routing

问题 My desired affect: When the page loads components A, B and C animate on independently The user clicks a link inside, say, component B Components A, B and C animate off independently A new page loads, more components animate on. This sounds simple but I'm struggling to make it happen. So far I have a number of routes setup using react-router v4 and I am using CSSTransitionGroup to add movement to routes and components. The problem I am having is: If a route is animated, I cannot seem to

问题 On Rails 3, I'm trying to redirect from a URL without a trailing slash to the canonical URL that has a slash. match "/test", :to => redirect("/test/") However, the route above matches both /test and /test/ causing a redirect loop. How do I make it match only the version without the slash? 回答1: You can force the redirect at the controller level. # File: app/controllers/application_controller.rb class ApplicationController < ActionController::Base protected def force_trailing_slash redirect_to

问题 I looked at subdomain-fu and it looks pretty easy to route all non-www and non-'' subdomain requests to a single controller. But I also, need to send all external domains that are CNAME'd to my domain to the same controller. I have done a lot of searching and I can't find anything. Summarized, if it is a subdomain on my domain it goes to Catchall controller, if it is any other domain than my domain, it goes to the same Catchall controller. I am going nuts on this, any help would be

问题 I'm trying to learn learn how routing works in Symfony2, and so far everything I've read has examples like this: blog: path: /blog/{page} defaults: { _controller: AcmeBlogBundle:Blog:index, page: 1 } This routes requests to /blog/123 to the AcmeBlogBundle Blog controller's "index" action, and passes the 123 parameter as the "page" parameter to that controller action. If no page parameter is passed, then the page defaults to 1. That's all well and good, but what if you want to simply have a

问题 I have a little Ionic 4 App with 2 Tabs and 1 Detail Page. The Problem I'm facing here is that if I go from Tab2 into Detail Page and from there with ion-back-button back it always redirect me to Tab1 instead of Tab2 where I was before. Here is my example: Tab2 Html: Here I have a simple ion-item with a click event: <ion-item class="chat-item" (click)='openChat()' > It calls the openChat funtion which works like this: openChat() { this.router.navigateByUrl('/chatdetail/:uid'); } Now it opens

问题 I want to build a ASP.NET MVC site so that the controller for a specific url is stored in the database instead of the URL. The reason for that is that i'm building a CMS system and the users should be able to change the template (controller) without changing the URL. I also think that the name of the controller is not relevant for the end users and i want clean URL:s. I realise that i could just add all routes at application start, but for a system with like 100 000 pages it feels like a bad

问题 In rails 2.3.5 you could do something like this inside the routes.rb file: map.root :controller => "pages", :action => "show", :id => 3 In rails 3 I haven't found any way to pass a specific parameter (like in rails 2.3.5 with :id => 3). I know I can handle it from the controller and have the same result (which I did), but I was wondering if there is a way to do the same thing in rails 3 from the routes.rb or has it changed because it is better practice for some reason? 回答1: Are you sure the

问题 If I have two internal computers connecting to the same external IP address through a NAT router, how is the router able to get the traffic to the correct internal computer? It is my understanding that NAT forwards incoming packets to the computer that recently sent outgoing packets to the [incoming packet's] sender's IP address. Since both computers are sending to the same address, does the router forward the packet to both? If that is the case, is it the responsibility of the client
