问题 I am currently working on some web dev project in Java, i have implemented a frontcontroller, which job is to instantiate new controllers, depending on the path. So when the user is running ?q=user/login ex. the front controller should instatiate the UserController, that i am trying to do with this piece of code. String q = request.getParameter("q"); try { String[] page = q.split("/"); // Make first char upper, to match class name conventions. page[0] = (page[0].substring(0, 1).toUpperCase()

问题 I recently started working on a program in python which allows the user to conjugate any verb easily. To do this, I am using the urllib module to open the corresponding conjugations web page. For example, the verb "beber" would have the web page: "http://www.spanishdict.com/conjugate/beber" To open the page, I use the following python code: source = urllib.urlopen("http://wwww.spanishdict.com/conjugate/beber").read() This source does contain the information that I want to parse. But, when I

问题 I work on websites where accessibility is an absolute must have, we aim for at least AA standard. Typically we use resources such as https://contrast-ratio.com and https://contrastchecker.com to test a background colour against black or white text. In this instance let's take white (#fff) text at a size of 18px. Colour one: #546FAF has a ratio of 4.92 Colour two: #B349B1 has a ratio of 4.66 If I made a linear gradient between those two colours as a background, would #fff text at 18px be safe

问题 Can I use a HTML page as a Live Wallpaper? Or is it possible to capture a web page as an image and set it as a wallpaper? Any help would be greatly appreciated. 回答1: There is an app on the market called WebLiveWallpaper that does this. There is an option in it for how often to refresh the view of the web page, which leads me to believe that it is simply taking a snapsnot of the page and presenting it as an image some how. Unfortunately I wouldn't know how to go about setting that up. But I

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

问题 How does Django handle multiple users? I know that Apache creates a new thread and expressjs uses asynchronous methods. But I do not understand Django because it is working synchronously would'nt this slow down the process if there are more than say 2-3 users ? Thanks 回答1: Django is a WSGI application, which is a fundamental difference from a (WSGI) server such as Apache. Node.js/Express.js contains its own webserver to replace Apache. Django has to be served by a webserver of your choice.
