私はAndroidプログラミングに不慣れで、このWebサービスを呼び出し、値を渡し、xmlの形式でリターンを取得するアプリを開発しようとしていますが、リクエストを行うたびに、データエントリが無効であるためリターンを取得します。Http get And Postを試してみましたが、どちらも問題はありません。URLは次のとおりです。
http://hiscentral.cuahsi.org/webservices/hiscentral.asmx?op=GetSeriesCatalogForBox2
コードは、
HttpGet:
public class Main extends Activity implements OnClickListener
{
String xml=null;
String responseBody;
String text = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.my_button).setOnClickListener(this);
}
public void onClick(View arg0)
{
Button b = (Button)findViewById(R.id.my_button);
b.setClickable(false);
new LongRunningGetIO().execute();
}
private class LongRunningGetIO extends AsyncTask <Void, Void, String>
{
@Override
protected String doInBackground(Void... params)
{
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://hiscentral.cuahsi.org/webservices/hiscentral.asmx/GetSeriesCatalogForBox2?xmin=-100 &xmax=-90 &ymin=40 &ymax=55 &conceptKeyword=precipitation &beginDate=1/1/2009&endDate=1/1/2010 HTTP/1.1");
HttpResponse response = httpclient.execute(httpGet, localContext);
HttpEntity entity = response.getEntity();
text = getASCIIContentFromEntity(entity);
}
catch (Exception e)
{
return e.getLocalizedMessage();
}
return text;
}
catch (ClientProtocolException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
}
catch (UnsupportedEncodingException e)
{
e.printStackTrace();
}
return responseBody;
}
protected void onPostExecute(String results)
{
if (results!=null)
{
EditText et = (EditText)findViewById(R.id.my_edit);
et.setText(results);
}
Button b = (Button)findViewById(R.id.my_button);
b.setClickable(true);
}
}
}
HttpPostは、
HttpPost
public class Main extends Activity implements OnClickListener
{
String xml=null;
String responseBody;
String text = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViewById(R.id.my_button).setOnClickListener(this);
}
public void onClick(View arg0)
{
Button b = (Button)findViewById(R.id.my_button);
b.setClickable(false);
new LongRunningGetIO().execute();
}
private class LongRunningGetIO extends AsyncTask <Void, Void, String>
{
@Override
protected String doInBackground(Void... params)
{
HttpClient httpclient = new DefaultHttpClient();
String Url = "http://hiscentral.cuahsi.org/webservices/hiscentral.asmx?op=GetSeriesCatalogForBox2";
if(!Url.endsWith("?"))
{
Url += "?";
}
HttpPost httppost = new HttpPost(Url);
// Add data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(5);
nameValuePairs.add(new BasicNameValuePair("xmin", "-100"));
nameValuePairs.add(new BasicNameValuePair("xmax", "-90"));
nameValuePairs.add(new BasicNameValuePair("ymin", "40"));
nameValuePairs.add(new BasicNameValuePair("ymax", "55"));
nameValuePairs.add(new BasicNameValuePair("networkIDs", ""));
nameValuePairs.add(new BasicNameValuePair("conceptKeyword", "precipitation"));
nameValuePairs.add(new BasicNameValuePair("beginDate", "1/1/2009"));
nameValuePairs.add(new BasicNameValuePair("endDate", "1/1/2010"));
try
{
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Log.d("myapp", "works till here. 2");
HttpResponse response = httpclient.execute(httppost);
responseBody = EntityUtils.toString(response.getEntity());
// Log.d("myapp", "response " + response.getEntity());
// HttpEntity entity = response.getEntity();
// xml = getASCIIContentFromEntity(entity);
}
catch (Exception e)
{
return e.getLocalizedMessage();
}
return responseBody;
}
protected void onPostExecute(String results)
{
if (results!=null)
{
EditText et = (EditText)findViewById(R.id.my_edit);
et.setText(results);
}
Button b = (Button)findViewById(R.id.my_button);
b.setClickable(true);
}
}
}
助けてください ！！よろしくお願いします。
