Question

socket中Inputstream.read()方法出现问题，一直阻塞；

InputStream inputStream = socket.getInputStream();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte[] bytes = new byte[512];
int len = -1;
len = inputStream.read(bytes);
System.out.println(len + "====================");
outputStream.write(bytes, 0, len);
while ((len = inputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, len);
outputStream.flush();
}
bytes = outputStream.toByteArray();
System.out.println("=============结束了====================="
+ bytes.length);
inputStream.read()在读取完信息后，一直阻塞着，不走最后一句，也没有异常抛出？

Answer 1

InputStream inputStream = socket.getInputStream();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte[] bytes = new byte[512];
int len = -1;
len = inputStream.read(bytes);
System.out.println(len + "====================");
outputStream.write(bytes, 0, len);
while ((len = inputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, len);
outputStream.flush();
socket.shutdownOutput();
}
bytes = outputStream.toByteArray();
System.out.println("=============结束了====================="
+ bytes.length);

Answer 2

这个方法本身就是堵塞的，要等读到信息才继续往下走的

追问

那我应该怎样处理下？
