问题 I got stuck recently with Angular route guards. CanActive runs only once when the page is loaded and does not run on route change within the guarded route. I think this was changed because it used to run on each change. From what I read in forums, I should use CanActivateChild. The thing is, our application consists of several modules, that have several route descendants and when I use CanActivateChild in root module, it is called several times when changing the route. I find it dumb to

问题 I was looking into raw sockets. so I created one raw socket client and other one is server. on two different computers. I am using ISP provided router. so I sent spoofed packet (with iphdr struct's saddr of different computer on same network) from client but when the packet received at the server the source ip in packet's ip header was correct (the real sender address=client address) plus the source port and destination port of tcphdr were something different too (which really didnt make

问题 I'm building an online gallery in React, and it requires an external script in order to work properly. There are 2 main components, namely Home.js and Single.js.

The Router looks like this: <Provider store={ store }> <Router forceRefresh={ false }> <div id="router"> <Switch> <Route exact path='/' render={ () => <MainLayout>

问题 Let's say I have two network interfaces: eth0 with address 10.0.0.1 eth1 with address 192.168.0.1 Using route or ip route add I have set it to route: All addresses to eth0 1.2.3.4 only to eth1 So packets to 1.2.3.4 should be routed to eth1 , and everything else to eth0 . I then create a UDP socket and use bind() to set its local address to 192.168.0.1 . Then I send a packet to 1.2.3.4 . Will it be be sent over eth1 per the routing table or eth0 because it is bound to that IP address? I tried,

问题 I have a page with ID, if I go to the same page through the Link https://localhost:8443/news/10 with another ID the page does not update props and state, and the page looks exactly the same as it was before you refresh it. I think this is because I do not change the state and props in the redux.
