server

问题 I have a web application that runs a query on an api, gets new information, changes the variables in the database and sends emails if needed (compares old and new variables). I work with Ubuntu Server, and I tried several variations to run this. my controller looks like this: class Cli_only extends CI_Controller { public function __construct() { parent::__construct(); is_cli() OR show_404(); // If cronjob ! $this->load->model('kas_model'); // Sets the server not to have a time out. ini_set(

问题 I am working on a web project, I just started using a JavaScript based video player in Wordpress. The video player works fine when using videos on the same server but when requesting videos from other servers it throws the error in browser console: Failed to load http://techslides.com/demos/sample-videos/small.mp4: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.gozo.kitchen' is therefore not allowed access I am trying to access the video on a

问题 I'm trying to protect my JavaFX code beyond that of ProGuard. I understand that any code that a user has in their possession is fair game. That means I need to move all my sensitive business logic onto a server which can be confidently protected. Due to my limited server-side experience I'm looking for an explanation/example of how to develop the client-server connection so it's secure and reasonably fast. My main confusion relates to what is required in the client-side code such as server

问题 I use autobahn framework to create a websocket server in python. I use the following code url = "ws://0.0.0.0:" + str(server_port) ServerFactory = MyServerFactory factory = ServerFactory(url, debug = True, debugCodePaths = True) factory.protocol = MyServerFactory factory.setProtocolOptions(requireMaskedClientFrames = False, applyMask = True) listenWS(factory) reactor.run() I need to accept connections not only on IP4 but IPv6 as well. In the same code I create a HTTP server using the

问题 I have this laravel application on /var/www/html/application-folder/public_html When I enter the apache server IP it doesn't load the laravel application instead it displays the Apache home page How can I display the url /var/www/html/application-folder/public_html ? When I type the full url I get the following error: Forbidden You don't have permission to access /folder/public_html/index.php on this server. Apache/2.2.15 (CentOS) Server 回答1: If you have full root access to your server then

问题 I'm curious about if there is some type of standard limit on when is better to use Ajax Polling instead of SSE, from a server side viewpoint. 1 request every second: I'm pretty sure is better SSE 1 request per minute: I'm pretty sure is better Ajax But what about 1 request every 5 seconds? How can we calculate where is the limit frequency for Ajax or SSE? 回答1: No way is 1 request per minute always better for Ajax, so that assumption is flawed from the start. Any kind of frequent polling is

问题 I have MacOS High Sierra and my goal is to run node web-applications without installation node on macos (I wanna use docker to do it). That web-application is usually angular-webpack (compilation + run dev serwer). Dockerfile : FROM node WORKDIR /work CMD while true; do sleep 10000; done EXPOSE 3002 The line CMD while ... makes that container will be not killed by docker after run it - this allow us to "login" into container (by docker exec -it... ). Bash script run.cmd which run container:

问题 I am developing a VB.net windows forms application. My application connects to a name specified computer on network and gets its MAC address and performs a check, in order to prevent the use of the application "out-of-office". The Mainpage load event is as follows: Private Declare Function inet_addr Lib "wsock32.dll" (ByVal s As String) As Integer Private Declare Function SendARP Lib "iphlpapi.dll" (ByVal DestIP As Integer, ByVal SrcIP As Integer, ByRef pMACAddr As Integer, ByRef PhyAddrLen

问题 I am writing an event collector http server which would be under heavy load. Hence in the http handler I am just deserialising the event and then running the actual processing outside of the http request-response cycle in a goroutine. With this, I see that if I am hitting the server at 400 requests per second, then the latency is under 20ms for 99 percentile. But as soon as I bump the request rate to 500 per second, latency shoots up to over 800ms. Could anyone please help me with some ideas
