Smack 4.4 yana ba da masana'antun ProxyInfo don HTTP, SOCKS4 da SOCKS5. Haɗa abin da aka samu zuwa maginin haɗin XMPP:

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.proxy.ProxyInfo;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;

ProxyInfo proxy = ProxyInfo.forSocks5Proxy(
    "proxy.example.net", 1080, proxyUser, proxyPassword
);

XMPPTCPConnectionConfiguration config =
    XMPPTCPConnectionConfiguration.builder()
        .setXmppDomain("chat.example.net")
        .setHost("xmpp-node.example.net")
        .setPort(5222)
        .setProxyInfo(proxy)
        .setSecurityMode(

Wannan guntun saiti ne don tsarin Smack 4.4 da ke akwai. Aikace-aikacen da ke kewaye yana kula da keɓancewar da aka bincika na maginin kuma yana ba da shaidar wakili. Mai karɓar da tashar da aka bayyana a fili suna wakiltar ainihin ƙarshen TCP na sabis ɗin XMPP.

Akwai sunaye uku masu ayyuka daban-daban:

• proxy.example.net shine mai shiga tsakani da ke karɓar haɗin farko.
• xmpp-node.example.net shine ƙarshen sabar da ake neman wakili ya isa.
• chat.example.net shine yankin sabis ɗin XMPP, kamar yankin bayan @ a cikin JID na asusu.
