节点JS服务器到服务器连接

是否可以从另一台服务器连接到NodeJS服务器?两个NodeJS服务器相互通信?

//Server Code
var io = require('socket.io').listen(8090);

io.sockets.on('connection', function (socket) {
io.sockets.emit('this', { will: 'be received by everyone'});

socket.on('private message', function (from, msg) {
   console.log('I received a private message by ', from, ' saying ', msg);
});

socket.on('disconnect', function () {
   io.sockets.emit('user disconnected');
  });
});

//Client Code in Server Code. Connecting to another server.
io.connect( "http://192.168.0.104:8091" );  //Connect to another server from this one.

//ETC...

如何在Android中使用Wifi获取位置?

我希望通过Wifi获取位置并在谷歌地图中工作,这对我不起作用,但Gps没问题,也没问题.

我的代码:

locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

if (locationManager != null) {
    boolean gpsIsEnabled = locationManager
            .isProviderEnabled(LocationManager.GPS_PROVIDER);
    boolean networkIsEnabled = locationManager
            .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    if (gpsIsEnabled) {
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, 5000L, 10F,
                (android.location.LocationListener) this);
    } else if (networkIsEnabled) {
        locationManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER, 5000L, 10F,
                (android.location.LocationListener) this);
    } else {
        // Show an error dialog that GPS is disabled...
    }
} else {
    // Show some generic error dialog because something must have gone
    // wrong with location manager.
