[color=red][size=large]下面是我的代码,如果url当中没有中文则可以下载,如果有则出错。InputStream in = con.getInputStream();这一句出错。
这个是编码问题,我上网找了很多资料,但是还是不会改,对编码的原理还不是很了解。哪位帮忙改改,谢谢![/size][/color]
[code="java"]import java.io.File;
import java.io.FileOutputStream;

public static void DownloadFile(URL theURL, String filePath) throws IOException {
URLConnection con = theURL.openConnection();
String urlPath = con.getURL().getFile();
String fileFullName = urlPath.substring(urlPath.lastIndexOf("/") + 1);
if (fileFullName != null) {
byte[] buffer = new byte[4 * 1024];
int read;
String path = filePath + "/" + fileFullName;
File fileFolder = new File(filePath);
if(!fileFolder.exists()){
fileFolder.mkdir();
}
InputStream in = con.getInputStream();
FileOutputStream os = new FileOutputStream(path);
while ((read = in.read(buffer)) > 0) {
os.write(buffer, 0, read);
}
os.close();
in.close();
long end = System.currentTimeMillis();
