[자바네트워크강좌, JAVA NETWORK]URL이란, 자바 URL 클래스

[자바네트워크강좌, JAVA NETWORK]URL이란, 자바 URL 클래스

Uniform Resource Locator의 약어가 URL이다. 즉 인터넷상의 리소스의 위를 나타내는것이 URL이다.(reference (an address) to a resource on the Internet)
 
 
http : 프로토콜 식별자
www.oraclejavanew.kr : 호스트 네임
80 : 웹서비스의 포트
index.html : 찾고자 하는 파일 네임

URL 클래스의 생성자
 
new URL("http://www.onjprogramming.co.kr:80/");
new URL("http", "www.onjprogramming.co.kr", "/index.html");
new URL("http", "www.onjprogramming.co.kr", 80, "/newmain/index.html");

URL객체는 한번 만들면 어떠한 속성도 바꿀 수없는 write-once Object이다.
 
아래는 몇가지 URL클래스의 메소드 이다.
 
public String getProtocol() : Returns the protocol identifier component of the URL.
public String getHost() : Returns the host name of the URL.
public int getPort() : Returns the port number component of the URL.
public String getFile(): Returns the filename of the URL.
public Object getContent() : Gets the contents of this URL
public Object getContent(Class[] classes) : Gets the contents of this URL
 
매개변수로 들어온 class의 인스턴스로 만들어진 자바의 URL 객체 컨텐츠를 반환한다. 클래스가 지원되지 않는 경우는  null 반환한다.
이 메소드를 호출한 쪽에서 어떻게 content를 인코딩 할지를 조절 할 수 있다. 예를들면 현재의 URL은 HTML 웹페이지의 인코딩을 String, HTML객체, InputStream  타입으로 수행할 수 있도록 지원하고 있는데 이때 URL 리소스를 문자열로 인코딩하여 받고 싶다면 이 메소드에 String.class를 넘기면 되고 , 스트림으로 인코딩 하여 받고 싶다면 InputStream.class를 넘기면 된다. 즉 이 메소드는 주어진 URL에서 여러가지 컨텐트 인코딩을 지원하는 경우에 쓸모가 있다. public Object getContent() 의 경우 반환되는 content의 type은 해당 컨텐츠에 달려 있다. 만약 URL이 어떤 이미지를 가리키고 있다면 반환되는 타입은 Image 가 될것이다.

public final InputStream openStream() throws IOException
Opens a connection to this URL and returns an InputStream for reading from that connection.
This method is a shorthand for openConnection().getInputStream()
public URLConnection openConnection()  throws IOException
Returns a URLConnection object that represents a connection to the remote object referred to by the URL.

A new connection is opened every time by calling the openConnection method of the protocol handler for this URL.
 
[예제]
 
import java.io.*;
import java.net.*;
class URLTest{
 public static void main(String[] args) throws Exception {
    try{  
  //URL aURL = new URL("http://www.daum.net");
  URL aURL = new URL("http", "www.onjprogramming.co.kr", 80 , "/onj/main/main.html");
  System.out.println("protocol name:" + aURL.getProtocol());
  System.out.println("host name:" + aURL.getHost());
  System.out.println("file name:" + aURL.getFile());
  //생성자에서 port가 set되는 경우에 표시, 아니면 -1
  System.out.println("port name:" + aURL.getPort());
  //HTML 문서 내부의 위치를 지정하는 <a name="..."> 태그의 값을 구한다.
  System.out.println("ref : "+aURL.getRef());
  BufferedReader br  = new BufferedReader(new    InputStreamReader(aURL.openStream()));
  String line;
  while((line = br.readLine()) != null) {
   System.out.println(line);
  }
 }
 catch(MalformedURLException e) {
  System.out.println("MalformedURLException : "+e);
 }
 catch(IOException e) {
  System.out.println("IOException :"+ e);
 }
}
}
 

[결과]
 
protocol name:http
host name:www.onjprogramming.co.kr
file name:/onj/main/main.html
port name:80
ref : null
