java - 服务器在java中无法接收eof

Question

FileOutputStream fos = new FileOutputStream(fileName);
InputStream is = clientSocket.getInputStream();
while ((readBytes = is.read()) != -1)
{
    fos.write(readBytes);
    System.err.println(readBytes);
}
System.err.println(readBytes);
clientSocket.shutdownOutput();
fos.close();
System.out.println("Trans complete");

客户端发送-1，但服务器无法接收-1

我怎样才能得到所有文件？

Answer 1

在关闭 FileOutputStream 之前调用 flush()。
