How can I get the user's public IP if my server is behind a router? I'm trying: protected string GetIPAddress() { System.Web.HttpContext context = System.Web.HttpContext.Current; string ipAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; if (!string.IsNullOrEmpty(ipAddress)) { string[] addresses = ipAddress.Split(','); if (addresses.Length != 0) { return addresses[0]; } } return context.Request.ServerVariables["REMOTE_ADDR"]; } but all I get is the router gateway. Apparently, REMOTE_ADDR won't work in my case and neither will HTTP_X_FORWARDED_FOR . Any ideas on how to get the

Rails + SSL: Per controller or application-wide?

阅读更多关于 Rails + SSL: Per controller or application-wide?

问题 I could use some wisdom from any developers who have worked with Rails and SSL. I have a fairly simple app and I'm in the process of implementing payment processing. Obviously payment processing calls for SSL, so I'm setting that up now. My intention when I started working on this today was to find the simplest / cleanest way to enforce SSL on specific controller actions - namely anything having to do with payment. I figured there was no reason to run the rest of my site on SSL. I found the

问题 I would like to turn a primitive event (a click) into a semantic event, like "deleteTodo" This is described here, but not how to implement :( I have the following code: App.TodoView = Em.View.extend({ click: function(e) { this.trigger("deleteTodo"); } }); App.Router.map(function(match) { match('/').to('index'); }); App.IndexRoute = Ember.Route.extend({ deleteTodo: function(e) { // this code is never executed :( } }) ; After I perform the 'click', I see that the TodoView click function is

For example if I have following route organization: const appRoutes: Routes = [ { path: "", component: AppComponent, resolve: { app: AppResolver }, children: [ { path: "", component: NestedComponent, resolve: { subscribers: NestedResolver } } ] } ]; and following resolvers: export class AppResolver implements Resolve<any> { constructor(private appService: AppService) {} resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any> { return this.appService.getAppData(); } } export class NestedResolver implements Resolve<any> { constructor(private nestedService:

can one computer have two mac addresses?

I hope this was the right place to post this, sorry if it isn't. Also, I know next to nothing about networks. I'm trying to allocate bandwidth to different devices on my Linksys E1200 router. When I check my computer's MAC address, it comes back as 74:E5:0B:10:01:04 . I turned off everything in my apartment besides my xbox and notebook, and under the DHCP client table under my router settings I see the xbox along with " Owner-PC " and a MAC address of 00:21:6B:10:A8:6E . Is this my computer, and if so, why are there different MAC addresses? MAC Addresses are NIC specific.. Each Network

Angular2 Exploring Resolved Data in canActivate Guard?

阅读更多关于 Angular2 Exploring Resolved Data in canActivate Guard?

Is it possible to access resolved data of a route (-Resolver) inside a canActivate guard. Currently I can access the resolved data in the component by ngOnInit() { this.route.data .subscribe((data: { example: Array<Object> }) => { this.example = data.example; console.log('example resolver', this.example); }); } How could I manage that in the canActivate guard? This is not working: constructor(private route: ActivatedRoute) {} canActivate( route: ActivatedRouteSnapshot, state: RouterStateSnapshot, ): boolean { this.route.data .subscribe((data: { example: Array<Object> }) => { this.example =

Finding out distance between router and receiver?

阅读更多关于 Finding out distance between router and receiver?

问题 A general question: is it possible to retrieve information about how far away e.g. a computer is from a wifi-router. For instance I want to get data on my computer if I'm 10 meters away from my home-wifispot or 2 meters. Any idea if that is even possible? Edit: How about bluetooth? Is it possible to get information about how far away bluetooth-connected devices are one from another? 回答1: I would recommend a measuring line or just good-old-fashioned guesstimating. There is no "simple" way to

Multiple routers vs single router in BackboneJs

阅读更多关于 Multiple routers vs single router in BackboneJs

问题 All examples on Backbone I've seen use one router for the whole application, but wouldn't it make sense to have a router for each single part of your app (header, footer, stage, sidebar)? Has anyone built apps with more than one router and what are your experiences? Let's think about a complex app with nested views: Wouldn't it be better when a view has its own router that handles the display of the subviews, than having one big router that has to inform the main view to change its subviews?
