사용자 이름과 암호를 인수로 사용해야하는 authenticate라는 함수를 만들려고합니다. 이 함수는 새로운 스레드를 만들고 데이터를 .php 파일에 게시하고 인증 결과를 반환합니다. 내가 직면하고있는 문제는 IOException이 발생하고 이유를 파악할 수 없다는 것입니다. 관련 기능과 LogCat을 여기에서 공유하고 있습니다. 어떤 도움을 주시면 감사하겠습니다.IOException! Connection refused
을 인증 기능 :
private boolean authenticate (final String userName, final String password) throws ClientProtocolException, IOException, InterruptedException {
Thread httpThread = new Thread (new Runnable() {
@Override
public void run() {
HttpClient client = new DefaultHttpClient();
HttpPost postHandle = new HttpPost (projectFolder + "appSupport/appBackEnd.php");
Log.d ("Connection",projectFolder + "appSupport/appBackEnd.php");
List <NameValuePair> credentials = new ArrayList <NameValuePair>();
credentials.add (new BasicNameValuePair ("action", "authenticate"));
credentials.add (new BasicNameValuePair ("username", userName));
credentials.add (new BasicNameValuePair ("password", password));
try {
postHandle.setEntity(new UrlEncodedFormEntity(credentials));
Log.d ("Connection", "Entity Set!");
HttpResponse response = client.execute(postHandle);
Log.d ("Connection", "Executed!");
String res = response.getEntity().toString();
Log.d ("Connection", "Response" + res);
if (res.equals("1"))
result = true; // result is a global variable
else
result = false;
}
catch (UnsupportedEncodingException e) {
Log.d ("Connection", "Exception! UnsupportedEncodingException");
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
Log.d ("Connection", "Exception! ClientProtocolException");
e.printStackTrace();
} catch (IOException e) {
Log.d ("Connection", "Exception! IOException");
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
httpThread.start();
httpThread.join();
return result;
}
