功能没有实现nodejs xmpp android

Question

我想创建一个聊天应用程序与出去使用谷歌消息服务和nodejs xmpp服务器。 因此，我使用了this node js xmpp server，并为android应用程序使用了api。

我不知道为什么，但服务器发送节说功能没有实现。

我写的连接xmpp服务器的android代码。

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder() 
        .setServiceName("localhost") 
        .setHost(IPADRESS) 
        .setPort(5222) 
        .build(); 
      AbstractXMPPConnection conn2 = new XMPPTCPConnection(config); 
      conn2.setPacketReplyTimeout(1000); 
      SmackConfiguration.DEBUG = true; 
      conn2.connect(); 

      conn2.login(mngr.getDeviceId(), "secret"); 

的NodeJS XMPP服务器模块

var startServer = function (done) { 
    // Sets up the server. 
    server = new xmpp.C2S.TCPServer({ 
    port: 5222, 
    domain: 'localhost' 
    }) 

    // On connection event. When a client connects. 
    server.on('connection', function (client) { 
    // That's the way you add mods to a given server. 

    // Allows the developer to register the jid against anything they want 
    client.on('register', function (opts, cb) { 
     console.log('REGISTER') 
     cb(true) 
    }) 

    // Allows the developer to authenticate users against anything they want. 
    client.on('authenticate', function (opts, cb) { 
     console.log('server:', opts.username, opts.password, 'AUTHENTICATING') 
     if (opts.password === 'secret') { 
     console.log('server:', opts.username, 'AUTH OK') 
     cb(null, opts) 
     } else { 
     console.log('server:', opts.username, 'AUTH FAIL') 
     cb(false) 
     } 
    }) 

    client.on('online', function() { 
     console.log('server:', client.jid.local, 'ONLINE') 
    client.send("") 

    }) 

    // Stanza handling 
    client.on('stanza', function (stanza) { 
     console.log('server:', client.jid.local, 'stanza', stanza.toString()) 
     var from = stanza.attrs.from 
     stanza.attrs.from = stanza.attrs.to 
     stanza.attrs.to = from 
     client.send(stanza) 
    }) 
    // Stanza handling 
    client.on('chat', function (stanza) { 
     console.log('server:', client.jid.local, 'chat', stanza.toString()) 
     client.send(stanza) 
    }); 

    // On Disconnect event. When a client disconnects 
    client.on('disconnect', function() { 
     console.log('server:', 'DISCONNECT') 
    }) 
    }) 

    server.on('listening', done) 
} 
startServer(function(){ 

    console.log("server localhost started at 5222 localport"); 
}); 

服务器的NodeJS控制台输出。

server localhost started at 5222 localport 
server: 354223060799129 secret AUTHENTICATING

我尝试了许多解决方案，用于计算器的相似类型的问题但没有work.help将不胜感激。

您链接的节点XMPP服务器项目不是完整的XMPP服务器。它是一个XMPP服务器库，可帮助您使用node.js构建XMPP服务器。

在您的日志中，当您尝试请求名单（联系人列表）时，它会返回未实现的异常。

您必须使用Javascript实现您需要的所有功能，或者选择另一个现有的功能完整的XMPP软件。
