한 줄을 읽는데 문제가 있습니다. 한 줄의 서버 응답을 가져와야합니다. 그러면 등록이 실패하면 모든 요청이 잘 수행되지 않습니다. 여기에 요청 후 서버에서 응답을받는 코드 조각이 있습니다.서버에서 응답 한 줄만 얻는 방법 android

DefaultHttpClient client = new DefaultHttpClient(); 
      HttpPost post = new HttpPost(
        "http://guiddy.fosslabs.ru/users/sign_in"); 
      post.setEntity(new UrlEncodedFormEntity(pairs)); 
      response = client.execute(post); 
      String responseStr = EntityUtils.toString(response.getEntity()); 

      Log.d("POST", "Response " + responseStr);

그리고 거기에 내 대답 :

이 문제에 대한 해결책을 발견 나는 Jsoup을 사용했다. I는 다음과 같은 예를 수신 :

String str3 = null; 
Document doc = Jsoup.parse(responseStr); 
Elements elems = doc.select("div"); 
for (Element elem : elems) { 
    if (elem.attr("class").equals("alert alert-alert")) { 
     str3 = elem.text(); 
    } 
} 
Log.d("POST", "Response " + responseStr); 
Log.d("POST2", "Response " + str3); 
Log.d("POST1", "Response " 
+ response.getStatusLine().toString());

그런 다음 데이터 처리를 수행
