功能没有实现nodejs xmpp android

2023年1月19日 202次阅读

我正在尝试使用Google消息服务和nodejs xmpp服务器创建聊天应用程序.

所以我使用
this node js xmpp server和smack api for android app.

我不知道为什么,但服务器发送节说没有实现的功能.

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");

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");
});

nodejs服务器控制台输出.

server localhost started at 5222 localport

我在stackoverflow中为类似的问题尝试了这么多解决方案,但没有work.help将不胜感激.

最佳答案 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.

您要么必须在Javascript中实现所需的所有功能,要么选择其他现有功能完整的XMPP软件.
