问题 I am seeing some strange behavior with my application and the state of its database file after running some tests that close the database, delete it, and replace it with a test fixture. When I examine the database file with a tool on my debugging PC, it doesn't match what the application itself seems to be reporting. It's possible that this strange behavior is related to this bug. I noticed that there are two files with the same base name as the database (with the normal .db extension.) The

问题 I am using the Amazon S3 API to upload files and I am changing the name of the file each time I upload. So for example: Dog.png > 3Sf5f.png Now I got the random part working as such: function rand_string( $length ) { $chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; $size = strlen( $chars ); for( $i = 0; $i < $length; $i++ ) { $str .= $chars[ rand( 0, $size - 1 ) ]; } return $str; } So I set the random_string to the name parameter as such: $params->key = rand_string(5

问题 I can't find a complete list of mime-type mappings on the internet. I would like to have a list that refers a file extension to every existing mime type. The list of all mime-types can be found here: http://www.iana.org/assignments/media-types but that resource doesn't include the file extension mapping. I googled a while and couldn't find a mapping list with all mime-types. Only lists with most common ones. In all lists I found for example this entry is missing: application/vnd

问题 I am trying to get a multiple upload library working for my Codeigniter based website. I have it working almost but I have a slight problem if I upload more than one image, the file extentions get screwed up; for example, if I upload three JPEGS, I get this in my uploads folder, image1.jpg image2.jpg.jpg image3.jpg.jpg.jpg I cannot see what is causing it, this is the library in question and I am pretty sure that it is in there that the problem is, <?php if ( ! defined('BASEPATH')) exit('No

问题 I was browsing the internet and noticed, YouTube, for example, contains a URL like this to denote a video page: http://www.youtube.com/watch?v=gwS1tGLB0vc . My site uses a URL like this for a topic page: http://www.example.com/page.php?topic_id=6f3246d0sdf42c2jb67abba60ce33d5cc .

问题 I have a simple ASP.NET Webapplication project with url-routing and want to "allow" routes with the fileextension like ".html", e.g... http://www.mywebsite.com/cms/test.html http://www.mywebsite.com/cms/sub/test.html http://www.mywebsite.com/cms/sub/sub/test.html My global.asax routes looks like this: routes.MapPageRoute("", "cms/{a1}", "~/default.aspx"); The route is matched with when i access the website like this: http://www.mywebsite.com/cms/test If i try this one, it doens't work too:

问题 I wanted to change the .php extension to .foo, to hide it for visitors. My webserver has cPanel installed, so I logged in and clicked on "MIME Types", and entered the following: MIME Type: application/x-httpd-php Extension: foo The problem is that it's not being parsed as PHP, but instead is downloaded (when you click the link, a file containing all the code of that file is being downloaded) How would I solve this? 回答1: Add in httpd.conf or vhost.conf <IfModule mime_module> AddType

问题 I'm outputting a tab-delimited file from my webapp that should be opened in Excel. The problem is that .xls seems not good for opening and editing it, then Excel required some other format, and if I change the extension to .tsv then the file becomes unknown for Excel (on Windows 7) and .csv is for comma-separated. Can you advice me which the file extension should be? This is the code that outputs the file and it works. It's just that I should choose the most suitable extension for tab

问题 I've created my own application in VB.NET that saves its documents into a file with it's own custom extension (.eds). Assuming that I've properly associated the file extension with my application, how do I actually handle the processing of the selected file within my application when I double click on the file in File Explorer?
