我正在学习Java套接字,并且想尝试仅使用套接字来实现XMPP库,但是我不知道该怎么做。我读过RFC,但一无所知。
我想实现这些功能:
据我所知,这意味着我可以成功地继续向服务器发送消息,但是如何?
public static void main(String[] args) {
String connect = "<?xml version='1.0'?> "
+ "<stream:stream "
+ "to='jabber.ru' version='1.0' "
+ "xmlns='jabber:client' "
+ "xmlns:stream='http://etherx.jabber.org/streams'>";
String msg = "<starttls xmlns=\"urn:ietf:params:xml:ns:xmpp-tls\">";
try {
InetAddress address = InetAddress.getByName(host);
Socket socket = new Socket(address, port);
socket.setKeepAlive(true);
OutputStream os = socket.getOutputStream();
OutputStreamWriter osw = new OutputStreamWriter(os);
BufferedWriter bw = new BufferedWriter(osw);
bw.write(connect);
bw.flush();
System.out.println("Message sent to the server : " + connect);
InputStream is = socket.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String message = br.readLine();
System.out.println("Message received from the server : " + message);
bw.write(msg);
bw.flush();
System.out.println("Message sent to the server : " + msg);
is = socket.getInputStream();
isr = new InputStreamReader(is);
br = new BufferedReader(isr);
message = br.readLine();
System.out.println("Message received from the server : " + message);
} catch (Exception exception) {
exception.printStackTrace();
}
}
注意:我不想使用任何库!因此Smack和其他人没有帮助。

在收到切换到TLS的确认后,您需要将套接字切换到TLS,并且不再使用明文。完成后,您只需打开流并开始协商序列即可。服务器将发送您的流功能,并且您将能够进行身份验证。
