verycd下载套路,

发现一个downloads.txt文件同步正在下载的资源信息,下载完成后自动删除里面的记录,

思路:读downloads.txt文件,利用关键字把里面的记录分割后加入list,选择监视的文件名,利用while循环的倒计时方法以文件名为关键字从list里定时搜索,如果下载完成,调用runtime类运行dos命令shutdown,执行关机.

代码如下:

import java.io.BufferedReader;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.UnsupportedEncodingException;

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;

import java.util.Scanner;

// easyMule下downloads.txt文件的路径

public static final String FILEPATH = “D:\\Program Files\\easyMule\\downloads.txt”;

// 查找下载记录数的关键字

public static final String KEYWORD = “ed2k://|file|”;

// 刷新读入downloads.txt的时间(秒)

int second = 5;

// 下载完成后关机的延迟时间(秒)

int times = 60;

// 需要监视的文件id号

int id;

// 监视的文件名称

String fileName;

public ShutDown() {

System.out.println(“当前的下载文件信息为:”);

System.out

.println(“————————————————————–”);

showFile(readText(FILEPATH, KEYWORD));

System.out

.println(“————————————————————–”);

System.out.println(“要等哪个文件下载完成关闭计算机?”);

Scanner scan = new Scanner(System.in);

id = scan.nextInt() – 1;

fileName = (String) readText(FILEPATH, KEYWORD).get(id);

System.out.println(“监视的文件是:” + fileName);

while (countDown(second)) {

if (readText(FILEPATH, fileName).size() == 0) {

shutDownComputer(times);

System.out.println(“计算机将在” + times + “秒内关闭”);

unShutDownComputer();

}

break;

}

}

}

// 利用线程休眠进行倒计时

// 读取文件,查找下载的条目,返回List集合

} catch (IOException e) {

} finally {

try {

return list;

}

// 查看当前下载的记录数

public void showFile(List list) {

Iterator iter = list.iterator();

int count = 1;

while (iter.hasNext()) {

System.out.println(count + “=>” + iter.next());

count++;
