將datagramPacket轉換爲字符串

Question

我想創建一個android應用程序，該應用程序可以捕獲連接到我的網絡的設備發送的MDNS廣告。 我想要得到的響應，

NOTIFY * HTTP/1.1 
HOST: 239.255.255.250:1900 
CACHE-CONTROL: max-age = seconds until advertisement expires 
LOCATION: URL of the web page to advertise 
NT: urn:physical-web-org:device:Basic:1 
NTS: ssdp:alive 
SERVER: OS/version UPnP/1.0 product/version 
USN: advertisement UUID 

誰能幫我轉換響應像上面？

Answer 1

試試這個代碼

buffer = new byte[1024]; 
packet = new DatagramPacket(buffer, buffer.length); 
socket.receive(packet); 
buffer = packet.getData(); 
String packetAsString=new String(buffer, 0, packet.getLength()); 
Log.d("DatagramPacket","Received: "+packetAsString);
