我有一个应用程序,我正在尝试使用 http 帖子将数据发送到网络服务。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 运行网络调用时(因此它不在主线程上),params 数组的类型为字符串。
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。这将只接受字符串。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
.
我的发帖方式
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 中将 compID 设为 int。compID 作为字符串来自活动,但服务器需要一个 int。
