C#
Not tested.
using System; using System.Net; using System.Text; class Program { static void Main() { string url = "http://www.rosettacode.org/"; WebClient wc = new WebClient(); byte[] data = wc.DownloadData(url); string content = Encoding.UTF8.GetString(data); Console.WriteLine(content); } }
Erlang
Synchronous
-module(main). -export([main/1]). main([Url|[]]) -> inets:start(), case http:request(Url) of {ok, {_V, _H, Body}} -> io:fwrite("~p~n",[Body]); {error, Res} -> io:fwrite("~p~n", Res) end.
Asynchronous
-module(main). -export([main/1]). main([Url|[]]) -> inets:start(), http:request(get, {Url, [] }, [], [{sync, false}]), receive {http, {_ReqId, Res}} -> io:fwrite("~p~n",[Res]); _Any -> io:fwrite("Error: ~p~n",[_Any]) after 10000 -> io:fwrite("Timed out.~n",[]) end.
Using it
|escript ./req.erl http://www.rosettacode.org
Java
<java>import java.net.URL; import java.io.*;
public class Main {
public static void main(String[] args) throws Exception { URL url = new URL("http://www.rosettacode.org"); InputStreamReader is = new InputStreamReader(url.openStream()); BufferedReader reader = new BufferedReader(is); String line = ""; while ( (line = reader.readLine()) != null) { System.out.println(line); } reader.close(); }
}</java>
Only works in Java 1.5/5.0+
<java>import java.util.Scanner; import java.net.URL;
public class Main {
public static void main(String[] args) throws Exception { URL url = new URL("http://www.rosettacode.org"); Scanner sc = new Scanner(url.openStream()); while( sc.hasNext() ) System.out.println(sc.nextLine()); }
}</java>
