问题 I have a client iOS application that uses GCDWebServer to serve images and videos stored in the NSSearchPathDirectory.DocumentDirectory folder of the app on my device. Upon app startup, I start an instance of GCDWebServer and add a file response handler for my requests: self.addDefaultHandlerForMethod("GET", requestClass: GCDWebServerFileRequest.self) { request in return GCDWebServerFileResponse(file: self.filePathForResponse(request.URL)) } I can verify that while the app is running I can

问题 I want to build a simple website that can download a webpage www.example.com/index.html and store its snapshot on the server when the client requests. I'm thinking about using the command wget to download the webpage. Would Ruby on Rails be able to handle this task? 回答1: Yes. You can perform shell commands in Ruby via back ticks, exec and system. Note that each one returns something slightly different: back ticks wget http://www.yahoo.com exec : exec('wget http://www.yahoo.com') system :

问题 When you set a server environment variable in your Apache settings, it's possible to read that variable from PHP using built in functions. But can you read the variable from an htaccess file? What I'm trying to accomplish in my htaccess is something along the lines of: <If var=="stuff"> do things here </if> <if var=="different stuff"> do different things here </if> 回答1: Yes it is. You will probably want to use mod_setenvif functionality, so that module will need to be turned on. Then you

问题 I often use the following to quickly fire up a web server to serve HTML content from the current folder (for local testing): python -m SimpleHTTPServer 8000 Is there a reasonably simple way I can do this, but have the server serve the files with a UTF-8 encoding rather than the system default? 回答1: Had the same problem, the following code worked for me. To start a SimpleHTTPServer with UTF-8 encoding, simply copy/paste the following in terminal (for Python 2). python -c "import

问题 After reading about how gzip compression works it got me thinking. If the Origin and Proxy server (CDN) both support gzip is adding a Vary: Accept-Encoding header necessary? 回答1: The Vary: Accept-Encoding header has more to do with caching than compression. When the Vary: Accept-Encoding header is present, it tells the client that the file can be cached/is the same whether or not the client requests compression. If for some reason the client has an uncompressed version of the file in its

问题 How can a PHP script start another PHP script, and then exit, leaving the other script running? Also, is there any way for the 2nd script to inform the PHP script when it reaches a particular line? 回答1: Here's how to do it. You tell the browser to read in the first N characters of output and then close the connection, while your script keeps running until it's done. <?php ob_end_clean(); header("Connection: close"); ignore_user_abort(); // optional ob_start(); echo ('Text the user will see');

问题 The only place where I found informations on G-WAN web server was the project web site and it looked very much like advertisement. What I would really know is, for someone who is proficient with C, if it is as easy to use and extend that other architectures. For now I would mostly focus on scripting abilities. Are C scripts on GWAN easy to write ? Can you easily update and upload new C scripts to the server (say as easily than some PHP or Java pages on other architectures) ? Do you have to

问题 I now to ways to detect weather php script runs in cli or web server mode: if (defined('STDIN')) or: if (isset($argc)) Do they equally reliable or one of them is more ? 回答1: Neither. Check the value returned from php_sapi_name() . 回答2: $_SERVER['REQUEST_METHOD'] won't be set, due to the lack of a HTTP request. I think defined( 'STDIN' ) or isset( $argc ) are reliable too, though. If it was up to me, I'd probably go with the defined( 'STDIN' ), as I can imagine someone accidentally setting a
