我正在尝试使用 JAVA 发送文件。我的问题是客户端永远不知道是否到达文件末尾。所以客户端的while循环永远不会结束。请帮我。
服务器(向客户端发送数据)
File myFile = new File("C://LEGORacers.exe");
byte[] mybytearray = new byte[(int) myFile.length()];
BufferedInputStream bis = null;
OutputStream os = null;
bis = new BufferedInputStream(new FileInputStream(myFile));
bis.read(mybytearray, 0, mybytearray.length);
os = socket.getOutputStream();
os.write(mybytearray, 0, mybytearray.length);
os.flush();
bis.close();
客户端(从服务器获取数据)
byte[] buf = new byte[1024];
InputStream is = null;
int bytesRead = 0;
is = client.getInputStream();
FileOutputStream fos = null;
fos = new FileOutputStream("C://copy.exe");
BufferedOutputStream bos = new BufferedOutputStream(fos);
try {
while (-1 != (bytesRead = is.read(buf, 0, buf.length))) {
// This while loop never ends because is.read never returns -1 and I don't know why...
bos.write(buf, 0, bytesRead);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
is.close();
bos.flush();
bos.close();
fos.close();
}
