Socket如何传送多个文件？？
我写了一个传送多个文件的程序，可结果却是把多个文件都写在一个文件里去了，请问如何把文件分开来写入？？主要代码如下：
server:
程序代码： public void run() {
try {
// get out and in stream
DataOutputStream dout = new DataOutputStream(s.getOutputStream());
DataInputStream din = new DataInputStream(s.getInputStream());
dout.writeUTF("{FileList}" + fileList);
FileInputStream fis;
DataInputStream dataIn;
int length = 0;
ta.append(din.readUTF() + "\n");
state = "send";
// send file one by one
for(File f : fileList) {
dout.writeUTF("{FileBegin}" + f);
fis = new FileInputStream(f);
dataIn = new DataInputStream(fis);
byte[] buffer = new byte[1024];// 定义一byte类型的缓冲区
// send buffer length once
ta.append("File: " + f + " send begin!\n");
while ((length = dataIn.read(buffer)) != -1) {
dout.write(buffer, 0, length);
}
ta.append("File: " + f + " send end!\n");
dout.flush();
fis.close();
dataIn.close();
}
din.close();
dout.close();
s.close();
state = "rest";
}
catch(Exception exc) {
exc.printStackTrace();
}
}client:程序代码： public void receiveFile() {
state="receive";
try {
dout.writeUTF("{ReceiveFiles}");
// receive each file through one new socket
for(int i=0; i<list.length; i++) {
// read file name
String str = din.readUTF();
int j=str.lastIndexOf("\\");
// create file output
File f = new File(path.getPath() + "\\" + str.substring(j+1));
if(!f.exists())
f.createNewFile();
FileOutputStream fos = new FileOutputStream(f);
int length=0;
byte[] buffer = new byte[1024];
// read file buffer and write it into file f
ta.append("File: " + f + " receive begin!\n");
while ((length = din.read(buffer)) != -1) {
fos.write(buffer, 0, length);
}
fos.close();
ta.append("File: " + f + " receive end!\n");
}
din.close();
socket.close();
}
catch(Exception e) {
e.printStackTrace();
}
state="rest";
}
