我想将文件从服务器传输到客户端。在此之前，我想从特定目录发送文件名。当读取返回-1时，文件不会传输。任何一个人能纠正我在哪里出错？通过套接字传输字符串和文件
我的客户端代码是这样的。
import java.io.*;
import java.net.*;
class PC1Client {
public static void main(String args[]) throws UnknownHostException, IOException
{
byte[] aByte = new byte[1];
int bytesRead;
Socket sock = new Socket("localhost",3000);
InputStream is1 = sock.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is1));
String st = br.readLine();
System.out.println(st);
InputStream is = sock.getInputStream();
FileOutputStream fos = null;
fos = new FileOutputStream("F:\\ANI1.TXT");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
BufferedOutputStream bos = new BufferedOutputStream(fos);
bytesRead = is.read(aByte, 0, aByte.length);
System.out.println(bytesRead);
do {
System.out.println("s");
baos.write(aByte);
bytesRead = is.read(aByte);
} while (bytesRead != -1);
bos.write(baos.toByteArray());
bos.flush();
bos.close();
sock.close();
}
}
我的服务器代码是这样。
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
public class PC1Server {
public static void main(String[] args) throws IOException
{
ServerSocket serversocket = new ServerSocket(3000);
try
{
while(true)
{
String str="";
Socket socket = serversocket.accept();
File file = new File("D:\\ani");
for(File fi : file.listFiles())
{
str=str+fi.getName()+";";
}
PrintWriter outname = new PrintWriter(socket.getOutputStream());
outname.println(str);
outname.flush();
outname.close();
System.out.println("hello der");
BufferedOutputStream out = new BufferedOutputStream(socket.getOutputStream());
File myfile = new File("d:/hello.txt");
byte[] mybyte = new byte[(int)myfile.length()];
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(myfile));
bis.read(mybyte, 0, mybyte.length);
out.write(mybyte, 0, mybyte.length);
out.flush();
out.close();
}
}
catch(Exception e)
{
}
}
}
