我已经看到很多将文件从服务器发送到客户端的示例。例如(在这里找到):
服务器:
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class Main {
public static void main(String[] args) throws IOException {
ServerSocket servsock = new ServerSocket(123456);
File myFile = new File("s.pdf");
while (true) {
Socket sock = servsock.accept();
byte[] mybytearray = new byte[(int) myFile.length()];
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(myFile));
bis.read(mybytearray, 0, mybytearray.length);
OutputStream os = sock.getOutputStream();
os.write(mybytearray, 0, mybytearray.length);
os.flush();
sock.close();
}
}
}
客户:
import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.Socket;
public class Main {
public static void main(String[] argv) throws Exception {
Socket sock = new Socket("127.0.0.1", 123456);
byte[] mybytearray = new byte[1024];
InputStream is = sock.getInputStream();
FileOutputStream fos = new FileOutputStream("s.pdf");
BufferedOutputStream bos = new BufferedOutputStream(fos);
int bytesRead = is.read(mybytearray, 0, mybytearray.length);
bos.write(mybytearray, 0, bytesRead);
bos.close();
sock.close();
}
}
有没有办法重写这个或类似的东西,以相反的方式使用,以便客户端可以将文件发送到服务器?
