问题 I'm occurring some trouble writing a basic webserver in JAVA. It's currently working fine at delivering html or css files. But when it comes to images things are messed up. I assume I'm doing something wrong at reading the image-files and preparing them to be sent. But have a look at the code: public void launch() { while(true) { try { Socket connection = this.server_socket.accept(); ... PrintWriter print_writer = new PrintWriter(connection.getOutputStream()); String response = this.readFile

Concept of vert.x concerning a webserver?

廉价感情. 提交于 2021-01-28 23:51:45
问题 I don't quite get how vert.x is applied for a webserver. The concept I know for webserver is the thread-based one. You start your webserver, which then is running. Then for every client that connects, you get a socket, which is then passed to its own thread handler. The thread handler then processes the tasks for this specific socket. So it is clearly defined which thread is doing the work for which socket. However for every socket you need a new thread, which is expensive in the long run for

Angular 2 without Webserver

问题 How can I use Angular 2 in production without webserver and just the filesystem? I can't use a webserver because of the corporate policies (that was not a problem with Angular because I could use the filesystem). 回答1: If you don't need network, Angular (version 2 and higher) applications work with no problems over the file:/ protocol. But you must set a correct base href path in your index.html . If you are using Angular CLI, you can build the app using the following command: ng build --base

RuntimeError: threads can only be started once Python Tkinter webserver

问题 I am trying to create a webserver in python which can be started and stopped using a tkinter GUI. In tkinter I have a button which will call start() and a button that will call stop(). Initially everything works fine, the server starts when I click the button and it also stops when I click the stop button. When I try to restart the server again using the start button, I get a runtime error RuntimeError: threads can only be started once I believe it has something to do with the fact that I

PHP seems to execute script twice

问题 My web server is acting wierd. It seems like it executes scripts (PHP) twice before sending then to apache. I've run this file: <?php echo '<pre>'; session_start(); $_SESSION['index']++; echo '<br>'; print_r($_SESSION); ?> And I know that ++ will give a notice at first, but it's just to investigate if it runs twice. Anyway, the printed session shows that the index-index increases by two each time you load the page. The webserver is apache2, php5 installed on a debian unit. Anyone has any
