HttpClient HTTP POST로 String 받는 두 가지 방법

HttpEntity를 받아와서 바로 EntityUtils를 사용하여 String으로 바로 뽑아내는 것은

아래 코드로 가능하지만

 
   DefaultHttpClient httpClient = new DefaultHttpClient(); 
  HttpPost httpPost = new HttpPost("http://hako.04p.kr/"); 
  List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
  nameValuePairs.add(new BasicNameValuePair("parameter1", "11"));
  nameValuePairs.add(new BasicNameValuePair("parameter2", "22"));
  httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
 
  HttpResponse httpResponse = httpClient.execute(httpPost);
  HttpEntity httpEntity = httpResponse.getEntity(); 
  String resultString = EntityUtils.toString(httpEntity);
 
 

InputStream으로 받아서 String으로 바꿔야 할 경우는 아래 코드를 사용한다.

 
  DefaultHttpClient httpClient = new DefaultHttpClient(); 
  HttpPost httpPost = new HttpPost("http://hako.04p.kr/"); 
  List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
  nameValuePairs.add(new BasicNameValuePair("parameter1", "11"));
  nameValuePairs.add(new BasicNameValuePair("parameter2", "22"));
  httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
  HttpResponse httpResponse = httpClient.execute(httpPost);
  HttpEntity httpEntity = httpResponse.getEntity();
  InputStream inputStream = httpEntity.getContent(); 
  ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
 
  while (true) { 
           byte[] temp = new byte[8 * 1024]; 
           int readLength = inputStream.read(temp); 
           if (readLength < 0) 
                   break; 
 
           byteArrayOutputStream.write(temp, 0, readLength);
  }
 
  inputStream.close(); 
  byte[] buffer = new byte[1024 * 1024];
  buffer = byteArrayOutputStream.toByteArray();
  String resultString = new String(buffer);
