gevent flask in python

Question

I have a code..and a domain name, I like to use this code to display in my domain name

from flask import Flask
import gevent.wsgi

app=Flask(__name__)

@app.route('/')
def index():
        return "hello world"
app_server = gevent.wsgi.WSGIServer(('x.y.z.a'), app)
app_server.serve_forever()

It shows error:

Traceback (most recent call last):
  File "p.py", line 10, in <module>
    app_server = gevent.wsgi.WSGIServer(('184.171.170.27'), app)

    self.family, self.address = parse_address(listener)
  File "/usr/lib/python2.7/dist-packages/gevent/baseserver.py", line 323, in parse_address
    raise ValueError('Failed to parse address %r: %s' % (address, sys.exc_info()[1]))
ValueError: Failed to parse address '184.171.170.27': invalid literal 
for int() with base 10: '184.171.170.27'

What to do.. Thanks for helping

Take a look at gevent's baseserver.py at their github repo.

The address either needs to be a tuple containing the address and the port, or a string with a ":" separating the address from the port. I.e, these would be both valid

app_server = gevent.wsgi.WSGIServer('x.y.z.a:51515', app)

or

app_server = gevent.wsgi.WSGIServer(('x.y.z.a', 51515), app)
