get server address from bottle

Question

Is it possible to get the IP Address of the server programmaticaly in a bottle request?

I need to return a link to a file on the server inside a request and need to know the IP. Bottle will be started on a server with different IPs and all of these IPs will be serve requests.

currently i looks like this:

from bottle import *
import json
@get('/file')
def getAFileLink():
    # some logic here for the right filename to return
    # server runs now on e.g. 10.0.0.1 and 10.10.0.1
    # every client should see the IP from the server in the right subnet
    return json.dumps({'url': 'http://127.0.0.1:1337/some/file.abc'})

@route('/some/<filename>')
def getStaticFile(filename):
    return static_file(filename, root="/srv/static/files")

if __name__ == "__main__":
    run(host='0.0.0.0', port=1337)

Answer 1

Give a try to bottle.request.url ( docs ).

In case you need only scheme and hostname, use urlparse to get it.

Answer 2

If your servers aren't behind a load balancer, just use the Host HTTP header.

@route('/file')
def getAFileLink():
    host = bottle.request.get_header('host')
    return {'url': 'http://{}/some/file.abc'.format(host)}

Answer 3

you can use:

from bottle import request 
urlparts = request.urlparts
print urlparts.scheme
print urlparts.netloc

Answer 4

Why are you running your server on the same ip as the link that you return?

import socket
socket.gethostbyname(socket.gethostname())
