Twisted Documentation: Serving Static Content From a Directory

The goal of this example is to show you how to serve static content from a filesystem. First, we need to import some objects:

Site, an IProtocolFactory which glues a listening server port (IListeningPort) to the HTTPChannel implementation:
```
1
from twisted.web.server import Site
```
File, an IResource which glues the HTTP protocol implementation to the filesystem:
```
1
from twisted.web.static import File
```
The reactor, which drives the whole process, actually accepting TCP connections and moving bytes into and out of them:
```
1
from twisted.internet import reactor
```

Next, we create an instance of the File resource pointed at the directory to serve:

1
resource = File("/tmp")

Then we create an instance of the Site factory with that resource:

1
factory = Site(resource)

Now we glue that factory to a TCP port:

1
reactor.listenTCP(8888, factory)

Finally, we start the reactor so it can make the program work:

1
reactor.run()

And that's it. Here's the complete program:

1
2
3
4
5
6
7
8
from twisted.web.server import Site
from twisted.web.static import File
from twisted.internet import reactor

resource = File('/tmp')
factory = Site(resource)
reactor.listenTCP(8888, factory)
reactor.run()

Bonus example! For those times when you don't actually want to write a new program, the above implemented functionality is one of the things the command line twistd tool can do. In this case, the command

twistd -n web --path /tmp

will accomplish the same thing as the above server. See helper programs in the Twisted Core documentation for more information on using twistd.
