众所周知,或者可能知道,MediaFire不允许直接下载链接,但您实际上必须单击“下载”按钮以生成引用该文件的随机链接。有没有办法获取该链接并下载它?
答案 0 :(得分:0)
在编写自动更新应用程序的绝望中,我编写了一个简短的Java应用程序,它允许从MediaFire下载文件。这是完整的代码:
import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
public class mainwindow {
/**
* Launch the application.
*/
static mainwindow thisInstance;
public static void main(String[] args) {
new mainwindow();
}
public mainwindow()
{
otherthread();
}
public void otherthread()
{
navigate("http://www.mediafire.com/download/aqtmhwvb8yvqclu/SmartSharePC.jar","downloadedFromMediafire");
// navigate("http://www.mediafire.com/download/j7e4wh6hbdhdj84/Minecraft+1.5.2-+C.H.T.zip","mediafire");
}
private void navigate(String url,String sufix)
{
try
{
String downloadLink = fetchDownloadLink(getUrlSource(url));
saveUrl(downloadLink,sufix);
} catch (Exception e)
{
e.printStackTrace();
}
}
public void saveUrl(final String urlString,String sufix) throws Exception
{
System.out.println("Downloading...");
String filename = urlString.substring(urlString.lastIndexOf("/")+1, urlString.lastIndexOf("."))+"_"+sufix+urlString.substring(urlString.lastIndexOf("."), urlString.length());
BufferedInputStream in = null;
FileOutputStream fout = null;
try {
in = new BufferedInputStream(new URL(urlString).openStream());
fout = new FileOutputStream(filename);
final 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();
}
}
System.out.println("Success!");
}
private static String getUrlSource(String url) throws IOException
{
System.out.println("Connecting...");
URL yahoo = new URL(url);
URLConnection yc = yahoo.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
yc.getInputStream(), "UTF-8"));
String inputLine;
String total="";
while ((inputLine = in.readLine()) != null)
total+=inputLine;
in.close();
return total;
}
private static String fetchDownloadLink(String str)
{
System.out.println("Fetching download link");
try {
String regex = "(?=\\<)|(?<=\\>)";
String data[] = str.split(regex);
String found = "NOTFOUND";
for (String dat : data) {
if (dat.contains("DLP_mOnDownload(this)")) {
found = dat;
break;
}
}
String wentthru = found.substring(found.indexOf("href=\"") + 6);
wentthru = wentthru.substring(0, wentthru.indexOf("\""));
return wentthru;
} catch (Exception e)
{
e.printStackTrace();
return "ERROR";
}
}
}
