[Twisted-Python] How would I upload/download files through twisted.web

Fri May 9 17:37:09 MDT 2003

Not sure what you mean, but file upload may be done like so:

## fileup.rpy

import twisted.web.resource

class FileUpResource(twisted.web.resource.Resource):

     isLeaf = 1

     def render(self, request):
         request.setHeader('Content-Type', 'text/html; charset=utf-8')
         args = request.args
         pageTitle = 'file upload test'

         return (u"""
<html>
   <head>
     <title>%(pageTitle)s</title>
     <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
   </head>
   <body>
     <h1>%(pageTitle)s</h1>
     <form method="post" enctype="multipart/form-data">
     <table>
     <tr><td> file: </td><td> <input name='file' type='file'> </td></tr>
     </table>
     <input type=submit>
     </form>
     <hr/>
     <p>Form args:<br/>%(args)s</p>
     <hr/>
     </body>
</html>""" % vars()).encode()

resource = FileUpResource()
