问题 I'm using Grails 2.4.3 and I have a <g:uploadForm> with method set to post, but I'm not getting a MutlipartRequest in my controller action. Instead I'm getting a Servlet3SecurityContextHolderAwareRequestWrapper which has not getFile() method. I've tried casting, I've tried getting the request out of the wrapper with request.request , and I've tried a bunch of other things I've seen suggested to others with a similar problem, but still no dice. I'm sure I'm missing something simple. I tend to

Managing file uploads in JSP/Servlets

由 余生颓废 提交于 2019-12-19 04:23:21
问题 Once again a very beginner-ish question, but here I go: I would like to use a servlet or similar to copy an uploaded file (from an html file select) to a permanent location. This is all I need to do with the file. I am currently going with using the Apache Commons FileUpload and IO libraries.

Codeigniter multiple file upload paths

由 早过忘川 提交于 2019-12-19 04:02:50
问题 I'm building an app which needs to take uploaded files and put them in separate directories for thumbnails and fullsize images. But $config['upload_path'] = './uploads/'; only allows me to select one upload path. How do I define two or more upload paths? 回答1: Actually all you need to do is "re-initialize" the upload class. Codeigniter does not allow you to call the class twice with new parameters (it ignores the second request), however you can tell the class to manually load new parameters.
