Q:

Twisted non default root HTTP

So I want to have all of the urls start with "/files". 
The rootpage located at "localhost:3000/files" will return a list of specific folders that will be shared.  The default share does not let me limit what folders to share. 
I want to show all of the files in the folder when navigated to a folder.  With the URL like "localhost:3000/files/Documents".  
I want to share the specific folders and files in the folders recursively.  With the URL like "localhost:3000/files/Documents/Filename.pdf".  
from twisted.web.server import Site
from twisted.web.resource import Resource
from twisted.web.static import File
from twisted.internet import reactor

folder_list = ["Documents", "Downloads"]

class RootPage(Resource):
    isLeaf = True
    def render_GET(self, request):
        print request.uri
        new_request = request.uri[7:]
        if len(new_request) <= 3:
            ret = ""
            for folders in folder_list:
                ret += "<a href='%s'>%s</a></br>" % ("/files/" + folders.replace(" ", "-") , folders)
            return ret

root = Resource()            
#folders
root.putChild('files', RootPage())

for folders in folder_list:
    root.putChild( folders.replace(" ", "-"), File("/home/user1/" + folders))

factory = Site(root)

reactor.listenTCP(3000, factory)
reactor.run()

A:

Problems
1) In the .putChild() call, you establish your folder URLs as children of the root, not children of /files. 
2) In the RootPage class definition, you set isLeaf to True.  But you are creating an interior node, not a leaf node. 

Solution
Delete the isLeaf line, and change the other relevant lines to this:
root = Resource()
rootpage = RootPage()
#folders
root.putChild('files', rootpage)

for folders in folder_list:
    rootpage.putChild( folders.replace(" ", "-"), File("/home/user1/" + folders))

factory = Site(root)
