java实现http协议_java用http协议本地文件

对于那些感兴趣的人，这是一个片段 . 我能够通过Flux Launcher 而不是reactor-netty UDP类来实现 .

private static final String SSDP_IP = “239.255.255.250”;

private static final int SSDP_PORT = 1900;

private static final int TIMEOUT = 5000;

String request = new String(“example”);

byte[] receiveData = new byte[1024];

DatagramPacket sendPacket = new DatagramPacket(request.getBytes(),

request.getBytes().length, InetAddress.getByName(SSDP_IP), SSDP_PORT);

DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length,

InetAddress.getLocalHost(), SSDP_PORT);

Flux response = Flux.create(emitter -> {

try (DatagramSocket socket = new DatagramSocket()) {

socket.setSoTimeout(TIMEOUT);

socket.send(sendPacket);

while (true) {

socket.receive(receivePacket);

emitter.next(receivePacket.getData());

}

} catch (SocketTimeoutException e) {

emitter.complete();

} catch (IOException e) {

emitter.error(e);

}

})

.map(mapper -> new String(receivePacket.getData(), 0, receivePacket.getLength()))
