result)
            {
             super.onPostExecute(result);
                if(progressDialog != null)
                progressDialog.dismiss();

            }
    }//end of AsyncPostData 

.

我的帖子方法

public void postData( String compID, String tagID, String clientID, String carerID, 
            String phoneScanned, String phoneSent, String TXType, String phoneType, String latitude, String longitude) {
        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://cfweb.yourofficeanywhere.co.uk:88/roadrunner.asmx/PostTransaction");


        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("CompanyID", compID));
            nameValuePairs.add(new BasicNameValuePair("TagID", tagID));
            nameValuePairs.add(new BasicNameValuePair("ClientID", clientID));
            nameValuePairs.add(new BasicNameValuePair("CarerID", carerID));
            nameValuePairs.add(new BasicNameValuePair("PhoneScanned", "2010-10-16 16:30 000"));
            nameValuePairs.add(new BasicNameValuePair("PhoneSent", "2010-10-16 16:32 000"));
            nameValuePairs.add(new BasicNameValuePair("TXType", "2"));
            nameValuePairs.add(new BasicNameValuePair("PhoneType", "2"));
            nameValuePairs.add(new BasicNameValuePair("Latitude", latitude));
            nameValuePairs.add(new BasicNameValuePair("Longitude", longitude));

            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

            Log.e(TAG, "response of post = " + response.toString());



        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }
    } 

在我的post方法中,一些值现在设置为null.我想知道的是如何在NameValuePair中使compID成为一个int.compID作为String来自活动,但服务器需要int.

Answer 1

你可以这样做:

nameValuePairs.add(new BasicNameValuePair("TXType",Integer.toString (2)));

TxType是键,2是值
