如何通过http协议传送整个目录的文件？

Question

试试看，参数url中含文件名
public void downFile(String url) throws Exception {
URL m_Url=new java.net.URL(url);
HttpUrlConnection m_Hcon=(java.net.HttpURLConnection)m_Url.openConnection();
InputStream m_Is=m_Hcon.getInputStream();
java.io.BufferedReader br=new java.io.BufferedReader(new java.io.InputStreamReader(m_Is));
char[] buff=new char[1024];
int i=0;
java.io.File f=new java.io.File("c:\\out.temp");
f.createNewFile();
java.io.FileOutputStream fos=new java.io.FileOutputStream(f);
java.io.BufferedWriter bw=new java.io.BufferedWriter(new java.io.OutputStreamWriter(fos));
while((i=br.read(buff))!=-1){
bw.write(buff,0,i);
}
bw.close();
br.close();
}
