Download file from URL

I have thought of this idea for a while. Is it actually possible to download a file from somewhere. Example: I write in console "download www.example.com/example.random random/directory/here/" and the plugin will download a file from site "www.example.com/example.random" and save it to directory "random/directory/here/"

Thanks in advance!

 

well, i just used google and found this that i thought you might find useful.

in other words, yes it is possible

 

Im quite a newbie so dont shout on me...
I made this script but for some reason when i run a command: "download example.jpg http://upload.wikimedia.org/wikipedia/en/8/87/Example.JPG plugins" the server just stops (It can be any file, that was just an example)

Code:

Code:

package com.vilsol.downurl;
 
import java.io.*;
import java.net.*;
import java.util.logging.Logger;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.plugin.java.JavaPlugin;
 
public class DownURL extends JavaPlugin {
 
    public static DownURL plugin;
 
    public final Logger logger = Logger.getLogger("Minecraft");
 
    public void onEnable(){
        this.logger.info("DownURL Enabled!");
    }
 
    public void onDisable(){
        this.logger.info("DownURL Disabled!");
    }
 
 
    public void saveUrl(String filename, String urlString, String directory) throws MalformedURLException, IOException
    {
        BufferedInputStream in = null;
        FileOutputStream fout = null;
        try
        {
                in = new BufferedInputStream(new URL(urlString).openStream());
                fout = new FileOutputStream(directory + "\\" + filename);
 
                byte data[] = new byte[1024];
                int count;
                while ((count = in.read(data, 0, 1024)) != -1)
                {
                        fout.write(data, 0, count);
                }
        }
        finally
        {
                if (in != null)
                        in.close();
                if (fout != null)
                        fout.close();
        }
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        if(commandLabel.equalsIgnoreCase("download")){
            try {
                saveUrl(args[1], args[2], args[3]);
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } 
            return true;
        }else{
            return false;
        }
    }
 
    public static String[] RearangeString(int startIndex, String[] string)
      {
        String TMPString = "";
        for (int i = startIndex; i < string.length; i++) {
          String Add = " ";
          if (i == startIndex) {
            Add = "";
          }
          TMPString = TMPString + Add + string[i];
        }
        return TMPString.split("\\ ");
      }
}

 

one thing to note is that the file will be downloaded onto the server, not the client!

Working code that dosent stop the server

Code:

package test;
 
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URL;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin implements Runnable {
 
    URL file;
    File dest = new File("plugins/stuff");
 
    public void onEnable() {
 
    }
 
    public void onDisable() {
 
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        try {
            file = new URL(args[0]);
            Thread th = new Thread(this);
            th.start();
            return true;
        } catch (Exception e) {
            e.printStackTrace();
        }
    return false;
    }
 
    @Override
    public void run() {
        download(file, dest);
    }
 
    public void download(URL file, File dest) {
        try {
            InputStream is = file.openStream();
            File finaldest = new File(dest + "/" + file.getFile());
            finaldest.getParentFile().mkdirs();
            finaldest.createNewFile();
            OutputStream os = new FileOutputStream(finaldest);
            byte data[] = new byte[1024];
            int count;
            while ((count = is.read(data, 0, 1024)) != -1) {
                os.write(data, 0, count);
            }
            os.flush();
            is.close();
            os.close();
        } catch (Exception ec) {
            ec.printStackTrace();
        }
    }
}

note: could most likely be improved

 

Love you
